Anatomical terminology

The subscapular artery, the largest branch of the axillary artery, [1] arises from the third part of the axillary artery at the lower border of the subscapularis muscle, which it follows to the inferior angle of the scapula, where it anastomoses with the lateral thoracic and intercostal arteries, and with the descending branch of the dorsal scapular artery (a.k.a. deep branch of the transverse cervical artery if it arises from the cervical trunk), and ends in the neighboring muscles.

Contents

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. It terminates in an anastomosis with the dorsal scapular artery. [2]

<span class="mw-page-title-main">Scapula</span> Bone that connects the humerus (upper arm bone) with the clavicle (collar bone)

The scapula, also known as the shoulder blade, is the bone that connects the humerus with the clavicle. Like their connected bones, the scapulae are paired, with each scapula on either side of the body being roughly a mirror image of the other. The name derives from the Classical Latin word for trowel or small shovel, which it was thought to resemble.

<span class="mw-page-title-main">Subclavian artery</span> Major arteries of the upper thorax, below the clavicle

In human anatomy, the subclavian arteries are paired major arteries of the upper thorax, below the clavicle. They receive blood from the aortic arch. The left subclavian artery supplies blood to the left arm and the right subclavian artery supplies blood to the right arm, with some branches supplying the head and thorax. On the left side of the body, the subclavian comes directly off the aortic arch, while on the right side it arises from the relatively short brachiocephalic artery when it bifurcates into the subclavian and the right common carotid artery.

The deltoid muscle is the muscle forming the rounded contour of the human shoulder. It is also known as the 'common shoulder muscle', particularly in other animals such as the domestic cat. Anatomically, the deltoid muscle is made up of three distinct sets of muscle fibers, namely the

  1. anterior or clavicular part
  2. posterior or scapular part
  3. intermediate or acromial part
<span class="mw-page-title-main">Levator scapulae muscle</span> Slender skeletal muscle at the back and side of the neck

The levator scapulae is a slender skeletal muscle situated at the back and side of the neck. It originates from the transverse processes of the four uppermost cervical vertebrae; it inserts onto the upper portion of the medial border of the scapula. It is innervated by the cervical nerves C3-C4, and frequently also by the dorsal scapular nerve. As the Latin name suggests, its main function is to lift the scapula.

<span class="mw-page-title-main">Rhomboid minor muscle</span> Skeletal muscle of the upper back

In human anatomy, the rhomboid minor is a small skeletal muscle of the back that connects the scapula to the vertebrae of the spinal column. It arises from the nuchal ligament, and the 7th cervical and 1st thoracic vertebrae and intervening supraspinous ligaments; it inserts onto the medial border of the scapula. It is innervated by the dorsal scapular nerve.

<span class="mw-page-title-main">Teres minor muscle</span> Muscle of the rotator cuff

The teres minor is a narrow, elongated muscle of the rotator cuff. The muscle originates from the lateral border and adjacent posterior surface of the corresponding right or left scapula and inserts at both the greater tubercle of the humerus and the posterior surface of the joint capsule.

<span class="mw-page-title-main">Axillary artery</span> Large blood vessel bringing oxygenated blood to the thorax

In human anatomy, the axillary artery is a large blood vessel that conveys oxygenated blood to the lateral aspect of the thorax, the axilla (armpit) and the upper limb. Its origin is at the lateral margin of the first rib, before which it is called the subclavian artery.

<span class="mw-page-title-main">Axillary vein</span> Large vein between the thorax and the heart

In human anatomy, the axillary vein is a large blood vessel that conveys blood from the lateral aspect of the thorax, axilla (armpit) and upper limb toward the heart. There is one axillary vein on each side of the body.

<span class="mw-page-title-main">Lateral thoracic artery</span> Large blood vessel

In the human body, the lateral thoracic artery is a blood vessel that supplies oxygenated blood to approximately one-third of the lateral structures of the thorax and breast.

<span class="mw-page-title-main">Shoulder joint</span> Synovial ball and socket joint in the shoulder

The shoulder joint is structurally classified as a synovial ball-and-socket joint and functionally as a diarthrosis and multiaxial joint. It involves an articulation between the glenoid fossa of the scapula and the head of the humerus. Due to the very loose joint capsule ,that gives a limited interface of the humerus and scapula, it is the most mobile joint of the human body.

The thoracodorsal nerve is a nerve present in humans and other animals, also known as the middle subscapular nerve or the long subscapular nerve. It supplies the latissimus dorsi muscle.

The thyrocervical trunks are very small arteries of the neck arising from the subclavian arteries, lateral to the vertebral arteries. They divide into branches: the inferior thyroid artery, suprascapular artery, and the transverse cervical artery.

<span class="mw-page-title-main">Transverse cervical artery</span> Artery of the neck

The transverse cervical artery is an artery in the neck and a branch of the thyrocervical trunk, running at a higher level than the suprascapular artery.

The suprascapular artery is a branch of the thyrocervical trunk on the neck.

<span class="mw-page-title-main">Anterior humeral circumflex artery</span>

The anterior humeral circumflex artery is an artery in the arm. It is one of two circumflexing arteries that branch from the axillary artery, the other being the posterior humeral circumflex artery. The anterior humeral circumflex artery is considerably smaller than the posterior and arises nearly opposite to it, from the lateral side of the axillary artery.

<span class="mw-page-title-main">Scapular anastomosis</span> Circulatory system around the shoulder blade

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:

The thoracodorsal artery is a branch of the subscapular artery. It passes inferior-ward upon the suface of the serratus anterior muscle. It is accompanied by the thoracodorsal nerve along its source. It also supplies the latissimus dorsi.
