Motor Neurons Whose Cell Bodies are Within the Spinal Cord

Question

Motor neurons whose cell bodies are within the spinal cord are called ________ neurons.
A) upper motor
B) lower motor
C) preganglionic
D) postganglionic
E) somesthetic

Accepted Answer

Lower motor neurons have their cell bodies located within the spinal cord and extend into the peripheral nervous system, innervating skeletal muscle fibers. Upper motor neurons, on the other hand, have their cell bodies located in the brain and synapse with lower motor neurons in the spinal cord. Preganglionic and postganglionic neurons are part of the autonomic nervous system and are not relevant to this question. Somesthetic neurons are sensory neurons that transmit information about touch, pain, and temperature.
