Document Summary
Neurons = nerve cells specialized for communication with each other releasing neurotransmitters. Soma (cell body) is the central region of the neuron. Dendrites = brancklike extensions for receiving information from other neurons. Axons = send messages to other neurons. Synaptic vesicles = travel the length of the axon and bursts at the end, Neurotransmitters = chemical messengers that neurons use to communicate. Synapse = tiny fluid-filled space between neurons through which transmitters. Synaptic cleft = a gap into which neurotransmitters are released from the axon with each other travel terminal. Glial cells = perform a variety of functions, play a key role in neural transmission. Myelin sheath = contains numerous gaps along the axon called nodes, which help the neuron conduct electricity more efficiently occur they"re how neurons communicate. Resting potential = when there are no neurotransmitters acting on the neuron. Action potentials = universal language of neurons in humans and all other animals;
