Physiology and Movement (Musculoskeletal System and Analysis of Movement) Flashcards
Types of Joints
1) Fibrous: Allows very little movement
2) Cartilaginous: Allows a limited amount of movement
3) Synovial: Allows for a great deal of movement
Types of Synovial Joint
1) Ball and Socket Joint: Allows movement in every direction and found in shoulder
2) Hinge Joint: Allows movement in only one direction and found in knee and elbow
Three types of Planes
1) Sagittal Plane: Vertical plane which separates body into left and right
2) Frontal Plane: Vertical plane which separates the body into front and back
3) Transverse Plane: Horizontal plane which splits the body into up and down
Axis of Movement
1) Transverse Axis: Runs from side to side like a table football player
2) Sagittal Axis: Goes through the body in the front and come out the back
3) Longitudinal Axis: Runs from top to bottom like a kebab skewer
Combination of planes and axis
1) Sagittal Plane about a transverse axis
2) Frontal Plane about a sagittal axis
3) Transverse plane about a longitudinal axis
Joint action which uses the Sagittal plane about a Transverse axis
1) Flexion
2) Extension
3) Hyper-extension
4) Plantar-flexion and Dorsi-flexion
Joint action which uses the Frontal plane about a Sagittal axis
1) Abduction
2) Adduction
Joint action which uses the Transverse Plane about a Longitudinal axis
1) Horizontal Adduction
2) Horizontal abduction
Agonists and Antagonists
Agonist: Muscle responsible for the movement
Antagonist: Muscle that lengthens and works in opposite
Muscle Contraction
Concentric: The muscle shortens under tension
Eccentric: The muscle lengthens under tension
Isometric: Muscle contracts but no movement occurs
