Anatomy n Physiology Flashcards
what are isotonic contractions
they occur when the muscle changes length when it contracts and they result in limb movement
what are isotonic CONCENTRIC contractions
where the muscle contracts and shortens (e.g : bicep curls when bending the elbow from straight to fully flexed- contraction of bicep)
what are isotonic ECCENTRIC contractions
where the muscle contracts and lengthens usually in the downwards phase of a movement (e.g downward phase of a press up the tricep contracts eccentrically to slow movement)
what are isometric contractions
they occurs when the muscle stays the same length. the muscles are working to keep the join stationary.
(e.g handstand)
synovial joint
Type of joint commonly found in limbs containing a synovial membrane that produces synovial fluid.
ligaments
bone to bone
tendons
muscle to bone
what does the synovial fluid do
Is produced to lubricate bones, when example, lunging to reduce friction between bones in badminton
hinge joint
joint that allows flexion and extension
ball and socket joint
Joint that allows many movements, example, flexion and extension, abduction and adduction, rotation and circumduction
musculoskeletal system
The name used to describe the muscular and skeletal system working together
Function of the skeleton
- support (rigid/ solid - keep us upright
- protection of vital organs
- movements
- structure
- mineral storage
- blood cell production
