Answer 8

Deep groove that separates the frontal and parietal lobes from the temporal lobe of the cerebrum.

Question 9

temporal lobe

Answer 9

region of the Cerebrum located medial to the temporal bone; processes information associated with hearing and equilibrium.

diencephalon

Answer 13

a major part of the brain like that frontal lobe or the parietal except this part of the brain is made up of the thalamus, hypothalamus and parts of the pituitary and pineal gland.

Question 14

intermediate mass

Answer 14

a flattened gray band of tissue connecting the two halves of the thalamus

Question 15

hypothalamus

Answer 15

region inferior to the thalamus; main regulatory center involved in visceral control of the body and maintenance of overall homeostasis.

pea like structure posterior to hypothalamus; function as relay station in olfactory pathway.

Question 17

olfactory pathway

Answer 17

set of nerve fibers conducting impulses

infundibulum

Answer 18

neural stalk originating near mamillary bodies; connects pituitary gland to hypothalamic.

Question 19

pituitary gland

Answer 19

Glandular tissue hanging under the hypothalamus; important producer and releaser of endocrine hormones that regulate growth and homeostasis and metabolism.

Question 20

pineal gland, such lolzzzzzzzzzz

Answer 20

glandular tissue posterior to the thalamus; important producer and releaser of endocrine hormones.

Question 21

superior colliculus

Answer 21

Question 22

corpora quadrigemina

Answer 22

Reflex centers involving vision and hearing.

Question 23

inferior colliculus

Answer 23

Part of the midbrain one half of the corpora quadrigemina; contains nerve reflex centers involved in auditory reflexes.

Question 24

Pons

Answer 24

Region of brain stem between the midbrain and medulla oblongata; serves as the connection between the two regions, and the cerebellum.

Question 25

medulla oblongota

Answer 25

the most inferior portion of the brain stem, contains cardiac, vasomotor, and respiratory centers.

Question 26

vasomotor center

Answer 26

regulates blood pressure and other homeostatic processes.

Question 27

Pyramid

Answer 27

longitudinal ridge flanking mid-line of the medulla oblongata; contains fiber tracts running between the cerebrum and spinal cord.

Question 28

vermis

Answer 28

mid-line of tissue, that looks wormlike, connects the two cerebellar hemispheres.

Question 29

follia

Answer 29

fine, transversely oriented pleat like gyri on the surface of the cerebellum, increases surface area.

Question 30

sulci and gyri

Answer 30

the fissures and bumps on the cerebellum respectively.

Question 31

arbor vitae

Answer 31

distinctive pattern of white matter deep within the cerebellum; resembles a branching tree.

Question 32

cerebellar pednuncles

Answer 32

connection points between the cerebellum and brainstem; contains fiber tracts running between the cerebellum and midbrain, pons, and medulla

Question 33

lateral ventricles

Answer 33

C Shaped chambers buried deep within each hemisphere; house choroid plexi that produce cerebrospinal fluid that fuels the brain.

Question 34

septum pellucidum

Answer 34

thin vertical partition that separates lateral ventricles.

Question 35

third ventricle

Answer 35

chamber surrounding the thalamus; houses a choroid plexus that produces cerebrospinal fluid.

Question 36

interventricular froamen

Answer 36

small opening between each lateral ventricle and the third ventricular; drains cerebrospinal fluid.

Question 37

forth ventricle

Answer 37

chamber that occupies the space between the dorsum of the pons/medulla and the overlying cerebellum; houses cerebrospinal fluid

Question 38

cerebral aquaduct

Answer 38

narrow passageway between the third ventricle and the fourth ventricle; contains cerebrospinal fluid

Question 39

central canal

Answer 39

central opening that runs through the medulla oblongata and is continuous with the spinal cord; contains cerebrospinal fluid.
