Perfectly

what are ependymal cells?

line the ventricular system of the brain and play a key role in production of cerebrospinal fluid

what are microglia

in the CNS remove damed neurons

what part of the spinal cord is the integrating center between sensory and motor nerve cells in?

the grey matter of spinal cord

what is the dorsal root

transmits sensory information forming afferant sensory root of a spinal nerve

what is the ventral root

the motor root of a spinal nerve which carries motor info from the spinal cord to the rest of the body

where is the cerebral spinal fluid made?

specialized ependymal cells in the choroid plexuses of the ventricles of the brain

what menigx clings tightly to the brain and spinal cord?

pia mater

what does the blockage of the flow of CSF result in?

hydrocephaly

whats the arachnoid mater?

Connected to the dura mater on the side closest to the CNS middle layer that part of the suspension system that helps protect the brain and spinal cord from sudden impact

what is subarachnoid space?

pace between the arachnoid and pia mater, which is filled with cerebrospinal fluid.

what part of the brain is involved in body tempt control?

hypothalamus- linked to the endocrine system via the pitutitary gland

what part of the brain is involved in habitual or automatic actions in sequence like walking?

cerebellum- balance movement

cerebral cortex

gray matter outside of brain

function of the temporal lobe?

revolves around hearing and selective listening, sensory information sound speech undering spoken language

function of medulla?

controls certain ANS responses such as heart rate, breathing, swallowing and vomiting.

what is the function of the thalamus?

relay station between the spinal cord and cerebral cortex. filters and sorts

what part of the brain inhibits unwanted movements and what is its NT?

basil ganglia which NT is Dopamine

what is NOT part of the brain stem?

cerebellum

what part of the brain is associated with memory?

the limbic system. the amygdala amy is emotional

most conscious sensations are interpreted by what?

the cerebral cortex

pons function?

controls breathing, communication between diff parts of the brain, located in brain stem

what is the function of the reticular activating system?

it helps keep you awake. | highways goes down when you sleep goes down to thalamus

what brain waves are generated by the cortex when you are focusing, thinking, or concentrating?

beta

brain wave when are frustrated?

theta

brain wave when you are sleeping?

delta

brain wave when you are happy or relaxed

alpha

true or false. a gyrus is a shallow groove in the brain surface?

false. salcus

t or f the broca region is found in the occipital/partial area of the brain?

false. werinicke area responsible for the comprehesion of the speech

broca area function?

production of speech motor ability to talk

all post ganglionic neurons bear these receptors

nicotinic-ach-activates on/off
