An action potential:
- A. is essential for nerve impulse propagation
- B. involves the influx of negative ions to depolarize the membrane
- C. involves the outflux of negative ions to depolarize the membrane
- D. involves the outflux of positive ions to depolarize the membrane
Correct Answer: A
Rationale: An action potential is essential for nerve impulse propagation, as it is the electrical signal that travels along the neuron. It involves the influx of positive sodium ions to depolarize the membrane, not negative ions or potassium ion movements. Therefore, A is the correct answer.

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.
The ________ ________ consists of glands that secrete hormones:
- A. nervous system
- B. immune system
- C. endocrine system
- D. cerebral cortex
Correct Answer: C
Rationale: The endocrine system consists of glands that secrete hormones into the bloodstream to regulate various bodily functions, such as metabolism, growth, and reproduction. Key glands include the pituitary, thyroid, and adrenal glands. Hormones act as chemical messengers, influencing target organs and tissues to maintain homeostasis. The endocrine system works closely with the nervous system to coordinate the body's responses to internal and external changes.
