In birds, it consists of the trachea, the syrinx, the oral cavity, the upper part of the esophagus, and the beak. In mammals, it consists of the laryngeal cavity, the pharynx, the oral cavity, and the nasal cavity. [1] The estimated average length of the vocal tract in men is 16.9 cm and 14.1 cm in women. [2]

The score is assessed by asking the patient, in a sitting posture, to open their mouth and to protrude the tongue as much as possible. [1] The anatomy of the oral cavity is visualized; specifically, the assessor notes whether the base of the uvula, faucial pillars (the arches in front of and behind the tonsils) and soft palate are visible.
The mouth consists of two regions: the vestibule and the oral cavity proper. The vestibule is the area between the teeth, lips and cheeks. [3] The oral cavity is bounded at the sides and in front by the alveolar process (containing the teeth) and at the back by the isthmus of the fauces. Its roof is formed by the hard palate.
The body cavity immediately behind the mouth opening, known as the oral cavity (or cavum oris in Latin), [2] is also the first part of the alimentary canal, which leads to the pharynx and the gullet. In tetrapod vertebrates , the mouth is bounded on the outside by the lips and cheeks — thus the oral cavity is also known as the buccal cavity ...
The pharynx (pl.: pharynges) is the part of the throat behind the mouth and nasal cavity, and above the esophagus and trachea (the tubes going down to the stomach and the lungs respectively). It is found in vertebrates and invertebrates, though its structure varies across species. The pharynx carries food to the esophagus and air to the larynx.
The F2 frequency is higher for [i] because the oral cavity is short and the tongue is at the front of the mouth. The F2 frequency is low in the production of [u] because the mouth is elongated and the lips are rounded while the pharynx is lowered. [5] The IPA vowel chart has the cardinal vowels and is displayed in the form of a trapezium.
Fibronectin is a glycoprotein that is believed to act as a template for the oriented deposition of the collagen fibers, stabilizing the collagen fibrils. Fibronectin also acts as a skeleton for the elastic tissue formation. [4] Reticular and collagenous fibers were seen to run along the edges of the vocal cords throughout the entire lamina ...
