Quiz 1

Question 1

The nervous system develops from embryonic tissue called

Answer 1

Ectoderm

Question 2

By the 21st day of development, a neural tube is formed when the edges of

Answer 2

the neural groove meet

Question 3

Neural crest becomes the

Answer 3

peripheral nervous system

Question 4

By the 7th week of development, these three areas divide again. This process is called?

Answer 4

Encephalization

Question 5

The telencephalon is responsible for the following functions:

Answer 5

Determines intelligence, Determines personality, Interpretation of sensory impulses, Motor function, Planning and Organization, Sense of smell, and Touch sensation

Question 6

What structure houses the thalamus, hypothalamus, pineal gland, and a number of related structures?

Answer 6

Diencephalon

Question 7

The tectum is the dorsal surface of the midbrain. It is responsible for

Answer 7

auditory/visual reflexes (like jumping when someone slams a door)

Question 8

Superior colliculi

Answer 8

controls visual reflexes

Question 9

Inferior colliculi

Answer 9

controls auditory reflexes

Question 10

What two structures play a role in Parkinson’s and dopamine?

Answer 10

Substania nigra and red nucleus

Question 11

Pons

Answer 11

The part of the metencephalon located on the brain stem that forms a bulge on the brain stem’s ventral surface. It is involved in motor control and sensory analysis, acting as the sensory/motor relay center.

Question 12

Cerebellum

Answer 12

The “cauliflower” piece in the back of the brain that is responsible for sensorimotor function (the part that helps regulate posture, balance, and coordination). Think of the “practice makes perfect” theory of sports, for example.

Question 13

Reticular formation

Answer 13

The reticular formation is comprised of 2 columns of neuronal nuclei with ill-defined boundaries, which go up through the medulla and into the mesencephalon. The reticular formation plays a role in arousal, and regulates your sleep/wake cycle. It is also associated with habituation (example – able to tune out background noise), somatic motor control (tone, balance, and posture), cardiovascular regulation and pain modulation.

Prosencephalon splits into

Answer 14

Telencephalon and Diencephalon

Question 15

Telencephalon splits into

Answer 15

Neocortex; Basal Ganglia; Amygdala; Hippocampus; Lateral Ventricles

Question 16

Diencephalon splits into

Answer 16

Thalamus; Hypothalamus; Epithalamus; Third Ventricle

Question 17

Mesencephalon splits into

Answer 17

Tectum; Tegmentum; Cerebral Aqueduct

Question 18

Rhombencephalon splits into

Answer 18

Metencephalon and Myelencephalon

Question 19

Metencephalon splits into

Answer 19

Cerebellum; Pons; Fourth Ventricle

Question 20

Myelencephalon splits into

Answer 20

Medulla Oblongata; Fourth Ventricle
