What muscles does the circumflex scapular artery supply?

What muscles does the circumflex scapular artery supply?

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. This article will discuss the anatomy and function of the circumflex scapular artery (scapular circumflex artery).

What does the circumflex scapular innervate?

Neuroanatomy of Acu-Reflex Points 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 does the suprascapular artery supply?

The suprascapular artery supplies the supra- and infraspinatus muscles and travels with the suprascapular nerve.

What does the circumflex artery supply?

The circumflex artery branches off the left coronary artery and encircles the heart muscle. This artery supplies blood to the outer side and back of the heart.

What does superior thoracic artery supply?

The main function of this artery is to provide blood supply for the pectoralis major, pectoralis minor, subclavius and serratus anterior muscles. Additionally, it supplies the muscles and adjacent skin of the first two intercostal spaces.

What does 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.

What is dorsal scapular artery?

The dorsal scapular artery is a branch of either the transverse cervical artery (from the thyrocervical trunk off the first part of the subclavian artery) or an independent branch from the third (or less commonly second) part of the subclavian artery.

What artery is above collar bone?

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 happens if the subclavian artery is blocked?

The symptoms that do occur are tied to the area that is blocked. You may experience arm pain or muscle fatigue when using your arms above your head, or doing any activity that demands more oxygen-rich blood flow to the arms. Other symptoms can include: Dizziness (vertigo) with arm activity.
