Exercise 19: Gross Anatomy of the Brain and Cranial Nerves

HUMAN BRAIN- RIGHT LATERAL VIEW -(A - E)
A = POSTCENTRAL GYRUS
B = PARIETAL LOBE
C = PARIETO-OCCIPITAL SULCUS
D = OCCIPITAL LOBE
E = CEREBELLUM

HUMAN BRAIN- RIGHT LATERAL VIEW -(F - L)
F = PRECENTRAL GYRUS
G = CENTRAL SULCUS
H = FRONTAL LOBE
I = LATERAL SULCUS
J = TEMPORAL LOBE
K = PONS
L = MEDULLA
IN WHICH OF THE CEREBRAL LOBES ARE THE FOLLOWING FUNCTIONAL AREAS FOUND?

AUDITORY CORTEX
TEMPORAL LOBE
IN WHICH OF THE CEREBRAL LOBES ARE THE FOLLOWING FUNCTIONAL AREAS FOUND?

PRIMARY MOTOR CORTEX
FRONTAL LOBE
IN WHICH OF THE CEREBRAL LOBES ARE THE FOLLOWING FUNCTIONAL AREAS FOUND?

PRIMARY SENSORY CORTEX
PARIETAL LOBE
IN WHICH OF THE

GROUP OF STRUCTURES THAT DEVELOP FROM THE EMBRYONIC BRAIN ARE LISTED BELOW. DESIGNATE THE EMBRYONIC ORIGIN:

THE MEDULLA, PONS, AND CEREBELLUM
HINDBRAIN
EMBRYOLOGICALLY, THE BRAIN ARISES FROM THE ROSTRAL END OF A TUBELIKE STRUCTURE THAT QUICKLY BECOMES DIVIDED INTO THREE MAJOR REGIONS. GROUP OF STRUCTURES THAT DEVELOP FROM THE EMBRYONIC BRAIN ARE LISTED BELOW. DESIGNATE THE EMBRYONIC ORIGIN:

THE CEREBRAL HEMISPHERES
FOREBRAIN
WHAT IS THE FUNCTION OF THE BASAL GANGLIA?
CONTROLLING VOLUNTARY MOVEMENTS AND ESTABLISHING POSTURES.
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).
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.
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,
