Histology 2 – Connective Tissue (https://image3.slideserve.com/60760 45/histology-2-connective-tissuen.jpg)

Connective Tissue Facts (https://image3.slideserve.com/6076045/connective-tissuefacts-n.jpg)

Connective tissues run the gamut for vascularity. Some tissues are avascular (Cartilage), some are poorly vascularized (dense connective tissue), and some have rich blood supplies (bone).

Chapter 4: Carbohydrates

Unlike the tightly packed Epithelial tissues, living cells in connective tissues are separated by a non-living extracellular matrix (Ground Substance and Fibers).

(/adamdaniel/fibrosis(/JasminFlorian/chapterin-the-liver4role-ofcarbohydrates) histology)

Due to the matrix, connective tissues are able to bear weight, withstand tension, and endure abuses that no other tissues could tolerate.

Joints

Connective Tissues have many specific functions. Its major functions include Binding and support

Insulation Transportation of substances

Connective Tissue Facts (https://image3.slideserve.com/6076045/connective-tissuefacts3-n.jpg) Connective Tissues are made of three main components: Ground Substance Fibers Cells

Connective Tissue Facts – Ground Substance (https://image3.slideserve.com/6076045/connective-tissuefacts-ground-substance-n.jpg) The ground substance is the unstructured material between cells that contains the fibers. The ground substance holds large amounts of fluid and serves as a medium through which nutrients and other substances can diffuse between blood vessels and the cells.

Ground Substance (https://image3.slideserve.com/6076045/ground-substancen.jpg)

Ground Substance Connective Tissue Facts - Fibers (https://image3.slideserve.com/6076045/connective-tissuefacts-fibers-n.jpg) There are three types of fibers prevalent in Connective tissues A.) collagen fibers – are wide and wavy in appearance and generally stain pink. 79% of the protein in the body is collagen. B.) elastic fibers – are thin flexible fibers made from the protein elastin, that generally stain black. C.) reticular fibers – are actually thin collagen fibers. They have a spider web appearance and appear black under stain.

Fiber Types (https://image3.slideserve.com/6076045/fibertypes-n.jpg)

Elastic Fiber Reticular Fibers Collagen Fiber Connective Tissue Facts – The Cells (https://image3.slideserve.com/6076045/connective-tissuefacts-the-cells-n.jpg) Each major type of connective tissue has its own fundamental cell type in both immature and mature forms

Cell Types (https://image3.slideserve.com/6076045/celltypes-n.jpg)

Type of Connective Tissue Immature Cell Mature Cell Connective Tissue Proper Fibroblast Fibrocyte Cartilage Chondroblast Chondrocyte Bone Osteoblast Osteocyte Blood Hematopoietic Stem Cell Blood cell (macrophages) Other Cells Present (https://image3.slideserve.com/6076045/other-cells-presentn.jpg) Connective tissue is also home to many other cell types including Fat Cells, and mobile cells that migrate into the connective tissue from the blood stream, ie. mast cells and macrophages.

Connective Tissue Proper (https://image3.slideserve.com/6076045/connective-tissueproper-areolar-connective-tissue-n.jpg)Areolar Connective Tissue

Connective Tissue Proper (https://image3.slideserve.com/6076045/connective-tissueproper-areolar-connective-tissue4-n.jpg)Areolar Connective Tissue Areolar Connective Tissue is the most widely distributed connective tissue in the body. It serves as a kind of packaging material between other tissues.
