What nerve runs with the posterior circumflex humeral artery?
the axillary nerve
The posterior humeral circumflex artery (posterior circumflex artery, posterior circumflex humeral artery) arises from the third part of axillary artery at the lower border of the subscapularis, and runs posteriorly with the axillary nerve through the quadrangular space.
What artery travels around surgical neck of humerus?
posterior circumflex humeral artery
The posterior circumflex humeral artery arises medially from the axillary artery at the proximal part of the arm. It arises specifically from the third part of the axillary artery. It then immediately travels posteriorly and circles the surgical neck of the humerus via the quadrangular space 1.
What does the posterior circumflex humeral artery pass through?
The posterior circumflex humeral artery emerges from the third part of the axillary artery, at the inferior border of the subscapularis muscle. From its origin, it travels posteromedially with the axillary nerve, exiting the axilla through the quadrangular space.
Where is the humeral artery located?
The anterior circumflex humeral artery is located near the armpit. It branches from the axillary artery, on the side closest to the outside of the body. It runs alongside latissimus dorsi tendon. It also runs below the biceps’ two heads and the coracobrachialis.
What artery provides blood to the head and neck of the humerus?
Anatomy, Head and Neck, Posterior Humeral Circumflex Artery.
What is scapular 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: Transverse cervical artery.
What is a circumflex artery?
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 artery supplies the humerus?
anterior humeral circumflex artery
Background: The current consensus in the literature is that the anterolateral branch of the anterior humeral circumflex artery provides the main blood supply to the humeral head.
What nerve runs with circumflex scapular 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….Circumflex scapular artery.
| Origin | Subscapular artery |
|---|---|
| Branches | Muscular, infrascapular, articular, superior (horizontal) and inferior (parascapular) arteries |
What is the posterior circumflex humeral artery?
The posterior circumflex humeral artery is one of two circumflex humeral arteries that surround the surgical neck of the humerus. It arises from the third part of the axillary artery and supplies the shoulder joint and a number of its associated muscles.
What is the circumflex scapular artery?
Circumflex scapular artery (Arteria circumflexa scapulae) The circumflex scapular artery is the largest terminal branch of the subscapular artery. It courses through the posterior aspect of the shoulder, within the infraspinous fossa of the scapula. This artery gives off several muscular, cutaneous and articular branches.
Which artery anastomoses primarily with the suprascapular artery?
The superior, infraspinous branch of circumflex scapular artery anastomoses primarily with the suprascapular and dorsal scapular arteries. In turn, the inferior branch of circumflex scapular artery joins the dorsal scapular artery.
