Answer
|
|
The maxillary sinus
communicates with the environment via the |
Middle nasal meatus
|
|
The initial event leading to
development of maxillary sinus is at when the embryo is |
32 millimeters
|
|
During embroyogenesis of maxillary
sinus, lateral nasal wall begins to fold to form |
Three nasal conchae ; three
nasal meatus |
|
The nasal meatus expands
immediately into nasal wall as it is formed |
Middle nasal meatus
|
|
During embroyogenesis of
maxillary sinus the middle nasal meatus expands in a |
Inferior direction
|
|
During embroyogenesis of
maxillary sinus the middle nasal meatus expands in an inferior direction due to the presence |
Lateral nasal capsule
|
|
The maxillary sinus is of 1
millimeter in diameter when the embryo is |
50 millimeters
|
|
The maxillary sinus has
developed its sinus epithelium when the embryo is |
50 millimeters
|
|
The anteroposterior diameter of
maxillary sinus perinatally is |
7 – 16 millimeters
|
|
The maxillary sinus expands and
modify itself till |
All permanent teeth erupt
|
|
The most common cause of
supernumerary maxillary sinus is |
Outpocketing of nasal mucosa at
two points |
|
Supernumerary maxillary sinus
have |
Two ostia
|
|
The best way to describe a
maxillary sinus is a |
4 sided pyramid
|
|
The inferior surface of the
maxillary sinus is formed by |
Alveolar and zygomatic process
|
|
The four sinus wall converge
laterally at an |
Obtuse angle
|
|
The perforation of the
maxillary sinus, ostium is seen at |
Base of sinus
|
|
The maxillary sinus ostium is
at the level of |
Middle nasal meatus
|
|
The expansion of pneumatic
spaces of maxillary sinus beyond the maxillary body is referred to as |
Recesses
|
|
The most common recesses of
maxillary sinus involves the |
Alveolar process
|
|
The occurrence of zygomatic
recesses brings the space of maxillary sinus in proximity with |
Superior alveolar nerve bundles
|
|
The presence of alveolopalatine
recesses indicate that the bone between tooth apex and sinus is |
Thinner
|
|
The most commonly involved
tooth with alveolopalatine recesses is the roots of |
Maxillary first molar
|
|
A fully well developed alveolar
recesses have |
Three depressions; 2 incomplete
bony septa |
|
The epithelial layer of
maxillary sinus can be best described as |
Pseudostratified, columnar and
ciliated |
|
The epithelial layer of
maxillary sinus is derived from |
Olfactory epithelium
|
|
The numerous cells in the
maxillary sinus epithelium is the |
Columnar ciliated cells
|
|
The attachment of ciliary
microtubules to the maxillary sinus epithelial cells is facilitated by |
Basal bodies
|
|
The basal bodies of the
maxillary sinus epithelial cells are found in the |
Apical segment
|
|
The typical cilia of the
maxillary sinus epithelial cells are made of |
9 + 1 pair of microtubules
|
|
The cilia facilitates the
movement of mucous lining the maxillary sinus epithelium generally from the |
Sinus interior toward nasal
cavity |
|
Congenital syphilis affect
maxillary sinus causing the sinus to be |
Smaller
|
|
The maxillary sinus is also
known as |
Antrum of Highmore
