A

Connective Tissue

33
Q

Characteristic of Connective Tissue

A

Variation in blood supply

A

Collagen Fibers

36
Q

Are very fine, short collagen fibers that branch to form supporting network

A

Reticular Fibers

37
Q

Have structure similar to that of coiled metal bed springs; after being stretched, they can coil to their original shape

42
Q

Consists of relatively few protein fibers that form a lacy netword with numerous spaces filled with ground substance and fluid

A

Loose Connective Tissue

43
Q

3 Subdivision of Loose Connective Tissue

A

Areolar
Adipose
Reticular

44
Q

Fine network of fibers (mostly collagen, some are elastic) w/ spaces between fibers, fibroblasts, macrophages, lymphocytes are located in the spaces

Loose packing, support, nourishment of the structure

Widely distributed throughout the body

A

Areolar Connective Tissue

45
Q

Little extracellular matrix surrounding cell; odipocytes or fat cells, are so full of lipids that the cytoplasm is pushed to the periphery of the cell

Function: Packing material, thermal insulator, energy storage and protection of organs against injury from being bumped jorred

Predominantly located at subcutaneous areas, mesenteries, renal pelves, around kidneys, attached to the surface of the colon, mammary glands, and in loose connective tissue that penetrates into spaces and crevices

A

Adipose Connective Tissue

46
Q

Fine network of reticular fibers irregularly arranged

Function: Provides a superstructive for lymphatic and hemopoietic tissues

Located within the lymph nodes, spleen, bone marrow

A

Reticular Connective Tissue

47
Q

It has relatively large number of protein fibers that form thick bundles and fill nearly all the extracellular space

A

Dense Connective Tissue

48
Q

2 Major Subcategories of Dense Connective Tissue

A

Collagenous and Elastic

49
Q

Matrix composed of collagen fibers running in somewhat the same direction in tendons and ligaments, collagen runs in several direction in the dermis of the skin and in organ capsules

Function: Withstand great pulling forces exerted in the directionon the fiber orientation due to great tensile strength and stretch resistance

Located in tendons (attach muscle to bone) and ligaments (attach bones to each other) ; found also in the dermis of the skin, organ capsule and outer kayer of many blood vessel

A

Dense Regular Collagenous Connective Tissue

50
Q

A

Cartilage

52
Q

3 Types of Cartilage
