NEET PG DENTAL EXAM

Detailed explanation-1: -The posterior root of the nerve carries sensory information into the posterior horn, often synapsing there. 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.

Detailed explanation-2: -The anterior horn cell is a motor neuron that projects from the anterior portion of the grey matter in the spinal cord to the skeletal muscle. The degeneration of these cells causes denervation of the muscles and weakness, the hallmark feature of this disease.

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.
