Functions to serve as the mechanical lever systems for movements of the body and rigid structures to provide stable morphology of the body. Lab 3 ORGANIZATION of the BODY CELLS and TISSUES. An adjustment to a change in the internal or external environment requires a change in the direction of the stimulus. Basement membrane (extracellular matrix). As the bladder fills, it expands and the lining becomes thinner. All drawings should include clear and proper labels (and be large enough to view details).
It is termed "pseudo" because, although single, it appears to have multiple layers. These can include receptors and channels for transportation of substances that the epithelial cell needs to internalize or expel, or membrane specializations. A plane that divides an animal into dorsal and ventral portions is ________. Irregularly arranged fibrous connective tissues are found in areas of the body where stress occurs from all directions, such as the dermis of the skin. It is found in the epidermis of the skin. Squamous epithelia can be either simple or stratified. Click to see the original works with their full license. Sharks have cartilaginous skeletons, as does nearly the entire human skeleton during a specific pre-birth developmental stage. Terms in this set (124). Pseudostratisfied columnar epithilia occur in a single layer, but the arrangement of nuclei makes it appear that more than one layer is present. Tissue worksheet answer key. The part of a neuron that contains the nucleus is the. Transmembrane Protein. Polarity (apical, lateral and basal cell surfaces). The tissue is also found around and between most body organs.
Constriction of smooth muscle occurs under involuntary, autonomic nervous control and in response to local conditions in the tissues. In which we discuss epithelial cells as: simple (only 1 cell layer of epithelium), stratified (more than 1 cell layer of epithelium), or pseudostratified (appears to have multiple layers of cells, but all cells make contact with the basal membrane). Intercellular junctions are protein complexes on the basolateral cell membranes of epithelial cells. Now switch to High Power. For example, skin tissues protect our bodies from dirt and germs getting inside our bodies. Plants, animals, human beings, and birds are examples of multicellular organisms. They are specialized to pick up substances from the blood and modify them into a product that's then released from the cell. The fluid portion of whole blood, its matrix, is commonly called plasma.

Connective tissue is comprised of cells that produce different types of protein fibers that are exuded from cells that develop a matrix of protein and fluids that connect different tissues of the body into a network of tissues that provides functional units of the organ systems of the body. Multicellular glands can also be classified by the mode of their secretion; merocrine (excretion via exocytosis), holocrine (excretion with cell apoptosis) and apocrine (excretion by detaching the apical membrane). Uterine contractions during labor. Incorporated in organs whose primary function is other than endocrine (e. juxtaglomerular cells of the kidney, Leydig cells of the testes).
Contiguous squamous epithelial cells also provide a smooth flat surface over which fluids and other tissues can move with low friction. Vasodilation center. Epithelial cells are the building blocks of epithelial tissue. This is called a platelet or thrombocyte. A person feels satiated after eating a large meal. Compact bone is found in the shaft (or diaphysis) of a long bone and the surface of the flat bones, while spongy bone is found in the end (or epiphysis) of a long bone. Diabetes is often associated with a lack in production of insulin. Both tissues participate in vertebrate skeletal development and formation.
Drawings should be labeled with the specimen name and magnification. Each cell itself is made of various components that perform functions that all for the cell to maintain its own homeostasis.

Use the Coarse Knob to focus, image may be small at this magnification, but you won't be able to find it on the higher powers without this first step. Some glial cells are also shown. Sets found in the same folder. Fibrous connective tissues contain large amounts of collagen fibers and few cells or matrix material. Tissues are conglomerations of cells that share a similar function for the body that will work and interact with each other. The space between the formed elements of the tissue is filled with the matrix. The work bundles chronologically follow the detailed and interactive set of slideshows.
The cells are wider than they are tall, with an oval shaped nucleus. Based on the number of comprising cells – into unicellular and multicellular glands. Before we start off with studying tissues and cells it is important to able to use the microscope correctly is having the knowledge of magnification of the tissue through the microscope and what to do if something goes wrong. Thus they are found in the retina of the eye (microvilli), taste buds on the tongue (microvilli), organ of Corti (stereocilia) and ampullae in the inner ear (microvilli, stereocilia and cilia). As the urinary bladder fills, the epithelial layer unfolds and expands to hold the volume of urine introduced into it.

An electron with a speed of. Compare your slides and diagrams within your group. Organization of the Body. The types of epithelia are classified by the shapes of cells present and the number of layers of cells. Large quantities of microvilli are said to form a 'brush border', due to their appearance in histological preparation. A remnant of this cartilage persists in the outer portion of the human nose. Subclassifications include pseudostratified, ciliated or transitional. Smooth muscle does not have striations in its cells. Vesicle responsible for sequestering digestive enzymes for use by the cell on materials following pino-, or phago-cytosis. Check that they have labeled the organelle correctly and if correct move the next member. The main cell of the nervous system is the neuron, illustrated in Figure 14.
Functions as an open tube through the body to ingest and digest materials necessary to tissue repair and energetic balance. Other glial cells that are not shown support the nutritional and waste requirements of the neuron. Simple Cuboid (Kidney Slide).
