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