Question 13

Whats joint loading

Answer 13

force on the tissues of the joints, like menisci, which compresses them forcing them to absorb nutrients.

resist compression and tension

Question 21

function of hyaline cartilage

Answer 21

resist compression

Question 22

two examples of fibrous joint

Answer 22

sutures and distal tibiofibular joint. As this fibrous is why we can supinate these bones, they must provide more support

Question 23

structure of ligaments

Answer 23

have high elastin which allows them to stretch and recoil,. They can keep the bone where its meant to be easily for this fact. DFCT, collagen aussi

Question 24

structure of tendons

Answer 24

As fibres are alinged in these structures they resist tension well. little elastin more collagen

Question 25

Ligaments and tendons are made of what generally

Answer 25

dense fibrous connective tissue. Made of collagen and elastin, hardly any ground substance, instead they are mostly cartilage.

Question 26

what kinds of cells work in DFCT

Fibroblasts make the DFCT and fibroblasts destroy it.

intracapsular ligaments

Question 30
