2. Ainât âYou ainât gonna believe that âainâtâ ainât at the top of the list, but it ainât.â. You would think ainât would be a the top of the list, but youse will see soon why not. Donât get me wrong, this is a hall of fame non-word. It gets a point for being a contraction.
Peripheral nerves have three layers of connective tissue: Epineurium â is the outermost layer of connective tissue that is continuous with the dura mater. It also includes the connective tissue in between any fascicles (bundles) within the nerve. Perineurium â is the connective tissue sheath that surrounds a fascicle of axons. Endoneurium â is the delicate connective tissue fibers that surround individual axons. Subspecialty
The connective tissue sheath surrounding each fasciculus is the perymysium. Finally, by cutting through the perimysium and using a microscope, one would see the muscle fibers, which are the individual muscle cells. A sheath of connective tissue, called the endomysium, also covers each muscle fiber. It is generally thought that muscle fibers extend from one end of the muscle to the other; but under the microscope, muscle bellies often divide into compartments or more transverse fibrous bands(inscriptions).
