18. Regarding the oxygen-hemoglobin dissociation curve, a patient suffering from a fever would have a hemoglobin saturation curve shifted to the of a normal hemoglobin curve as an increase in temperature causes affinity for oxygen. a. left // higher b. left // lower c. right // higher. d. right // lower. e. None of these—temperature does not affect hemoglobin’s affinity for oxygen.

3. Is the patient hypertensive? If so to what degree?
4. How would you classify the patient’s heart rate?

What is steady state exercise?

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

2. 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

3. 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

4. The spinothalamic tract:
   1. is a motor tract
   2. connects the spinal cord to the thalamus
   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.

Identify the organs of the urinary system and any organs that are different between male and female.

Identify the basic function of each organ.

Explain the tissues of that organ and how they pertain to the process of propelling urine through the system.

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.

if one of the lobes of the cerebrum were damaged, would the person lose all functions of that lobe?
