  9. area lies in the left temporal lobe (Fig 3). Damage to this area causes Wernicke's aphasia. The individual may speak in long sentences that have no meaning, add unnecessary words, and even create new words. They can make speech sounds, however they have difficulty understanding speech and are therefore unaware of their mistakes.

  3. gland is located behind the third ventricle. It helps regulate the body’s internal clock and circadian rhythms by secreting melatonin. It has some role in sexual development.
  4. is located in the floor of the third ventricle and is the master control of the autonomic system. It plays a role in controlling behaviors such as hunger, thirst, sleep, and sexual response. It also regulates body temperature, blood pressure, emotions, and secretion of hormones.
  5. nterprets vision (color, light, movement)
  6. is located under the cerebrum. Its function is to coordinate muscle movements, maintain posture, and balance.
  7. is the largest part of the brain and is composed of right and left hemispheres. It performs higher functions like interpreting touch, vision and hearing, as well as speech, reasoning, emotions, learning, and fine control of movement.
  8. acts as a relay center connecting the cerebrum and cerebellum to the spinal cord. It performs many automatic functions such as breathing, heart rate, body temperature, wake and sleep cycles, digestion, sneezing, coughing, vomiting, and swallowing.
  9. and organization
  10. and visual perception
  11. area lies in the left frontal lobe (Fig 3). If this area is damaged, one may have difficulty moving the tongue or facial muscles to produce the sounds of speech. The person can still read and understand spoken language but has difficulty in speaking and writing (i.e. forming letters and words, doesn't write within lines) – called Broca's aphasia.

  6. A molecule capable of accepting electrons and becoming reduced during photosynthesis.
  7. The pigment and protein complex that is responsible for producing the proton gradient required for ATP and absorbs light at the 680 nm wavelength.
  8. Series of protein complexes that transfer electrons to electron acceptors from electron donors through redox reactions in a specific direction across the thylakoid membrane. The movement of hydrogen ions is coupled with this. When hydrogen ions move through the protein and down the electron transport chain, ATP is created.
