Document Summary
Ch 12: nervous tissue: describe the structures and organization of the nervous system, central - brain neurons. Sensory (afferent) neurons transport sensory info from skin, muscles, joints, organs to cns. Motor (efferent) neurons send motor nerve impulses to muscles and glands. Interneurons (association) connect sensory to motor neurons, 90% of neurons in the body. Produces action potentials (electrical excitability) support tissue. Multipolar, bipolar, unipolar nuclei: peripheral cranial nerves spinal nerves support tissue ganglia, somatic. Neurons from cutaneous and special sensory receptors to the cns. Motor neurons to skeletal muscle tissue afferent. Sensory info from skin to cns efferent. Connect sensory to motor neurons: autonomic. Sensory neurons from visceral organs to cns. Motor neurons to smooth and cardiac muscle and glands sympathetic. Involuntary sensory and motor neurons control gi tract. Neurons function independently of ans and cns: distinguish the structural characteristics of gray and white matter.
