10 parts of the brain

Question 1

Largest part of the brain; divided into the right and left hemispheres; composed of the frontal, parietal, occipital, and temporal lobes

Answer 1

Cerebrum

Question 2

Composed of the pons, midbrain, and the medulla oblongata

Answer 2

Brain Stem

Question 3

Composed of the thalamus and the hypothalamus

Answer 3

Diencephalon

Question 4

This structure means bridge; it helps regulate breathing rate and rhythym

Answer 4

Pons

Question 5

Brain structure that protrudes from under the occipital lobe; concerned primarily with the coordination of skeletal muscle activity

Answer 5

Cerebellum

Question 6

The precentral gyrus of this cerebral lobe is the major motor cortex; nerve impulses generate in the motor area control voluntary muscle activity

Answer 6

Frontal Lobe

Question 7

Plays a key role in personality development, emotional and behavioral expression, and performance of high level thinking and learning tasks

Answer 7

Frontal Lobe

Question 8

Cerebral lobe that contains the frontal eye fields; a motor homunculus lives here; controls motor speech (broca’s area)

Answer 8

Frontal Lobe

Question 9

The central sulcus separates the frontal lobe from this lobe; the postcentral gyrus of this cerebral lobe is the primary somatosensory area

Answer 9

Parietal Lobe

Question 10

A sensory homunculus lives here

Answer 10

Parietal Lobe

Question 11

Cerebral lobe that contains the auditory (hearing) cortex and the olfactory (smelling) cortex

Answer 11

Temporal Lobe

Question 12

Damage to this lobe causes cortical deafness

Answer 12

Temporal Lobe

Question 13

Called the emotional brain

Answer 13

Limbic System

Question 14

This widespread group of cells is concerned with the sleep-wake cycle and consciousness; signals passing from this structure to the cerebral cortex keep us awake

Answer 14

Reticular Formation

Question 15

Cerebral lobe that is primarily concerned with vision; damage to this lobe causes cortical blindness

Answer 15

Occipital Lobe

Question 16

Part of the diencephalon that controls the pituitary gland; also helps control the autonomic nervous system, water, balance, and body temperature

Answer 16

Hypothalamus

Question 17

We first become aware of pain at this level of the diencephalon; doesn’t allow us to determine type of pain or where its coming from

Answer 17

Thalamus

Question 18

Part of the diencephalon that acts as a relay and sorting station for most sensory fibers

Answer 18

Thalamus

Question 19

Part of the brain stem that connects the brain to the spinal chord; crossing of the motor fibers occurs here; part of the brain stem that contains the emetic (vomit) center

Answer 19

Medulla Oblongata

Question 20

Part of the brain stem called the vital center because it regulates processes such as blood pressure, heart rate, and respirations

Answer 20

Medulla Oblongata

Question 21

Part of the brain stem that contains the vomiting center; Receives info from the chemoreceptor trigger zone

Answer 21

Medulla Oblongata

Question 22

Bands of white matter that join the right and left cerebral hemispheres

Answer 22

Corpus Callosum
