Where is dense fibrous connective tissue found

The attachment of the connective tissue to the implant seems to strengthen previous findings about the long-term success of implants and their relationship with the surrounding tissues.

Since one of the major roles of fibrous connective tissue is to provide support to surrounding bone, tissue, and organs, its re-growth at implant sites means the implant may have some of the same structural support as natural teeth.

Erythrocytes, red blood cells, transport oxygen and some carbon dioxide. Leukocytes, white blood cells, are responsible for defending against potentially harmful microorganisms or molecules. Platelets are cell fragments involved in blood clotting.

Some white blood cells have the ability to cross the endothelial layer that lines blood vessels and enter adjacent tissues. Nutrients, salts, and wastes are dissolved in the liquid matrix called plasma and transported through the body.

Lymph contains a liquid matrix and white blood cells. Lymphatic capillaries are extremely permeable, allowing larger molecules and excess fluid from interstitial spaces to enter the lymphatic vessels.

Lymph drains into blood vessels, delivering molecules to the blood that could not otherwise directly enter the bloodstream. In this way, specialized lymphatic capillaries transport absorbed fats away from the intestine and deliver these molecules to the blood.

Connective Tissue Learning Objectives Identify and distinguish between the types of connective tissue: loose, dense, cartilage, bone, and blood Explain the functions of connective tissues.

Functions of Connective Tissues. Classification of Connective Tissues. Loose Connective Tissue. Dense Connective Tissue. Elastic connective tissue is a modified dense connective tissue that contains numerous elastic fibers in addition to collagen fibers, which allows the tissue to return to its original length after stretching Figure 4.

The lungs and arteries have a layer of elastic connective tissue that allows the stretch and recoil of these organs. Elastic Connective Tissue Elastic connective tissue consists of collagenous fibers with interwoven elastic fibers.

Fibrocartilage contains a large amount of collagen fibers, giving the tissue tremendous strength. Fibrocartilage comprises the intervertebral discs in vertebrate animals. Hyaline cartilage found in movable joints such as the knee and shoulder becomes damaged as a result of age or trauma. Bone, or osseous tissue, is a connective tissue that has a large amount of two different types of matrix material.

The organic matrix is similar to the matrix material found in other connective tissues, including some amount of collagen and elastic fibers.

This gives strength and flexibility to the tissue. The inorganic matrix consists of mineral salts—mostly calcium salts—that give the tissue hardness. Without adequate organic material in the matrix, the tissue breaks; without adequate inorganic material in the matrix, the tissue bends. There are three types of cells in bone: osteoblasts, osteocytes, and osteoclasts.

Osteoblasts are active in making bone for growth and remodeling. Osteoblasts deposit bone material into the matrix and, after the matrix surrounds them, they continue to live, but in a reduced metabolic state as osteocytes. Osteocytes are found in lacunae of the bone. Osteoclasts are active in breaking down bone for bone remodeling, and they provide access to calcium stored in tissues. Osteoclasts are usually found on the surface of the tissue. Bone can be divided into two types: compact and spongy.

Compact bone is found in the shaft or diaphysis of a long bone and the surface of the flat bones, while spongy bone is found in the end or epiphysis of a long bone. Compact bone is organized into subunits called osteons , as illustrated in Figure 4. A blood vessel and a nerve are found in the center of the structure within the Haversian canal, with radiating circles of lacunae around it known as lamellae. The wavy lines seen between the lacunae are microchannels called canaliculi ; they connect the lacunae to aid diffusion between the cells.

Spongy bone is made of tiny plates called trabeculae these plates serve as struts to give the spongy bone strength. Over time, these plates can break causing the bone to become less resilient. Bone tissue forms the internal skeleton of vertebrate animals, providing structure to the animal and points of attachment for tendons.

Figure 4. Spongy bone, inside the compact bone, is porous with web-like trabeculae. Blood vessels, nerves, and lymphatic vessels are found in the central Haversian canal. Rings of lamellae surround the Haversian canal. Between the lamellae are cavities called lacunae. Canaliculi are microchannels connecting the lacunae together. Osteoclasts bore tunnels into the bone and osteocytes are found in the lacunae. See also:.
