Dura mater, archnoid, Pia mater
discribe the layers of the meninges?
dura mater- tough outter layer
arachnoid- middler layer
pia mater- inner most layer that tightly adhears to the brain and spinal cord
which lobe of the brain coordinates voluntary movement?
frontal lobe
cranial nerves and spinal nerves are part of the ——- nervous system
peripherial
what are the meninges?
membranes that line the skull and vertebral canal and protects brain and spinal cord
what is the neron?
nerve cell
which nervous system disorder causes a sever head ache, nauses, and vomiting, and is diagnosed with a lumbar puncture?
meningitis
what portion of the brain stem controls heart beat and resprtaion?
medulla
After someone has experianced a stressful event, what part of the nervous system brings breathing and pulse rate back to normal and causes fatigue?
autonomic nervous system- parasympathetic
which nervous system division woukd cause tachycardia and dry mouth following a stressful of exciting event?
The autonomic nervous system- sympathetic
true or false: impulses travel form one neron to another by way of the myelin sheath. if this is false, what is the correct answer?
synapse
the cns is made up of which organs/ structures ?
brain and spinal cord
which type of neurons carry messages from the brain and spinal cordro muscles and glands?
moter neurons
what part of the nervouis system would you be assessing with a pellar tendon reflex?
spinal nerves
which nervous system disorder is caused by an insect bite and causes a headache + stiff neck?
west nile virus
wat part of the nevous sysytem would be damaged by falling from a horse resulting in tingiling +burning in the legs?
peripherial nervous system
what is phantom pain?

what are the components of the autonomic nervous system?
parasympathetic and sympathetic
what changes in the body does the sympathetic nervouse system produce?
the body prepares to fight, heart rate increases, mouth becomes dry, pupils and bronchi dilate, sweaty palms
what changess in the body does the parasympathetic nervous sysytem produce?
it counteracts sympathetic system
what does parapeligia mean?
paralysis of legs and lower body
what part of the brain controls planning, imformation recall, and decision making?
cerebrum
what substance associated with the spine could leak with a spinal cord injury?
cerebrospinal fluid
what functions does the hypothalamus control?
autonomic nervous control, cardiovascular control, temperature control, appetite control, and sleep control
where is the cerebellum located?
behind the pons and below the cerebrum
