Question 5

A person suffers a spinal cord injury at the level of T12. Which of the following is the most likely outcome?

Accepted Answer

Question 6

Which of the following best defines 'contralateral' as it applies to the nervous system?

Accepted Answer

Question 7

Which connective tissue layer directly surrounds individual axons within a peripheral nerve?

Accepted Answer

Endoneurium

Question 8

A patient is unable to feel pain in a specific region of the skin. Which type of receptor is most likely damaged?

Accepted Answer

Nociceptor

Question 9

Which of the following best describes the difference between sensation and perception?

Accepted Answer

Sensation is the detection of changes in the environment, while perception is the conscious interpretation of those stimuli.

Question 10

Which neurotransmitter is released by all preganglionic neurons in the autonomic nervous system?

Accepted Answer

Acetylcholine

Question 11

Which of the following is a key difference between the sympathetic and parasympathetic divisions of the autonomic nervous system?

Accepted Answer

Sympathetic division prepares the body for 'fight or flight', while the parasympathetic division promotes 'rest and digest' activities.

Question 12

A person is exposed to a stressful situation. Which of the following physiological responses is most likely to occur due to sympathetic nervous system activation?

Accepted Answer

Increased heart rate and dilation of bronchioles

Question 13

Which of the following best describes 'dual innervation' in the autonomic nervous system?

Accepted Answer

Organs receive input from both the sympathetic and parasympathetic divisions, allowing for dynamic antagonism.

Question 14

Which of the following is NOT considered a special sense?

Accepted Answer

Touch

Accepted Answer

Benign paroxysmal positional vertigo (BPPV)

Question 17

Which of the following best describes the role of the maculae in the vestibular apparatus?

Accepted Answer

Detects linear acceleration and head position relative to gravity

Question 18

A person is experiencing motion sickness while traveling by boat. Which sensory conflict is most likely responsible for this condition?

Accepted Answer

Mismatch between visual input and vestibular signals from the inner ear

Question 19

Which of the following best describes the pathway of sound conduction to the fluids of the internal ear?

Accepted Answer
