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.
