  1. We visually are not aware of a “blind spot” when both eyes are open because____?

  1. the other eye is redundant so there is no need for it.
  2. your eyes have different focal points and thus would give different answers.
  3. light stimuli excite the same point on both retinas.
  4. the blind spots of our eyes are not on corresponding points.
  5. None of the answers are correct.

2.Sound, light, taste, touch and smell do not come in one level. We are able to describe the intensity of a stimulus (i.e. the intensity of ammonia salts or the brightness of a camera’s flash). What are the mechanisms used by the nervous system to communicate intensity via graded and action potentials?

Visit the following links, associated with the television show Monsters Inside Me, and then complete the assignment below. Adopt the first three parasites from the Parasite Pet Shop by putting the stages of their life cycle in order. First review the Meet the Parasite link and then watch the video clips. This will help you understand, and correctly complete, the life cycle of each parasite. You can also find these links on the Meet the Microbes: Eukaryotes Lecture Main Page. Ctrl+click to follow the links below.

  1. Meet the Pork Tape Worm

Video Clips “Pork Tape Worm” & “Pork Tape Worm In Brain”

  1. Disease / Medical Condition: pork tapeworm
  2. How do humans get contract disease (i.e. how is it transmitted)? undercooked pork that contains the cysts

  1. Signs and symptoms of disease: you can have seizures coma hallucinations or possibly even death
  2. Describe the course of the disease: they get infected in the human gut the cysts hatch into adult tapeworms where they can grow up to several metres long the adult worms lay eggs that are passed in human feces if a pig then eats the feces the eggs grow into cysts in its muscle tissue and the life cycle repeats
  3. How can this infection be prevented in humans?
  4. Type of parasite (bacteria, protozoan, fungus, helminth, insect, virus):
  5. Scientific name of parasite (properly formatted):
  6. How does this parasite evade the host’s immune system?
  7. List the order in which you placed the life cycle circles in the Adopt a Pet Parasite game (There is a sentence associated with each of the 4 circles.):

2. Choose the right answer:

The plateau phase of the ventricular action potential is caused by _______.

slow K+ channels opening
fast Na+ channels opening
fast voltage-gated Ca2+ channels opening
slow voltage-gated Ca2+ channels opening

3.. How is heart rate controlled?

Parasympathetic and sympathetic divisions of the ANS control heart rate.
Heart rate is controlled through the cardiac plexus.
Dual innervation controls the heart rate.
All the listed answers are correct.

A patient with left hemisphere dominance underwent a complete cerebral commissurotomy. During a study the patient was fitted with special contact lenses so that light would only be seen from the left visual field. The patient was briefly shown a picture of a watermelon. The patient was then asked what they saw in the picture. Finally, the patient was shown several objects including a watermelon and other fruit and was prompted to point to the object they saw previously in the picture. How will the patient respond on these tasks?

Group of answer choices

They will be able to describe what they saw but they will not be able to accurately point with their dominant hand

They will be able to describe what they saw but they will not be able to accurately point with their nondominant hand

They will not be able to describe what they saw but they will be able to accurately point with their dominant hand

They will not be able to describe what they saw but they will be able to accurately point with their nondominant hand
