Connective Tissues

Question 1

What are the properties of collagen fibers and their function?

Answer 1

Their properties are inextensibility and tensile strength, they exist due to Straiton and crimps(Have a limited extension of only 3%)
Their function include resisting stretch and inextensibility.

Question 2

What are the structures related to personal training?

Answer 2

Fasciae, tendons and ligaments

Question 3

What is the function of a tendon? What happens if you stretch a tendon too much?

Answer 3

They transmit force from muscle to bone to produce movement. Tendons deform when a stretch force is applied. This is called a load deformation curve. Stretching the tendon beyond its yield point will cause permanent length changes and structural integrity.

Question 4

What is the function of ligaments? What do they consist of and why?

Answer 4

Ligaments attach bone to bone. They consists of a greater mixture of elastic and collagen fibers woven together. Hence giving ligaments a pliant and flexible structure but a strong, defensive and inextensible against forces.

Question 5

What is the relative contribution of soft tissues to the total resistance of joint movement?

Answer 5

Joint capsules - 47%
Muscle(Fascia) - 41%
Tendons - 10%
Skin - 2%
