• 
• 
• 
• 

Which of the following shows the correct arrangement of fibres in above diagram –

• 
• 
• 
• 

I. Cerebellum has very convoluted surface in order to provide the additional space for more neurons

II. The medulla is connected to the spinal cord

III. Medulla contains controlling centres for respiration, cardiovascular reflexes and gastric secretion

• All are correct

• Only I is correct

• Only I and III are correct

• Only II is correct

Immediate involuntary response to stimulus is –

• Sympathetic nervous system

In reflex action, the reflex arc is formed by –

• Muscle, receptor, brain

• Brain, spinal cord, muscle

• Receptor, spinal cord, muscle

• muscle, spinal cord, receptor

Destruction of the anterior horn cells of the spinal cord would result in loss of

• Commissural impulses

• Integrating impulses

• Sensory impulses

• Voluntary motor impulses

When a person thinks and solve problems, which area of the cerebrum is involved?

• Frontal lobe

• Parietal lobe

• Occipital lobe

• Temporal lobe

Which of the following structures or regions is incorrectly paired with its functions?

• Hypothalamus : production of releasing hormones and regulation of temperature, hunger and thirst.

• Limbic system : consists of fibre tracts that interconnect different regions of brain; controls movement.

• Medulla oblongata : controls respiration and cardiovascular reflexes.

• Corpus callosum : band of fibers connecting left and right cerebral hemispheres.
