Which nerves are responsible for innervating the pectoralis minor muscle?

The pectoralis minor muscle is innervated by the lateral and medial pectoral nerves. This muscle, located beneath the larger pectoralis major, plays a crucial role in stabilizing the scapula and assists with movements such as protraction and depression of the shoulder.

The lateral pectoral nerve originates from the lateral cord of the brachial plexus and primarily innervates the pectoralis major muscle, but it also provides innervation to the pectoralis minor through its branches. On the other hand, the medial pectoral nerve arises from the medial cord of the brachial plexus and directly innervates the pectoralis minor.

Understanding the specific roles of these nerves is important for medical professionals and students alike, as it relates to the function and possible injuries or conditions affecting the shoulder and chest region. The other choices do not provide the correct innervation, as they refer to different groups of nerves that innervate muscles unrelated to the pectoralis minor.
