Cerebrum Flashcards
Provides the sensory, motor, and integrative functions of consciousness.
Cerebrum
Consists of the thalamus, hypothalamus, pineal gland, and mammillary bodies.
Diencephalon
Consist of the pons, medulla oblongata, and midbrain.
Brainstem
Helps control balance, posture, and fine motor coordination by comparing intention with motor performance.
Cerebellum
The grayfish-white, semi-transparent rough membrane encapsulating the brain
Dura mater
The middle meningeal membrane
Arachnoid mater
The innermost transparent membrane that adheres to the convolutions of the brain
Pia mater
The right and left cerebral hemispheres are separated by the _____ along a midsagittal line.
Longitudinal fissure
The surface of the cerebrum contains deep grooves
fissures
Shallow grooves
Sulci
Elevations _____ project between sulci.
Gyri
The wrinkling effect of sulci and gyri drastically increases the between sulci.
Cerebral cortex
The part of the cerebral hemisphere anterior to the cruciate fissure.
Frontal lobe
the area posterior to the central sulcus
Parietal lobe
The line of separation from the more posteriorly placed ______ is difficult to see in the sheep brain
Occipital Lobe
The sheep brain is portly developed and difficult to distinguish from the parietal lobe.
Temporal lobe
The deep within the lateral fissure between the temporal and frontal lobes.
Insula
Lie in the superior to the cribriform plate of the ethmoid bone and receive fibers from neurons in the olfactory in the epithelia lining the nasal cavities.
Olfactory bulbs
the flat ______ lie on the ventral surface of the brain and project to the olfactory portions of the brain.
Olfactory tracts
Where the nerve fibers from the medial aspect of each eye cross over to the opposite side.
Optic chiasma
Ventral side of the brain (Pea-sized)
Pituitary gland
A thin stalk that connects the body of the pituitary to the hypothalamus.
Infundibulum
Locate the small but distinct protuberance that is immediately posterior to the infundibulum.
Mammillary body
Place the brain on its ventral surface. The _____ is separated from the cerebrum by the _____.
cerebellum, Transverse fissures
The human cerebellum consist of the two large, lateral hemispheres connected by a “worm-like” cross the bridges.
Vermis
The outline if the white matter seen midsagittally resembles tree branches
Arbor vitae
Continue to separate the cerebellum from the medulla until the tela choriodea ruptures. The internal space revealed by this maneuver is the fourth ventricle. looking into the fourth, you may see some dark spongy tufts. These are pieces of ____, the primary source of CSF
Choroid plexus
The ____ contains three vital reflex centers that help regulate heart rate, blood pressure, and respiratory rate.
Medulla Oblongata
The ___ contain tracts involved in regulating skeletal muscle activity.
Pyramids
Lies directly directly anterior to the medulla; it acts as a relay station for cortical fibers projecting to the the cerebellum.
Pons
Consist of Superior colliculi and inferior colliculi
Corpora quadrigemina
The ____ is immediately anterior to the superior colliculi.
Pineal gland
The ____ is a large oval structure that comprises about 80% of the diencephalon. It is the located superior to the midbrain and consists of gray matter covered by a layer of white matter.
Thalamus
The mammillary body on the sheep brain marks the posterior limit of the ____. The anterior border of the ______ is marked by the optic chiasma.
Hypothalumus
A large curved band of fibers that comprises the primary commissure between the cerebral hemispheres.
Corpus callosum
Formed by secretion from tufts of fenestrated capillaries, called choroid plexuses, found in each ventricle.
