Aerolar + Adipose
What type of cells are found in the aerolar c.t. ?
Fibroblasts (makes the fibers)
Macrophages (janitor cells)
Plasma cells (antibodies)
Mast cells (heparin, histamine)
How can you tell the difference between Dense Regular Connective Tissues and Muscle Connective Tissues when viewing in a microscope?
The nuclea of the fibroblast present between the collagen fibers of the Dense Recular C.T.
What is another name for Dense connective tissues?
Fibrosis connective tissues
What are tendons?
cords that attach muscle to bone
What is aponeuroses?
Tendons that are sheetlike; attach muscles to muscles and to bones.
What type of connective tissue forms capsules around certain organs? List examples.

Ligament connecting the verebrea
Lung Tissue
Places where elasticity would be important.
Collagen Fibers are also called ________.
White Fibers
What is known as the fiber of strength?
Collagen Fibers
Delicate, branched, collagen + carbohydrate, continuation of collegen fiber; allow more give than collagen fibers.
Reticular fibers
Yellow fibers-branched; protein elastin; strength and elasticity. Provides stretch.
Elastic fibers
Hyaluronic acide; viscous (part of the intercelluar substance (matrix)

Tissue most widely distributed throughout the body and serves a kind of universal packing material.
Aerolar C.T.
Tissue that is present in all mucous membranes as the lamina propria,
Aerolar C.T.
What is found in the ground substance of cartilage?
chondroitin sulfate, hyaluronic acid, firmly bound collagen fibers, and elastic fibers (in some cases)
shark's skeleton
Where does cartilage receive it's nourishment from ?
by diffusion from blood vessels located in the perichondrium surronding it.
peri = around

glass, gristle
Chondrocytes account for ____% of the cartilage volume?
Widely distributed under epithelia of body. Forms lamina propria of mucous membranes; packages organs; surrounds capillaries.
Connective tissue proper
Loose Connective tissue
Wraps and cushions organs; its macrophages phagocytize bacteria; plays important role in inflammation; holds and conveys tissue fluids.
Aerolar Loose C.T.
smooth muscle is also called
visceral organ

Simple squamous epethelium lining the inside of blood vessels is called...
Single layer of flattened cells with disc-shaped central nuclei and sparse cytoplasm.
Simple squamous
Function: Allows passage of materials by diffusion and filtration in sites where protection is not important; secretes lubricating substances in serosea.
Simple Squamous
Location: Kidney gloeruli; air sacs of lungs; lining of heart, blood vessels, and lymphatic vessels; lining of ventral body cavity (serosea)
Simple Squamous
Single layer of simple squamous cells that line the waslls of the heart, blood vessels, and lymphatic vessels
