Multiple Choice Questions About Skeletal System Questions
Question 1 of 5
Bones grow in length at the:
Correct Answer: C
Rationale: The epiphyseal plate (growth plate), between the epiphysis and diaphysis, is where long bones grow in length via cartilage ossification. The epiphysis is the end, diaphysis the shaft, and periosteum the outer layer, making 'epiphyseal plate' correct.
Question 2 of 5
The bones that serve as pathways for ducts that carry tears from the eyes to the nose is the bone.
Correct Answer: B
Rationale: The lacrimal bones, near the eyes, contain the nasolacrimal duct, channeling tears to the nasal cavity. The ethmoid, maxillae, and nasal bones are nearby but lack this duct, making 'lacrimal' correct.
Question 3 of 5
What is the only bone in the body that does not articulate with another bone?
Correct Answer: B
Rationale: The hyoid bone, in the neck, is unique as it does not articulate with any bone, suspended by ligaments. The patella, phalanges, and occipital all articulate, making 'hyoid' correct.
Question 4 of 5
The ribs that attach to the thoracic vertebrae and directly to the sternum via costal cartilage are called ribs.
Correct Answer: C
Rationale: Vertebrosternal (true) ribs (pairs 1-7) attach to thoracic vertebrae and directly to the sternum via their own costal cartilage. Vertebral are floating, and vertebrochondral share cartilage, making 'vertebrosternal' correct (incomplete options assumed).
Question 5 of 5
The head of the humerus articulates with the glenoid cavity of the:
Correct Answer: D
Rationale: The humerus head articulates with the glenoid cavity of the scapula, forming the shoulder joint. The femur is thigh, radius is forearm, and os coxa is hip, making 'scapula' correct.
