Function/DefinitionNervous System PartWhere in the Nervous System
Gaps in myelin sheath along an axon
Pain, Temperature, Meissner corpuscle (touch/texture), Pacinian corpuscle (pressure)
P: Impulse moves toward cell body (hopping over myelin in PNS)
Receives and interprets information from sensory receptors
Subdivision that deals with involuntary control of body
Naming visual imput and understanding language
Specialized rough ER in neuron
Rapid, predicatble and involuntary response to stimuli
Breathing Control
Collects, integrates, and evaluates smell data
Involuntary coordination of body movements; balance; cauliflower-shaped
Houses pineal body and choroid plexus to make cerebrospinal fluid
Watery cushion to protect brain, in subarachnoid space, ventricles, and central canal of spinal cord
Keeps harmful substances from brain through Blood
Neuromuscular disorder in which voluntary muscles are poorly controlled
Integrates and evalutates hearing data
Conducts impulses toward cell body
I: Na+ ions into neuron
Understanding language *similar to another area*
Ridges in brain
Failure of cerebrum to form
Heart rate; blood pressure; breathing; swallowing; vomiting; not crocodiles
'Rest and Digest'
Creates new memories; spacial memory, navigation
Spiderlike phagocyte; disposes of debris
Function/DefinitionNervous System PartWhere in the Nervous System
The emotional brain
'Fight or Flight'
R: charge on membrane returns to normal when K+ moves out of neuron
Division that carries info TO body tissues/organs from CNS
Coordinates emotional response to pain and regulates rage and aggresion
Collects hearing data
Conducts impulses away from cell body
produces myelin sheath around CNS nerve fibers
Grooves in brain
Consists of the brain and spinal cord
Sends impulses to skeletal muscles
R: Na+ and K+ change places VIA Sodium-Potassium pumps
Star-shaped; braces neurons and controls chemical environment of brain
Plans carrying out complex motor sequences
3 connective tissue membranes that cover brain and spinal cord
Cytoskeleton, maintains neuron shape
Forgetfulness, irritability, difficulty concentrating as aging occurs
Fluid buildup on the brain due to failure of cerebrospinal fluid drainage
Connects the Left and Right hemispheres of Cerebrum
Lines cavities of brain and spinal cord; circulates cerebrospinal fluid
Consists mostly of neuron cell bodies
Junction between two neurons
Collects, integrates, and evaluates taste data
Regulates body temp, H2O balance; part of limbic system
Digestive organ control, consciousness and sleep cyles
Function/DefinitionNervous System PartWhere in the Nervous System
Helps you physically say what you want to say
Connects sensory and motor neurons
Collects sight data
Integrates and evaluates sight data
D: change in polarity of cell membrane
Division that carries info FROM body sense organs to CNS
Consists of cranial and spinal nerves
Gap between adjacent neurons
Forms myelin sheath in PNS
Golgi Tendon Organ, Muscle spindle, detecting stretch/tension in muscle
Protects neuron cell bodies
Improper formation of the vertebra, leading to a pinched spinal cord
Nerve Impulse
Substance that continues a nerve impulse from an axon to a dendrite
Planning action and movement, abstract thought, emotion and judgment
Relay station for sensory impulses and sends them to correct cortex
Inflammation of meninges
Subdivision that deals with voluntary/conscious control of body
Reflex centers for vision and hearing
Degenerative disorder of the CNS that impairs the sufferer's motor skills, cognitive processes (pill-rolling tremors)
Fiber tracts such as Corpus Callosum
Direct route from a sensory to motor neuron via an interneuron
Result of excessive alcohol consumption during pregnancy
