Galen performed vivisection, or live experimentation, on animals to learn about the nervous system. What did Galen discover with his squealing pig experiment? A) Galen correctly identified that peripheral nerves could control bodily function B) Galen correctly identified the division between the central and peripheral nervous systems C) Galen demonstrated that tendons, ligaments and nerves were separate entities D) Galen demonstated that transection of individual nerves had little functional consequence.

If your index finger had to be amputated as a result of a freak what would happen to your S1 somatotopic map of your fingers? A) The neurons in S1 that had previously responded to stimulation on the index finger would begin to respond to stimulation of the thumb and middle finger B) The neurons in S1 that had previously responded to stimulation on the index finger would begin to respond to stimulation of the foot and toes C) The neurons in S1 that had previously responded to stimulation on the index finger would die and the neurons from the thumb and middle finger would reproduce and expand their respective maps D) None of the above

What is meant by the experimental ablation method of studying the brain? a. The approach in which identical experiments are conducted on numerous animals simultaneously b. The approach in which experiments are conducted on animal species to understand the function of the human brain c. The approach in which the brain is preserved with fixatives such as formaldehyde, sliced thin, and then studied with a microscope Od. The approach in which parts of the brain are systematically destroyed to determine their function

Macular degeneration is an eye disease that causes loss in the center of the field of vision. In this disease, the cone cells are the photoreceptor cells most affected. Therefore, this is a disorder involving the A) Retina B) Choroid layer C) Ciliary body D) Cornea

The reflex arc is the fastest way the body has to move a body part from danger or away from the source of pain. Have you ever noticed your own reflex response? Did you notice that you felt the pain after you yanked your hand away from the source of pain? Which is the sequence of structures involved in a reflex response? a. motor neurons → effectors → brain → sensory neurons → interneurons b. effectors → sensory neurons → brain → motor neurons c. sensory neurons → interneurons → motor neurons → effectors d. sensory neurons → motor neurons → interneurons → effectors

The plantar reflex is extensor on the left. Which of the following is the most likely site of a lesion? A) Genu of the internal capsule B) Medulla C) Midbrain D) Pons E) Posterior limb of the internal capsule

26) muscle tone is .... a) the ability of a muscle to efficiently cause skeletal movements  b) the feeling of well being following exercise  c) the condition of athletes after intensive training  d) a state of sustained partial contraction

When you look at a physical object, like a photograph, light waves emanating from the object stimulate receptors in your eye. Technically, the light waves that reach your eye are called a ____ stimulus, and the photograph would be considered a ____ stimulus. A) proximal; distal B) distal; proximal C) central; peripheral D) peripheral; central

Ozana was born with cataracts, which made her completely blind. When she was 14 years-old she underwent surgery to remove the cataracts, which allowed visual input to be transmitted to her brain for the first time. However, even though the surgery was a success, Ozana’s vision was never fully functional. A) Describe how the features of neural plasticity might help to explain why Ozana’s vision was not restored. B) Propose one factor that might have increased the chance that Ozana would develop the ability to see, and briefly explain why.
