Q

What are the characters of loose connective tissue?

A

οƒœ It binds tissues and organs together.

οƒœ It carries blood vessels, lymphatics and nerves.

οƒœ Called areolar as the matrix shows false cavities called areolae.

οƒœ Called ordinary as it is widely distributed all over the body; found around blood vessels, in the submucosa of the digestive organs and in the serous membranes e.g. peritoneum.

Q

What is the structure of white adipose connective tissue?

A
  • Lobules of White adipocytes separated by loose C.T.
  • with less capillary supply than the brown type.

Q

What are the functions of white adipose connective tissue?

A
  • Energy depot (Storage of fat).
  • Heat insulation.
  • Gives contour to the body.
  • Support organs e.g. kidney.
  • Cushions during seating.

Q

What is the color of brown adipose connective tissue?

A

Brown due to:

  1. cytochromes in its much mitochondria
  2. Blood color in its rich capillary supply.

Q

What are the sites of reticular connective tissue?

A
  • Stroma of parenchymatous organs e.g. liver, spleen and lymph nodes.
  • Reticular lamina of the basement membranes
17
Q

What is the structure of reticular connective tissue?

A

Formed of reticular cells and fibers that form a network.

18
Q

what is the staining of reticular connective tissue?

A

Silver stain→ brown to black

19
Q

What are the sites of regular type of white fibrous connective tissue?

A

tendons and cornea of the eye.

20
Q

What is the structure of the regular type of white fibrous connective tissue?

A
  • Parallel collagenous bundles.
  • Fibroblasts (tendon cells, corneal corpuscles): the cells have thin nuclei and the cytoplasm is not apparent.
21
Q

what are the sites of the irregular type of white fibrous connective tissue?

A

sclera of the eye, capsule of organs and outer fibrous layer of the periosteum & perichondrium.

22
Q

What is the structure of the irregular type of white fibrous connective tissue?

A
  • Irregular collagenous bundles.
  • Fibroblasts or fibrocytes between the bundles.
23
Q

What are the stains used for white fibrous connective tissue?

β€œBoth regular and irregular”

A

Hx & E β†’ Acidophilic

Van Gieson’s stain β†’ red

Mallory trichrome stain→ blue

24
Q

What are the sites of mucoid connective tissue?

A
  • Wharton’s jelly of the umbilical cord.
  • Vitreous body of the eye.
  • Pulp of the teeth.
25
Q

What is the structure of mucoid connective tissue?

A
  • The matrix is soft as it is rich in mucin and hyaluronic acid.
  • UMCs or young fibroblasts (mucinous cells) with long processes which intercommunicate with those of the neighboring cells.
26
Q

What are the functions of connective tissues?

A
