A neuron with a cell body located in the CNS whose primary function is connecting other neurons is called a(n):
- A. efferent neuron
- B. afferent neuron
- C. interneuron
- D. glial cell
Correct Answer: C
Rationale: Interneurons are neurons located entirely within the CNS that connect other neurons. Efferent neurons transmit signals from the CNS to effectors, afferent neurons transmit signals from receptors to the CNS, and glial cells and satellite cells are supportive cells. Thus, C is the correct answer.

The classic ketogenic diet is typically initiated with what macronutrient ratio?
- A. 4 g of fat to 1 g of protein and carbohydrate
- B. 4 g of carbohydrate to 1 g protein
- C. 4 g of protein to 1 g of carbohydrate
- D. 4 g of protein to 1 g of fat and carbohydrate
Correct Answer: A
Rationale: The classic ketogenic diet is initiated with a 4:1 ratio of fat to combined protein and carbohydrates. This high-fat, low-carbohydrate ratio is designed to induce ketosis, a metabolic state where the body uses fat as its primary energy source, which can help reduce seizures in epilepsy.
Which nerve projects to the hypothalamus to indicate the level of light stimuli in the retina?
- A. glossopharyngeal
- B. oculomotor
- C. optic
- D. vagus
Correct Answer: C
Rationale: The correct answer is C: optic nerve. The optic nerve carries visual information from the retina to the brain, including the hypothalamus. Light stimuli levels are detected by the retina and transmitted via the optic nerve to the hypothalamus for regulating various physiological processes.
A: glossopharyngeal - This nerve is responsible for taste and some motor functions in the throat, not related to light stimuli detection in the retina.
B: oculomotor - This nerve controls eye movements, not directly involved in transmitting light stimuli levels to the hypothalamus.
D: vagus - This nerve is responsible for parasympathetic functions in the body, not related to processing light stimuli information in the retina.
What important information should you provide to a post-operative CTS patient for discharge?

- B. Hand movements will be restricted for 4€”6 weeks after surgery.
- C. Frequent pain medication dosages will no longer be necessary.
