RLE: Nose & Sinuses, Mouth & Oropharynx Flashcards
(69 cards)
Nose is composed of ??? and ???, and is lined with ???
bone and cartilage;
mucous membrane
The external nose consists of a ???(upper portion), ???, and two oval openings called ???.
bridge;
tip;
nares
The nasal cavity is located between the ???
roof of the mouth and the cranium
nasal cavity extends from the anterior nares (nostrils) to the posterior nares, which open into the ???.
nasopharynx
separates the cavity into two halves.
nasal septum
The front of the nasal septum contains a rich supply of blood vessels and is known as
This is a common site for nasal bleeding
Kiesselbach’s area
Four pairs of paranasal sinuses (???) are located in the skull.
frontal,
maxillary,
ethmoidal,
sphenoidal
air-filled chambers during speech
paranasal sinuses
paranasal sinuses are also lined with ??? that traps debris and propels it toward the outside
ciliated mucous membrane
are often a primary site of infection because they can easily become blocked.
sinuses
sinuses that are accessible to examination by the nurse
frontal sinuses(above the eyes)
maxillary sinuses (in the upper jaw)
The ??? and ??? sinuses are smaller, located deeper in the skull, and are not accessible for examination.
ethmoidal and sphenoidal
Cavities decrease the weight of the skull and act as ???
resonance
Two chambers divided by the septum.
External nostrils
Made up mainly of cartilage and bone and covered by mucous membranes. The cartilage also gives shape and support to the outer part of the nose.
Septum
Passages that are lined with mucous membranes and tiny hairs (cilia) that help to filter the air.
Nasal passages
Four pairs of air-filled cavities, also lined with mucous membranes.
Sinuses
are cavities, or air-filled pockets, near the nasal passage. As in the nasal passage, these are lined with mucous membranes.
sinuses
This sinus is located inside the face, around the area of the bridge of the nose. It is present at birth, and continues to grow.
Ethmoid sinus
This sinus is located inside the face, around the area of the cheeks. It is also present at birth, and continues to grow.
Maxillary sinus
This sinus is located inside the face, in the area of the forehead. It does not develop until around 7 years of age.
Frontal sinus
This sinus is located deep in the face, behind the nose. It does not typically develop until the teen years.
Sphenoid sinus
located behind the mouth and nose, serves as a muscular passage for food and air.
throat (pharynx)
3 pharynx from uppermost
nasopharynx
oropharynx
laryngopharynx
