Study Notes
Skeletal System Functions
- The skeletal system provides a framework for the body, allowing it to maintain its shape and protect internal organs.
Importance of Rigid Skeleton
- A hard and rigid skeletal system is essential for the human body, as it provides support, protection, and enables movement.
Bone Function in Movement
- Bones work in conjunction with muscles to produce movement in the human body.
Hemopoeitic Activity
- The bones in the pelvis, ribs, and sternum have hemopoeitic activity, producing new blood cells.
Muscle Types
- Smooth muscle is found lining the walls of blood vessels and visceral organs.
Skeletal Muscles
- Skeletal muscles are closely associated with connective tissues in the limbs.
Cardiac Muscles
- Cardiac muscles are found in the heart.
Voluntary Muscles
- Skeletal muscles are under voluntary control by the nervous system.
Skeletal System Definition
- The system of bones, associated cartilages, and joints of the human body is called the skeletal system.
Skeletal System Function
- The human skeleton performs the function of supporting and protecting the body, as well as facilitating movement.
