Function- Binding and support
Description- This tissue is composed of adipocytes (fat cells) specialized for fat storage. It can appear as empty bubbles with few cells scattered around.
Location- It is found everywhere areolar tissue is located. It is found in bone marrow and the bone surface. It is also found around the kidnet, heart, joints, eyeball, under the skin, in the abdomen, and breasts.
Function- This tissue provides protection and, since it is a poor conductor of heat, also insulation. It gives support and provides and energy reserve
Description- This is the most widely distributed connective tissue. It is made of many fibers and several types of cells in a gel-like matrix. It looks like reticular tissue, but contains much more fibers.
Location- It makes up collagen, can be found in the subcutaneous layer of skin, mucus membranes of blood vessels, around nerves, and around organs and capillaries.
Function- the fibers and matrix allow the tissue to provide strength, elasticity, and support. It also wraps and cushions organs and holds tissue fluid.
Description- This tissue is a combination of red blood cells (RBC), white blood cells (WBC) and platelets in a fluid matrix (plasma). The RBCs appear as round bubbles (usually pink) with spots of blue and white blobs (platelets and WBCs)
Location- This tissue is located within blood vessels.
Function- This tissue functions in the transport of gases, nutrients, wastes, and other substances around the body.
Description- This tissue is made of few cells with much extracellular calcium carbonate. It forms in round columns. It can appear as broken glass, or the rings of tree trunks with hollow middles.
Location- It is located everywhere in the skeleton is located in the body.
Function- It serves to provide support and protection in the body.
Dense regular/ dense white fiber (DWFCT)
Description- This tissue is mostly composed of collagen fibers in bundles. Fibroblasts (fiber building cells) are arranged in rows. It can appear as a solid section of material when the fibers are faint or translucent.
Location- This tissue is located in tendons, ligaments, aponeuroses ( the thin sheets of paper/ plastic feeling material holding muscle to the body), and deep fascia around muscles. It is also around the heart, kidney, testis, liver, and lymph nodes.
Function- It primarily serves as tough support and connections.
Description- This tissue is composed of threadlike fibers in a matrix. It has much more fibers with areas of matrix.
Location- It can be found in the Eustachinan tube, larynx, and the ear.
Function- It functions as support and flexibility.
Description- This tissue can appear like hyaline, but very fibrous with thick collagen and less chondrocytes. It is not as firm as hyaline.
Location- It can be found in the intervertebral discs, the pubic symphysis, and the discs of the knee joints.
Function- It provides support and strength.
Description- This tissue is seen as chondrocytes (cartilage forming cells) in firm matrix. The chondrocytes can look like shiny clear discs
Location- This tissue helps to form the embryo, costal cartilage, nose, and trachea.
Function- The purpose of this tissue is to provide support and pliability.
Description- This tissue is seen as interlacing reticular fibers within a loose substance. It forms the framework of organs.
Location- It can be found in lymph nodes, the spleen, and the liver. It is also found binding smooth muscles together.
Function- Is main role is binding.
Description- Close arrangement of cells; no intercellular material; no blood vessels fast rate of mitotic division;
Location- Covers body surfaces. Lines body cavities. Forms the body of glands.
Function- Absorption, filtration, secretion, protection, diffusion, and osmosis.
Description- This tissue type appears as stratified squamous, but the nuclei are found at varying depths. The cells are attached to the basal membrane on one cell layer only and can appear like more cells are present than actually are. The cells may be ciliated.
Location- This tissue type is most found in the male urethra, large excretory duct, and the upper respiratory tract.
Function- Its main purpose is secretion and movement of material
Description- Rectangular shaped cells in a single layer. The Nuclei are at the base of each cell. Can appear slightly different based on its location and function.
Location- This tissue lines the stomach, large intestine, glands of digestion, gall bladder, uterine tube, and small intestine as microvilli.
Function- The function depends on the location, but usually serves to allow movement of materials, absorption, and protection.
Description- When viewed from above, this tissue appears as tightly fitted polygons. When viewed through a cross section, it appears as a single layer of cubes.
Location- It covers the ovary surface, lines the inner cornea, kidney tubules, and small ducts of glands.
Function- This tissue functions as secretion, absorption, and protection.
Description- When viewed from the side, it can appear as one layer of flat cells with a central nucleus. From above, the cells appear as cooked eggs next to each other.
Location- It is found in areas where there is little wear and tear, such as the alveoli of the lungs, the lungs, the lining of blood vessels, the lining of the pleural and pericardial cavities, the lens of the eye, and the eardrum.
Function- This tissue type serves for absorption, diffusion, osmosis, filtration, and secretion of materials.
Description- This tissue is uncommon in the body. It appears as rectangular cells with two nuclei at each end, because of the multiple layers.
Location- It is located in a few structures such as the male urethra, lactiferous glands, large salivary glands, and the female uterus.
Function- The primary role of this tissue type is protection and secretion.
Description- This tissue appears as several layers of flattened cells that are durable. It can be categorized as keratinized or non-keratinized.
Location- Appear where there is great wear and tear. Non-keratinized are found on wet surfaces such as the lining of the mouth, vagina, and esophagus. Keratinized is found on the skin.
Function- Non-keratinized serves to protect areas of wear and tear. Keratinized serve as protection by acting as a waterproof tough layer.
Description- This tissue can appear like stratified squamous or stratified cuboidal. The nuclei are randomly distributed throughout and the outer edges appear to bulge or fan out.
Location- It can be found at the lining of hollow structures that distend such as the ureters, bladder, urethra.
Function- It serves as protection and for distension.
Description- Groups of muscle cells (fibers) and Fibrous coverings can shorten by 1/3.
Location- All over the body.
Function- Locomotion or Movement.
Description- This tissue appears similar to skeletal, but has notable differences. The thick bands form branches and the striations may not be as clear. There are also intercalated discs (darks lines perpendicular to the direction of the fibers that segment the fiber).
Location- It is found in the heart.
Function- Its actions are involuntary and it contracts spontaneously sue to electrical signals. It serves to pump blood and maintain blood pressure
Description- This tissue forms long cylindrical cells with many nuclei. They look like tubes or thick bands with striations (thin lines that can look like stripes).
Location- This tissue can be found attached to bones and to each other.
Function- It provides voluntary movement and locomotion.
Description- This tissue is long and spindle shaped with a central nucleus and no striations. It can form sheets, and can appear as one solid object with many nuclei.
Location- It can be found on the walls of hollow organs, along the epithelium of digestive organs, urinary organs, and blood vessels.
Function- Its actions are involuntary and consist of slow sustained contractions in rhythmic patterns. It allows for actions or processes such as menstrual cramps, peristalsis, sperm movement, blood vessel dilation, and labor contractions.
Description- Made of Nervous and Glial Cells
Location- Brain, Spinal cord, and Nerves
Function- Conduct nerve impulses to control activities in the body.
Description- This tissue can be seen as separate individual web- like cells. The cells within the tissue have dendrites (branches), an axon (long branch), and a cell body.
Location- This tissue type is found in the brain, spinal cord, and nerves.
Function- The purpose of this tissue is to transmit electrical signals throughout the body.
