Questions for Skeletal System Questions
Question 1 of 5
The epiphyses are covered with to provide protection.
Correct Answer: A
Rationale: The epiphyses of long bones are covered with articular (hyaline) cartilage at joints, reducing friction and protecting bone ends during movement. Red and yellow marrow are inside bones, and the endosteum lines the medullary cavity, making 'articular (hyaline) cartilage' correct.
Question 2 of 5
The process of endochondral ossification uses a model of to form bones.
Correct Answer: B
Rationale: Endochondral ossification forms bones (e.g., long bones) from a hyaline cartilage model, which ossifies over time. Fibrocartilage is in joints, fibrous membranes are for intramembranous ossification, and adipose is fat, making 'hyaline cartilage' correct.
Question 3 of 5
Identify the four paranasal sinuses associated with the skull.
Correct Answer: D
Rationale: The paranasal sinuses are frontal (forehead), maxillary (cheek), sphenoidal (behind eyes), and ethmoidal (between eyes), all skull-related. Temporal and mastoid are not sinuses, mandibular is the jaw, making 'frontal, maxillary, sphenoidal and ethmoidal' correct.
Question 4 of 5
The hard palate is formed by the and bones.
Correct Answer: B
Rationale: The hard palate, the mouth’s roof, is formed by the maxillae (anterior) and palatine bones (posterior). The mandible is the lower jaw, zygomatic the cheek, and vomer the nasal septum, making 'maxillae: palatine' correct.
Question 5 of 5
What is the name of the U-shaped bone located superior to the larynx?
Correct Answer: A
Rationale: The hyoid, a U-shaped bone in the neck above the larynx, supports the tongue and lacks articulation with other bones. The thyroid is cartilage, zygomatic arch is facial, and clavicle is pectoral, making 'hyoid' correct.
