PSYC62H3 Chapter Notes - Chapter 2: Isotretinoin, Benzodiazepine, Cerebral Circulation
Document Summary
Neurons- cells in the ns that receive and transmit info to other neurons. Soma- body of the neuron that supports basic physiological processes; contains the nucleus (dna) They both contain receptors that nt"s can activate. Begins at axon hillock and ends with branches = axon collaterals. Axon terminal- contains and releases nts at postsynaptic terminal. Synapse- components that comprise the connection between 2 neurons. Interneuron- soma and axon found within the same structure. Sensory neurons- convey sensory info via axons to cns. Motor neurons- convey motor info via axons from the cns. Glia cells- support the function of neurons; more abundant. Oligodendrocytes- produce myelin around axons of neurons in cns. Schwann cells- produce myelin around axons of neurons in. Astrocytes- form the bbb to facilitate neuronal function and respond to injury. Bbb by forcing endothelial cells to fit tightly together. Act at synapses during neurotransmission by breaking down. Gliosis- involves swelling of glia cells in response to injury.
