15Via Tendons. Tendons join the voluntary muscles to the skeleton. When the muscle contracts, the tendon pulls on the bone it is attached to and moves the bone.
16Where do they attach? Each muscle has an ORIGIN and an INSERTION. The origin is where the tendon of a muscle is anchored to a fixed point on the skeleton.The insertion is where the tendon is attached to the bone we want to move.
17E.g – Biceps & triceps action: Origin of bicep –The top of the scapulaThe glenoid cavity (in the shoulder).Insertion of bicep –Near the elbow, in the radius.
19Turn to page 26 in your text books. Use it to help you label the origin, insertion & muscles on the diagrams.Stick these in your work books underneath the definitions of a tendon, origin & insertion.
21To complete the sheet about muscles, how they move & how they are attached. To be completed over the xmas holidays & brought into the 1st lesson back.Don’t forget – a quick test that 1st lesson – so use it to help with revision!
