Document Summary

Function: sensory input: detects internal & external changes, integration: processes sensory info and decides on a response, motor output: if response required, ns sends message to respond. Central nervous system: brain & spinal cord, neurons: sensory, motor, interneuron. Receives info from receptors and transmits info to cns. Subdivided into: sensory somatic, visceral generally aren"t conscious; exceptions are present, motor (efferent): Transmits motor impulses from cns to muscles or glands. Subdivided: somatic voluntary, visceral motor (autonomic) Neuron structure: cell body, dendrites: extension of cytoplasm; direct info towards cell body, axon: extension of cytoplasm; direct info away from cell body. Regulate what substances come into contact with the neuron. Surround and separate cell bodies in ganglia. Regulate exchange of nutrients & wastes between neuron and their environment. Cortex outer covering; non myelinated, convoluted. Sulci grooves: longitudinal fissure: groove separating the hemispheres, central sulcus: separates frontal lobe from parietal, lateral sulcus: superiod border of temporal lobe, parieto-occipital sulcus: separates parietal and occipital.
