brain parts

Question 1

Cerebrum

Answer 1

The most anterior part of the brain, located in the front area of the skull and consisting of two hemispheres, left and right. It is responsible for the integration of complex sensory and neural functions and the initiation and coordination of voluntary activity in the body. (pronounced suh-REE-brum)

Question 2

Corpus Callosum

Answer 2

A broad band of nerves that connects the left and right hemispheres of the cerebrum. (Pronounced corp-us cal-lo-sum)

Question 3

Frontal Lobes

Answer 3

The frontal lobes play a large role in your behavior and personality, such as planning, voluntary muscle movements, mood, emotions, social interactions, and attention, and are also involved in memory retrieval and storage.

Question 4

Motor Cortex

Answer 4

The part of the brain where nerve impulses initiate voluntary muscular activity

Question 5

Parietal Lobes

Answer 5

Responsible for sensing touch, spatial processing (being able to tell where objects are in space), language, and memory. (Pronounced par-EYE-it-al)

Question 6

Sensory Cortex

Answer 6

All received sensory input signals, such as touch and taste, are sent through neurons to the sensory cortex to be processed.

Question 7

Occipital Lobes

Answer 7

Primarily responsible for visual perception and are involved in some forms of visual, short-term memory. (Pronounced OX-SIP-it-al)

Question 8

Visual Cortex

Answer 8

The part of the cerebral cortex that receives and processes sensory nerve input from the eyes.

Question 9

Optic Nerves

Answer 9

A pair of nerves transmitting input signals to the brain from the retina at the back of the eye.

Question 10

Optic Chiasm

Answer 10

The X-shaped structure formed at the point below the brain where the two optic nerves cross over each other.

Question 11

Auditory Cortex

Answer 11

The part of the temporal lobe that processes auditory input signals.

Question 12

Olfactory Bulbs

Answer 12

The structure in the front of the brain responsible for receiving and processing smells.

Question 13

Olfactory Tracts

Answer 13

The nerve fibers that connect the olfactory bulbs to the temporal lobes.

Question 14

Brain Stem

Answer 14

The center trunk of the brain that continues downward to form the spinal cord.

Question 15

Cerebellum

Answer 15

The part of the brain at the back of the skull in vertebrates. Its function is to coordinate and regulate muscular activity. (Pronounced sair-uh-BELL-um)

Question 16

Hypothalamus

Answer 16

A region of the brain below the thalamus that coordinates both the autonomic nervous system and the activity of the pituitary, controlling body temperature, thirst, hunger, and other homeostatic systems, and involved in sleep and emotional activity.

Question 17

Thalamus

Answer 17

Either of two masses of gray matter lying between the cerebral hemispheres, relaying sensory information and acting as a center for pain perception.

Question 18

Pituitary Gland

Answer 18

A tiny organ that serves as the primary gland for the body, producing several hormones and activating other glands to produce hormones.
