Answer 1

Medulla
Pons
Cerebellum

Question 2

What is the FOREBRAIN made up of?

Answer 2

Thalamus
Hypothalamus
Cerebrum

Question 3

What is the MIDBRAIN made up of?

Answer 3

The reticular formation

Question 4

Where and what is the PONS responsible for?

Answer 4

Sits above the medulla, is a continuation of the spine.

receives info from the visuals to control eyes and body actions

Question 5

Where and What is the MEDULLA responsible for?

Answer 5

First part of the continuation of the spine

It’s role is to control breathing, heartbeat and digestion

Question 6

What and where is the CEREBELLUM responsible?

Answer 6

Walnut shaped area responsible for receiving info from the Pons

It coordinates sequences of body movements

Question 7

What is the RETICULAR FORMATION responsible and where is it?

Answer 7

Mostly situated in mid brain it partly falls into the hindbrain

Involved in the sleep wake cycle

Question 8

Where is the CEREBRUM and what is it involved in?

Answer 8

Largest part of the brain and responsible for higher order thinking

Question 9

What is the AMYGDALA?

Answer 9

It is an almond Shaped structure located in the medial temporal lobe and is involved in learning and forming emotional memories and responses

Question 10

What is the HIPPOCAMPUS?

Answer 10

A finger sized curved structure located in the medial temporal lobe involved in memory particularly long term memory

Question 11

What is the HYPOTHALAMUS and what is it’s role?

Answer 11

It a small structure involved in survival actions

Sleep, regulation of body temp, expression of emotions and the 4 f’s (fight feed flee and fornication)

Question 12

What is the THALAMUS and what does it do?

Answer 12

Located beneath the cerebral cortex and is divided into two egg shaped parts one in each hemisphere.

It receives info from ears, eyes, skin and other sensory organs (not nose)

Overall it regulates activity in the cortex

Question 13

What is CONTRALATERAL ORGANISATION?

Answer 13

It is the term used to describe how the right side of the brain controls the left side of the body and the left side of the brain controls the right side of the body.

Question 14

What is the role of the CEREBRAL CORTEX?

Answer 14

It is the outer layer of the forebrain and is responsible for receiving info from the environment and controls out responses

Involved in higher order thinking including planning and solving problems

Also involved in memory, language and regulation of emotions

Question 15

What are the lobes of the cerebral cortex?

Answer 15

Frontal, parietal, temporal and occipital

Question 16

What are the PRIMARY CORTICES?

Answer 16

They are the primary visual cortex, primary auditory cortex, primary somatosensory cortex and primary motor cortex

Question 17

What is the responsibility of the FRONTAL lobe?

Answer 17

It is the largest of the four lobes and is involved in initiating movement, language, planning, judgement, problem solving, aspects of personality, regulation of emotions.

Question 18

What is the role of the PARIETAL lobe?

Answer 18

Most of the parietal lobe is take up by the somatosensory cortex.

It’s role is to Receive sensations e.g touch, pressure, temp and body pain

Question 19

What is the role of the TEMPORAL lobe?

Answer 19

It processes auditory info. The primary auditory cortex is located in the upper part of the temporal lobe.

Question 20

What is the role of the OCCIPITAL lobe?

Answer 20

It is entirely concerned with vision. It receives info from the retina. Info from the LVF is processed on the right side of the brain vice versa.

Question 21

What is HEMISPHERIC SPECIALISATION?

Answer 21

Where the two hemispheres work together while at the same time having their own specialisations. Connecting through the corpus callosum.
