Which are sensory neurons

How do the neurons share the work?

With regard to their function in the nervous system, there are three types of neurons: sensory, motor and interneurons. They work together in all areas of stimulus reception, stimulus transmission and impulse processing.

Sensory neurons: This type of neuron transmits impulses from receptors in the skin, sensory organs, muscles and joints to the central nervous system. Some of the sensory neurons can be excited by direct stimuli such as cold, pressure or light. Most of the time, however, the excitement comes from stimuli from inside the body. The cell bodies of the sensory neurons are located in swellings called the posterior root ganglia, which are just outside the spinal cord. The axons of the sensory neurons extend into the spinal cord, where some are directly connected, others extend deep into the medulla of the central nervous system.

Motor neurons: The motor neurons conduct impulses from the central nervous system to the fulfillment organ, e.g. B. to muscles or glands that are stimulated to contraction or secretion. Although some of the motor neurons reside in the brain, from where they send their commands across the spinal cord, most neurons and their cell bodies reside within the gray matter of the spinal cord, from where their axons extend into the peripheral nerves of the muscles.

Interneurons: This type of neuron, also called switch neuron, makes up 90 percent of all neurons. Interneurons are thus the most common neurons in the central nervous system; in the brain alone there are at least 100 billion of these nerve cells. Interneurons are connected between sensory and motor neurons and enable the nervous system to transmit, evaluate and analyze nerve impulses.
