Muscles attached to scapula

These muscles attach to the scapular surface and assist with abduction and external and internal rotation of the glenohumeral joint. Trapezius levator scapulae rhomboid major rhomboid minor serratus anterior pectoralis minor muscles.

It arises from the side and front of the first eight ribs.

Muscles attached to scapula. Superior spine of scapula. Spinal accessory efferent Ventral ramii C3 C4 afferent Elevates scapula Upward rotation of the scapula upper fibres. Downward rotation of the scapula lower fibres Retracts the scapula.

The scapula provides attachment sites for many muscles including the pectoralis minor coracobrachialis serratus anterior triceps brachii biceps brachii and the subscapularis. The scapula has two main surfaces. The costal front facing surface and the dorsal rear facing surface.

Muscles that originate from scapula. Deltoid supraspinatus infraspinatus triceps brachii long head teres minor teres major latissimus dorsi coracobrachialis biceps brachii subscapularis omohyoid muscles. Muscles that insert on the scapula.

Trapezius levator scapulae rhomboid major rhomboid minor serratus anterior pectoralis minor muscles. The scapula provides attachment for several groups of muscles. Scaplular muscles include the supraspinatus subscapularis teres minor infraspinatus deltoid and teres major.

These muscles attach to the scapular surface and assist with abduction and external and internal rotation of the glenohumeral joint. Anatomy of scapular muscles. Movements of the Scapula Movements of the scapula are carried by the scapular muscles.

The scapula can do six moves. Rhomboids and middle trapezius muscles. Upper trapezius and levator scapulae muscles.

Muscles attached to scapula. SSS TTTT BRR COLD LIP. Supraspinatus Supscapularis Serratus Anterior.

Trapezius Triceps Brachii Teres major Teres minor. Biceps brachii Rhomboid major Rhomboid minor. Coracobrachilalis Omohyoid Latissimus dorsi Deltoid.

Levator Scapulae Infrapsinatus Pectoralis minor. Muscles attached to the three foassae of scapula. Costal surface subscpular fossa.

Its medial two third provides origin to subscpularis muscle. Suprispinous fossa and upper surface of spine of scapula gives origin to supraspinatus muscle. Infraspinous fossa and inferior surface of spine of scapula gives origin to infraspinatus muscle.

Muscles attached to the three borders of. The shoulder has about eight muscles that attach to the scapula humerus and clavicle. These muscles form the outer shape of the shoulder and underarm.

The right scapula from the front and back side. The shoulder blade is a flat bone with three anglesthe upper superior bottom inferior and lateral glenoid angle and three bordersthe superior lateral axillary and medial vertebral border Picture 3. On the back side of the shoulder blade at about two-thirds of its height a bony ridge called the.

There is a total of 17 muscles connected to the scapula 11 of which originate from it whereas 6 others have it as a point of insertion. The muscles that originate from the vertebral column and are inserted into the scapula are the. Trapezius Levator scapulae Rhomboid major and Rhomboid minor.

Muscles Attached to the Scapula. As the scapula has a large surface area a large number of muscles get attached to it. The 17 muscles attached here fix the scapula to the thoracic wall and allow it to move.

Four muscles namely subscapularis infraspinatus teres minor and supraspinatus form the rotator cuff covering the shoulder capsule. Transverse middle fibers. The transverse middle fibers act together with the rhomboids to produce a retraction of the scapula by pulling it towards the midline.

The trapezius muscle is also responsible for upward rotation of the scapula along with the serratus anterior muscle. The intrinsic muscles of the scapula include the muscles of the rotator cuffthe subscapularis teres minor supraspinatus and infraspinatus. These muscles attach to the surface of the scapula and are responsible for the internal and external rotation of the shoulder joint along with humeral abduction.

The extrinsic muscles include the biceps triceps and deltoid muscles and attach to the coracoid process. Muscle Attachment of ScapulaThe scapula is a flat triangular-shaped bone that is known colloquially as the shoulder blade. Its location is in the upper thoracic region on the dorsal surface of the rib cage.

It connects with the humerus at the glenohumeral joint as well as the clavicle at the acromioclavicular joint to form the shoulder. How many muscles attach to the scapula. In mammals the scapula is attached to 17 muscles.

These muscles are responsible for rotating and stabilizing the shoulder joint. The scapula is See full answer below. The scapula articulates with the humerus at the glenoid fossa and the clavicle at the acromion process.

The scapula provides attachment sites for many muscles including the pectoralis minor coracobrachialis serratus anterior triceps brachii biceps brachii. Four muscles attach to the medial margin of the scapula - the serratus anterior levator scapulae rhomboid minor and rhomboid major. The lateral margin also lateral border or axillary border is the thickest of the three margins.

Three Muscles Attach to the Coracoid Process. Three muscles attach to the coracoid process the little bony projection of the scapula that sticks out just inferior to the acromioclavicular joint. These are just three of myriad muscles that attach to some aspect of the shoulder blade.

Pectoralis Minor is a small muscle deep to pectoralis major. 17 muscles attach to the scapula in alphabetic order. Biceps brachii both heads coracobrachialis.

Beside this which muscle inserts on the flat anterior surface of the scapula. Serratus anterior muscle its insertion is along the medial border from the superior angle to the inferior angle. This muscle protracts and rotates the scapula.

It is innervated by the long thoracic nerve. This big expanse of muscle is all serratus anterior. It arises from the side and front of the first eight ribs.

In runs back under the scapula and its inserted all the way back here along the medial border of the scapula. When the whole serratus anterior muscle contracts it pulls the scapula forward around the rib cage. The _____ is a narrow elongated muscle that is deep to both the trapezius and sternocleidomastoid muscles.

It attaches superiorly with multiple heads on the transverse processes of the cervical vertebrae and attaches inferiorly on the superior angle of the scapula.
