THORAX ABDOMEN AND PELVIS

Detailed explanation-1: -The motor neurons that control limb and body movements are located in the anterior horn of the spinal cord, and the motor neurons that control head and facial movements are located in the motor nuclei of the brainstem.

Detailed explanation-2: -The anterior horn contains the cell bodies of somatic motor neurons, and it sends its axons out the anterior root of the spinal nerve to the muscle cells it innervates. The lateral horn is not found at all levels of the spinal cord, but is limited to thoracic and lumber segments of the cord.

Detailed explanation-3: -The somatic motor system The cell bodies of these neurons are present in the motor nuclei of the cranial nerves of the brain stem and in the anterior horn of the spinal cord.

Detailed explanation-4: -Somatic motor neurons. Somatic MNs are located in the Rexed lamina IX in the brainstem and the spinal cord and innervate skeletal muscles responsible for movements (Rexed, 1954). MNs form coherent groups connecting to a unique muscle target defined as MN pools.
