Week 8_CNS continued

The two cerebral hemispheres are connected by a broad band of white matter called the __________

• corpus callosum

• intermediate mass

• vermis

• the pons

The post-central gyrus contains cells of the ___________

• primary motor cortex

• primary language centre

• primary auditory cortex

• primary sensory cortex

Why does the motor homunculus depict the hands, face and tongue hugely out of proportion?

• the brain area devoted to using those regions is vast

• more motor units are needed for fine control of those areas

• the cortical areas mapped for controlling those areas overlap with the sensory regions controlling those areas

Lateral sulci divides following lobes:

• Frontal & Temporal lobe

• Temporal & Occipital lobe

• Parietal & Frontal lobe

• Temporal & Parietal lobe

• Planning

• Coordination

• Repetition

• All of the above

Broca's area is known as______speech area.

• Motor

• Sensory

• Mixed

Prefrontal cortex is responsible for _____

• Personality

• Reasoning

• Judgement

• Cognition

The area posterior to the central sulcus is the_____
