The vocal tract is the cavity in human bodies and in animals where the sound produced at the sound source (larynx in mammals; syrinx in birds) is filtered.. In birds, it consists of the trachea, the syrinx, the oral cavity, the upper part of the esophagus, and the beak.
Nonetheless, for simplicity's sake the place of articulation is assumed to be the point along the length of the tongue, and the consonant may in addition be said to be central or lateral. That is, a consonant may be lateral alveolar, like English /l/ (the tongue contacts the alveolar ridge, but allows air to flow off to the side), or lateral ...
The production of speech is a highly complex motor task that involves approximately 100 orofacial, laryngeal, pharyngeal, and respiratory muscles. [2] [3] Precise and expeditious timing of these muscles is essential for the production of temporally complex speech sounds, which are characterized by transitions as short as 10 ms between frequency bands [4] and an average speaking rate of ...
Surface anatomy, or superficial anatomy, is important in human anatomy being the study of anatomical landmarks that can be readily identified from the contours or other reference points on the surface of the body. [1] With knowledge of superficial anatomy, physicians gauge the position and anatomy of deeper structures.
Anatomy of the larynx, anterolateral view. The larynx or voice box is an organ in the neck housing the vocal folds, which are responsible for phonation. In humans, the larynx is descended, it is positioned lower than in other primates. This is because the evolution of humans to an upright position shifted the head directly above the spinal cord ...
The muscles of the larynx adjust the length and tension of the vocal folds to 'fine-tune' pitch and tone. The articulators (the parts of the vocal tract above the larynx consisting of tongue , palate , cheek , lips , etc.) articulate and filter the sound emanating from the larynx and to some degree can interact with the laryngeal airflow to ...

The series was re-released in 2003 on DVD as Acland's DVD Atlas of Human Anatomy. The series uses unembalmed human specimens to illustrate anatomical structures. [3] Intended for use by medical, dental and medical science students, the video teaching aid uses simple language and high quality images.
