How Do You Spell PECTORAL NERVE?

1. The pectoral nerve refers to a vital nerve that is responsible for innervating certain muscles and providing sensory information in the pectoral region of the body. It is a branch of the brachial plexus, a network of nerves located in the shoulder and upper limb area.

   Specifically, the pectoral nerve comprises two main branches: the medial pectoral nerve and the lateral pectoral nerve. The medial pectoral nerve primarily supplies motor innervation to the pectoralis major and pectoralis minor muscles, which are crucial for movements such as shoulder adduction and depression, as well as protraction and rotation of the scapula. On the other hand, the lateral pectoral nerve provides motor innervation to the pectoralis major muscle, contributing to shoulder adduction and flexion.

   Additionally, the pectoral nerve provides sensory information to the skin in the pectoral region. It carries sensory fibers from the anterior chest wall, improving sensations like touch and temperature awareness in that area.

   Injuries or damages to the pectoral nerve can result in significant functional impairments. For instance, weakness or paralysis of the pectoral muscles, difficulty with shoulder movements, and a reduction in sensation in the anterior chest wall may manifest. Medical professionals consider these factors when diagnosing and treating conditions affecting the pectoral nerve.
