Hair Tonic: What It Is And How To Use It. Hair tonic is an âold schoolâ hair styling product. It makes the hair look glossier (though some say greasier), something which many people viewed as a sign of healthy hair. The oils in the hair tonic also help hold the hair in place, making it easier to style, much like mousse or hair spray.
Larynx. the complex of cartilages, muscles, and ligaments that form the initial section of the trachea in terrestrial vertebrates and man, usually containing the vocal apparatus. The laryngeal cavity is divided into the anterior larynx, or vestibule, and the posterior larynx.
The LARYNX is an apparatus made up of cartilage, ligaments, muscles, and mucous membrane, which guards the entrance to the lower respiratory passages (trachea, bronchi, and lungs) and houses the vocal cords.Figure 4 shows the major cartilaginous and ligamentous structures which make up the larynx.he PHARYNX is a fibromuscular tube which extends from the base of the skull to the lower border of the cricoid cartilage (at which point it becomes the esophagus). Portions of the pharynx lie posterior to the nasal cavity (nasal pharynx), oral cavity (oral pharynx) and larynx (laryngeal pharynx).
