How to bones increase in width?
Bones increase in width by appositional growth, new bone added from outside onto existing bone
How do bones increase in length?
Bones increase in length by interstitual growth, occuring by cell division in the epithyseal growth plate within the bone

Epithyseal plate gives rise to interstitual bone growth
What is the function of a sesamoid bone?
Sesamoid bones act as a pulley, increasing the tendons ability to transmit muscular force
How are muscles attatched onto bones?
Tendons attatch muscles to bones
What is the origin of a muscle described as?
The origin of a muscle is described as the proximal/superior attatchment or distal/inferior attatchment, origin being the end that does not move

The insertion of a muscle is described as the distal/inferior./lateral attatchment, being the moving end of the muscle
How would you describe the anterior tendons of the abdomen?
The anterior tendons of the abdomen are thin and flat
Why are the anterior tendons of the abdomen thin and flat?
The anterior tendons of the abdoment are thin and flat to allow you to breath
What must skeletal muscles span to exert their action?
Skeletal muscles must cross a joint to exert their action, so are attatched by tendons to the bones on both sides of the joint
What is flexion?
Flexion is pulling two bones together
What is extension?
Extension is pulling two bones apart
What do muscles do?
Muscles pull bones together or pull bones apart, they do not push
