Structures of the brain and what it controls.

Structures of the brain :



Cerebrum - divided into 4 fissures:
  • frontal lobe - site of personality, memory, reasoning, concentration, and motor control of speech
  • parietal lobe - site of sensation, integration of sensory information and spatial relationships
  • temporal lobe - site of hearing, speech, memory, and emotion
  • occipital lobe - site of vision and involuntary eye movements


Thalamus - receives inputs from all the sense except the olfaction ( sense of smell)

Hypothalamus - controls sleep and wakefulness, temperature, respiration, blood pressure, sexual arousal, fluid balance and emotional response.

Cerebellum - controls muscle movement regulates muscle tone, maintains balance and controls posture. 

Midbrain - mediates pupillary reflexes and eye movement

Pons - regulates perspiration 

Medulla Oblongata  - contains vomiting, vasemotor, respiratory, and cardiac centers.
