Question 1

What are the 4 brain lobes and where are they located?

Answer 1

Frontal (superior and anterior)

Parietal (superior and medial)

Occipital (posterior and inferior to parietal lobe)

Temporal (inferior to other 3 lobes)

Question 2

What functions are co-ordinated in the frontal lobe?

Answer 2

Voluntary motor activities

Pre-frontal cortex (personality, intellect, ‘higher’ self)

Question 3

What functions are co-ordinated in the parietal lobe?

Answer 3

Sensory input

Body orientation

Question 4

What functions are co-ordinated in the occipital lobe?

Answer 4

Visual

Question 5

What functions are co-ordinated in the temporal lobe?

Answer 5

Auditory

Speech

Question 6

What are the main landmarks of the brain?

Answer 6

Central sulcus: divides frontal and parietal lobes

Pre-central gyrus: runs anteriorly along central sulcus (primary motor area)

Post-central gyrus: runs posteriorly along central sulcus (primary somatosensory area)

Median longitudinal fissue: divides left and right hemispheres

Transverse central fissue: divides hemispheres and cerebellum
