Week 5

Question 1

Divisions of the brain

Answer 1

Forebrain, midbrain, hindbrain

Question 2

Forebrain

Answer 2

Telencephalon: Contains structures such as cerebral cortex, limbic system and basal ganglia

Diencephalon: Contains thalamus and hypothalamus

Question 3

Midbrain

Answer 3

Location of the superior and inferior colliculi

Question 4

Hindbrain

Answer 4

Contains medulla, pons, cerebellum, and the reticular formation

Question 5

Medulla

Answer 5

contains circuits of neurons that control functions vital for survival
such as heart rate, blood pressure, and respiration

Question 6

Pons

Answer 6

includes a bridge of fibres that connect the brainstem with the
cerebellum. The pons also contains several clusters of nuclei. One of
these clusters that runs through the pons is the reticular formation
which has an influence on our level of consciousness and alertness

Question 7

Cerebellum

Answer 7

The cerebellum is a relatively large structure located behind the brain
stem. It is critical to the co-ordination of movement and balance

Question 8

Superior (anterior) colliculi

Answer 8

– relay visual information and are important for

visual attention.

Question 9

Inferior (posterior) colliculi

Answer 9

relay auditory information and are important for

auditory attention.

Question 10

Thalamus

Answer 10

relay station through which all sensory information (except smell)
must pass to get to the cerebral cortex. The thalamus filters and
begins to organise the sensory input.

Question 11

Hypothalamus

Answer 11

The hypothalamus plays a major role in the regulation of basic
biological drives such as hunger and thirst. It also controls the
autonomic nervous system and is involved with the regulation of body
temperature.

Question 12

Basal ganglia

Answer 12

The basal ganglia are a group of structures crucial for planning and
producing movement

Question 13

Limbic System

Answer 13

– Two important structures of the limbic system are the hippocampus
and the amygdala.
– The hippocampus plays an important role in memory, particularly in
the consolidation of new memories (learning).
– The amygdala, located immediately in front of the hippocampus,
serves a vital role in processing emotional information, particularly the learning of fear responses.

Question 14

Occipital Lobes

Answer 14

Concerned with many

aspects of vision.

Question 15

Parietal Lobes

Answer 15

Concerned with
perception of stimuli
related to touch,
pressure, temperature
and pain.

Question 16

Temporal Lobes

Answer 16

Concerned with
perception and
recognition of auditory
stimuli (hearing) and
memory

Question 17

Frontal Lobes

Answer 17

Concerned with reasoning,
planning, parts of speech
and movement (motor
cortex), emotions, and
problem-solving
