Anatomy of the upper extremities blood vessels

2021-02-09 12:00 AM

The thoracic ring is due to the external thoracic artery and the thoracic artery connecting the inner thoracic artery and the upper intercostal artery of the subclavii artery.

Upper limb artery

The upper extremities are supplied with blood by the axillary artery, the arm artery, the spindle and the cylindrical artery and their branches.

Armpit artery

Pathway: the axillary artery is the continuation of the subclavii artery, from the midpoint of the posterior clavicle to the lower margin of the large pectoral muscle, renamed to the brachial artery.

Side branch: has 6 branches:

The upper chest artery, which supplies blood to the chest muscles.

Artery with chest shoulder, supplying blood to the shoulder and chest.

The external chest artery supplies blood to the chest wall.

The artery under the shoulder, supplying blood to the posterior wall of the armpit.

The anterior arm cap artery and the posterior arm cap go into the black-ta, joined around the arm bone surgery neck.

The axillary artery normally connects to the subarachnoid and brachial arteries, making up three loops around the shoulder, around the chest and in the arm area.

The thoracic ring is due to the external thoracic artery and the thoracic artery connecting the inner thoracic artery and the upper intercostal artery of the subclavii artery.

The around shoulder ring is caused by the inferior artery connecting the upper shoulder artery and the posterior artery of the subarachnoid artery.

The arm ring is caused by the anterior axial artery connected to the posterior cervical artery and the deep brachial artery of the brachial artery.

Since the two rings around the shoulder and around the chest are not connected to the arm ring, it is very dangerous to constrict the axillary artery between the anterior dorsal artery and the inferior artery.

Arm artery

Path: following the axillary artery, going from the lower margin of the large chest muscle to under the 3cm elbow folds, then divided into two branches, the rotating artery and the cylindrical artery.

Side branch: includes main branches:

Deep arm artery: to the posterior arm area.

The artery in the upper column, along with the pivotal nerve, runs downwards.

The artery underneath the pillar.

Arteries

Pathway: the cylindrical artery is the extremities of the arm artery, starting at 3cm below the elbow fold, running down the wrist and into the palmar to create a shallow artery.

Lateral branches: Lateral branches that nourish the forearm and hand area. Among them is a deep hepatic artery connected to the rotating artery creating a deep hepatic artery.

The artery spins

Paths: from 3cm below the elbow fold, the rotating artery running downwards, located in the rotating artery groove, then around the rotating crown, through the anatomical hollow of the crown to enter the palms of the hand, creating a deep arch.

Lateral branches: Lateral branches that nourish the forearm and hand area. Among them is the shallow palmar branch connected to the cylindrical artery creating a shallow artery.

The liver artery is shallow

Because the cylindrical artery connects to the shallow palmar branch of the rotating artery.

Lateral arm: for the branches that nourish the hand and fingers.

Deep hand liver artery

Structure: by the rotating artery connected to the deep palmar branch of the cylindrical artery.

Lateral arm: for the branches that nourish the hand and fingers.

Upper limb vein

Deep veins

From the bottom to the arm usually have two deep veins accompanying the arteries of the same name. To the armpits, they re-enter the axillary vein.

Superficial veins

In the subcutaneous fat layer of the forearm, there is a rich network of veins. This network of veins poured into three superficial veins in the order from the inside out the basilar vein, the vein between the forearm, the head vein. These veins travel up to the elbows to contribute to the vein network. Then the head and basilar veins continue to run upwards into the axillary vein.
