Coordination and Response

This topic will be split in TWO class sessions:

• Nervous System and the Brain
• The Eye and the Hormone System

YOU NEED TO KNOW HOW TO:


NERVOUS SYSTEM AND THE BRAIN

1. State that the nervous system - brain, spinal cord and nerves - serves to coordinate and regulate bodily functions.
2. Identify the central nervous system (CNS) on a diagram.
3. Identify the following on a diagram of the brain: cerebrum, cerebellum, pituitary gland, hypothalamus, medulla, spinal cord, nerves.
4. Describe the functions of the above named structures, and relate to how they each contribute to coordinating bodily functions.
   
5. Outline the functions of sensory neurons, relay neurons and motor neurons.
6. Provide a detailed outline on how a "reflex action/arc" occurs.

THE EYE AND THE HORMONE SYSTEM

1. State the components of the EYE and their functions.
2. State how the eye produces a focused image of near and distant objects.
3. Describe the pupil reflex in response to bright and dim light
4. define a hormone as a chemical substance, produced by a gland, carried by the blood, which alters the activity of one or more specific target organs and is then destroyed by the liver.
5. State the role of the hormone adrenaline in boosting the blood glucose concentration and give examples of situations in which this may occur
6. Describe the signs (increased blood glucose concentration and glucose in urine) and treatment (administration of insulin) of diabetes mellitus.

P.S. Congratulations to Krystal and Ishaan for having the two highest scores in the second course exam (95 and 90, respectively), and to Arvin and Vedish for having the two most improved scores (by 27 and 22 marks respectively).

Also, it is nice to note that the class average also improved, even though these were harder, more complex topics. Good job, and keep working!
