21
Q

Whhere does dorsi-flexion occur?

A

Ankle

22
Q

Where does plantar felxion occur?

A

Ankle

23
Q

Pivot joint example

A

Atkas and axis at the top of the cervical vertebrae alows the head to move.

24
Q

Hinge joint example

A

Elbow with ulna and humerus

Back and forth rotation

25
Q

Ball and socket joint example?

A

The hip:a Ball sits inside a cup shape hole with cartalidge.

-alouds a range of movement

26
Q

Condolyoid example

A

Wrist, enables some movements

27
Q

What are ligaments?

Def

A

Esastic fibres that join one bone to another

Usually to hood things together and keep them stable. They keep your skeleton supported whilst allowing movement

28
Q

What are tendons?

Def

A

Non-elastic fibres that attach muscle to bone

Tendons let you apply power and movement. Tendons grow in strength the more you use them.

29
Q

What is the onotomic position?

A

When the skeleton is tandong up with its hands out to the side.

Classic skeleton image on Showbie

30
Q

How does the hinge joint work in the knee?

A

In the knee joint, the tibia is hinged on the femur so the leg can be ben (flexion) or straightened(extension)

31
Q

How does the hinge joint work in the elbow?

A

A hinge joint between the humerus and the ulna which enables us to bend(flextion) or straighten(extention) the arm.

(Bicep curls)

The muscle that flex the joint is on the front(bicep) and thr muscle that extends on thr back(triceps)

32
Q

How does the hinge joint work on the ankle?

A

Enables us to bend the foot up(dorsi-flexion)

To point the toes down(plantar flexion)

33
Q

What is a condyloid joint?(definition)

A

Similar to ball and socket but the ball rests at the end of a bone rather than inside the socket-allows circular motion

34
Q

Example of condyloid joint?

A

Wrist
