Vocabulary Quiz 8

Question 1

Answer 1

Arachnoid Villi

Question 2

A barrier consisting of specialized brain capillaries and astrocytes that prevents the passage of materials from the blood to the cerebrospinal fluid and brain

Answer 2

Blood-Brain Barrier

Question 3

The motor area of the brain in the frontal lobe that translates thoughts into speech

Answer 3

Broca’s Area

Question 4

The part of the brain lying posterior to the medulla oblongata and pons; governs balance and coordinates skilled movements

Answer 4

Cerebellum

Question 5

The surface of the cerebral hemispheres, 2-4 mm thick, consistinf of gray matter; arranged in six layers of neuronal cell bodies in most areas

Answer 5

Cerebral Cortex

Question 6

Second of three basic regions of each cerebral hemisphere; responsible for communication between cerebral areas and between cerebral cortex and lower CNS centers; consists mainly of myelinated fibers bundled into large tracts

Answer 6

Cerebral White Matter

Question 7

A fluid produced by ependymal cells that cover choroid plexuses in the ventricles of the brain; the fluid circulates in the ventricles, the central canal, and the subarachnoid space around the brain and spinal cord

Answer 7

Cerebrospinal Fluid

Question 8

Question 17

Portion posterior to the frontal lobe, responsible for sensations such as pain, temperature, and touch

Answer 17

Parietal Lobe

Question 18

The part of the brainstem that forms a “bridge” between the medulla oblongata and the midbrain, anterior to the cerebellum

Answer 18

Pons

Question 19

An area on each hemisphere of the cerebral cortex near the temples that is the primary receiving area for auditory information

Answer 20

Temporal Lobe

Question 21

Two egg-shaped masses of gray matter, main relay center between the brain stem and the cerebrum, and registers conscious recognition of pain and temperature, and is concerned with certain emotions

Answer 21
