Dense connective tissue is divided into 1) dense regular, 2) dense irregular, 3) elastic.
What is the function of the dense connective tissue?
The main roles of dense CT are to transmit forces over a distance and to connect different organs/muscles. Collagen fibres are disposed along the direction of mechanical loads present in that specific tissue.
What are the two types of dense connective tissue?
Dense regular connective tissue (DRCT) is divided into white fibrous connective tissue and yellow fibrous connective tissue, both of which occur in two forms: cord arrangement and sheath arrangement. In cord arrangement bundles of collagen and matrix are distributed in regular alternate patterns.
What is dense connective?
Dense connective tissue, also called dense fibrous tissue, is a type of connective tissue with fibers as its main matrix element. The fibers are mainly composed of type I collagen. Crowded between the collagen fibers are rows of fibroblasts, fiber-forming cells, that generate the fibers.
What are examples of dense connective tissue?
In particular, tendons and ligaments are examples of dense regular connective tissue. Tendons connect muscles to bones whereas ligaments connect a bone to another bone. Other examples include the perichondrium around the tracheal cartilage and the tunica albuginea around the testis.
What is the function of bony processes?
5. A bone’s shape makes possible its function; bony processes or grooves indicate places of attachment for muscles. 6. Compact bone makes up the wall of the diaphysis; the epiphyses are filled with spongy bone to reduce the weight of the skeleton.
What are the characteristics of dense connective tissue?
In this type of tissue, the collagen fibres are densely packed, and arranged in parallel. This type of tissue is found in ligaments (which link bone to bone at joints) and tendons (connections between bones or cartilage and muscle).
Where is dense elastic tissue found?
This type of connective tissue is found mostly in the reticular layer (or deep layer) of the dermis. It is also in the sclera and in the deeper skin layers.
What is loose and dense connective tissue?
Loose connective tissue works to hold organs in place and is made up of extracellular matrix and collagenous, elastic and reticular fibers. Dense connective tissue is what makes up tendons and ligaments and consist of a higher density of collagen fibers.
What is the function of fibrocartilage?
Fibrocartilage provides the tough material of the intervertebral discs; the intraarticular cartilages of the knee, wrist and temporo-mandibular joints; the articular cartilage of the temporo-mandibular joint and of the joint between the clavicle and the sternum.
Is skin connective tissue?
Skin is made up of connective tissue that consists of cellular components and an extracellular matrix. The extracellular matrix contains two main types of macromolecules: polysaccharide glycosaminoglycans and collagens.
