PSYC62H3 Chapter Notes - Chapter 2: Synaptogenesis, Apoptosis, Caudate Nucleus
Document Summary
Neurons: cells in the ns that receive and transmit information to other cells. Glial cells: cells that support the function of neurons: there are approximately 100 billion neurons and 10 times as many glial cells. Neuron networks support the function of individual brain structures and facilitate communication between basic structures. Interneuron: a neuron with the soma and the axon found within the same structure. Sensory neurons: neuron that conveys sensory information via axons to the central nervous system (afferent neurons) Motor neurons: neurons that convey motor information via axons leaving the central nervous system (efferent neurons) convey information to muscles in the body from the. Oligodendrocytes: glial cells that produce myelin around the axon of neurons. Myelin: insulating material that facilitates the movement of an action potential down the axon. Microglial cells: remove normal cellular waste from neurons and glial cells and also aid in gliosis. Peripheral nervous system: controlling and responding to physiological processes in the body.
