brain stem
this nerve tract connects the pons and cerebellum
middle cerebellar penducles
this cranial nerve is purely sensory and has two distinct branches for equilibrium and hearing
CNVIII vestibulocochlear nerve
coordination and fine tuning muscle movements to ensure they are smooth is this structures primary function
cerebellum
this ventricle is located within the brain stem
fourth ventricle
this large gray matter mass acts as the principle relay station for all concious sensory information except for olfaction
the thalamus
this structure within the mid-brain houses dopamine producing neurons, and its degeneration is directly linked with parkinsons disease
substantia nigra
CN V trigeminal
this lobe is primarily responsible for storing visual memories and processing visual information
this fringe like vascular process of pia matter contains the specialized tissue within the brains ventricles that produces CSF
choroid plexus
This anteroinferior region of the diencephalon monitors nutrient levels to regulate hunger and also signals the pineal gland to secrete melatonin to regulate sleep-wake rhythms.
hypothalamus
this center in the medulla oblongata is responsible for contraction and relaxation of blood vessels thus regulating blood pressure
vasomotor center
this cranial nerve is a mixed nerve responsible for taste from the anterior tongue, controlling muscles of facial expression, and stimulating tear and salivary glands
CNVII facial nerve
this dura fold located within the longitudinal fissure serves as a partition between the two cerebral hemispheres
Falx cerebri
this structural feature of brain capillaries primarily forms the blood-brain barrier
tight junctions between capillary endothelial cells
this nucleus acts as the bodys master clock and directs the pineal gland to regulate circadian rhythm
suprachiasmatic nucleus
This most inferior portion of the brainstem contains the Cardiovascular Center, which regulates heart output and blood vessel diameter, and also houses the Medullary Respiratory Center, which communicates with the pons to adjust breathing rate.
medulla oblongata
a patient unable to voluntarily move their eyes, raise thier eyelids, or contract their pupils in response to bright light has an issue with this cranial nerve
CNIII oculomotor nerve
this gyrus contains the primary motor cortex responsible for voluntary movement
precentral gyrus
the pathway for CSF flow from the lateral ventricles to the fourth ventricle follows this sequence
through interventricular foramens, into the third ventricle, through the cerebral aqueduct
these specific thalamic nuclei are primarily responsible for conveying motor information from the cerebellum and globus pallidus to the precentral motor cortex
motor nuclei
This most superior portion of the brainstem is characterized by the Substantia nigra, a dopamine-producing cell cluster whose degeneration leads to Parkinson’s disease, and the Tectum, which contains the colliculi controlling visual tracking and auditory reflexes.
the midbrain
A patient is unable to abduct their left eye (move it laterally). This deficit points to a lesion in this cranial nerve
CNVI abducens nerve
this functional brain region, typically located in the left hemisphere, is crucial for comprehending language
Wernicke area
these deep gray matter masses, also known as subcortical nuclei, are involved in producing the patterns and rhythms of walking movements and adjusting muscle tone
caudate nucleus and lentiform nucleus
This large, oval mass of gray matter within the diencephalon filters out distracting background sensory signals, receives input from all conscious senses except olfaction, and uses its motor nuclei to convey information from the globus pallidus to the precentral motor cortex.
