Dysdiadochokinesia refers to ___________.
- A. inability to walk
- B. excessive movements of the appendages
- C. ignoring one side of the body opposite brain damage

Which of these physiological changes would not be considered part of the sympathetic fight-or-flight response?
- A. increased heart rate
- B. increased sweating
- C. dilated pupils
- D. increased stomach motility
Correct Answer: D
Rationale: The correct answer is D: increased stomach motility. In the sympathetic fight-or-flight response, the body prioritizes blood flow to essential organs and muscles, leading to decreased activity in non-essential functions like digestion (stomach motility). This is to conserve energy for immediate action. Increased heart rate, sweating, and dilated pupils are all part of the fight-or-flight response as they prepare the body for quick action and heightened awareness.
Which is the CORRECT myotome?

Which technique is used to assess the cerebellum?
- A. Application of a pointed tip of a paper clip to lightly prick various areas of the upper and lower extremities for pain
- B. Having the patient walk on the heels and hen on the toes to test for balance
- C. With the patient's eyes closed, grasping his or her finger or toe and moving its position up or down to determine if the patient perceives that the digit has moved
- D. Having the patient lie supine and flex the hips and knees to test for mobility
Correct Answer: B
Rationale: Assessing the cerebellum involves testing balance and coordination. Having the patient walk on their heels and toes evaluates cerebellar function. Pain sensation, proprioception, and mobility are assessed through other techniques.
