0.1 Anatomy And Physiology Flashcards
What are the articulating bones of the:
1) elbow
2) wrist
3) knee
4) ankle
1) humerus, radius, ulna
2) radius, ulna, carples
3) femur, tibia
4) tibia, fibula, talus
What type of joint is the wrist
Condyloid
What type of joint is the shoulder
Ball and socket
What type of joint is the ankle
Hinge
What is the agonist and antagonist of Dorsi flexion in the ankle
Agonist = tibialis anterior
Antagonist = gastrocnemius
Name the 3 hamstrings
Bicep femoris, semi-tendenosis, semi- membranosus
What are the 4 quads
Rectus femoris
Vastus lateralis
Vastus medialis
Vastus intermedius
If the elbow flexes what is the agonist
Bicep brachii
If the wrist extends what is the antagonist
Wrist flexors
What is isometric contraction
When the muscle contracts but stays the same length eg. Rugby scrum
What is concentric contraction
When the muscle shortens under tension .eg. Ankles in plantar flexion during take off in long jump
What is eccentric contraction
When the muscle lengthens under tension, usually when resisting gravity - eg. Downwards phase
Sagittal movement
Divides into left and right
Joint - hinge
Movement - flexion, extension, plantar flexion, Dorsi-flexion
Frontal movement
Divides into front and back
Joint - ball and socket
Movement - abduction, adduction
Give an example of Transverse movement
A gymnast doing a twist in the air
