The main bulk of the tissue consists of intercellular.
The loose connective tissue contains cells, fibers, and ground substance in roughly equal parts.
(b) Tendon is a specialized connective tissue. Areolar tissue : The areolar tissue is also known as loose connective tissue. Connective tissue generally consists of a considerable amount of extracellular material called matrix. Dense regular - tendons 2. General connective tissue is either loose, or dense, depending on the arrangement of the fibres. Loose (areolar connective tissue) is the most abundant form of collagenous connective tissue. Download Full PDF Package. Bloomington, Male reproductive tract folder, epididymis #5 ‐Example of pseudostratifiedcolumnar epithelium with stereocilia. (a) Areolar tissue is a loose connective tissue. (Take a facial cotton pad and stretch it gently in random directions!) It is loose because we can see a lot of space between the fibers. Dense Connective Tissue: • contains more numerous and thicker fibers and far fewer cells than loose CT 1. dense regular Connective Tissue – consists of bundles of collagen fibers and fibroblasts – forms tendons, ligaments, and aponeuroses – Function = provide strong attachment between various structures 22. The large, pale nucleus is that of a fibroblast while the darker nuclei are those of fibrocytes. Found in most tissues of the body. It is sub divided in to: a) Loose connective tissue: Here the fibers are loosely woven. • Form supportive infrastructure in solid organs. -Small amounts of connective tissue are found intermingled with other tissues throughout all organs of the body.-Depending on the type (e.g. Loose connective tissue is the most common type of connective tissue in vertebrates. It holds organs in place and attaches epithelial tissue to other underlying tissues.
Collagen, elastic, and reticular fibers present. dense irregular is made up of elastic fibers and a protein fiber called collagen which provide protection to the tissue and/ or organ it surrounds supporting connective tissues fibrocartilage provides and gives support to attach surrounding … Tissues Group of cells similar in structure and function four types Perform many vital function epithelial muscular connective nervous Credits 2.

The four basic types of tissue are epithelial tissue, connective tissue, muscle tissue, and nervous tissue. This is areolar connective tissue. All fiber types form a loose network Fibroblasts make all fibres and ground substance. Connective tissue propper a. loose connective tissue b. dense connective tisssue - regular - irregular 2. Ex. Dense Connective Tissue. 3. Warm-Up What type of connective tissue is shown below? The connective tissue fibers form a network around the airways and airspaces which allows the lung to expand and prevents excess tissue recoil and so preventing their collapse. Download PDF. The word tissue derives from the Old French word meaning “to weave,” reflecting the fact that the different tissues are woven together to form the “fabric” of the human body. “‘Loose’ connective tissue forms a network extending throughout the body including subcutaneous and interstitial connective tissues. dissection, loose connective tissue looks like cotton wool. reticular Loose Connective Tissue. • Protein = collagen. 4-4: Circulating and loose connective tissue, p. 67, PPt 29.
Connective tissues include cartilage, bone, adipose, and blood. Download Free PPT. 2. 1. Dense connective tissue is enriched in collagen fibers with little ground substance. Compared to a herring bone pattern. 2) Mucous = transient tissue appearing in normal development of CT and as Wharton's Jelly of umbilical cord - contains large stellate fibroblasts; matrix contains delicate collagen fibers in mucoprotein gelatinous ground substance. ?? (d) Adipose tissue is a dense connective tissue. Connective tissue consists of scattered cells immersed in an intercellular material called the matrix. Loose connective tissue (LCT), also called areolar tissue, belongs to the category of connective tissue proper. Connective tissue, as the name implies, is a term given to several different tissues of the body that serve to connect, support and help bind other tissues in the body. Structure of vessels 4 - Capillaries.
Technology. MCQs on Connective Tissue : 1. For example, blood is classified as connective tissue because it consists of red blood cells (erythrocytes) suspended in a liquid matrix (plasma). The thick purple fibers are collagen, the thin purple ones are elastin, and the purple dots are the nuclei of the scattered cells. Open navigation menu. Tendon contains a high ratio of collagen to number of cells and the collagen fibers are arranged in parallel arrays along the lines of tension.
Usually there is more extracellular matrix than cellular material.
In vertebrates, it is composed of blood cells suspended in a liquid called blood plasma. Tissue_Types_ppt (1) - View presentation slides online. Cells of bone are called osteocytes. I have supplemented these with images I found by Googling tissue types. Blood. 1. Collagen fibers predominate, but elastic and reticular fibers are also present. It consists: i) Areolar connective tissue: It is the most widely connective tissue. It contains all three types of fibers (collagen, elastic, and reticular), which are distributed randomly and crisscross in all directions, as shown in Figure 1.
dissection, loose connective tissue looks like cotton wool. 2. Blood vessels, muscles, and nerves all have a loose wrap of connective tissue. Loose connective tissue - delicate, flexible, not very resistant to stress, well vascularized. underlies all membranes. • Line body cavities that do not open to the outside. It, form from Mesenchyme and does not change after the birth. 1. Fig. Dense Connective Tissue: 2. It is most widely distributed connective tissue in the animal body. Loose Connective Tissue Predominant fiber type is. Also contains rete ovarii which is a solid cellular cords or networks of irregular channels lined by cuboidal epithelium. the three basic types of fibers that are found in connective tissue are collagen fibers, elastic fibers, and reticular fibers.What three basic types of fibers are found in connective tissuewww.answers.com/Q/What_three_basic_types_of_fibers_are_found_in_connective_tissue
It is found beneath the skin, around joints, padding the kidneys and other internal organs, and in certain abdominal membranes. Features. Dense Regular Dense Irregular Loose One way that connective tissue varies in mechanical strength is by the density and organization of its collagen fibers.
8 More connective tissue. Connective tissue. All connective tissues originate from embryonic mesenchyme, a tissue developing mainly from the middle layer of the embryo, the mesoderm.Mesenchyme consists largely of viscous ground substance with few collagen fibers (Figure 5–1).Mesenchymal cells are undifferentiated and have large nuclei, with prominent nucleoli and fine chromatin. Types of connective tissues: Loose, Dense & Specialised. 2.

Adipose - fat II. Connective tissue can further be broken down into three categories: loose connective tissue, dense connective tissue, and specialized connective tissue. 4-5: Dense connective tissue, cartilage, and bone, p. 69, PPt 33. Loose connective tissue is found between many organs where it acts both to absorb shock and bind tissues together. Bone, cartilage, ligaments, and adipose tissue (fat) are also considered connective tissue. The kinds and amounts of fiber and ground substance determine the character of the matrix, which in turn defines the kind of connective tissue. The ECM is composed of a moderate amount of ground substance and two main types of protein fibers: elastic and reticular fibers. Classification of Connective TissuesI. This type of connective tissue is characterized by a loose, irregular arrangement of connective tissue fibers within the abundant ground substances. Loose connective tissue. Areolar tissue is the most common type of connective tissue. The loose CT seen here is highly cellular and contains fine CT fibers giving it a pale pink appearance. Epithelial Tissue Cellular classified by shape and number of layers separates the body from open spaces Home Squamous cuboidal columnar Transitional 3. Most widely distributed connective tissue.
In submucosa of primary bronchi, you will find moderate dense fibro-elastic connective tissue.
These cells have round, eccentric nuclei with slightly basophilic cytoplasm (indicating the presence of RNP). Skeletal tissue.
