The ciliated epithelium tissue is located in the trachea, the bronchi of the lungs, the uterus, the fallopian tubes, and the efferent ducts, as well as in parts of the nasal cavities and the ventricular system of the brain. It's made up of columnar or cuboidal cells; the cilia, which come from the surface of the cells, are hairlike structures that move back and forth in waves and help transport fluids and other particles to the trachea or the fallopian tubes and the other organs that the ciliated epithelium covers. For example, the cilia help the egg cell move from the ovary to the uterus, and they also clear harmful particles from the airways.
Skeletal muscles are the muscles that are attached to the bones and joints; they are striated in appearance and are also under the conscious control of the organism, which is why they're called voluntary, as opposed to cardiac muscle, which is involuntary. Skeletal muscles are composed of skeletal muscle fibers, which are essentially cylindrical, multinucleated muscle cells; these fibers are organized in fascicles and surrounded by connective tissue. The main function of skeletal muscles is to maintain the stability of the bones, maintain body temperature, and control the movement of the skeleton.
The two main types of bone tissue are compact and spongy bone tissue. Compact bone tissue is made up of haversian systems or osteons, which are cylindrical in appearance. The osteons consist of concentric layers known as lamellae, which surround the osteonic or haversian central canal, which carries blood vessels and nerves. Osteons also have a Volkmann's canal, which is a perforating canal that transports blood vessels from the periosteum to the bones and connects the haversian canals.
