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
