Nervous System & Psychological Disorders review

the network of structures that coordinates, and control all functions of the body nervous system
create sensations, produce thoughts and memory and make decisions based on sensory input integrative functions
is composed of the brain and the spinal cord central nervous system
composed of two types of cell: neurons and neuroglia nervous system
carries impulses away from the cell body axon
transmit impulses to the cell dendrites
axons are surrounded by a white lipid covering called myelin sheath
the region of communication between one neuron and another is called synapse
a chemical that transmits a nervous impulse that either inhibits or enhances a reaction neuro/transmitter
concerning both nerves and muscles neuro/musclu/ar
the area of contacht between a neuron and adjoining skeletal muscle neuromuscluar
an automatic, involuntary response to some change, either inside or outside the body is reflex
brain and spinal cord are protected by three membranes called meninges and circulating cerebrospinal fluid
pertaining to meninges meningeal
below the dura mater subdural
the largest and uppermost portion of te brain cerebrum

two nerves bound together by a common sheath of connective tissue is sciatic nerve

portion of the nervous system that is outside the central nervous system periphearl nervous system
systems that are divisions of the autonomic nervous system sympathetic and parasympathetic
activation of the sympathetic division causes a series of physilogic reponses called fthe fight-or-flight response
receptors that are stimulated by chemcial stimuli are chemoreceptors
senstive to mechanical changes in touch or pressure are widely distributed in the skin mechano/receptors
located immediately under teh skin and are widely distributed throughout the body thermo/receptors
detect changes in tempearture thermorecptors

sensitivity of the eyes to light photophobia
absence of speech dys/phasia
difficult, poorly articulated speech, usually caused by damage to a central of periphearl motor nerve is dys/arthria
any disease involving the spinal cord and brain encephalo/myelo/pathy
accumulatin of blood between the dura mater and the archnoid is subdural hematoma
an abnormal localixed dilation of a cerebral artery cerebral aneursym
caused by the rupture of a cerebral artery hemorrhagic strokes
caused by a cerbral embolus embolic stroke
caused by plaque deposits that build up on thinterior of a cerbral artery thrombotic strokes
