chapter 6: tendons

Question 1

Tendons function is what?

Answer 1

mechanically attach muscle to bone or other muscle

to transmit the muscle contraction force

Question 2

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

Answer 2

some elastic fibers and some reticular fibers.

Question 3

What composes the structure of tendons

Answer 3

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

Question 4

Fibrocytes can also be called what in tendons

Answer 4

tenocytes or tendinocytes

Question 5

Vascularity is limited but which part of the tendon has more

Answer 5

the ends

Question 6

What are the three CT layers associated with tendons

Answer 6

endotendineum, epitendineum and peritendineum

Question 7

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

Answer 7

collagen I bundels

Question 8

Endotendineum is or is not vascular

Answer 8

it is

Question 9

endotendineum does or does not have nerves present?

Answer 9

it does

Question 10

endotendineum has how many cell types?

Answer 10

multiple cell types

Question 11

epitendineum is another thin layer of CT that surrounds what?

Answer 11

the entire tendon

Question 12

Is the epitendineum or the endotendineum more fibrous

Answer 12

epitendineum

Question 13

what are the two major layers of the CT layers

Answer 13

endotendineum and epitendineum

Question 14

The peritendineum is a sheath of what?

Answer 14

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

Question 15

what is the function of the CT layers

Answer 15

1. provides mechanical connection to muscle CT layers

2. offers repair potential from CT sites

Question 16

Golgi tendon organ is also known as what?

Answer 16

neurotendinous spindles

Question 17

what is the location of the Golgi tendon organ?

Answer 17

junction of tendons and muscles

Question 18

Golgi tendon organs are composed of what

Answer 18

collagen fibers and free nerve endings

Question 19

what is the function of Golgi tendon organs?

Answer 19

monitor force of the muscle contraction

Question 20

Sharpey’s fibers are bundles of what?

Answer 20

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

Question 21

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

Answer 21

it takes a long time

Question 22

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

Answer 22

about a hundred days

Question 23

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

Answer 23

several months

Question 24

what can develop during the healing process

Answer 24

fibrous adhesions

what helps prevent fibrous adhesion from occurring

Answer 26

physical therapy
