1. Connective Tissues

2. CONNECTIVE TISSUE All connective tissue contains relatively  few cells  with large space between them. All connective tissue contains a  large amount of extracellular matrix  (ground substances and protein fibers). ​

3. Types of Connective Tissues The 4 Types of Connective Tissues Include: ​ 1) Connective Tissue Proper 2) Cartilage 3) Bone 4) Blood The four broad categories of connective tissue are classified according to the characteristics of their ground substance and the types of fibers found within the matrix. Blood

4. What Tissue Types Are Considered "Connective Tissue Proper"?   Connective tissue proper contains tissues that fall into 2 different categories. 1) Loose Connective Tissues 2) Dense Connective Tissues     There are 3 types of Loose Connective Tissue. 1) Areolar Connective Tissue 2) Adipose (Fat) Tissue 3) Reticular Tissue   There are 3 types of Dense Connective Tissue. 1) Dense Regular Connective Tissue 2) Dense Irregular Connective Tissue 3) Elastic Connective Tissue

5. Areolar Connective Tissue    A Type of Loose Connective Tissue Areloar connective tissue is very ' loose’.  Areolar tissue is composed of a lot of matrix and relatively few cells. The primary cell of areolar connective tissue is the flibroblast . The fibroblast function in the areloar tissue to form the fibers of the matrix and the surrounding  ground substance.

21. Adipose Connective Tissue   A Type of Loose Connective Tissue  Adipose (fat) tissue function to store energy and produce heat.  ​ Adipose (fat) cells, is considered a loose connective tissue of the connective tissue proper. There are actually two different types of fat tissue; white fat and brown fat

36. ​ Reticular connective tissue    ​ Reticular connective tissue  is a type of loose connective tissue that contains a network of reticular fibers. The word "reticulum" means (net or network). Reticular fibers are very noticeable in these tissues. These reticular fibers are synthesized by fibroblasts (also called reticular cells).

47. ​ Reticular connective tissue      Reticular connective tissue is found in bone marrow and surrounding the kidneys, the spleen, and the lymph nodes. ​ Reticular connective tissue forms a flexible 'skeleton' or internal framework, that can support many free blood cells (largely lymphocytes) in lymph nodes, the spleen, and red bone marrow.

49. DENSE CONNECTIVE TISSUE Dense connective tissue contains more collagen fibers than does loose connective tissue. As a consequence, it displays greater resistance to stretching. There are two major categories of dense connective tissue: regular and irregular

56. Dense regular connective tissue Dense regular connective tissue fibers are parallel to each other, enhancing tensile strength and resistance to stretching in the direction of the fiber orientations. Ligaments and tendons are made of dense regular connective tissue, but in ligaments not all fibers are parallel.

57. Dense regular connective tissue Dense regular connective tissue contains elastin fibers in addition to collagen fibers, which allows the ligament to return to its original length after stretching.

59. dense irregular connective tissue In dense irregular connective tissue, the direction of fibers is random. This arrangement gives the tissue greater strength in all directions and less strength in one particular direction.

60. dense irregular connective tissue In some tissues, fibers crisscross and form a mesh. In other tissues, stretching in several directions is achieved by alternating layers where fibers run in the same orientation in each layer, and it is the layers themselves that are stacked at an angle.

66. Elastic Connective Tissue True elastic connective tissue is very rare, and we have no slide specimens that show it. But elastic fibers are present in relatively high concentration in several organs, including the largest arteries in the body.
