Central Nervous System Flashcards
composed of the brian and spinal chord
Central Nervous System
located within the cortex of the brain
Gray Matter
composed of nerve cell bodies
located beneath the cortex
White matter
composed of tracks of myelinated nerve fibers
The main superior component of the brain in charge of memory and reason;
Cerebrum
elevations on the cortical surface of the brain
cerebral gyrus
mountains
groves betreen the cerebral gyri
cerebral sulcus
valleys
when you sulk, you are down
right and left halfs of the cerebrum
cerebral hemispheres
comprises most of the anterior half of the cerebrum
Frontal Lobe
in charge of personality and contraction of skeletal muscle
the top, posterior portion of the cerebrum
Pariatal Lobe
associated with speech, emotions, and visual interpetations
the lateral portion of the cerebrum
temproal Lobe
associateed with memory memory, hearing, and visual activities
found deep beneath the lateral sulcus
Insula lobe
Inside
associated with memory and interpetation of taste
most posterior portion of the cerebrum
Occipital Lobe
associated with interpetation of visual images and eye movement
deep grove that seperates the right and left hemisheres, follows the sagital suture line
Longitudinal Fissure
devides brain in a trasverse section; follows the squames suture
lateral sulcus
separates the frontal from the temporal lobes
divides the brain in a coronal section
Central Sulcus
separates the frontal from the patiatal lobes
farther back than you think it shoud be
can only be seen from the medial side of a saggital cut
parietooccipital sulcus
separates parietal and occipital lobes
a commissure connecting the two cerebral hemispheres, unifying awareness between them
corpus callosum
anterior portion of the corpus callosum
genu
genusis sit in the front
posterior portion of the corpus callosum
splenium
but it’s splendid to sit in the back
paired organ lateral and superior to third ventrical of the diencephalon
Thalamus
recives ans sends impulses to precise loatations within the cerebral lobes for interpretation
a small midline commissure connecting the right and left thalumus
interthalmic adhesion
(intermediate mass)
forms posterior root of diencephalon and covers the third ventrical, composed of penial gland and habenulear nucleus
epithalamus
located within the floor of the diencephalon or third ventrical,
Hypothalamus
provides control over the autonomic nervous sysyem and endocine system
beak of the bird
the stalk that connets the pituritaly gland to the hypothalamus
Infundibulum
the stem of the cherry
a small endocrine gland projecting inferiorly from hypothalumus and situated in the sella turcica; master gland
Pituitary gland
the cherry
two nodes loctated inferiorly to the third ventrical and superior and anterior to the pons
Mammiliary Bodies
function as a relay center for olfactory sensations
patriks testicles
a small hormone secreating gland in the posterior portion of the epithalumus, located superior to the corporal quadrigemina
pineal gland
located in the medial temporal lobe underneath the cortical surface, makes up part of the limbic system, plays a role in spatial navigation and long-term memory
hippocampus
consists of mid-brain; pons and medulla oblongota
brain stem
