19
Q

Function to attach muscle to bone, and when stretched to store elastic energy that contributes to movement.

A

Tendon

20
Q

Tendon allows the ____ to be an optimal distance from the joint.

A

Muscle belly

21
Q

Tendon collagen fibers:

A

Type 1: 95%

Type 3&4: 5%

22
Q

Tendon vascularity rate:

A

Tendons

37
Q

3 sections of a tendon:

A
  • Bone-tendon junction
  • Tendon midsubstance

39
Q

What section of tendon, physical junction between the tendon and bone is referred to as the enthesis?

A

What section of tendon, absorbs and distributes the stress concentration over a broader area?

A

Bone-Tendon Junction

42
Q
