What 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 does the scapular circumflex artery supply?
This artery gives off several muscular, cutaneous and articular branches. 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 does thoracodorsal artery supply?
The thoracodorsal artery supplies predominantly the latissimus dorsi muscle but also gives branches to the serratus anterior muscle, the axillary skin, the subscapular and teres major muscles.
What does the suprascapular artery branch into?
As the artery passes over the superior transverse scapular ligament, it sends a branch into the subscapular fossa, where it ramifies beneath the subscapularis, and anastomoses with the subscapular artery and with the dorsal scapular artery.
What does the axillary artery supply?
The axillary artery supplies the walls of the axilla and related regions and continues as the brachial artery, to supply to more distal parts of the upper limb. The axillary artery is also divided into three segments based on its relationship to the pectoralis minor muscle: proximal, posterior, and distal.
What passes through suprascapular foramen?
The suprascapular nerve passes through the notch beneath the superior transverse scapular (suprascapular) ligament, which bridges the notch. The suprascapular artery and vein pass directly over the nerve above the ligament.
What does the posterior humeral circumflex artery supply?
The posterior circumflex humeral artery typically supplies the shoulder joint, deltoid muscle, teres major muscle, teres minor muscle, and the long and lateral heads of the triceps muscle.
What does thoracodorsal artery innervate?
Along its course, this artery gives rise to small branches that supply the following muscles: The serratus anterior muscle….Thoracodorsal artery.
| Origin | Subscapular artery |
|---|---|
| Branches | Lateral and medial branches, cutaneous branches |
| Supply | Latissimus dorsi muscle, serratus anterior muscle, subscapularis muscle, teres major muscle, axillary skin |
What artery supplies rhomboids?
dorsal scapular artery
The rhomboids are important in upper limb movement and stability of both the shoulder girdle and scapula. Both rhomboids receive innervation from the dorsal scapular nerve and supplied by the dorsal scapular artery.
What does subscapular artery Anastomose with?
It terminates in an anastomosis with the dorsal scapular artery.
What does the subclavian artery supply?
The subclavian arteries lie just below the clavicles, providing blood supply to the bilateral upper extremities with contributions to the head and neck.
What is Conoid tubercle?
The conoid tubercle also known as the coracoid tuberosity (not to be confused with the coracoid process of the scapula) is a bony prominence on the inferior surface of the lateral third of the clavicle.
What is the function of the suprascapular notch?
The supra scapular notch is situated in the lateral part of the superior border of the scapula, adjacent to the base of the coracoid process. The notch is converted into a foramen by the transverse scapular ligament and it serves as a passage for the suprascapular nerve.
What does the anterior circumflex artery supply?
The anterior circumflex humeral artery provides part of the blood supply to the glenohumeral joint, teres major and minor, and deltoid muscles. The ascending branch provides supply to the head of the humerus 1.
What does the Suprascapular nerve innervate?
The suprascapular nerve has a motor and sensory innervation. Its motor innervation is to the supraspinatus and infraspinatus muscles. The supraspinatus and infraspinatus muscles are two of the four muscles that make up the glenohumeral (shoulder) joint.
