Question 3

Which cranial nerve is tested by asking a patient to follow your finger with their eyes, and is responsible for most eye movements?

Accepted Answer

CN III (Oculomotor)

Question 4

Which type of receptor is stimulated by changes in chemical concentrations, such as the smell of food?

Accepted Answer

Chemoreceptor

Question 5

Which of the following best describes the function of the meninges?

Accepted Answer

Protect and support the brain and spinal cord

Question 6

A patient with Bell’s palsy will most likely exhibit which symptom?

Accepted Answer

Paralysis of facial muscles on one side

Question 7

Which equation best represents the relationship between frequency ($$f) $$and wavelength ($$\lambda) of $$brain waves, given the speed of propagation ($$v$$)?

Accepted Answer

$$f = \frac{v}{\lambda}$$

Question 8

Which type of receptor adapts quickly to a constant stimulus, such as wearing a watch?

Accepted Answer

Phasic mechanoreceptors

Question 9

During the regeneration of nerve fibers in the peripheral nervous system, which step is essential for successful regrowth?

Accepted Answer

Guidance by Schwann cells

Question 10

Why can neurons in the spinal cord not regenerate after injury, unlike peripheral nerves?

Accepted Answer

Spinal cord neurons lack Schwann cells and are inhibited by glial scars

Question 11

Which cranial nerve is responsible for the sense of smell, and how is it tested?

Accepted Answer

CN I (Olfactory); by asking the patient to identify familiar scents

Accepted Answer

Neurotransmitter reuptake

Question 15

Which equation would you use to calculate the conduction velocity ($$v) of a $$nerve impulse, given the distance ($$d) $$and time ($$t) it $$takes to travel?

Accepted Answer

$$v = \frac{d}{t}$$

Question 16

Which aspect of sensory perception allows you to recognize a familiar melody regardless of the instrument playing it?

Accepted Answer

Pattern recognition

Question 17

Which cranial nerve is classified as a mixed nerve, providing both sensory and motor functions?

Accepted Answer

Question 18

Which disorder is characterized by rapid, involuntary eye movements?

Accepted Answer

Nystagmus

Question 19

In the patellar reflex, which sequence correctly describes the flow of information?

Accepted Answer

Question 20

Which equation would you use to determine the total number of cranial nerves ($$N) if $$you know the number of sensory ($$S$$), motor ($$M$$), and mixed ($$X) $$nerves?

Accepted Answer

$$N = S + M + X$$
