Sensory nerves report information to the brain. It is a one-way communication from the body to the brain. Motor nerves respond by sending messages from the central nervous system (brain and spinal cord) to the body for movement. Motor nerves send messages in the opposite direction from the CNS to the body.
What are sensory nerves?
n. An afferent nerve conveying impulses that are processed by the central nervous system to become part of the organism’s perception of itself and of its environment.
What is the difference between sensory and motor neuron?
The main difference between sensory and motor neurons is that sensory neurons carry signals from receptors to the spinal cord and brain whereas motor neurons carry signals from the central nervous system to effector organs.
What are motor nerves called?
Motor neurons (also referred to as efferent neurons) are the nerve cells responsible for carrying signals away from the central nervous system towards muscles to cause movement.
What is motor nerve supply?
The motor nerve supplying the muscle is actually a bundle of axons from motor neurons carrying excitation to the muscle and sensory nerve fibers that return information to the central nervous system about the state of the muscle.
What are examples of motor neurons?
Types of lower motor neurons are alpha motor neurons, beta motor neurons, and gamma motor neurons. A single motor neuron may innervate many muscle fibres and a muscle fibre can undergo many action potentials in the time taken for a single muscle twitch.
