Dendrites are a part of the central nervous system that receive input from nerve cells, which are sometimes called. Multiple fibers called dendrites extend in a branchlike formation from the cell body of a neuron. When the postsynaptic terminals, or receptors, at the end of a dendrite receive neurotransmitters released by other neurons, an electric signal is transmitted through the dendrite to the cell body of the neuron.Know More
Dendrites receive nervous system signals through synapses, which form the connections between neurons where the axon terminal of one nerve cell ends near the dendrites of another nerve cell. Nerve cells do not physically touch each other. Instead, they communicate through the use of neurotransmitters that travel across the space called the synaptic cleft between the cells. An electrical signal travels down one neuron's axon and triggers the release of chemical compounds called neurotransmitters. Neurotransmitters move across the synaptic cleft and connect to the receptors on the other nerve cell. This triggers an electrical impulse that then travels from the dendrites to the cell body.
The typical neuron has thousands of dendrites, but it is possible for a nerve cell to have only one dendrite. Dendrites are relatively short, and they have spines that provide more surface area for other neurons to synapse with. Their branch-like formation inspired the name "dendrite," which means "tree" in Greek.Learn more about Nerves
The function of the myelin sheath is to facilitate the conduction of electrical impulses through the nerve cells. The myelin sheath is made out of a modified plasma membrane that is wrapped around the nerve axon in a spiral pattern.Full Answer >
In vertebrates, such as humans, the nervous system consists of two main components: the central nervous system and the peripheral nervous system, as noted by Inner Body. The brain and spinal cord make up the CNS, and the PNS includes the sensory neurons and nerves that link the CNS to other parts of the body. The main function of the nervous system is to transmit nerve signals throughout the body to coordinate its movement and various other activities.Full Answer >
The central nervous system, composed of the brain, spinal cord and an extensive neuron network, serves as the control center for all bodily functions. It functions as the transmitter and receiver as well as the pathway for information flow and determines how the body responds to changes in its internal and external environment.Full Answer >
The pia mater, the innermost membrane covering the central nervous system, protects delicate nerve tissue, supplies blood to the brain, and produces and circulates spinal fluid. It also connects different parts of the central nervous system to one another and provides support to the spinal cord.Full Answer >
