PSY 106 Chapter Notes - Chapter 3: Autonomic Nervous System, Cranial Nerves, Peripheral Nervous System
Document Summary
Ch3 - the anatomy of the nervous system. Division of the nervous system: vertebrate nervous system, 1. Dura mater - the outer meninx, the tough membrane: 2. Subarachnoid space - beneath the arachnoid which contains many large blood vessels and cerebrospinal fluid: 4. In the rest of the body, the cells that compose the walls of blood vessels are loosely packed most molecules pass readily through them into surrounding tissue but. Interneurons - neurons with short axons or no axons: function is to integrate the neural activity within a single brain structure, not to conduct signals from one structure to another. Two kinds of gross neural structures in the nervous system: clusters of cell bodies - nuclei (cns), ganglia (pns, bundles of axons - tracts (cns), nerves (pns) Inferior - bottom of the head: superior - top of the primate head, proximal - close (closer to the cns, distal - far (further from the cns)
