Introduction Action Potential in the Nervous System: Transcript
Conveys information over long distances Cytosol has negative charge relative to extracellular space Neural code frequency and pattern Action potential Spike Nerve impulse Discharge Properties of the Action Potential. Functions of the Nervous System. Sensory input – gathering information. To monitor changes occurring inside and outside the body. Changes = stimuli. Integration. To process and interpret sensory input and decide if action is needed. The Brain and Behavior:. Divisions of the Nervous System. Neurons – Structure and Communication. Structures and Functions of the Brain. Brain Damage, Plasticity, and Repair. Nervous System. Central Nervous . A). Neurology. – study of nervous system. B) . neuron. s. – conducting cells of the nervous system, normally do not divide (non-mitotic). C) . neuroglia. – supporting cells of the nervous system, mitotic, numerous. Peripheral Nervous System.

Neurons and . neuroglia. Types. Nerve signal and transmission. Central Nervous System. Brain and spinal cord. 1. Two main divisions. a. . Central Nervous System . (CNS) – consists of brain and spinal cord. b. . Peripheral Nervous System . (PNS) – includes nerves extending from . brain and . spinal . cord . Brain. Spinal Cord. (also includes 4 chambers in brain called ventricles). Brain. 1) Cerebral Hemispheres. 2) Diencephalon. 3. ) Brain Stem. 4) Cerebellum. 1) Cerebral Hemispheres. Covered by ridges = . A. Central Nervous System (CNS). 1. . Functions . A) . Acts . as command center. B) . Interprets . sensory information and dictates response based on past experience, . reflexes, . and current body conditions. Human nervous system two major parts: central nervous system and peripheral nervous system. Nervous System Organization. Brain. Spinal cord. Central Nervous System. Nervous System Organization. All neurons outside the CNS. Today. ’. s lecture. -What are nervous systems for. -A diversity of nervous system organizations. -Information processing. -A review of neuron structure. -Resting Potential. -Action potentials. -Synapses and neurotransmitters. AUTONOMIC NERVOUS SYSTEM. Two major subdivision. Parasympathetic . cranio. -sacral outflow. Sympathetic . . thoraco. -lumbar out flow. Responsible for the visceral control. Sometimes referred to as vegetative control.
