Document Summary
Neurons: nerve cells specialized to communicate with each other. What happens when neutrons die? won"t send messages as fast. Central region of the neuron; builds new cell components (cell body contains the nucleus, where proteins are manufactured, damage to this part neuron is fatal) Branchlike extension that receive information from other neurons. Tails of the neuron that spread out from the cell body and transit information (tail-like extensions that stick out of the cell body. ) Myelin sheath: fatty coat that insulates the axons of some nerve cells, speeding transmission of impulses. Axon terminal: know like structure at the end of the axon, containing synaptic vesicles. Synaptic vesicles: contain the chemical messengers known as neurotransmitters used to communicate with each other. Produced by cell body, sv"s travel down the axon until bursting at the at, releasing neurotransmitters. Tiny fluid-filled space between neurons through which neurotransmitters travel, and also consisting a synaptic cleft.
