PAM Anatomy & Physiology Fundamentals 3

Question 1

Which body plane divides the body into superior and inferior portions?

Accepted Answer

Transverse (horizontal) plane

Answer

The transverse plane, also called the horizontal or axial plane, divides the body into superior (upper) and inferior (lower) sections.

Question 2

In the context of PAM application, understanding tissue thermosensitivity is important. Which tissue has the HIGHEST sensitivity to temperature changes?

Accepted Answer

Peripheral nerve tissue

Answer

Peripheral nerve tissue is highly sensitive to temperature, which is why both heat and cold modalities have profound effects on nerve conduction velocity.

Question 3

The stretch reflex (myotatic reflex) is mediated by which sensory receptor?

Accepted Answer

Muscle spindle (intrafusal fibers)

Answer

Muscle spindles detect changes in muscle length and initiate the stretch reflex via Ia afferent fibers, causing the stretched muscle to contract.

Question 4

Which of the following correctly pairs a joint type with its classification?

Accepted Answer

Hip joint = diarthrosis

Answer

The hip joint is a freely movable synovial joint, classified as a diarthrosis, specifically a ball-and-socket type.

Question 5

What is the function of osteoclasts in bone remodeling?

Accepted Answer

Resorbing bone tissue by releasing acids and enzymes

Answer

Osteoclasts are large multinucleated cells that resorb bone by secreting hydrochloric acid and proteolytic enzymes to dissolve the bone matrix.
