These cells aid the exchange of chemicals and help control neurotransmitter levels at synapses. Nerves are made up of cable-like bundles of nerve cells (neurons) and each neuron has three main parts, these are: 1. dendrites. Sensory neurons receive information via their receptors, which are part of the peripheral nervous system, and convert this information into electrical impulses. They essentially work to care for the neurons and the environment they are in. Neurons can simultaneously receive and integrate stimuli (impulses) either from the body or other sources. Neurons secrete chemical neurotransmitters which are responsible for stimulating other neurons as a result of a stimuli.

Neurons are typically classified into three types based on their function. Now if a neurons myelin sheath gets damaged or it doesnt get enough myelin sheath, the circuit is bound to not work properly. Without enough of this sheath, the axons, and sometimes the entire neuron, becomes extremely susceptible to degeneration. This leads to neurological symptoms such as Multiple Sclerosis (MS).

Crustacean neurons, obtained from the cerebral ganglion of the mud crab Scylla paramamosain, were successfully cultured in vitro. Neurons are responsible for transmitting signals throughout the body, a process that allows us to move and exist in the world around us. The astrocytes are not involved in immune defense and instead form a strong connection with blood capillaries in the brain and spinal cord. This sheath protects the nerves from damage and also acts as a barrier between the cells. At first, Alzheimers disease typically destroys neurons and their connections in parts of the brain involved in memory, including the entorhinal cortex and hippocampus.

They have an exceptionally high metabolic rate. Neurons are classified as either motor, sensory, or interneurons. Motor neurons carry information from the central nervous system to organs, glands, and muscles. Sensory neurons send information to the central nervous system from internal organs or external stimuli. Interneurons relay signals between the motor and sensory neurons. Sleep is associated with a typical posture, such as lying down with eyes closed in humans.
