Skeletal muscle is under voluntary, somatic nervous system control and is found in the muscles that move bones. This type does not offer great protection, in fact in some environments the cells can be shed (desquamate). In the plant kingdom, tissues are divided into two different types: Meristematic tissue and Permanent tissue. Osteoblasts are active in making bone for growth and remodeling. The cell found in bone that makes the bone is called an ________. Epithelia specialized for protection, such as the stratified squamous keratinized epithelium of the skin, are multilayered and have a high cell renewal rate. Chapter 3 cells and tissues answer key. Which type of connective tissue has a mineralized different matrix? Sharks have cartilaginous skeletons, as does nearly the entire human skeleton during a specific pre-birth developmental stage. Correctly troubleshoot issues with microscope. Histologically striated (skeletal) muscle is a poly-nucleated (having more than 1 nucleus) cell with elongated striated muscle that attach to the skeletal structures via tendons and with nervous system stimulation allow for movement to occur. The nucleus is large, round and centrally located, and the cytoplasm is rich with organelles.
Fibrous connective tissues contain large amounts of collagen fibers and few cells or matrix material. This begins with the atom and the subatomic components (electrons, neutrons, protons) followed by the interaction of atoms with other atoms forming molecules that will interact with other molecules forming the macromolecules.

When faced with a sudden drop in environmental temperature, an endothermic animal will: - experience a drop in its body temperature. In this way, all muscle tissue, regardless of the distinct type will exhibit the following qualities: irritability, extensibility, elasticity, and contractility.
Incorporated in organs whose primary function is other than endocrine (e. juxtaglomerular cells of the kidney, Leydig cells of the testes). Transmembrane Protein. Then there is the liquid: protein matrix is dissolved within an aqueous solution, used for transportation connection between tissues and includes tissues such as blood and lymph. When a connective tissue has a high concentration of cells or fibers, it has proportionally a less dense matrix. Glands are classified in two ways; - Based on where and how they release their product – into endocrine and exocrine glands. A pathologist is a medical doctor or veterinarian who has specialized in the laboratory detection of disease in animals, including humans. This cellular covering has cilia at the apical, or free, surface of the cells. Discuss the different types of connective tissues in animals.
Which of the following statements about types of epithelial cells is false? A cell is mainly found in every living organism.
