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 thousands of nerve endings in the human foot supply sensory feedback to the central nervous system, according to the Canadian Federation of Podiatric Medicine. The foot has more nerve endings per square inch than anywhere else in the body. Nerves constantly are sensing characteristics of the surface underfoot.Full Answer >
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.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 >
Bundles of nerve processes within the central nervous system are called fasciculi, tracts or funiculi, depending upon their size. All of these are types of neural pathways, cords of white neural matter that connect different parts of the nervous system.Full Answer >
