Brain
Gray matter of brain
outside
pia mater
the delicate innermost membrane enveloping the brain and spinal cord.
corpus callosum
the large band of neural fibers connecting the two brain hemispheres and carrying messages between them.
Olfactory tract
the path along which the olfactory receptors send their electrical messages to the brain.
Dura mater
thick, outermost layer of the meninges surrounding and protecting the brain and spinal cord
medulla oblongata
Part of the brainstem that controls vital life-sustaining functions such as heartbeat, breathing, blood pressure, and digestion.
cerebral peduncles
Superior to pons
Cranial nerves
12 pairs of nerves that carry messages to and from the brain -Look at trigeminal ganglion and it's branches.
Cerebellum
A large structure of the hindbrain that controls fine motor skills.
optic nerve
CN II
vestibuloacoustic nerve
CN III
oculomotor nerve
CN III (motor) controls eye movement; raises eye lids
Trochlear nerve
CN IV innervates the superior oblique muscle
Abducent n
CN VI
Vagus nerve
CN X provides parasympathetic innervation to most thoracic and abdominal viscera
accessory nerve
CN XI motor
hypoglossal nerve
CN XII motor nerve to tongue.
Massa intermedia
Gray matter in the midline of the third ventricle.
olfactory bulb
a brain structure located above the nasal cavity beneath the frontal lobes
Mammillary bodies
a protrusion of the bottom of the brain at the posterior end of the hypothalamus. -"brain boobies"
falx cerebelli
a small sickle shaped fold of dura mater, projecting forwards into the posterior cerebellar notch as well as projecting into the vallecula of the cerebellum between the two cerebellar hemispheres
Temporal lobe of brain
auditory
glossopharyngeal nerve
cn IX sensory - taste buds on posterior tongue, receptors in pharynx and carotid sinus; motor - muscles of pharynx and parotid gland BOTH
trigeminal nerve
cn V the main sensory nerve of the face and motor nerve for the muscles of mastication BOTH
Facial nerve
cn VII Innervates muscles of facial expression BOTH
Longitudinal fissure of brain
deep groove down the brain, separating left and right hemispheres
Tentorium cerebelli
extension of the dura mater that separates the cerebrum from the cerebellum
Folia
folds of the cerebellum
Frontal lobe of brain
initiates voluntary movement
white matter of brain
inside
falx cerebri
large, crescent-shaped fold of meningeal layer of dura mater that descends vertically in the longitudinal fissure between the cerebral hemispheres of the human brain.
Cerebrum
largest part of the brain
Parietal lobe of brain
perception, making sense of the world, arithmetic, spelling
inferior colliculi
protrusions on top of the midbrain; part of the auditory system. -Right below the superior colliculi.
superior colliculi
protrusions on top of the midbrain; part of the visual system
Transverse fissure of brain
separates cerebrum from cerebellum
Sulcus
shallow groove
gyrus (gyri)
sheet of nerve cells that produces a rounded ridge on the surface of the cerebral cortex.
Occipital lobe of brain
vision
arachnoid mater
weblike middle layer of the three meninges
arbor vitae
white matter of the cerebellum (tree of life)
