What artery supplies subscapularis muscle?
What artery supplies subscapularis muscle?
The subscapularis muscle was supplied by the subscapular, suprascapular and circumflex scapular arteries. The supraspinatus and infraspinatus muscles were supplied by the suprascapular artery. The infraspinatus and teres minor muscles were found to be supplied by the circumflex scapular artery.
Where does the suprascapular artery go?
The suprascapular artery is a branch of the thyrocervical trunk, which emerges from the first part of the subclavian artery. It runs across the front of your neck and behind the clavicle (collarbone) to supply blood to the muscles, skin, and bones in your chest and shoulder.
What muscles does the dorsal scapular artery supply?
The dorsal scapular artery (DSA) supplies the levator scapulae and rhomboid muscles, and contributes to the arterial anastomosis around the scapula.
Does Subscapular artery supply to breast?
The lateral thoracic, acromiothoracic, and subscapular arteries are all branches or sub-branches of the axillary artery and may all contribute to the arterial supply of the breast.
What artery supplies deltoid?
The posterior circumflex humeral artery was the most important artery. It supplied the posterior and middle parts of the deltoid muscle. The anterior circumflex humeral artery supplied the anterior part of the deltoid muscle in 63%.
Does infraspinatus abduct?
Infraspinatus is the main external rotator of the shoulder joint. It assists in producing shoulder extension. With the arm fixed, it abducts the inferior angle of the scapula.
What does suprascapular artery anastomosis?
The scapular anastomosis is a system connecting certain subclavian artery and their corresponding axillary artery, forming a circulatory anastomosis around the scapula. It allows blood to flow past the joint in case of occlusion, damage, or pinching of the following scapular arteries: Suprascapular artery.
What artery supplies the infraspinatus?
The infraspinatus is supplied arterially by the suprascapular and circumflex scapular arteries. The suprascapular artery either originates from the thyrocervical trunk or the subclavian artery.
What does the dorsal scapular artery innervate?
The dorsal scapular nerve branches from the ventral ramus of C5 and descends from the cervical region down to the medial border of the scapula. It innervates three muscles: the levator scapulae, the rhomboid major, and the rhomboid minor.
What artery supplies the latissimus dorsi?
The muscle is supplied predominantly by the thoracodorsal artery, a continuation of the subscapular artery, a branch of the third part of the axillary artery.
What does the subscapular artery supply?
About 4 cm from its origin it gives off two branches, first the scapular circumflex artery and then the thoracodorsal artery….

What does the suprascapular artery do for the body?
The suprascapular artery provides blood—meaning oxygen and nutrients—to the muscles, skin, and bones it supplies. That keeps the tissues healthy and allows them to function properly. The muscles supported by the suprascapular artery include:
Where does the acromial branch of the suprascapular artery begin?
The acromial branch supplies blood to the skin covering the acromion of the scapula, a bony structure at the top of the shoulder blade. The suprascapular artery begins at the thyrocervical trunk (a branch of the subclavian artery) and goes across the phrenic nerve and a deep muscle located on each side of the neck called the scalenus anterior.
Where does the suprascapular nerve enter the scapula?
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.
Where is the suprascapular artery in New Jersey?
Scott Sundick, MD, is a board-certified vascular and endovascular surgeon. He currently practices in Westfield, New Jersey. The suprascapular artery is a branch of the thyrocervical trunk, which emerges from the first part of the subclavian artery.
