Question 1

Which type of cartilage is best suited to resist both strong compression and strong tension forces, and where is it commonly found?

Accepted Answer

Fibrocartilage; found in the pubic symphysis and menisci of the knee

Question 2

During bone development, which process forms the frontal and parietal bones, and what is the origin tissue?

Accepted Answer

Intramembranous ossification; originates from mesenchyme

Question 3

Which cell type is primarily responsible for bone resorption, and what is the main mechanism by which it accomplishes this?

Accepted Answer

Osteoclasts; by secreting acids and enzymes to dissolve bone matrix

Question 4

A patient suffers a fracture. Which sequence correctly describes the basic steps in bone repair?

Accepted Answer

Formation of hematoma → fibrocartilaginous callus → bony callus → bone remodeling

Which bone is part of the axial skeleton and articulates with the mandible?

Accepted Answer

Temporal bone

Question 7

Which bones form the pectoral girdle, and what is their primary function?

Accepted Answer

Clavicle and scapula; attach the upper limbs to the axial skeleton

Question 8

Which of the following best describes the structural and functional differences between male and female pelves?

Question 16

Which arrangement pattern describes muscle fibers converging toward a single tendon, as seen in the pectoralis major?

Accepted Answer

Convergent

Question 17

In a lever system, which term describes the point where the bone pivots, and how does it relate to muscle action?

Accepted Answer

Fulcrum; the joint where the bone pivots

Question 18

Which lever class is exemplified by the action of the triceps at the elbow, where the fulcrum is between the effort and the load?

Accepted Answer

First-class lever

Question 19

During elbow flexion, which muscle acts as the prime mover (agonist), and which acts as the antagonist?

Accepted Answer

Biceps brachii; triceps brachii

Question 20

Which developmental scheme describes the origin of limb muscles?

Accepted Answer
