This lab will focus on the so-called connective tissue proper and cartilage; the next lab will focus on bone. It provides strong support while providing pads for shock absorption. Under the microscope, the cartilage fibers appear as whispy lines arranged in an orderly fashion with chondrocytes spaced throughout. Cartilage is a blended group of supportive tissue that provides … Although the myofibrils are transversely striated, each cell has only one centrally located nucleus. The tissue consists of an extensive network of fibers secreted by cells called fibroblasts. In this photo of areolar connective tissue, nuclei of cells are stained but the cytoplasm is pale and not distinguishable. It often fills in the spaces between epithelial, muscle and nervous tissue, forming what is known as the stroma of an organ, while the term parenchyma refers to the functional components of an organ. David Shier, Jackie Butler, Ricki Lewis. The chondrocytes (cartilage cells) that secrete this supporting matrix are located in spaces called lacunae. Note the dark blue transverse bands on the model called intercalated disks that mark the boundaries between the ends of the muscle cells. Observation . Blood and lymph are the two types of connective tissue in this sub-category. Projecting into the intestinal lumen (space) are numerous finger-like projections called villi, which function to slow the passage of food and increase the surface area for the absorption of nutrients. These specialized junctional zones are unique to cardiac muscle. Histology of human tissue, show connective tissue, hyaline degeneration of spleen as seen under the microscope Example of a typical loose connective tissue belonging to the submucosa of the stomach.

Connective tissue is a term used to describe the tissue of mesodermal origin that that forms a matrix beneath the epithelial layer and is a connecting or supporting framework for most of the organs of the body. A common way of classifying the many different types of connective tissue is to subdivide it into three main sub-categories, and further divide those subcategories into specific types of connective tissue. Most abundant are the fibres composed of the protein collagen. Connective tissue preparations are often messy with a number of blotches and shapes irrelevant to the main components of the tissue, which are the cells and the extracellular protein fibers. Pseudostratified ciliated columnar epithelium lines the trachea (windpipe) and larger respiratory passage ways. Simple columnar epithelium is composed of tall (columnar) cells that are closely packed together. Columnar epithelial cells line a large part of the digestive tract, oviducts and many glands. Epimysium, the connective tissue wrapping around skeletal muscles, and periosteum, the connective tissue wrapping around bones, are both connective tissues. Some fibroblasts have a contractile function; these are called myofibroblasts. Microscope--Connective Tissue study guide by Fancy_Li includes 38 questions covering vocabulary, terms and more.

Example: Tendons are composed of dense regular connective tissue. The fibroblast nuclei (stained purple) are quite flat. Simple columnar epithelium (cross section of the small intestine), 7. This tissue has a very even, smooth texture punctuated by lacunae and chondrocytes when seen under the microscope.The lacunae appear to be randomly scattered around the matrix. Bone and cartilage are connective tissues, as are blood and lymph, fat, ligaments, and tendons. Their spherical nuclei stain darkly and often give the layer an appearance of a string of beads. Four basic types of tissues are found in animals. Muscle tissue is specialized for contraction. Dense regular connective tissue contains densely packed collagen fibers that run in the same direction. Connective tissue - blood (Note: Erythrocytes - red blood cells; have hemoglobin; don't have nuclei because they lose it when made from bone marrow. Epithelial tissues are classified according to the number of cell layers that make up the tissue and the shape of the cells. There are three kinds of muscle tissue: Nervous tissue  is specialized for the reception of stimuli and conduction of nerve impulses. Fibroblasts are large flat spindle-shaped cells with processes that extend out from the ends of the cell body. This is probably _____.

The outermost portion of this skin is composed of a single layer of irregularly-shaped, flat (squamous) cells, which gives the tissue its name. Osteocytes or bone cells, (6) are located in spaces called lacunae (7) that are connected by slender branching tubules called canaliculi (8). The three main sub-categories of connective tissue are: These are the types of connective tissue that typically have all three of the defining characteristics listed above. The matrix is the extracellular material surrounding the cells. The contractile behavior of the heart is imparted by cardiac myocytes; its extracellular matrix and myocytes impart cardiac tissue with recoil 12, and viscoelastic behavior. white blood cells are the cells of the immune system under the microscope in laboratories. Image of micro, human, collagen - 130916818 Smooth muscle is often arranged in two layers that run perpendicular to one another, a circular layer whose fibers appear in cross section as shown on the model above and a longitudinal layer whose fibers appear like the ends of a cut cable when viewed on-end. The osteocytes (bone cells) are located in spaces called lacunae, which are connected by slender branching tubules called canaliculi. This slide shows a cross section of the esophagus, the first portion of the digestive tract that leads to the stomach. Interspersed among these columnar cells are goblet cells that secrete mucus into the lumen of the intestine. Are you good at identifying the different tissues? This slide is a cross section from the small intestine. The tissue sections after fixation and wax embedding are typically cut into two to five micron thin slices with a microtome before staining and transfer to a glass slide for examination with a light microscope. We’ll show you the way. Both tissues have a variety of cell types and protein fibers suspended in a viscous ground substance. Photo about Areolar connective tissue under the microscope view. The fibrous components of loose areolar connective tissue, when viewed with the light microscope, appear as colourless strands of varying diameter running in all directions, and, if not under tension, these have a slightly undulant course. This slide contains a section of cardiac muscle, which is striated like skeletal muscle but adapted for involuntary, rhythmic contractions like smooth muscle. Figure 8: Elastic cartilage Bone. that function as an integrated unit called an organism. The key difference between connective tissue and muscle tissue is that the main function of connective tissue is to provide a connection between tissues, organs and other body parts while the main function of the muscle tissue is to carry out movements of the body.. A tissue is a group of cells which have a common structure and function in our body. Start studying Lab 4: Connective Tissue Microscope Slides. connective tissue: A type of tissue found in animals whose main function is to bind, support, ... Its matrix appears transparent or glassy when viewed under a microscope.

Histology is the microscopic counterpart to gross anatomy, which looks at larger structures visible without a microscope. Stay connected with our beautiful campus and the faculty and friends who made your "La Crosse Experience" so special. Areolar connective tissue under the microscope view. As fibroblasts are the most common cells in areolar tissue, the majority of the nuclei seen here are probably fibroblast nuclei. Epithelial sells can be flat (squamous = "scale-like"), cube-shaped (cuboidal) or tall (columnar). s is a slide of a thin section taken from the mammalian kidney showing the many tubular ducts that make up much of this organ. Histological for human physiology. Supporting the trachea is a ring of connective tissue called hyaline cartilage. When the bone section is viewed under transmission electron microscope, it is possible to see collagen that makes up most of the organic matrix. Muscle Tissue Connective Tissue Epithelial Tissue Nervous Tissue Description: Muscle tissue consists of fibers Connective tissue performs such diverse functions as binding, support, protection, insulation and transport. The basic unit of structure in this type of bone is the Haversian system, or osteon. The walls of these ducts (pointed to by the red arrows) are comprised of simple cuboidal epithelial cells, which are usually six-sided in shape but may appear square from a side view. Image of blue, connective, loose - 130916821 In addition, students can see the osteoid tissue, which is uncalcified matrix.
