arbor vitae?
is the white matter of the cerebellum that is an extension of the superior and inferior peduncles
tuber cinereum
manhole like structure visible after removal of infindibulum / sella turcica
Central nervous system
neurotransmitter bundles are called tracts and are myelinated with oligodendrocytes. also known as nucleus and nuclei
peripheral nervous system
bundle of neurotransmitter called nerves and are myelinated by schwann cells. also known as gangli and ganglion
infindibulum
tube like structure connecting the hypothalamus and posterior pituitary (attached to sella turcica) that releases vasopressin and oxytocin
superior oliva
sound localization; both ears receive input, but more right noise stimuli will cause left auditory receiver to be engaged first then back to temporal lobe. ALSO we receive sound first subconsciously before we become aware of “hearing it”
uncus
olfaction to memory; rostral end of limbic lobe
pons
regulates sleep wake cycle (circadian rhythm) ALSO deficit is REM behavior disorder –> acting our your dreams
insula
where three sulci meet and deals with visceral processing (knowing what the guts are doing)
trapezoid bodies
auditory contralateral projection
cerebral peduncles
connector of old brain with new brain; damage causes coma like state
primary somatosensory cortex
caudal to central sulcus and mediates senses (humunculus)
temporal lobe
auditory processing / language comprehension.
inferior peduncles
sends and receives signals from the vestibular system. Zone Specific! medial zone:
meninge; dura mater
is the outermost of the three layers making up the meninges. It is a thick, durable membrane, and is closest to the skull. It is responsible for keeping in the cerebrospinal fluid, and for surrounding and supporting the dural venous sinuses that carry blood from the brain to the heart
meninge; arachnoid mater
is the middle layer of the meninges, and is named from its spider web-like appearance. It provides a cushioning for the central nervous system
meninge; pia matter
is the innermost layer of the meninges. It envelopes and firmly attaches to the surface of the brain and spinal cord. The pia mater contains blood vessels and capillaries that are responsible for nourishing the brain
falx cerebri
a strong arched fold of dura mater that descends vertically in the longitudinal fissure between the cerebral hemispheres
bregma
the point or area of the skull where the sagittal and coronal sutures joining the parietal and frontal bones come together.
dorsolateral prefrontal cortex
working memory
folia
grey matter functions are same as vitae and are zone specific
brocas area
frontal temporal lobe; language production and when damaged causes aphasia; however even when damaged patients can sing to be understood
