Which glands have the most important role in maintaining constant core temperature?

Rationale:
A. Phalanges are the bones of the fingers and toes and articulate with adjacent bones in the hands and feet.
B. Hyoid is a U-shaped bone located in the anterior neck that does not directly articulate with any other bone. Instead, it is anchored by muscles and ligaments, providing support for the tongue and serving as an attachment point for muscles involved in swallowing and speech.
C. Patella is the kneecap and articulates with the femur, forming part of the knee joint.
D. Occipital is a cranial bone that articulates with the parietal and temporal bones and forms part of the skull base.

Rationale:
A. Humerus is the long bone of the upper arm, extending from the shoulder to the elbow. While it is long and strong, it is not the longest bone in the body.
B. Ulna is one of the two forearm bones, located on the medial side (little finger side). It is relatively slender and much shorter than the femur.
C. Known as the shin bone, it is the second longest bone in the body and bears most of the body’s weight in the lower leg. However, it is still shorter than the femur.
D. The femur, or thigh bone, extends from the hip to the knee and is the longest, strongest, and heaviest bone in the human body. It supports much of the body’s weight, allows locomotion, and provides attachment points for many large muscles.
