Ducts of rivinus
The portion of the pharynx that is superior to the soft palate, it is continuous with the nasal cavity/choanae; the adenoids/pharyngeal tonsils are found in the upper post wall of the nasopharyngeal (none are visible)
Nasopharynx
Portion of the pharynx that lies between the soft palate and the upper border of the epiglottis (opening of the larynx) continuos with the mouth through the propharyngeal orifice or fauces (this is visible)
Oropharynx
This portion of the pharynx is continuous with the portion of the oropharynx, extending from the epiglottis above to the esophagus below; the anterior portion of the laryngophranux is formed by the epiglottis, the posterior is primed by cricoid cartilage of the larynx
Laryngopharynx
The opening from the oral cavity proper into the oropharynx
Fauces/faucial
Open air way to the trachea and instrument in phonation by means of the vocal folds (cords) variation of tension and shape of the vocal folds determines pitch and other qualities of the voice, located between the pharynx and trachea
Larynx
Adam’s apple, at the midline, anterior to the larynx, forms the prominence of the larynx, vocal folds pass anteriorly here
Thyroid cartilage
At the midline, anterior and superior to the thorns cartilage, many muscle attach here, does not articulate with any other bones, controls the position of the base of the tongue
Hyoid bone
Attaches to four bones: sternum and clavicle ( below), mastoid and occipital (above), bisect the neck diagonally, divides the neck into the anterior and posterior triangles
Sternocleidomastoid muscle
Bilateral, anterior region of the neck, extends superiority and anteriorly from the SCM muscle to the midline of the neck
Anterior cervical triangle
At the midline, under the chin, bordered by the digastric muscle ( anterior and posterior)
Submandibular triangle
Bilateral, area superior to the omohyoid muscle, bordered by omohyoid, SCM, digastric (posterior belly)
Carotid triangle
Bilateral, area below the omohyoid muscle, bordered by the omohyoid muscle, hyoid bone and thyroid cartilage
Muscular triangle
Lateral region of the neck, posterior and inferior to the SCM muscle
Posterior cervical triangle
Above the omohyoid muscle, bordered by theology pod muscle, SCM, and trapezius muscle
Occipital triangle
Below the omohyoid muscle borders by the omohyoid and SCM muscle and the clavicle bone
Subclavian triangle
The depression formed above the clavicle when the shoulders are hunched and bright forward
