Cells that are specialised to conduct electrical impulses
1 of 10
Soma
A cell body containing a nucleus
2 of 10
Dendrites
Parts of the neuron that conduct nerve impulses towards the soma or cell body.
3 of 10
Axon
A part of the neuron that conducts nerve impulses away from the cell body or soma.
4 of 10
Sensory Neurons
Neurons within the peripheral nervous system that respond to stimulation by sensory receptors and send signals towards the brain and spinal cord.
5 of 10
Axon Terminals
These are found at the end of an axon; they allow electrical impulses to pass from one neuron to the next.
6 of 10
Motor Neurons
Neurons within the peripheral nervous system that send signals away from the central nervous system to the muscles or glands.
7 of 10
Rekay Neurons
Neurons within the central nervous system that receive input from sensory neurons or other relay neurons and send impulses to motor neurons or other relay neurons.
8 of 10
Synapses
The extremely small junctions between adjacent neurons where nerve impulses are relayed.
9 of 10
Neurotransmitters
Chemicals that cross synapses and affect the receptors or adjacent neurons.
