Connective tissue is present throughout the human body and serves a variety of crucial functions beyond connecting body parts. In the muscles, every muscle fiber bundle is wrapped in a membrane of dense irregular connective tissue called the epimysium; the perimysium is composed of the same tissue (see below). (B) Dense Irregular Connective Tissue: It has fibroblasts and many fibres (mostly collagen) that are oriented differently. Dense Irregular Connective Tissue Function: able to withstand tension exerted in many directions; provides structural strength Location: fibrous capsules of organs and joints; dermis of the skin; submucosa of digestive tract Connective Tissue Dense Connective Tissue, Cartilage, Bone, Joints. Terms in this set (14) areolar tissue F. ... dense irregular connective tissue L. fibrous capsals of organs and joints, dermis of skin. Tendons and ligaments attach to bones, and the role of dense regular connective tissue is to transfer forces to bones. There are a few elastin fibers to give the tissue some resiliency. They are responsible for the synthesis of collagen and extracellular matrix. Flashcards. PLAY. Aponeuroses are important in attaching bone to muscle. Cytoplasm of young and active cells show basophilia due to the presence of high concentration of rough endoplasmic reticulum, mitochondria and many sets of Golgi apparatus. Our engaging videos, interactive quizzes, in-depth articles and HD atlas are here to get you top results faster. Connective tissue function & location. Connective tissue disease, any of the diseases that affect human connective tissue. They are also called gristle. Learning anatomy is a massive undertaking, and we're here to help you pass with flying colours. • Among the collagen fibers there is a network of elastic fibers as well, to limit the distensibility of the tissue. This arrangement allows the fibers to have a good resistance to forces pulling along a single axis, but also gives some ability to stretch. Connective tissue, group of tissues that maintain the form of the body and its organs and provide cohesion and internal support. The cells sit in a matrix made up of glycoproteins, fibrous proteins and glycosoaminoglycans , which have been secreted by the fibroblasts, and the major component of the matrix, is in fact, water. They are responsible for the synthesis of collagen and extracellular matrix. Loose irregular connective tissue includes, but is not limited to, the superficial fascial sheath of the body directly under the skin, the muscle and nerve sheaths, and the bed and framework of the internal organs. Dense connective tissue is often further divided into two main categories; dense irregular connective tissue and dense regular connective tissue. Adipose connective tissues are large fat located underneath the skin. It also contains fewer cells and less ground substance in comparison with the other type, loose connective tissue. Dense Connective Tissue: The three types of dense connective tissue are dense regular, dense irregular, and elastic tissue. Free Online Resources for Undergraduate Anatomy & Physiology. The collagen fibers are densely packed together and arranged in parallel to each other. Read more. 0 0. Kim Bengochea, Regis University, Denver, Author: Dense connective tissue, is one of the types of connective tissue also referred to as dense fibrous tissue due to relative abundance of the collagen fibers. Despite their density, ligaments can still be fairly elastic. Reading time: 7 minutes. Connective tissue includes several types of fibrous tissue that vary only in their density and cellularity, as well as the more specialized and recognizable variants, such as bone. An example of a dense regular connective tissue is a tendon. Learn. “I would honestly say that Kenhub cut my study time in half.” Connective tissues are the major supporting tissue of the body. The myofibroblasts are characterized by the presence of actin filaments and dense bodies. Their main function is to support and transmit mechanical forces. Dense irregular connective tissue is found in high concentrations in body parts where support is needed to prevent the effects of forces that pull in multiple directions. In general, fibroblasts become very active during wound repair and healing process, when they proliferate and form fibrous matrix. Ligaments need to be strong as they connect bones together, and hold joints in place. Its 3-dimensional structure allows it to withstand force from different directions. Reticular Connective Tissue: It is made up of reticular fibres. Able to withstand tension applied from many different directions. From the functional viewpoint it must be understood that even in "irregular" dense connective tissue, the collagen bundles are arranged to resist stretching in specific directions, and though the fibre bundles appear to run haphazardly, there is "order in the madness". Due to high portions of collagenous fibers, dense irregular connective tissue provides strength, making the skin resistant to tearing by stretching forces from different directions.
