Multiple Choice Questions About Skeletal System Questions
Question 1 of 5
The diaphysis predominately composed of:
Correct Answer: C
Rationale: The diaphysis, or shaft, of a long bone is primarily compact bone, providing strength and support. Spongy bone is in the epiphyses, hyaline cartilage covers joint surfaces, and fibrous tissue forms membranes like the periosteum, making 'compact bone' the correct answer.
Question 2 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 3 of 5
The paranasal sinuses drain into the and the mastoid sinuses drain into the
Correct Answer: B
Rationale: Paranasal sinuses (frontal, maxillary, etc.) drain into the nasal cavity via ducts. Mastoid sinuses (air cells in the temporal bone) connect to the middle ear, not inner ear, for drainage and pressure, making 'nose: middle ear' correct.
Question 4 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 5 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.
