GENERAL HISTOLOGY

Detailed explanation-1: -This group of nodes receive lymphatic drainage from the skin and subcutaneous layer of the forearm and drain into the brachial axillary lymph nodes of the arm via efferent vessels. Cubital lymph nodes situated superior to the medial epicondyle of the humerus are known as the supratrochlear nodes.

Detailed explanation-2: -The supratrochlear lymph nodes swell up when an infection is detected in the hand or forearm areas. They may be palpable.

Detailed explanation-3: -Lateral (humeral) lymph nodes are over the lateral wall of the axilla. They receive lymph from the arm and drain into the central, apical, and deep cervical nodes. Central lymph nodes appear in the base of the axilla.
