Perception of Right Visual Field

Consider a situation in which an object is visible in your right visual field (to the right of "straight ahead").

  • Light from this object will stimulate receptor cells in the  (right or left) half of each retina.
  • The impulses from this area of the retina travel via visual pathways to the visual cortex of the  (right or left) occipital lobe.
  • Thus, information regarding your right visual field is perceived by your  (right or left) visual cortex.

  1. The toothpick poking activity in lab:
    1. measured adaptation as more nerve endings became involved with two toothpicks
    2. showed a lower density of nerve endings near the base of the finger compared to the tip
    3. both a. and b. are correct
    4. neither a. nor b. is correct

  1. The perceptions of temperature and pressure:
    1. depend on different sensory endings (temperature endings not same as pressure endings)
    2. are subject to the effects of adaptation
    3. both a. and b. are correct
    4. neither a. nor b. is correct

  1. Rods:
    1. release an excitatory neurotransmitter, which stimulates “seeing” (light)
    2. release less neurotransmitter in the light than when in the dark
    3. both a. and b. are correct
    4. neither a. nor b. is correct

Summarize the material covered in today’s lab. Name and describe each of the phases of the cardiac cycle. Be sure to include the events that occur during each phase. Focus on the mechanical events (contraction and relaxation) of the chambers, the pressure changes in the heart, the position of the valves, and the heart sounds. Be sure to explain what causes each of the events you describe.

Explain how the sympathetic nervous system (and endocrine system) act directly to regulate heart rate and thus cardiac output. Include a detailed description of the mechanism (include the target cells, the proteins, signaling molecules, ions, and changes in membrane pontial where appropriate) and explain how the mechanism operates to alter heart rate.Explain how the parasympathetic nervous system acts to directly regulate cardiac output (1 mechanism). Discuss each mechanism separately including a detailed description of each mechanism (include the target cells, the proteins, signaling molecules, ions, and changes in membrane pontial where appropriate). Make clear how each affects cardiac output. This shoul require about half a page.Explain in detail the Frank-Starling law of the heart. Be sure to define what it is, and describe how it operates (the mechanism). Explain why it is an important way that cardiac output is regulated. Demonstrate your understanding by describing a particular scenario when it would operate and its significance.

Which of the following is true

Select one:

a. Vasomotor syncope may occur when you lie down after standing up for a long time

b. Vasomotor syncope is caused by increased venous return, which causes excessive stimulation of the baroreceptor reflex

c. Vasovagal syncope occurs in response to a disturbing situation that causes over-stimulation of the SNS

d. Contraction of the lower leg muscles helps to prevent vasomotor syncope because it increases the pressure gradient from the peripheral veins to the right atrium
