1
Q

Tendons function is what?

A

mechanically attach muscle to bone or other muscle

to transmit the muscle contraction force

2
Q

Tendons are primarily collagen (95-99%) but also what fibers?

A

some elastic fibers and some reticular fibers.

3
Q

What composes the structure of tendons

A

collagen, minimal ground subject, fibrocytes, vascularity, and associated CT layers

4
Q

Fibrocytes can also be called what in tendons

A

tenocytes or tendinocytes

5
Q

Vascularity is limited but which part of the tendon has more

A

the ends

6
Q

What are the three CT layers associated with tendons

A

endotendineum, epitendineum and peritendineum

7
Q

Endotendineum is a thin layer of CT that is surrounded by what?

A

collagen I bundels

8
Q

Endotendineum is or is not vascular

A

it is

9
Q

endotendineum does or does not have nerves present?

A

it does

10
Q

endotendineum has how many cell types?

A

multiple cell types

11
Q

epitendineum is another thin layer of CT that surrounds what?

A

the entire tendon

12
Q

Is the epitendineum or the endotendineum more fibrous

A

epitendineum

13
Q

what are the two major layers of the CT layers

A

endotendineum and epitendineum

14
Q

The peritendineum is a sheath of what?

A

a sheath of fibrous CT investing a fiber bundle of a tendon

15
Q

what is the function of the CT layers

A
  1. provides mechanical connection to muscle CT layers

2. offers repair potential from CT sites

16
Q

Golgi tendon organ is also known as what?

A

neurotendinous spindles

17
Q

what is the location of the Golgi tendon organ?

A

junction of tendons and muscles

18
Q

Golgi tendon organs are composed of what

A

collagen fibers and free nerve endings

19
Q

what is the function of Golgi tendon organs?

A

monitor force of the muscle contraction

20
Q

Sharpey’s fibers are bundles of what?

A

collagen I that extends from tendon into the periosteum and/or bony matrix

21
Q

Tendons are very strong but once injured how long does it take to repair?

A

it takes a long time

22
Q

How one does it usually take to make new collagen I fibers?

A

about a hundred days

23
Q

how long does it take to make enough collagen I to repair an injury

A

several months

24
Q

what can develop during the healing process

A

fibrous adhesions

25
Q

what are some current treatments for tendon repair

A
  1. rest is the best (time)
  2. physical therapy
  3. ice
  4. braces and other support
  5. cold laser
  6. chirocare
26
Q

what helps prevent fibrous adhesion from occurring

A

physical therapy
