Ok, so you’re using my notecards which is great. I am glad I could help you out cause I wish I had someone to help me out when I took this course. I know Anatomy is super hard.
I only ask that if you find these notecards helpful, you join Easy Notecards and create at least one notecard set to help others out. It can be for any subject or class. Thanks and don’t forget to rate my helpfulness!

32
WHAT IS THE FUNCTION OF THE BASAL GANGLIA?
CONTROLLING 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 CAPSULE PASS THROUGH THE DIENCEPHALON AND BASAL NUCLEI, GIVES THEM STRIPED APPEARANCE. THEREFORE, THEY ARE RELATED AND REFFERED TO AS CORPUS STRIATUM (STRIPED BODY).
34
A BRAIN HEMORRHAGE WITHIN THE REGION OF THE RIGHT INTERNAL CAPSULE RESULTS IN PARALYSIS OF THE LEFT SIDE OF THE BODY. EXPLAIN WHY THE LEFT SIDE (RATHER THEN THE RIGHT SIDE) IS AFFECTED.
FIBERS CROSS TO THE OPPOSITE SIDE OF THE BRAIN THROUGH THE MEDULLA OBLONGATA.
35
EXPLAIN WHY TRAUMA TO THE BASE OF THE BRAIN IS OFTEN MUCH MORE DANGEROUS THEN TRAUMA TO THE FRONTAL LOBE. (HINT: THINK ABOUT THE RELATIVE FUNCTIONING OF THE CEREBRAL HEMISPHERES AND THE BRAIN STEM STRUCTURES. WHICH CONTAIN CENTERS MORE VITAL TO LIFE?)
THE BASE 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.
36

DESCRIBE WHAT RESULTS (IN TERMS OF BEHAVIOR) CAN BE ANTICIPATED IN SUCH EXPERIMENTS. "SPLIT BRAIN"
PERSON WILL BE UNABLE TO VOCALLY NAME WHAT THEY ARE/HAVE SEEN. A PERSON'S MEMORY IS GENERALLY LOWER THEN NORMAL. CONTROL AND MEMORY CAN BE AFFECTED BY THE SPLIT BRAIN EXAMPLES: MATHEMATICS AND SPEECH CAN BE AFFECTED, LOSS OF DREAMS, CAN BECOME MUTE, AND CANT CONTROL LEFT SIDE OF BODY.

Extremely helpful for Anatomy/Physiology Lab.

Lovelykamfwa000 10 months ago

nice one!!!!!!!!!!

mcclyburn50 10 months ago

First of all, thank you for all your help. Second, two corrections: #56 should be IX glossopharyngeal because it is for taste and sensation by internal organs and secreting saliva Also,#58 I believe should be X vagus.

cdwike 10 months ago

Thank you for your note cards! I make study guides on quizlet all of the time because it is really helpful, so maybe look me up on there. carrie_wike . Thanks again!

aliwon123 2 years ago

for your notecard #31, the answer should be midbrain not forebrain right?

THE CEREBRAL HEMISPHERES
FOREBRAIN

aliwon123 2 years ago

Thank you so much for your note card, it makes it easier for me to know whether or not i got all my answer right when i work on the exercise myself.
