What muscle does subscapular artery supply?
The main function of the subscapular artery is to provide blood supply for the muscles and skin of the shoulder, upper extremity and thoracic wall. The supplied muscles include the deltoid, latissimus dorsi, long head of triceps brachii, subscapularis, supraspinatus, infraspinatus and serratus anterior muscles.
What nerve runs with subscapular artery?
It courses posteriorly to the suprascapular notch of the scapula, accompanied by the suprascapular artery. The nerve passes through the notch deep to the transverse scapular ligament, whereas the artery passes over the ligament. The suprascapular nerve then travels deep to the supraspinatus, which it innervates.
What are the 2 branches of the subscapular artery?
About 4 cm from its origin it gives off two branches, first the scapular circumflex artery and then the thoracodorsal artery. From the thoracodorsal artery it supplies latissimus dorsi, while the scapular circumflex artery participates in the scapular anastamosis.
What is subscapular?
Description. The subscapularis muscle is a large triangular shaped muscle that originates from the subscapular fossa. The term “subscapularis” means under (sub) the scapula (wingbone). It is part of the four rotator cuff muscles, the other three are the supraspinatus, infraspinatus and teres minor muscles.
What does the circumflex Subscapular artery supply?
The circumflex scapular artery is the largest terminal branch of the subscapular artery. They contribute to the blood supply of three muscles (deltoid, teres minor, triceps brachii), glenohumeral joint and two small cutaneous areas partially overlying the scapula.
What arteries supply breasts?
Blood is supplied to the breast from the following vessels:
- The thoracoacromial artery.
- Internal mammary perforators (second to fifth)
- Lateral thoracic artery.
- Thoracodorsal artery.
- Terminal branches of the intercostal perforators (third to eighth)
What is the subscapular?
The subscapularis is the largest, strongest muscle of the rotator cuff. The rotator cuff muscles are important in shoulder movement and help maintain glenohumeral joint stability. The subscapularis muscle lies at the anterior surface of the scapula.
What artery supplies serratus anterior?
Serratus anterior muscle
| Serratus anterior | |
|---|---|
| Artery | lateral thoracic artery, superior thoracic artery (upper part), thoracodorsal artery (lower part) |
| Nerve | long thoracic nerve (from roots of brachial plexus C5, 6, 7) |
| Actions | protracts and stabilizes scapula, assists in upward rotation. |
What is subscapular region?
The term “subscapularis” means under (sub) the scapula (wingbone). It is part of the four rotator cuff muscles, the other three are the supraspinatus, infraspinatus and teres minor muscles. The subscapularis is the largest and strongest muscle of the rotator cuff.
