60
Q

Where is the metaphysis located?

A

61
Q

How to bones increase in width?

A

Bones increase in width by appositional growth, new bone added from outside onto existing bone

62
Q

How do bones increase in length?

Epithyseal plate gives rise to interstitual bone growth

65
Q

What is the function of a sesamoid bone?

A

Sesamoid bones act as a pulley, increasing the tendons ability to transmit muscular force

66
Q

How are muscles attatched onto bones?

A

Tendons attatch muscles to bones

67
Q

What is the origin of a muscle described as?

A

The origin of a muscle is described as the proximal/superior attatchment or distal/inferior attatchment, origin being the end that does not move

68
Q

What is the insertion of a muscle described as?

Q

Why are the anterior tendons of the abdomen thin and flat?

A

The anterior tendons of the abdoment are thin and flat to allow you to breath

Q

What must skeletal muscles span to exert their action?

A

Skeletal muscles must cross a joint to exert their action, so are attatched by tendons to the bones on both sides of the joint

72
Q

What is flexion?

A

Flexion is pulling two bones together

73
Q

What is extension?

A

Extension is pulling two bones apart
