capacity
B. Primary visual area
3.
Cerebrum
C.
4.
Cerebral Cortex
D. Bridge connecting various parts of the brain
5.
Cerebellum
E.
Relay station for all sensory information except smell
6.
Frontal Lobe
F.
Helps to maintain homeostasis (body temperature, body
fluid, hormone secretion)
7.
Temporal Lobe
G. Center that controls heart rate and reflex actions, regulates
Controls motor activities and interprets sensation
blood pressure and breathing
8.
Parietal Lobe
H. “Master gland”; releases hormones controlling many body
9.
Occipital Lobe
I.
10. Spinal Cord
activities & Influences activities of many endocrine glands
Two bundles of axons that connect the hemispheres of the
brain so right & left sides can communicate
J.
11. Medulla Oblongata
Controls skeletal muscles, formation of words, and
personality
K. Branched fibers that receive neural impulses
12. Pons
L.
13. Dendrites
M. Thought to secrete melatonin (which is believed to play part
14. Axons
N. Four cavities in brain that contains cerebrospinal fluid
and protects the brain
O. Responsible for coordination movements, makes
movements smooth, helps maintain muscle tone and
equilibrium
P. Transmits neural messages from cell body towards
another neuron
Q. Controls many reflex activities of body; transmits
Organized to receive sensory information & control
muscles mostly from contralateral (opposite) side of
body
in regulation of sleep)
15. Central Nervous
System
16. Corpus Callosum
17. Pineal Gland
information back and forth from nerves of PNS to brain
19. Thalamus
R. Control center for entire organism; integrates incoming
information and determines appropriate responses.
S. Most highly evolved portion of brain
20. Pituitary Gland
T.
18. Ventricles
Sensory Association area – impulses from skin such as
pain and temperature are interpreted; area for
estimation of distances, sizes and shapes
