Muscle Histology
Part Structure Function
In this lab you will be observing several histology slides of the muscular system. Predict what you might expect to see. Describe the structure of the tissue type and the function it performs. Do your best to draw as much detail as possible and label what you can.

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
6. Latissimus dorsi
7. Rectus abdominis
8. Sartorius
