The Vertebral Column Skin, Hair, Nails, Sweat Glands The Immune System Blood Flow of the Heart (Circulation Flow) The Immune System Ø  Stratified compound epithelium is thicker than simple epithelium. The Limbic System and the Reticular Formation Visceral Sensory Neurons and Referred Pain Chemical Sense: Smell (Olfaction) CNS: Intro to Brain and Ventricles, Medulla Oblongata, Pons, Mid-Brain and Cerebellum The Cerebral Hemispheres Geography of the Skull Ø  The thickness of this tissue prevents the escape of urine to the surrounding tissues. A stratified squamous epithelium is made of two or more layers of squamous epithelial cells. The Urinary System: Kidneys Myocardium The Peripheral Nervous System Epithelial Cells. Protection for the Brain: Meninges, CSF, Blood-Brain Barrier Epithelial cells are usually characterized by the presence of a large nucleus and a polar arrangement. Disorders of the Central Nervous System Ø  Based on the shape of the cells which constitute the stratified epithelium, it may be of different types: $   Stratified squames epithelium found in the esophagus, $   Stratified cuboidal epithelium found in the sweat gland ducts, $   Stratified columnar epithelium seen in the mammary gland ducts. What are the functions of squamous epithelial cells? Ø  They are usually not considered as a separate class of epithelial tissue. These cells are most often associated with producing secretions and are therefore found lining the cells of the gastrointestinal tract. The Immune System Retrieved from https://biologydictionary.net/epithelial-cells/. Stratified—more than one layer of cells; Last name of tissue describes shape of cells. Chemical Sense: Taste (Gustation) Ø Stratified compound epithelium is thicker than simple epithelium. The Cardiovascular System Function of the Atrioventricular and Semilunar Valves Ø  Over-stressed epithelium becomes thick and keratinized. Geography of the Skull A simple columnar epithelium consists of a single layer of non-ciliated columnar epithelial cells. Conducting System of the Heart (Nervous Impulse Flow) Epithelial tissue can be further divided into ‘simple,’ where there is only one layer of cells, or ‘stratified,’ where there is more than one layer of cells. The Autonomic Nervous System (Includes sympathetic and parasymphathetic systems) Blood Vessels Integumentary System Part 2 In the smallest blood vessels, capillaries and sinusoids, endothelium comprises the majority of the vessel. Ø  Mucus protects the stomach epithelium from the high acidic pH and also from the digestive enzymes. In terms of shape, epithelial cells can be categorized as squamous, columnar, or cuboidal. Endothelial cells are epithelial cells that form a thin layer of simple squamous epithelium known as the endothelium. $   Respiratory passages such trachea, bronchi and bronchioles possess ciliated epithelium. Ø  All glands are made of epithelial cells. Central Nervous System: Spinal Cord The Autonomic Nervous System For example, a stratified squamous epithelium could have columnar or cuboidal cells at the deeper layers of the tissue. Blood Flow of the Heart (Circulation Flow) For example, the cells of the gastrointestinal and respiratory tracts might release mucus, and the cells of glands will secrete specific hormones. Wang, C. C., Jamal, L., & Janes, K. A. Ø  They also occur in the buccal cavity and virginal wall. The Central Nervous System Ø  The cells of transitional compound epithelium can modify or change their size and shape when required. The common types are simple squamous cells, simple cuboidal cells, simple columnar, stratified squamous, stratified cuboidal, stratified columnar and pseudostratified columnar. The Four Corners of the Heart Disorders of the Central Nervous System Ø  The side of the epithelial cells facing to the organ cavity possesses brush borders of microvilli. The Urinary System: Ureter and Urinary Bladder, The Cardiovascular System Conducting System of the Heart (Nervous Impulse Flow) Innervation of the skin: Dermatomes The Urinary System: Kidneys Cartilage and Bones The Lymphatic System (Spleen, Thymus, Lymphatic vessels, nodes etc) Cuboidal epithelial cells are cuboid in shape, and typically have a central nucleus, distinct from columnar and squamous epithelial cells. The Urinary System: Ureter and Urinary Bladder, Specialized Systems Peripheral Nervous System: Cranial Nerves Ø  Here, some of the cells of the tissue will be glandular or secretory. Layers of the Pericardium, Heart Wall and Spiral Arrangement Cartilage and Bones Protection for the Brain: Meninges, CSF, Blood-Brain Barrier (2017). This program was developed … [Read More], I have three premium flexibility programs that I offer and many of you have been clamoring for a bundle-package, so here it is! The Respiratory System (Lungs, Alveoli, Bronchi, Trachea, Larynx, Nasal cavities, etc) Ø  This condition of cells is called squames. Ø  It is a compound epithelium formed of many types of cells. Epithelial cells are the first cells to detect and respond to stimulation from the environment. Muscles of the Head The Lymphatic System (Spleen, Thymus, Lymphatic vessels, nodes etc) Chemical Sense: Taste (Gustation) Myocardium Ø  Epithelium constitutes the outer layer of body surfaces, linings of the alimentary canal and the walls of hollow structures. Ø  They occur in both simple and compound epithelium. Innervation of the skin: Dermatomes Muscles of the thorax for breathing and the pelvic floor (The Diaphragm) The Four Corners of the Heart These cells are involved in secretion and absorption and can be ciliated or non-ciliated. Special Senses Ø  Five types of simple epithelial tissue occurs in animals: Ø  They are flattened one layer thick epithelium. Layers of the Pericardium, Heart Wall and Spiral Arrangement Layers of the Pericardium, Heart Wall and Spiral Arrangement Ø  This layer is eventually become keratinized and flakes away. The Cardiovascular System The Vertebral Column Ø  Many layers of cells in the compound epithelium are formed by the mitotic cell division of the germinal layer.
