Pharynx anatomy: a muscular tube in the neck connecting
the nasal and oral cavities with the larynx and esophagus,
enabling breathing, swallowing, and contributing to
phonation.
Pharynx and larynx anatomy: structures connecting the oral
and nasal cavities with the esophagus and larynx, enabling
breathing, swallowing, and voice production.
Salivary glands: parotid, submandibular, and sublingual
glands that produce saliva, initiating digestion, and lubricating
the mouth, and facilitating swallowing and oral protection.
Paranasal sinuses: air-filled cavities in the skull that reduce
its weight, enhances voice resonance and helps filter, humidify,
and protect the respiratory system through mucus production.
Vocal cords in whisper: the position where they approximate
without full vibration, allowing airflow and producing a soft,
low sound without the intensity of normal phonation.
