Musculoskeletal system
Agonists and Antagonists
Joint cannot move by itself it needs muscles to contract and relax
Muscle responsible for causing movement is said to be agonist
Muscle working in opposite to agonist is antagonist
Planes and axis
Frontal plane
Front and back halves
Transverse plane
Upper and lower
Sagittal plane
Left and right halves
Axis
Transverse axis
Side to side
Sagittal axis
Front to Back
Longitudinal axis
Top to bottom
Joint action in SP and TA
Flexion
Extension
Hyperextension
Joint action in FP and SA
Abduction
Adduction
Joint action in TP and LA
Horizontal abduction
Horizontal adduction
Types of joint
Main two types of synovial joint
Hinge joint
Only allows movement in one direction
Due to shape of bones making up the joint
Ball and Socket
Allows movement in every direction
round head of one bone fitting into cup shaped capsule of connecting bone
Articulating bones are the bones that move and meet at a joint
Levers for bones allowing movement
Classified by how much movement can occur
Cartilaginous
Slightly moveable
Synovial
Freely moveable
Fibrous
Fixed
Types of muscular contraction
Isotonic
Eccentric
Muscle lengthening under tension
Lowering phase of bicep curl
Concentric
Muscle shortening under tension
Bicep curl
Isometric
Muscle contracting without length changing so no movement occurs
