Lab 3 Organization Of The Body Cells And Tissues

The enterocytes of the small intestine has such specializations to facilitate absorption of food in the gut. In this way, all muscle tissue, regardless of the distinct type will exhibit the following qualities: irritability, extensibility, elasticity, and contractility. Do not use stage clips, try moving the slide around until you find something. Functions as an open tube through the body to ingest and digest materials necessary to tissue repair and energetic balance. Cuboidal epithelial cells are square shaped cells, they have a similar width to height ratio. Stratified Squamous Epithelial (Keratinized) (Skin). Connective tissues are made up of a matrix consisting of living cells and a non-living substance, called the ground substance. Stereocilia - a type of microvilli, but these are immotile and longer than microvilli. Based on the number of comprising cells – into unicellular and multicellular glands. • Slides: Lung and Bronchiole, Kidney, Skin, Urinary Bladder, Ileum, Fibrocartilage, Elastic Cartilage, Bone, Ligament, Areolar Connective Tissue, Reticular Connective Tissue, Skeletal Muscle Cardiac Muscle, Nerve Smear. Difference Between Cell And Tissue - A Detailed Overview. Dispersed within other epithelial cells, being specifically connected to autonomic neurons (diffuse neuroendocrine system - DNES). There are three types of cells in bone: osteoblasts, osteocytes, and osteoclasts. Examples of where this epithelial type can be found includes; covering the conjunctiva of the eye and in the largest ducts of exocrine glands. Now switch to High Power.

Quiz On Cells And Tissues

Check out our quizzes and free worksheets for identifying epithelial tissue. The wavy lines seen between the lacunae are microchannels called canaliculi; they connect the lacunae to aid diffusion between the cells. Different types of lymphocytes make antibodies tailored to the foreign antigens and control the production of those antibodies.

Ch 3 Cells And Tissues Answer Key

Skeletal muscle has striations across its cells caused by the arrangement of the contractile proteins actin and myosin. Cell layers: simple (one layer), stratified (multiple layers). 5 million cells per microliter. While smooth muscle is amorphic (no regular shape) muscle tissue with no visible striations that form a ring of muscle tissue surrounding lumens and organs of the body. When a connective tissue has a high concentration of cells or fibers, it has proportionally a less dense matrix. An electron with a speed of. A pathologist may oversee clinical laboratories for the evaluation of body tissue and blood samples for the detection of disease or infection. The space between the formed elements of the tissue is filled with the matrix. Two additional leukocytes in the blood are eosinophils and basophils—both help to facilitate the inflammatory response. Quiz on cells and tissues. Organelle responsible for aerobic phosphorylation of ADPàATP. Both tissues participate in vertebrate skeletal development and formation. Membrane extensions comprised of cytoskeletal protein core and cell membrane "envelope" responsible for motility, and locomotion, of the cell (or in colony movement of materials). Cardiac muscle, shown in Figure 14.

Instead, they are classified by the nature of their secretion into cells that produce proteins and cells that produce lipids (steroids). Chapter 3- Cells and Tissues Flashcards. 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). In summary, areolar tissue is tough, yet flexible, and comprises membranes. How might pyrogens cause the body temperature to rise?

Functions to eliminate metabolic waste products and toxins from the body. Membrane extensions comprised of rigid cytoskeleton that increases the total surface of the cell membrane. Epithelial tissue is avascular but innervated. Cells and tissues answer key strokes. It has the secretion and protective functions of all columnar epithelia. Elastic fibers are made of the protein elastin; this fiber can stretch to one and one half of its length and return to its original size and shape. Based on the structure of their secretory units, they are further divided into tubular, acinar and tubuloacinar. Apical specializations are different types of fingerlike cytoplasmic extensions of the apical surface. There are also two types of specialized stratified epithelium: keratinized and transitional.

Instead, their product, called hormone, diffuses into capillaries and travels through the bloodstream to reach its target organ/s and modify their functions. Cells and tissues pdf. These cells may have apical projections, such as microvilli or cilia. Internal environment of cell comprised of electrolytes, proteins and non-organelle materials. If you see a line in your viewing field, try twisting the eyepiece, the line should move, that is the pointer, and is useful for pointing out things to your lab partner or teacher. Blood clotting after an injury.
