The Difference Between the Epimysium, Perimysium and Endomysium
However, a small amount of fine connective tissue (endomysium), secreted by the smooth muscles themselves and containing blood vessels and nerves, is found between smooth muscle fibers. Most smooth muscle is organized into sheets of closely apposed fibers. These sheets occur in the walls of all but the smallest blood vessels and in the walls of hollow organs of the respiratory, digestive, urinary, and reproductive tracts. In most cases, there are two sheets of smooth muscle with their fibers oriented at right angles to each other, as in the intestine.
Quality is generally described by 4 terms: security (hygienic quality), healthiness (nutritional quality), satisfaction (organoleptic quality), and serviceability (ease of use, ability to be processed, and prices). Satisfaction is driven by the qualities perceived by consumers. They include color, texture, and juiciness as well as flavor, which is associated with the aromas released in the mouth when the product is consumed. Satisfaction is also driven by technological qualities that reflect the ability of the product to be processed. They are mostly associated with a decrease in technological yield because of a decrease in water-holding capacity during cold storage (exudations) and cooking or because of damage that occurs after slicing.
The fibrillar phase occurs when the supersaturation of calcium and phosphate ions inside the matrix vesicles leads to the rupture of these structures and the hydroxyapatite crystals spread to the surrounding matrix.
Voluntary contraction of muscle is made possible by the somatic nervous system which sends out an action potential activating the contraction process. The process is accomplished by the sliding of myosin and actin over each other. Many diseases and disorders affect muscles, prominent among them is muscular polymyosis which causes inflammation of the muscles mainly around the torso. It’s believed to be caused by the unwanted action of the white blood cells and the symptoms include muscle weakness.
