Musculoskeletal System Flashcards
The musculoskeletal system
consists of the skeletal system (bones and joints) and the skeletal muscle system (voluntary or striated muscle)
Skeletal system and the skeletal muscle system
Work together to protect the internal organs, maintain posture, produce blood cells, store minerals and enable the body to move.
Skeleton
the bones or shell of an animal that support and protect it as well as allowing movement
Bones
the pieces of hard tissue that make up the skeleton of a vertebrate
A joint is
the region where two bones meet
Ligaments are
band of tough tissue that connects the ends of bones or keeps an organ in place
Synovial fluid
the liquid inside the cavity surrounding a joint that helps bones to slide freely over each other
What are the types of joints?
Pivot
Hinge
Ball and socket
Immovable
Pivot joints
joint that allows a twisting movement
Hinge joints
joints in which two bones are connected so that movement occurs in one plane only
Ball and socket joints
joints where the rounded end of one bone fits into the hollow end of another
Immovable joints
joints that allow no movement except when absorbing a hard blow
Tendons are
tough rope-like tissue connecting a muscle to a bone
