Ok, then you're using my notecards which is slap-up. I am glad I could assist y'all out cause I wish I had someone to assist me out when I took this course. I know Anatomy is super hard.
I only ask that if you find these notecards helpful, you bring together Piece of cake Notecards and create at least one notecard set up to aid others out. It can be for any bailiwick or class. Thanks and don't forget to charge per unit my helpfulness!

EMBRYOLOGICALLY, THE BRAIN ARISES FROM THE ROSTRAL Terminate OF A TUBELIKE Structure THAT Chop-chop BECOMES DIVIDED INTO THREE MAJOR REGIONS. Grouping OF STRUCTURES THAT DEVELOP FROM THE EMBRYONIC Encephalon ARE LISTED BELOW. DESIGNATE THE EMBRYONIC ORIGIN:
THE DIENCEPHALON, INCLUDING THE THALAMUS, OPTIC CHIASMA, AND HYPOTHALAMUS
30
EMBRYOLOGICALLY, THE BRAIN ARISES FROM THE ROSTRAL END OF A TUBELIKE STRUCTURE THAT QUICKLY BECOMES DIVIDED INTO 3 MAJOR REGIONS. Grouping OF STRUCTURES THAT DEVELOP FROM THE EMBRYONIC Encephalon ARE LISTED Below. DESIGNATE THE EMBRYONIC ORIGIN:
THE MEDULLA, PONS, AND CEREBELLUM
31
EMBRYOLOGICALLY, THE Encephalon ARISES FROM THE ROSTRAL Cease OF A TUBELIKE STRUCTURE THAT Chop-chop BECOMES DIVIDED INTO 3 MAJOR REGIONS. GROUP OF STRUCTURES THAT DEVELOP FROM THE EMBRYONIC BRAIN ARE LISTED Below. DESIGNATE THE EMBRYONIC ORIGIN:

32
WHAT IS THE FUNCTION OF THE BASAL GANGLIA?
Decision-making VOLUNTARY MOVEMENTS AND ESTABLISHING POSTURES.
33
WHAT IS THE CORPUS STRIATUM, AND HOW IS IT RELATED TO THE FIBERS OF THE INTERNAL CAPSULE?
FIBERS OF THE INTERNAL Sheathing PASS THROUGH THE DIENCEPHALON AND BASAL NUCLEI, GIVES THEM STRIPED Advent. THEREFORE, THEY ARE RELATED AND REFFERED TO Every bit CORPUS STRIATUM (STRIPED Torso).
34
A BRAIN HEMORRHAGE Within THE REGION OF THE RIGHT INTERNAL Capsule RESULTS IN PARALYSIS OF THE LEFT SIDE OF THE Torso. Explicate WHY THE LEFT SIDE (RATHER THEN THE Right SIDE) IS Affected.
FIBERS Cantankerous TO THE Opposite SIDE OF THE BRAIN THROUGH THE MEDULLA OBLONGATA.
35
Explicate WHY TRAUMA TO THE Base of operations OF THE Encephalon IS OFTEN MUCH More DANGEROUS THEN TRAUMA TO THE FRONTAL LOBE. (HINT: Retrieve Most THE RELATIVE FUNCTIONING OF THE Cerebral HEMISPHERES AND THE Encephalon STEM STRUCTURES. WHICH Comprise CENTERS MORE VITAL TO LIFE?)
THE Base of operations OF THE BRAIN IS More DANGEROUS THEN TRAUMA TO FRONTAL LOBES Because IT CONTAINS THE CENTERS MORE VITAL TO LIFE SUCH AS, RESPIRATORY, CARDIAC, AND VASOMOTOR CENTERS.

Depict WHAT RESULTS (IN TERMS OF BEHAVIOR) Tin Exist Anticipated IN SUCH EXPERIMENTS. "Carve up Brain"
PERSON WILL Exist UNABLE TO VOCALLY Name WHAT THEY ARE/Accept SEEN. A PERSON'S MEMORY IS More often than not LOWER And so NORMAL. CONTROL AND MEMORY CAN Be AFFECTED By THE Dissever BRAIN EXAMPLES: MATHEMATICS AND SPEECH Tin Exist AFFECTED, LOSS OF DREAMS, CAN BECOME MUTE, AND Deceit Command LEFT SIDE OF Body.
