cerebral hemispheres, diencephalon, brain stem, cerebellum

how is the gray matter organized?

how is the white matter organized?

lateral, third, cerebral aqueduct, fourth ventricle

what part of the brain has expansions of the brain's central cavity, filled with cerebrospinal fluid, lined with ependymal cells, continuous with each other, continuous with the central canal of the spinal cord?

which part of the brain has functions like automatic behaviors necessary for survival, passageway for all fiber tracts between cerebrum and spinal cord, involved with intervention of face and head?

function)respiration and circulation

vestibulocochlear(VIII), glossopharyngeal(IX), vagus(X), accessory(XI), hypoglossal(XIII)

(function)carrying voluntary motor output from cerebrum to spinal cord

(function)controls voluntary movement of the opposite side of the body

(function) is carry information on equilibrium from vestibular nuclei and proprioception from the spinal cord to the cerebellum?

(function)regulation of breathing

trigeminal (V), abducens (VI), facial nerve(VII)

(location)ventral to the reticular formation are the thick pyramidal motor tracts descending from the cerebral cortex. interspersed among the fibers of these tracts.

(components)Pyramids, Decussation of the pyramids,Inferior cerebellar peduncles, cranial nerves

(components)pontine nuclei, middle cerebellar peduncles, cranial nerves

which part of the pons functions to connect portion of the cerebral cortex with the cerebellum and through this pathway involves the coordination of voluntary movements?

which part of the pons has the function to carry info from cerebral cortex and pontine nuclei to cerebellum?

which part of the midbrain has the function of fight/flight reaction; mediates response to visceral pain?

which part of the midbrain has the function to conduct nerve impulses between higher and lower brain centers?

which part of the midbrain has the function to carry instructions from cerebellum to cerebral cortex?

which part of the midbrain has the function of nuclei that act in visual reflexes?

which part of the midbrain has a function of nuclei that act in reflexive response to sound?

(components)periaqueductal gray matter, cerebral peduncles, superior cerebral peduncles, corpora quadrigemina, superior and inferior colliculi

who functions as smoothes/coordinates body movements, help maintain equilibrium

which part of the cerebellum is located deeply situated gray matter?

this part of the brain is located in center core of the forebrain surrounded by cerebral hemispheres

what is the diencephalon composed of?

the functions of this part of the brain relay stations for incoming sensory message, every party of brain communication w/ cerebral cortex relays signals through thalamic nuclei

the nuclei organize & the function of the neucli amplify or tone down signals

the functions of this part control: emotional response, behavior, and endocrine system.

83% total brain mass

this part has dozen nuclei & the functions of the nuclei are visceral control center of the body

What are the Brodmann areas?

reveal areas of maximum blood flow to the brain, which are presumed to be areas participating in mental activity being performed

what are the general locations for the conscious awareness sensory areas?

insula lobe

(FUNCTION AREA)receives sensory input like pain, pressure, hunger

interface of visual, auditory and somatosensory association area

(FUNCTION AREA)awareness of spatial location of body-"body sense" & Related to language comprehension and speech

frontal lobe

(FUNCTION AREA)receives info from posterior association area, integrates info. with past experience, initiates motor movements

medial sides of frontal lobe

(FUNCTION AREA)memory, emotions, sensory/motor behaviors, formation of memory, processes emotions

posterior frontal lobe

(function CORTEX)control motor function

large neurons of primary motor cortex

the two hemispheres control opposite sides of the body

(location)different areas of the cerebral cortex
