What is the purpose of the motor nerves?
Motor neurons are the basic building blocks facilitating movement of the body. Without motor neurons, our body could not contract muscles and function. Motor neurons are responsible for both voluntary and involuntary body movements. Motor neuron diseases cause damage to the nerves innervating muscles and organs.
What are motor nerves called?
Motor neurons are also known as efferent neurons, meaning they carry information from the CNS to muscles, and other peripheral systems such as organs and glands. This contrasts with afferent neurons, or sensory neurons, which carry information from sensory organs and tissues back to the CNS.
What is motor nerve damage?
Motor nerve damage is most commonly associated with muscle weakness. Other symptoms include painful cramps, fasciculations (uncontrolled muscle twitching visible under the skin) and muscle shrinking. Sensory nerve damage causes various symptoms because sensory nerves have a broad range of functions.
What are motor neuron diseases?
The motor neuron diseases (MNDs) are a group of progressive neurological disorders that destroy motor neurons, the cells that control skeletal muscle activity such as walking, breathing, speaking, and swallowing.
What is difference between sensory and motor nerves?
A nerve contains bundles of nerve fibers, either axons or dendrites, surrounded by connective tissue. Sensory nerves contain only afferent fibers, long dendrites of sensory neurons. Motor nerves have only efferent fibers, long axons of motor neurons.

What is motor nerve and sensory nerve?
The main 2 types of nerves are sensory nerves and motor nerves. Sensory nerves also known as afferent nerves, carry impulses from sensory receptors towards the brain. Motor nerves also known as efferent nerves, carry impulses away from the brain to muscles and glands.
