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