Cells in Loose Areolar Connective Tissue |
Fat cell, fibroblast, macrophage, mast cell |
|
|
It is the most widely distributed type of connective tissue |
Loose Areolar Connective Tissue |
|
|
Describe loose Areolar Connective Tissue |
Contains collection of all types of cells Richly supplied with blood vessels, lymphatic vessels, and nerves Flexible but not resistant to stress |
|
|
Connective Tissue fibers in LACT |
Collagen, elastin, reticular |
|
|
Blood vessels in LACT |
Arterioles and venules |
|
|
Distinguishing features that differentiate loose connective tissue from mucous variety |
Loose connective tissue contains differentiated cells while mucous connective tissue has mucoid ground substance containing chondroitin sulfate and hyaluronic acid |
|
|
Purpose of chondroitin sulfate |
Provides strength |
|
|
Purpose of hyaluronic acid |
Provides moisture, makes the tissue soft and elastic |
|
|
Function of loose areolar connective tissue |
Holds organs in place Attaches epithelial tissue to other underlying tissue Reservoir of water and salts for surrounding tissues Where nutrients are obtained and wastes are released |
|
|
Fat-storing cells |
Adipocytes |
|
|
Primary storage site of neutral fats |
Adipose connective tissue |
|
|
Function of adipose connective tissue |
Cushion and keep organ in place Key regulator of body's overall energy metabolism Thermal insulator and shock absorber Richly supplied with blood vessels and nerves |
|
|
Describe Adipose cells |
Relatively large round or oval shaped; connective tissue containing large globules of fat cells |
|
|
Define fat lobules |
Represents a grouping of fat cells enclosed with a small thin membrane and share the same terminal vascular supply |
|
|
Fat globule |
Individual pieces of intracellular fat inside other types of cell |
|
|
Signet ring appearance of fat cell |
Thin rim of cytoplasm with nucleus on its edges |
|
|
It forms a supportive stroma of lymphoid organs, hematopoietic bone marrow and endocrine glands |
Reticular connective tissue |
|
|
It consists of abundant reticular fibers (Type III collagen) arranged in slender bundles |
Reticular connective tissue |
|
|
Modified fibroblast cells allowing cell-lined system |
Reticular fibers |
|
|
Lattice fiberx |
Reticular fiber arranged in slender bundles forming a 3d closed meshed network |
|
|
Argyrophilic fiber |
Because of affinity for silver salts |
|
|
Thick layer beneath the epithelial lining of the stomach and intestine |
Lamina propia |
|
|
Why is dense connective tissue resistant to stress |
Because of the arrangement and orientation of the bundles of collagen fibers |
|
|
Why is dense connective tissue resistant to stress |
Because of the arrangement and orientation of the bundles of collagen fibers |
|
|
Location where dense irregular connective tissue is found |
Fasciae Reticular region of the dermis of the skin Periosteum of the bone Membrane capsule around kidney, liver, testes, lymph nodes and heart valves |
|
|
Its collagen fibers forms unaligned three dimensional meshwork |
Dense irregular connective tissue |
|
|
Describe the ground substance of LACT |
Relatively fluid, semi-fluid, gelatinous moderate amount of ground substance with cells more abundant than fibers |
|
|
Prominent fibers in LACT |
Collagen fibers predominate but elastin and reticular are also present |
|
|
Argyrophilic fiber |
Because of affinity for silver salts |
|
|
A part of a tissue or organ with supportive or structural role |
Stroma |
|
|
Function of reticular connective tissue |
Provide structural support in lymphoid organs forming a meshed network where cells and fibers are kept |
|
|
A metal impregnation technique where ammoniacal silver bind to tissue of interest |
Reticular Stain Kit |
