Skeletal And Musculat Systems Flashcards
Skeletal system
Body support
Muscular system
Movement
The skeletal system is composed of what
Connective tissues
Functions of the skeletal system
Support and shape, protection of organs, hematopoiesis, and mineral storage
Types of skeletons
Hydrostatic, external, internal
Hydrostatic skeleton
 composed of fluid, held under pressor in the closed body cavity also shapes and supports the body
External skeleton
Outside protection
Internal skeleton
Inside prodtection
Axial
Division of the vertebrate skeleton that acts solely in protection
Appendicular
Division of the vertebrate skeleton that supports the paired appendages
Diaphysis
Middle bone structure made of compact bone
Epithysis
End of the bone structure that is composed of spongy bone
Epiphyseal line
Region of bone elongation between the epiphysis and diaphysis
Red marrow
Found in spongy bone cavities of long bones and its main function is hematopoiesis (blood cell production)
Yellow marrow
Found in shaft cavities and serve as fat stories
Types of joints
Fibrous, cartilaginous, and synovial
Fibrous joints
Immovable joints
Cartilaginous joints
Slightly movable joints
Synovial joints
Freely movable joints
Types of synovial joints
Ball and socket joints, hinge joints, and pivot joint
Ball and socket joints
Allow for great rains of motion in several planes
Hinge joints
Provides movement and only one plane
Pivot joint
Allows rotational movement
Muscle is made up of proteins called
Actin and myosin
Smooth muscle tissue
Involuntary tissue that surrounds internal organs
Cardiac muscle tissue
Involuntary tissue found only in walls of the heart
Skeletal muscle tissue
Voluntary tissue that make up the muscles attached to the bones
