Document Summary
Psyb64 - chapter 3: cells of the nervous system. Neuron is specialized to carry out the functions of info processing and communication. The glia serve a variety of support functions for neurons. Many of the organelles are found in the soma or cell body. Neurons are different from other cells in that they have axons and dendrites which are used to communicate with other cells. The neural cytoskeleton: the cytoskeleton provides structural support to the neuron, 3 types of filaments make up the skeleton . Neurofilaments most common in the neuron; run parallel to the length of the axon and provide structural support. Microfilaments smallest; may participate in changing he shape and length of the structures during development since they are located in the branches of the neurons. Ranvier: myelin allows human axons to be smaller in diameter without sacrificing transmission speed and space is saved.
