  2. Vocal resonation - Wikipedia

    en.wikipedia.org/wiki/Vocal_resonation

    The nasal cavity. The nasal cavity is the third most effective resonator. The sinuses. In spite of being traditionally referred to as resonators by many singers and teachers, the sinuses consist of small closed air pockets, not acoustically connected to the vocal tract, and with no proven role in voice resonance.

  3. Nasal administration - Wikipedia

    en.wikipedia.org/wiki/Nasal_administration

    The major part of the approximately 150 cm 2 surface in the human nasal cavity is covered by respiratory epithelium, across which systemic drug absorption can be achieved. The olfactory epithelium is situated in the upper posterior part and covers approximately 10 cm 2 of the human nasal cavity. The nerve cells of the olfactory epithelium ...

  4. Olfactory epithelium - Wikipedia

    en.wikipedia.org/wiki/Olfactory_epithelium

    The olfactory epithelium is a specialized epithelial tissue inside the nasal cavity that is involved in smell. In humans, it measures 5 cm 2 (0.78 sq in) [1] and lies on the roof of the nasal cavity about 7 cm (2.8 in) above and behind the nostrils. [2] The olfactory epithelium is the part of the olfactory system directly responsible for ...

  5. Cribriform plate - Wikipedia

    en.wikipedia.org/wiki/Cribriform_plate

    In mammalian anatomy, the cribriform plate ( Latin for lit. sieve -shaped ), horizontal lamina or lamina cribrosa is part of the ethmoid bone. It is received into the ethmoidal notch of the frontal bone and roofs in the nasal cavities. It supports the olfactory bulb, and is perforated by olfactory foramina for the passage of the olfactory ...

  6. Adenoid - Wikipedia

    en.wikipedia.org/wiki/Adenoid

    Adenoid. In anatomy, the pharyngeal tonsil, also known as the nasopharyngeal tonsil or adenoid, is the superior -most of the tonsils. It is a mass of lymphatic tissue located behind the nasal cavity, in the roof of the nasopharynx, where the nose blends into the throat. In children, it normally forms a soft mound in the roof and back wall of ...

  7. Inferior nasal concha - Wikipedia

    en.wikipedia.org/wiki/Inferior_nasal_concha

    The inferior nasal concha ( inferior turbinated bone or inferior turbinal/turbinate) is one of the three paired nasal conchae in the nose. It extends horizontally along the lateral wall of the nasal cavity and consists of a lamina of spongy bone, curled upon itself like a scroll, ( turbinate meaning inverted cone). [1]

  8. Ethmoid bone - Wikipedia

    en.wikipedia.org/wiki/Ethmoid_bone

    Ethmoid bone. The ethmoid bone ( / ˈɛθmɔɪd /; [1] [2] from Ancient Greek: ἡθμός, romanized : hēthmós, lit. 'sieve') is an unpaired bone in the skull that separates the nasal cavity from the brain. It is located at the roof of the nose, between the two orbits. The cubical bone is lightweight due to a spongy construction.

  9. Sphenoid sinus - Wikipedia

    en.wikipedia.org/wiki/Sphenoid_sinus

    The sphenoid sinus is a paired paranasal sinus occurring within the body of the sphenoid bone. It represents one pair of the four paired paranasal sinuses. [1] The pair of sphenoid sinuses are separated in the middle by a septum of sphenoid sinuses. Each sphenoid sinus communicates with the nasal cavity via the opening of sphenoidal sinus.
