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