16
Q

Simple Epithelia?

A

Provides Little Protection to the Underlying Connective Tissues. Found in Protected Areas such as Internal Compartments, Ducts, Vessels, and Passageways.

17
Q

Stratified Epithelia?

A

Thicker and Stronger, Subjected to Mechanical and Chemical Stress.

18
Q

Stratified Squamous Epithelium?

A

Cuboidal Cells are visible near the Basement Membrane. Squamous Cells are Found Near the Luminal Surface. Altogether, Is call Stratified Squamous.

19
Q

Simple Squamous Epithelia?

A

Delicate and Thin. Lining Passages Involving Gases or Liquids.

20
Q

Simple Cuboidal Epithelium?

A

A Single Layer of Cubic Cells. Provides Little Protection from abrasion. Is Found in Areas of Secretion and Absorption.

21
Q

Simple Columnar Epithelia?

A

Elongated and Closely Packed Together. Lines the Length of the Gastrointestinal Tract. Found in Many Excretory Ducts.

22
Q

Stratified Cuboidal Epithelium?

A

Two Layers of Cuboidal Layers. Found in Large Excretory Ducts.

23
Q

What is Connective Tissues Composed of?

A

Extracellular Fibers, Ground Substance, and Cells

24
Q

What is Ground Substance?

A

Amorphous, Homogenous Material. Can be a Liquid, a Gel, or a Calcified Solid.
Composed of Unbranched Chains of Glycoproteins Called Glycosaminoglycans.

25
Q

What are Collagenous Fibers?

A

Strong, Thick Strands Composed of Structural Protein Collagen. Possess Tremendous Tensile Strength.

26
Q

What are Reticular Fibers?

A

Thin, Delicate Collagenous Fibers. Provides Support for Highly Cellular Organs.

27
Q

What are Elastic Fibers?

A

Composed of Protein Elastin. Branched and Form Complex Networks (Like Reticular Fibers). Found in Tissues Subjected to Stretching.

28
Q

What is a Fibroblast?

A

Large, Irregularly Shaped Cells that Manufacture and Secrete Both the Fibers and Ground Substance.

29
Q

What are Reticular Cells?

A

Flat, Star-Shaped Cells. Involved in the Immune Response.

30
Q

What is Fat?

A

Adipose Tissue.

31
Q

Where is White Adipose Tissue?

A

Found Throughout the Body, Especially Deep Layers of the Skin.

32
Q

Where is Brown Adipose Tissue?

A

Found in Newborn Animals and in Animals that Hibernate During the Winter.

33
Q

What is the Reticular Connective Tissue?

A

Composed of a Complex, Three-Dimensional Network of Thin Reticular Fibers. Forms a Stroma.

34
Q

What is the Stroma?

A

A Framework Formed by Reticular Connective Tissue. Forms Several Organs.

35
Q

What is the Perichondrium?

A

Gives Nutrition to the Cartilage as a Surrounding Membrane.

36
Q

What is the Hyaline Cartilage?

A

Most Common Type of Cartilage.

37
Q

What is the Elastic Cartilage?

A

Contains Elastic Fibers.

38
Q

What is the Haversian Canal?

A

Supports the passage of Blood Vessels.
