13 exam anatomy

Pineal body

appears to play a role in controlling the onset of puberty

Nuclei of cranial nerves 3 and 5 are located in the

midbrain

Sleep/wake cycle influenced by

midbrain and dicephalon

Gray matter on surface of the cerebrum is the

cortex

Central sulcus separates the

frontal and parietal lobes

Glossppharyngeal nerve

involved in the sense of taste

Fcaial and glossopharyngeal nerves are involved in the sensation of

tastes

Lateral fissure separates the ___ form the rest of the cerebrum

temporal lobe

Intermediate mass connects two portions of the

thalamus

Most sensory input that ascends through the spinal cord and brainstem projects to the

thalamus

Which brain portion is continous with the spinal cord

medulla oblongata

Whats true about brainstem

Damage is usually fatal

White matter of the cerebellum forms branching network known as

arbor vitae

Mamillary bodies

are involved in emotional responses to odors

Inferior coliculli

are involved with auditory pathways in CNS

Limbic system involves various neural connections between

cerebrum and diencephalon

Nerve tracts connect the two hemispheres are called

commisaral fibers

Tracts of white matter that connect right and left hemisphere are composed of

commissural fibers

Large C shaped mass of white matter consisting of nerve fivers that connect two cerebral hemispheres

corpus callosum

Pyramids of medulla contain

descending motor tracts

Nerve fibers that cross from one side f the nervous system to the other are said to

desscuate

The ____ is the part of the brain between the brainstem and the cerebrum

diencephalon

Most superficial meningeal layer is

dura mater

Facial expressions is regulated by the

facial nerve

InsulA

fifth lobe of brain

Eating disorder, intense thirst, varying temperature, may have dysfunction of the

hypothalamus

Nucleus that monitors blood temperature is located in the

hypothamlaus

Frontal lobe

important in voluntary motor function

Stalk that connects hypothalamus to the hypnosis (pituitary gland)

infundibulum

Smooth flowing movements are results of fine motor coordination in the

lateral cerebellar hemispheres

Patient with tramautic brain injury will have vomit as a result of the irritation of the

medulla oblongata

Small lesion in brainstem rsulting in rapid heart rate, intense vasoconstriction and elevated blood pressure would be located in the

medulla oblongata

Order from dicephalon down

midbrain, pons, medulla, spinal cord

Lesion in the cerebral peduncles might affect

movement

In the CNS, gray matter bodies are called

nuclei

Constriction of the pupuils of the eyes is controlled by the ______ nerve

occulomotor

Ptosis of left eye would be caused by damage to the

oculomotor nerve

CNS develop from flat mass of tissue called the neural

plate

Temporal lobe

plays role in memory

Two portions of brain involved in controlling respiration

pons and medulla oblongata

Occipital lobe

receoption and integration of visual input

Roman numerals assigned to each cranial nerve reflect

sequence from anterior to posterior in which they emerge from the brain

Cranial nerve function includes

somatic motor

Parietal lobe

somesthetic center

Cerebrospinal fluid fills the

subarachnoid space

Bird hits window, you duck, what is responsible for this action

superior colliculus

Diffucluty chewing results from damage to the

trigeminal nerve

Damage to what nerve causes death

vagus nerve

Cerebrospinal fluid is formed by tissue in the walls and roofs of the

ventricles of the brain
