Understanding Origin and Insertion

The way that muscles move your body is related to where muscles are attached in your body. Each muscle has an “origin”, where it comes from (this is the immovable bone) and an “insertion”, where it goes to (this is the moveable bone). Muscles move bones in the direction of the insertion to origin.

Here is an example:

Pectoralis Major

Origin – Clavicular head – originates on the clavicleSternal – Sternal head – originates on the sternum6 upper rib cartilages

Insertion - Humerus (upper arm)

Function - Flexes and adducts upper arm

Movement – picking up groceries with arm bent and loops of bag are around elbow….The arm is moved upward towards the shoulder.

For the remainder of the body parts listed determine the origin, insertion & function. In addition, name 2 or 3 movements/exercises that would be an example of the way that it moves.

1. Biceps brachii

2. Deltoid

3. Gastrocnemius

4. Gluteus maximus

5. Hamstring group
