Describe the epithelial tissue on the cellular level and differentiate between the various kinds. Blood is also an exception Histology is the the field of study that involves the microscopic examination of tissue appearance, organization, and function. Cartilage and Bone are specialised forms of connective tissue. Connective tissue and epithelial tissue are the most predominant forms of tissue, which are located across different organs in our body. Endocrine glands are the glands without ducts that secrete hormones. Both tissues play a role in maintaining homeostasis within the body. a) How is transitional epithelium unique compared with other epithelial types? Organic matrix is materially like connective tissue due to the collagen and elastic . It is the nature of the matrix that defines the properties of these connective tissues. Epithelial tissue also doesnt have nerve supplies. The matrix surrounds the cells in connective tissue and it is made up of ground substance and fibers. epethilial tissue- structure.

Difference Between Connective Tissue Proper And Specialized Connective Connective tissue binds the various parts of the body together, providing support and protection. The blood cells, also called the formed elements, carried by plasma are the erythrocytes (red blood cells), leukocytes (white blood cells) and thrombocytes (platelets). However connective tissue differs from other types in that its cells are loosely, rather than tightly, packed within the ECM. The fibers are collagenous, reticular and elactic. attaches muscel to bone and bone to bone; resists stress applied in one direction. 4.2B: Types of Epithelial Tissue - Medicine LibreTexts epithelial appearance varies, depending on whether the tissue is stretched or relaxed; shape of cells at apical surface changes; some cells may be binucleated. Dense irregular connective tissue has collagen fibers randomly interwoven, forming a three-dimensional network resistant to distension in all directions. It lines organs so the lumen of organs will be lined with epithelial tissue and it also lines the inside of cavities, inside of the cavities of the organism. It seems that most animal cells are associated with an extracellular matrix. It binds together What are some characteristics The cells in the connective tissue are scattered throughout the matrix in no particular arrangement. mineral or hydroxyapatite, which is basically collagen fibers with different minerals like phosphates, magnesium, calcium, et cetera. The four major classes of simple epithelium are: 1) simple squamous; 2) simple cuboidal; 3) simple columnar; and 4) pseudostratified.

Then interspersed in the The two important constituents of bone are collagen and calcium phosphate that distinguish it from other similar structures like the enamel and chitin. Where filtration occurs, there is simple squamous epithelium. Compare and contrast the functions of the thymus and spleen. Ground substance and fibers make up the extracellular matrix (ECM). It develops from the endoderm or mesoderm or ectoderm from the embryological germ layer. It is divided into mesenchyme (in embryos) and mucoid connective tissue (umbilical cord). 2. I. EPITHELIUM (EPITHELIAL TISSUE) Describe the tissue composition of the two regions of the dermis. Reticular meshes filter lymph and provide a microenvironment for the passage and attachment of white blood cells. As nouns the difference between tissue and muscle is that tissue is thin, woven, gauze-like fabric while muscle is (uncountable) a contractile form of tissue which animals use to effect movement. The cells in the epithelial tissue obtain their nutrition from the cells underneath via diffusion. - [Voiceover] There are Connective tissue usually is highly vascular and innervated; it has a rich blood and nerve supply, except for cartilage and tendons, which is avascular and doesnt have nerves.
