THE CONNECTIVE TISSUE
By: Subhan Mahmood, Brad Tolan, Carol Yaracz, Julio Alvarado
General Characteristics
Connective tissue is the most abundant tissue in your body.
They provide protection, support, framework, fills space, stores fat, produces blood cells, fights infection, and helps repair tissue.
They are composed of more scattered cells with abundant intercellular material matrix.
Most connective tissue have a good blood supply
Connective tissue is made up of a ground substance (fluid, and semi-solid) and fibers
Common Types of Cells
Mast cells (prevents blood clots)
Fibroblasts (most abundant, produces fibers)
Macrophages (Phagocytic)
Main types of Fibers
Collagenous Fibers – are thick, made of protein collagen, major structural protein in the body, strong, flexible, not very elastic, appear in long parallel bundles, is known as white fibers.
Elastic Fibers – not as strong , but very elastic (respiratory and vocal cords)
Elastic Fibers and collagenous fibers
Categories of Connective
Loose C.T. Adipose Tissue
(Fat) Dense C.T. (Fibrous
Tissue) Cartilage -Hyaline -Elastic -Fibrocartilage
Bone tissue Blood Tissue Reticular
Loose Connective Tissue
The Loose Connective Tissue binds skin to underlying organs and organs to organs. It also fills in spaces between muscles throughout the body.
Dense Connective Tissue
Fibrous Tissue Closely packed. It also has thick,
collagenous fibers and fine network of elastic fibers.
Includes tendons and ligaments.
Cartilage
All cartilage cells are called Chondrocytes.
o Hyaline- covers end of bones and joints.
o Elastic- external ear and larynx
o Fibrocartilage- Invertebral disks
Hyaline Cartilage-smooth with large nuclei.
Bone Tissue
Bone tissue is the osseus tissue.
Rigid due to mineral salt
The layers in bone tissue are haversian canals, mellae, osteocytes.
Blood and Reticular
The Blood tissue circulates throughout the body
The Reticular tissue is scattered throughout the body
Blood- identify due to platelets.
