Teeth are found in the

Correct Answer: A

Rationale: Teeth are embedded in the maxillae (upper jaw) and mandible (lower jaw) only. The palatine bones form the hard palate but do not house teeth.

Correct Answer: D

Rationale: The pituitary gland sits in the sella turcica, a depression in the sphenoid bone. Surgery (e.g., transsphenoidal) targets this area, not the mastoid, pterygoid, or styloid processes.

Correct Answer: A

Rationale: The pinna (external ear) in mammals is supported by elastic cartilage, which provides flexibility and resilience to maintain its shape. Hyaline cartilage is rigid (e.g., nose), white fibrous tissue is dense (e.g., tendons), and calcified cartilage is hardened—elastic cartilage is uniquely suited for the pinna.

Correct Answer: B

Rationale: The femur (thigh bone) is the longest and strongest bone in the human body, supporting significant weight and muscle forces during movement. The cranium is a collection of bones, not a single bone, while the tibia and radius are shorter and less robust.

Correct Answer: C

Rationale: Carpals (wrist bones) are short bones, cuboidal in shape, providing stability and limited movement. The femur and radius are long bones, and the cranium comprises flat and irregular bones, not short ones.
