Q:

What is the function of sensory nerves?

A:

Sensory nerves carry signals from organs that respond to stimuli to the spinal cord and brain. The information that travels from one point to another does so via the central nervous system.

The nerve cells that make up the sensory nerves are commonly known as sensory neurons. These particular neurons are one of three different types of neurons that are found within the body. The other two neurons are known as relay neurons and motor neurons. Relay neurons carry messages from on segment of the central nervous system to another while motor neurons carry signals from the central nervous system to effectors, which is an organ that has a particular effect when it is stimulated. The message that is relayed throughout this process is commonly known as an impulse, and it is sent along neuron pathways via electrical charges that move across the neural cell membrane.

    What are spinal nerves?

    A:

    A spinal nerve is part of the peripheral nervous system and carries motor, sensory and autonomic signals between the spinal cord and the body. Jim Swan of the University of New Mexico explains that the human spinal cord is divided into 31 segments, with nerve pairs forming at each segment.

  • Q:

    What is the function of a nerve ending?

    A:

    Sensory nerve endings detect stimuli from the environment and send impulses toward the central nervous system in response to these stimuli. Efferent nerve endings carry impulses from the central nervous system to effector organs and muscles. There are many different types of motor and sensory nerve endings, and each has its own unique function.

  • Q:

    What is the function of the motor nerves?

    A:

    Motor nerves are bundles of nerve cells that control muscles. They originate in the spinal column and end at the muscles that they control. One motor nerve often controls several muscles.
