PATHOLOGY

Detailed explanation-1: -Neurons carry messages from the brain via the spinal cord. The neurons that carry these messages to the muscles are called motor neurons. Each motor neuron ending sits very close to a muscle fibre. Where they sit together is called a neuromuscular junction.

Detailed explanation-2: -For motor responses to be initiated, it requires sensory input to the brain. Various sensory information is relayed through the brainstem. Such tracts include: The dorsal column-medial lemniscus pathway, which relays sensory information related to fine touch, vibration sensation, and proprioception.

Detailed explanation-3: -Motor or efferent neurons transmit impulses from the central nervous system towards the effectors (muscle or glands), while sensory neurons transmit impulses from the sense organs towards the central nervous system (brain and spinal cord).
