"We're just here to help, so don't worry too much about personal matters. Defeating the demons, this is your only purpose and heart!"

"Water God Gonggong, you are indeed very strong, but don't forget, the immortal's death hole - fairy bones, don't force us to do it!"

The shoulder blade is also called the blade and the lute bone. Behind the ribcage is an inverted triangular flat bone, between the second and seventh ribs.

It is divided into two faces, three corners, and three edges. The front is the subscapular fossa, which is a large and shallow fossa. There is a transverse bone crest at the back, called the scapula, and the shallow fossa above and below the spinatus are called the supraspinatus fossa and the infraspinatus fossa respectively.

The lateral side of the scapula is flattened and is called acromion.

The lateral angle is hypertrophied, with a pear-shaped articular surface, called the glenoid, and there is a small rough bulge above and below the glenoid, which is called the supraglenoid tubercle and the inferior glenoid tubercle respectively.

The upper and lower angles are located at the upper and lower ends of the medial margin, and are flat against the second and seventh ribs, respectively, and serve as landmarks for counting ribs.

There is a scapular notch on the outside of the upper border of the scapula, and the finger-like protrusion on the outside of the scapular notch is called the coracoid process because it resembles a bird's beak in shape, and the medial edge is long and thin, facing the spine, called the spinal margin.

The lateral margin is hypertrophied, facing the axillary rim, called the axillary margin. The shoulder blades, clavicle, and humerus make up the shoulder joint. The shoulder blades are located on the outer upper part of the back. The front of the scapula is slightly concave, and there is a high crest that goes outward at the back, called the scapula, and its lateral end is called the acromion, which is the highest point of the shoulder.

The scapula is palpable on the surface of the body. The movement of the scapula can be divided into six movements: upward lifting, downward suppression, external rotation, internal rotation, abduction and adduction. The clavicle moves with the scapula, except for the acromioclavicular joint, which occurs during rotational motion. When rotating upward, the lower angle of the scapula is more anterior outward than the upper angle, causing the glenoid to face up, and when rotating downward, the scapula moves with the humerus when the glenoid is facing down, and the scapula must rotate upward when the upper arm is abducted more than 90 degrees.

The abduction of the upper arm is not along the coronal plane, but at the first 30 to 45 degrees, called the scapular surface, and the glenoid must face anteriorly as the upper arm is flexed forward. The scapulohumeral joint and scapula movement are coordinated.

There is no joint structure between the scapula and the chest wall, and it is difficult for any muscle to contract to produce a single direction of movement of the scapula. Therefore, the movement of the scapula in any direction is done by the muscles that cooperate with each other but antagonize each other.

Most of the muscles involved in the movement of the scapula are directly attached to the scapula, but a few move indirectly through the movement of the humerus. Some muscles of the scapula are also involved in stabilizing the scapula, allowing the humerus to move smoothly.

Due to the triangular shape of the shoulder bone, the following scapula movements are based on the direction of the lower angle of the scapula.

Lift: It is acted by the upper fibers of the trapezius muscle, the levator scapulae muscle, and the rhomboid muscle majority, the former stretching the lateral angle of the scapula, and external rotation.

Except for the levator scapulae muscle, which originates from the transverse process of the cervical vertebrae, the other three muscles originate from the vertebral spinous process and the ligament, which can cause internal rotation of the scapula.

Lower suppression: Gravity itself can suppress the scapula, especially its lateral angle. Some of the muscles involved are attached to the scapula, while others are attached to the clavicle and humerus, and in the latter category, the lower fibers of the pectoralis major muscle and the entire latissimus dorsi act on the humerus, especially its lower fibers, which can also depress the scapula.

When induced upwards or supported with double crutches, the shoulder blades are prevented from going upward; The lower serratus anterior fibers, which attach to the lower angle of the scapula, and the lower trapezius muscles, which attach to the scapula, can also lower the scapula.

In addition to the above muscles, the pectoralis minor and subclavian muscles also play an auxiliary role. All of these muscles act primarily on the lower horn of the scapularis muscle. With the exception of the serratus anterior muscle, all other muscles rotate the scapula inward at the same time.

External rotation: predominantly the serratus anterior muscle, which pulls the inferior corner of the scapula forward to bring the medial edge forward. The serratus anterior muscle is also the trapezius muscle, whose upper fibers lift the lateral angle of the scapula and the lower fibers that pull the base of the scapula downward.

The serratus anterior muscle alone causes the scapula to be externally rotated, but the trapezius muscle alone cannot be externally rotated, but at the beginning of external rotation, it can support the lateral angle of the scapula, and only after the upper arm is abducted forty-five degrees, the serratus anterior muscle begins to contract, so that when the trapezius muscle is paralyzed, the scapula initially droops, and when the upper arm is abducted, the internal rotation is only seen after the serratus anterior muscle begins to act, and the elevation and external rotation are seen.

Internal rotation: includes the levator superioris attached to the spine border of the shoulder and the inferior suppressor pectoralis major muscle attached to the scapula and humerus.

Abduction: mainly serratus anterior, which can make the scapular spinal border close to the chest wall, and the helper still has the pectoralis major and pectoralis minor muscles. The pectoralis minor and serratus anterior muscles act in opposite directions in rotating the scapula, with the former rotating internally and the latter externally, but when acted together, the scapula can be abducted.

Adduction: participants have trapezius muscles, especially their middle fibers, rhomboids major and minor, and latissimus dorsi, especially their upper fibers.

It should be noted that although the serratus anterior and rhomboidus muscles are antagonistic in their actions, their combined action brings the scapula spinal border close to the chest wall.

The levator scapulae muscle arises from the transverse process of the cervical spine and moves the scapula upwards and forwards at the same time.

The rhomboid muscle, which attaches to the spinous process of the vertebrae, allows the scapula to move upwards and backwards.

Range of motion: During the movement of the scapula-chest wall, the trapezius and serratus anterior muscles must be intact, the upper fibers of the trapezius and serratus anterior muscles and the levator scapulae muscle should be considered as one unit, and the lower fibers of the trapezius muscle and serratus anterior muscle should be treated as another unit.

During forward flexion, the lower fibers of the trapezius muscle relax, allowing the scapula to slide forward, while the lower fibers of the serratus anterior muscle play a major role. The middle fibers of the trapezius muscle and the rhomboid muscle hold the scapula in place when the upper extremity is abducted, but relax when flexed forward, facilitating the movement of the scapula on the chest wall.

The abduction and forward flexion of the upper arm are due to the action of the scapulohumeral joint and the scapulothoracic wall joint. In the initial 30 degrees of abduction and 60 degrees of forward flexion of the shoulder joint, the scapula remains stable and does not move, only the scapulohumeral joint moves, but when the shoulder joint continues to abduct and flex forward, the scapulohumeral joint and the scapulothoracic wall joint move ratio is 2 to 1, that is, for every 15 degrees of elevation, the scapulohumeral joint moves 10 degrees, and the scapulothoracic wall joint moves 5 degrees.

The positive scapulothoracic arm has a 60-degree range of motion, and the scapulohumeral joint has a 120-degree range of motion, and the sum of the two is 180 degrees.

If the scapula is immobilized, the upper arm can only be actively raised to 90 degrees, passively raised to 120 degrees, and when the scapula is lost, the shoulder movement is at least one-third of the normal activity.

During forward flexion and abduction of the shoulder, movement of the scapula and humerus takes place simultaneously. The muscles of the upper levator scapula are innervated by the nerves and the superior fibers of the plexus, while the inferior suppressor muscles are innervated by the middle and lower fibers of the brachial plexus.

"Feathered Winged Immortal, are you threatening me, did my water god co-worker survive by giving in?"

As he spoke, his whole body quickly turned into divine water, and he became a water-attribute immortal, which was extremely terrifying.

The winged fairy's eyes were extremely sharp, and as soon as his body moved, he disappeared in an instant, and at the same time, something that seemed to be a brick but not a brick, a stone and not a stone was thrown together.

"Adobe?"

Gonggong is a well-informed immortal, with extraordinary natural eyesight, and knows that this thing specializes in the power of its own attributes.

"Gram me, think beautifully!"

Gonggong spoke, took a big mouthful, and spit out a stream of devastating divine water, completely covering the earth, stone and bricks.

The speed of the winged fairy is extremely fast, it has reached the speed of light, and it came to the back of the co-worker immortal in an instant.

"You're looking for death, Feather Winged Fairy!"

The strength of the co-workers is not inferior to the winged immortals, but the speed is not comparable at all.

All the immortal bodies of the co-workers turned into surging divine water, and the divine water continued to transform, turning into nine divine water dragons in the blink of an eye, three of which defended himself, and six of which were attacking.

At this time, the blind fairy made a move, he knocked the bamboo cane on the ground, and the ground under his feet shook, very violently.

Boom!

The ground exploded for no apparent reason, and a large pit appeared at the feet of the co-worker, trapping him in.

The winged fairy no longer left his hand, and acted at full speed, drilling through the gap between the six dragons, he raised his fist, and the power of the rules was fully revealed, poof...... Fight on the ground.

Gonggong was hit, but it didn't hurt like scratching an itch, and after the winged fairy took the opportunity to hold down Gonggong, the Turtle Spirit Holy Mother tied it tightly with a rope.

He freed his hand and made the hook knife penetrate the gonggong's pipa bone, which restrained the gonggong.

Isn't it possible to change co-workers, as long as they become small insects, they will be able to escape!

It seems that it is really possible, but what about the facts? In fact, from the moment the hook knife penetrates the pipa bone of the Gonggong, the Gonggong can no longer change.

Because the pipa bone is his life, and it is also the lifeline of all immortals.

As long as the pipa bone is pierced, no matter how great the supernatural power is, there is no way to use it! With the ability of co-workers, how can the pipa bone be pierced? And why can't you change and escape?

First of all, no matter what kind of immortal or demon it is, as long as it is pierced with the pipa bone, it can't change anymore, so the co-workers who are pierced with the pipa bone can't change, and they can't escape.
