Document Summary

3. 2: how the nervous system works: cells and neurotransmitters. Neuron: major cell found in the nervous system responsible for sending and receiving messages throughout the body. Neurons receive input from one group of neurons and transmit it back out to other neurons. The (cid:374)euro(cid:374)"s (cid:449)ork together i(cid:374) thousa(cid:374)ds or e(cid:448)e(cid:374) (cid:373)illio(cid:374)s to finally put together some type of behaviour. Cell body/soma: part of the neuron that contains the nucleus that houses the (cid:272)ell"s ge(cid:374)eti(cid:272) (cid:373)aterial. The genetic material synthesizes proteins that form the chemicals and structures that allow the neuron to function, the activities of the genes are influenced by the input from other neurons. Dendrites: small branches radiating from the cell body that receive messages from other cells and transmit them towards the rest of the cell. When the dendrites receive and input the signal will travel across the neuron to the axon hillock.
