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