microvascular and neural components to support the epidermis. The dermal papillae increase the surface area that the epidermis and dermal papillae interact for a greater exchange between soluble molecules. The papillary region consists of loose connective tissue which is characterized by a thin, poorly organized bundles of collagen fiber, which consist primarily of type I and type III collagen.12 Collagen fibers that are located in the papillary dermis contain a greater amount of collagen type…
epithelium consisting of 4 distinct cell types (keratinocytes, melanocytes, Merkel cells, and Langerhans’ cells) and 4-5 distinct layers. The underlying dermis makes up a bulk of the skin. It is a tough, leathery layer composed of fibrous connective tissue. The dermis is the only vascularized region of the skin because of the nerves and blood vessels in the region. Thick skin covers the palms, soles of feet, and the fingertips.…
Tissues are a group of cells with a common structure and function. There are four main tissues in the body. Epithelial, connective, muscular, and nervous tissue are the four main types that make up the human body. Epithelial tissue lines body cavities, hollow organs, and ducts. It covers the body surfaces and forms glands. Connective tissue binds organs together, stores energy reserves as fat, and provides immunity. It protects and supports the body and its organs. Muscular tissue generates the…
What are the nonpolar parts of a phospholipid? c. Tail group 4. This is the only polar portion of a cholesterol molecule and it forms hydrogen bonds with the polar heads of phospholipids. d. –OH group 5. This type of membrane protein will extend throughout the entire membrane touching both the Intracellular fluid and the Extracellular fluid. e. Integral proteins f. Transmembrane proteins g. Integral proteins and Transmembrane proteins Ans: D…
mitosis and create the cells of the more superficial layers. Its function is to protect underlying tissues in areas that may be harmed. A non-keratinized form can be located in moist linings of the esophagus, mouth, vagina, urethra, and anus. However, a keratinized form can be located in the epidermis of the skin a dry membrane (Antranik,…
In a human body, there are four core classifications of tissues, which are epithelial tissue (plural form epithelium), connective tissue, nervous tissue, and muscle tissue. And each of these tissues has its own unique function in our body that makes us a perfect complement function organism. In the beginning, the simplest structural elements or atoms such as calcium (Ca +2) or sodium (Na +1) involve in the basic unit of living matter. These matters combine to form other matters like the fusion…
Task 1 Unit 11 Diagram Task 2 Unit 11 Four main tissue types Epithelial tissues One of the main tissue type are the one that characterize the epithelium .The epithelial tissues are used as cover for the all of our body surface both internal and external .Our epithelium it is formed by cells tissues that are one cell thick which make up the simple epithelium and from cells which are two or more cell thick which make up the stratified epithelium. The Simple Epithelium is made of…
ATryn is used in patients who have congenital antithrombin deficiency (inherited low levels of the protein antithrombin). Antithrombin is a glycoprotein produced by the liver and consists of 432 amino acids that inactivates several enzymes of the coagulation system. It is used when the patients are having surgery, to prevent problems due to the formation of blood clots in the vessels. In the body, antithrombin blocks thrombin, a substance that plays a central role in the process of blood…
specific types of tissues and organs. Without cell differentiation, no organism would be able to survive as cell differentiation is very vital for any living creature as it’s needed to make unique cells…
your systems, your body’s other systems could not help because their cells do not have the ability to do what the other systems cells did (Kinworthy, 5). An example of three systems that are needed for your body to be at optimal health would be the tissues, cardiovascular, and Integumentary systems (Kinworthy, 5). All of the systems work together to keep your body working the most efficient way (Kinworthy, 1).…
