61
How to bones increase in width?
Bones increase in width by appositional growth, new bone added from outside onto existing bone
62
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

64
What tissue gives rise to interstitual bone growth?
Epithyseal plate gives rise to interstitual bone growth
65
What is the function of a sesamoid bone?
Sesamoid bones act as a pulley, increasing the tendons ability to transmit muscular force
66
How are muscles attatched onto bones?
Tendons attatch muscles to bones
67
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
68
What is the insertion of a muscle described as?
The insertion of a muscle is described as the distal/inferior./lateral attatchment, being the moving end of the muscle
69

The anterior tendons of the abdomen are thin and flat
70
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
