Which are sensory nerves?

A sensory nerve, also called an afferent nerve, is a nerve that carries sensory information toward the central nervous system (CNS). It is a cable-like bundle of the afferent nerve fibers coming from sensory receptors in the peripheral nervous system (PNS).
A.

What is the difference between the sensory nerves and motor nerves?

Sensory neurons carry signals from the outer parts of your body (periphery) into the central nervous system. Motor neurons (motoneurons) carry signals from the central nervous system to the outer parts (muscles, skin, glands) of your body. Interneurons connect various neurons within the brain and spinal cord.
  • How are cranial nerves different from spinal nerves?

    Cranial nerves are the nerves that emerge directly from the brain (including the brainstem), in contrast to spinal nerves (which emerge from segments of the spinal cord). Cranial nerves relay information between the brain and parts of the body, primarily to and from regions of the head and neck.
  • How does a nerve impulse move through a neuron?

    When a nerve impulse reaches the end of an axon, the axon releases chemicals called neurotransmitters. Neurotransmitters travel across the synapse between the axon and the dendrite of the next neuron. Neurotransmitters bind to the membrane of the dendrite.
  • What part of the brain controls voluntary muscle movement?

    One of the brain areas most involved in controlling these voluntary movements is the motor cortex. The motor cortex is located in the rear portion of the frontal lobe, just before the central sulcus (furrow) that separates the frontal lobe from the parietal lobe.
B.

What do sensory nerves feel?

Sensory nerves. These nerves relay information from your skin and muscles back to your spinal cord and brain. The information is then processed to let you feel pain and other sensations.
  • Is nerve damage serious?

    Diabetic neuropathy is a serious complication and may affect all three types of neurons. Sensory nerves are most often affected, causing burning or numbness. If you have diabetes and are experiencing symptoms of nerve pain or nerve damage, you should consult a medical professional as soon as possible.
  • Can you heal from nerve damage?

    The peripheral nervous system can often heal itself from injuries. The central nervous system includes the brain and spinal cord. The peripheral nerves, however, have been given the miraculous capability to regenerate and repair themselves.
  • Is it possible to have permanent nerve damage?

    When a medical condition can be found and treated, your outlook may be excellent. But sometimes, nerve damage can be permanent, even if the cause is treated. Long-term (chronic) pain can be a major problem for some people. Numbness in the feet can lead to skin sores that do not heal.
