Document Summary

Each structure in brain has neurons and glial cells: neurons: receive and transmit info to other cells; principal players for behavior and are unique from other cells, glia(l): support functions of neurons. Neuron communication in ns: communication network in brain; supporting function of each brain structure and facilitate communication between them. Defining location of neuron and direction of axon. Interneuron: neuron with soma and axon found with the same structure. Afferent neuron: axon going to another structure: sensory neuron: convey sensory information via axon to cns. Efferent neuron: axon coming from another structure: motor neuron: convey motor info via axons from the cns. The ns: control of behaviour and physiological functions. Peripheral nervous system: controlling & responding to physiological processes in the body. 2 systems: peripheral nervous system, somatic nervous system, responsible for delivering voluntary motor signals from the. Hypothalamus: structure in forebrain and maintains important physiological conditions. When body needs food = elicits hunger.
