Central Nervous System

Question 0

Reticular formation

Answer 0

Midbrain area I. Which nuclei and fiber pathways are mixed, producing a netlike appearance; associated with sleep-wake behaviour and behavioural arousal

Question 1

Hindbrain

Answer 1

Evolutionarily the oldest part of the brain; contains the pons, medulla, an cerebellum, structures that coordinate and control most voluntary and involuntary movements

Question 2

Midbrain

Answer 2

Central part of the brain that contains neural circuits for hearing and seeing as well as orienting movements.

Question 3

Tectum

Answer 3

Roof (area above ventrical) of the midbrain; its functions are sensory processing, particularly visual and auditory, and the production of orienting movements.

Question 4

Tegmentum

Answer 4

Floor (area below the ventricle) of the midbrain; a collection if nuclei with movement-related, species specific, and pain perception functions.

Question 5

Orienting Movement

Answer 5

Movement related to sensory inputs, such as turning the head to see the source of a sound.

Question 6

Diencephalon

Answer 6

The “between brain” that integrates sensory and motor information on its way to the cerebral cortex.

Question 7

Hypothalamus

Answer 7

Diencephalon structure that contains many nuclei associated with temperature regulation, eating, drinking, and sexual behaviour.

Question 8

Thalamus

Answer 8

Diencephalon structure through which information from a sensory systems is integrated and projected into the appropriate region of the neocortex.

Question 9

Forebrain

Answer 9

Evolutionarily the newest part of the brain; coordinates advanced cognitive functions such as thinking, planning, and language; contains the limbic system basal ganglia and the neocortex.

Question 10

Neocortex

Answer 10

Newest, outer layer (“new bark”) of the forebrain, composed of about six layers of gray matter; creates our reality.

Question 11

Cytoarchitectonic map

Answer 11

Map f the neocortex based on the organization, structure, and distribution of cells

Question 12

Basal ganglia

Answer 12

Subcortical forebrain nuclei that coordinate voluntary movements of the limbs and body; connected to the thalamus and to the midbrain

Question 13

Parkinson’s disease

Answer 13

Disorder of the motor system correlated with a loss of dopamine in the brain characterized by tremors, muscle rigidity, and a reduction in voluntary movement.

Question 14

Cranial Nerve

Answer 14

One of a set of 12 nerve pairs that control sensory and motor functions of the head, neck, and internal organs.

Question 15

Vertebrae (sing. Vertebra)

Answer 15

The bones that form the spinal column

Question 16

Dermatome

Answer 16

Body segment corresponding to a segment of the spinal cord.
