Document Summary

!2: dendrites: info-receiver and brings it to cell body, axon: info-carrier, brings it to other neurons, muscles, and glands, covered by myelin sheath: fatty layer of glial cells, support cells from ! nervous system! Glial cells: help digest dead neurons, give physical/nutritional ! support, and help axon transfer info more ef ciently: synapse: space b/w axon of sending neuron and dendrite of receiving neuron! Neurons: cells in nervous system that talk to each other to perform info-processing tasks! Sensory neuron: receive info from outside world and conveys info to brain via spinal cord; specialized dendrites to receive signals for light, sound, touch, taste, and smell! Motor neuron: carry signals from spinal cord to muscles = movement (long axons)! Interneurons: carry info from sensory/motor/interneurons to nervous system or vice versa! Purkinjie cells: interneuron carries info from cerebellum to brain/spinal cord; bushy dendrites! Pyramidal cells: in cerebral cortex; triangle cell body!
