Flashcards in Physiology Quiz 2 Deck (24):
1

What is a fascicule?

Group of collagen fibers

2

What forms a tendon?

Group of fascicles

3

What surrounds fascicles?

Loose connective tissue

4

What surrounds tendons?

Dense irregular tissue

5

What covers tendons that allows movement?

Epitendineum

6

What is the synovial sheath?

Found where tendon passes through joint cavity or narrow space.

7

What do tenocytes and fibroblasts do for the tendon?

Helps repair tendons in a slow process because of the lack of blood vessels.

8

What is a tendon?

Dense connective tissue from bone to bone that deal with tensile forces.

9

What is missing from tendons?

Loose connective tissue or specialized fibroblasts

10

What are sharpey's fibers?

Fibers that penetrate the bone from the periosteum

11

What are the functions of tendons?

Hold bones and stabilize joints

12

What is retinacula?

Straps of dense regular connective tissue

13

What is cartilage?

Semi-rigid connective tissue with high amount of fibers that deal in compressive forces (weight bearing).

14

How is the cartilage matrix made?

Secreted by chondroblasts and maintained by chondrocytes

15

What is the matrix made of?

Hyaluronic acid and chondroitin sulfate and no blood supply

16

What covers the matrix?

The perichondrium (Type I)

17

What are the types of cartilage?

Hyaline, elastic, fibrocartilage

18

What are the characteristics of hyaline cartilage?

- Body's most prevalent

19

What are the characteristics of elastic cartilage?

- Intermediate elasticity

20

What are the characteristics of fibrocartilage?

- Least rigid

21

What are the three stages of cartilage growth?

- Interstitial

22

What is interstitial growth?

Chondrocytes in the lacunae have cell division

23

What is appositional growth?

Chondroblasts in inner periosteum adds new layers of matrix that continues until puberty

24

What is repair damage?

Resembles appositional growth
