Skeletal System：練習問題

What is the primary physiological function of yellow bone marrow found within the medullary cavity of long bones in adults?

A synovial joint that allows movement in three planes (sagittal, frontal, and transverse) is described as triaxial. Which joint in the human body fits this classification?

The patella is crucial for knee extension. From a biomechanical perspective, how does this bone enhance the function of the skeletal system during a vertical jump?

Which of the following joints is an example of a hinge joint?

Which structure within a synovial joint is responsible for secreting the fluid that reduces friction and provides nutrients to the articular cartilage?

Name the two main divisions of the human skeletal system.

Describe the function of articular cartilage in a synovial joint and explain how its structural properties help protect the underlying bone during high-impact sports.

Explain the mechanostat theory in bone biology and how it determines the threshold for bone adaptation when an athlete increases their resistance training intensity.

The human skeletal system contains bones of different shapes and sizes to support various physical activities.
(a) Classify the carpals (found in the wrist) and the scapula (shoulder blade) according to their bone shape categories.
(b) State one primary function of flat bones in the human body other than providing a large surface area for muscle attachment.

A synovial joint is designed to facilitate movement while protecting the skeletal system. (a) State the functions of the articular cartilage and synovial fluid. (b) Explain how ligaments differ from tendons in terms of their structural role in joint stability during a sudden change of direction in soccer.
