Lesson 2

Question 1

Brain stem

Answer 1

This is where the brain connects to the spinal cord. Many involuntary
functions are controlled here like keeping the heart beating,
breathing, and digesting food.

Question 2

Cerebellum

Answer 2

The part of the brain located at the back and bottom of the brain. It
regulates balance, movement, and muscle coordination.

Question 3

Cerebrum

Answer 3

The largest and most complex portion of the brain. It controls
thought, learning, and many other complex activities. It is divided into
the left and right hemisphere, and each hemisphere is divided into 4
lobes.

Question 4

Corpus callosum

Answer 4

A thick band of nerve fibers that connects the left and right
hemispheres of the brain. It allows for communication between both
hemispheres.

Question 5

Dura mater

Answer 5

A tough, translucent membrane that protects the brain and spinal
cord.

Question 6

Frontal lobe

Answer 6

The top, front regions of the cerebrum. This lobe controls thinking,
decision-making, emotions, judgment, and voluntary movement.

Question 7

Hypothalamus

Answer 7

A region in the upper part of the brainstem that controls body
temperature, sleep, moods, hormonal body processes, hunger, and
thirst.

Question 8

Left hemisphere of brain

Answer 8

The left hemisphere of the brain is responsible for control of the right
side of the body, and is the more academic and logical side of the
brain.

Question 9

Nervous system

Answer 9

This system is made up of your brain, spinal cord, and all the nerves
in your body. The brain is the control center and the spinal cord is the
major highway to and from the brain.

Question 10

Occipital lobe

Answer 10

The region at the back of the cerebrum that controls vision and reading ability

Question 11

Olfactory bulb

Answer 11

A structure found in the brain that processes information about
odors, and is a key part responsible for the sense of smell.

Question 12

Optic chiasm

Answer 12

The area in the front of the brain where the optic nerves cross one
another. It controls vision and the optic nerve.

Question 13

Optic nerve

Answer 13

The nerve in your eye that transmits

information from your eye to your brain.

Question 14

Parietal lobe

Answer 14

The middle lobe of each cerebral 
hemisphere located between the frontal 
and occipital lobes (upper back of the 
head). It processes sensory information 
that has to do with taste, temperature, and 
touch.

Question 15

Right hemisphere of brain

Answer 15

The right hemisphere of the brain is
responsible for control of the left side of
the body, and is the more artistic and
creative side of the brain.

Question 16

Thalamus

Answer 16

A small structure at the top of the
brainstem that serves as a relay center for
sensory information, pain, attention, and
alertness.

Question 17

Temporal lobe

Answer 17

The region at the lower side of each
cerebral hemisphere (located at the sides
of the head). It processes sound and
certain memory functions.

Question 18

Blind spot

Answer 18

The spot in the back of each eye where the optic nerve is joined to
the retina. This small circular area does not contain rods or cones
(specialized cells in the eye that respond to light) and cannot
respond to light.
