The musculoskeletal system is made up of the body’s bones (the skeleton), muscles, cartilage, tendons, ligaments, joints, and other connective tissue that support and bind tissues and organs together. The skeleton serves as the main storage system for calcium and phosphorus.
What are 6 main functions of the skeletal system?
It is composed of 270 bones at birth and decreases to 206 bones by adulthood after some bones have fused together. The human skeleton serves six major functions: support, movement, protection, production of blood cells, storage of ions, and endocrine regulation .
What are the 6 functions of the skeletal system quizlet?
The six main functions of the skeletal system are: Support, protection, assistance in movement, mineral homeostasis (storage and release) , blood cell production (red bone marrow) and triglyceride storage (yellow bone marrow).
What are the main parts of a skeleton?
The skeleton is traditionally divided into two major parts: the axial skeleton and the appendicular skeleton , both of which are pictured in Figure 14.2. 3. The axial skeleton forms the axis of the body. It includes the skull, vertebral column (spine), and rib cage.

What are the functions of the skeleton quizlet?
The five important functions of the skeletal system are support, protection, movement, mineral storage, and blood cell formation . Without our skeleton, our bodies would have no definite shape. The skeleton protects the internal organs.
What is the relationship between muscle function and bones?
Muscles keep bones in place and also play a role in the movement of bones. To allow motion, different bones are connected by joints. Cartilage prevents the bone ends from rubbing directly onto each other. Muscles contract to move the bone attached at the joint .
