Which type of tissue stores lipid molecules?
Adipose tissue consists mostly of fat storage cells called adipocytes that store lipids as droplets that fill most of the cytoplasm (figure 4.6). A large number of capillaries allow rapid storage and mobilization of lipid molecules.
What is reticular tissue?
Reticular connective tissue is named for the reticular fibers which are the main structural part of the tissue. The cells that make the reticular fibers are fibroblasts called reticular cells. Reticular connective tissue forms a scaffolding for other cells in several organs, such as lymph nodes and bone marrow.
What is the tissue type that forms hard mineral Trabeculae?
The two different types of osseous tissue are compact bone tissue (also called hard or cortical bone) tissue and spongy bone tissue (also called cancellous or trabecular bone).
What is modified Areolar tissue?
The adipose tissue is a modified areolar tissue. The dense connective tissue has cells and fibres which are compactly arranged in the matrix. These tissues are of 2 types – dense regular connective tissue and dense irregular connective tissue.
Is elastin a proteoglycan?
Elastin is the main functional component of elastic fibers. Elastin protein has little structure and individual proteins are crosslinked into a network. Proteoglycans are proteins with long sugar side chains. The sugars are repeated disaccharides called glycosaminoglycans.
Is fibrocartilage connective tissue?
Fibrocartilage is a specialized form of connective tissue in which the ground substance is cartilage. The fibrous and cartilaginous components render this tissue extremely tough and resilient. The cell types found in this connective tissue include both fibroblasts/cytes and chondroblasts/cytes.
What is elastic cartilage?
Elastic cartilage is a structural cartilaginous tissue for non-load-bearing body parts, such as ears, nose, and epiglottis (Hutmacher et al., 2003).
Which tissue forms ligaments and tendons?
Dense connective tissue
Dense connective tissue is what makes up tendons and ligaments and consist of a higher density of collagen fibers. Examples of specialized connective tissues are adipose tissue, cartilage, bone, blood, and lymph.
What tissue forms disks between vertebrae?
Intervertebral discs consist of an outer fibrous ring, the anulus fibrosus disci intervertebralis, which surrounds an inner gel-like center, the nucleus pulposus. The anulus fibrosus consists of several layers (laminae) of fibrocartilage made up of both type I and type II collagen.
What tissue forms discs between vertebrae?
Cartilage. This is a flexible connective tissue found in many areas in the bodies of humans and other animals, including the joints between bones, the rib cage, the ear, the nose, the elbow, the knee, the ankle, the bronchial tubes, and the intervertebral discs.
What are glycosaminoglycans and proteoglycans?
Proteoglycans and Glycosaminoglycans Are Components of Extracellular Matrices and Cell Surfaces. Some of these proteoglycans contain only one GAG chain (e.g., decorin), whereas others have more than 100 chains (e.g., aggrecan). The matrix proteoglycans typically contain the GAGs known as CS or DS.
