Q

Fibers

A

Provide support
• collagen - cross linked in matrix e/ extreme length
• elastic - cooled w/ ability to stretch & recoil
• reticular - fine collagenous fibers continuous w/ collagen; forms network between connective tissue & other tissue types

Q

Mesenchyme

A

Embryonic
First tissue type to develop
Composed of star shaped cells & fluid ground surface
Differentiates into all other connective tissues

Q

Areolar loose connective tissue proper

A

Semi fluid ground substance where all 3 fiber types are dispersed
Fibers are most distinct feature
Serves as packing material between other tissues

Q

Adipose loose connective tissue proper

A

Fat cells
Insulates and protects body organs
Reserves energy fuel

17
Q

Reticular loose connective tissue proper

A

Finely woven reticular fibers in soft ground substance

Forms internal framework that can support free blood cells in spleen and bone marrow

18
Q

Cartilage

A

Tough but flexible

Avascular w/ no nerve fibers

19
Q

Chondroblasts production in cartilage

A
  • Intersistial growth - cartilage formation from w/in

* appositional growth - cartilage formation on superficial face of cartilage structure

20
Q

Hyaline cartilage

A

Most abundant in body
Contains large numbers of collagen fibers, though not apparent
Provides firm support w/ some pliability

21
Q

Elastic cartilage

A

Nearly identical to hyaline but more elastic & tolerance for bending

22
Q

Fibrocartilage

A

Coarse, parallel collagen fibers
Provides support w/ compressibility
Intervertebral discs & knee cartilage

23
Q

Bone

A

Osteo tissue

Consists of firm, collagen containing matrix embedded w/ calcium salts (offer rigidity)

24
Q

Blood

A

Most atypical connective tissue

Contains cells surrounded by no living fluid matrix: blood plasma
