Question

____ nodes are located between the pectoralis major and minor muscles

A. axillary
B. inguinal
C. Rotter's
D. thoracic

Answer 1

Rotter's nodes are the lymphatic nodes found between the pectoralis major and minor muscles, contributing to the lymphatic system's function in the interpectoral region. The correct option is C.

Step-by-step explanation:

The nodes located between the pectoralis major and minor muscles are known as Rotter's nodes.

These nodes are part of the lymphatic system and are situated in the interpectoral region, which is the area between the pectoralis major, a thick and fan-shaped muscle covering much of the superior thorax, and the pectoralis minor, a muscle that assists in moving the scapula and aids in inhalation.

Both muscles play a crucial role in positioning and stabilizing the pectoral girdle, creating a base for the mobility of the shoulder and upper limb.
