Study Notes

The Axillary Region

The brachial plexus, axillary artery, and axillary vein are enclosed in the axillary sheath.

Veins of the Head and Neck

The veins of the head and neck can be divided into two groups.
The external jugular vein is formed by the union of the posterior auricular vein and the posterior division of the retromandibular vein, behind the angle of the jaw.
The external jugular vein often receives the thoracic duct on the left side and the right lymphatic duct on the right side.
Relations of the external jugular vein:
- Anteriorly: The clavicle
- Posteriorly: The scalenus anterior muscle and the phrenic nerve
- Inferiorly: The upper surface of the 1st rib

Lymph Drainage of the Head and Neck

Lymph nodes of the head and neck are arranged in a regional collar that extends from below the chin to the back of the head.
A deep vertical terminal group of lymph nodes is embedded in the carotid sheath in the neck.
The efferent lymph vessels from the deep cervical lymph nodes join to form the jugular trunk, which drains into the thoracic duct or the right lymphatic duct.
