if the nerve affected doesnt affect the cell body

Question 13

factors affecting dysfunction in soft tissue

Answer 13

1. scar formation
2. limitation of lymphatic circulation and swelling
3. ground substance dehydration and intermolecular cross link

Question 14

functions of fascia

Answer 14

1. serves as a lubricant to allow movement and form and structure of the body
2. supports the nerves and vessels
3. allows muscles to move over one another
4. participating in reflex loops
5. contracting and relaxing to respond to deformation

Question 15

what is the deepest layer of the fascia

Answer 15

duramatar

Question 16

what happens to the body after trauma

Answer 16

collagen becomes dense then fibrosis takes place 
elastin loses its resiliency 
exessive cross links 
decreased synthesis of GAG 
dehydration occurs

Answer 17

it may produce local or refered pain
