Inferior meatus
27
Arterial Supply of the Nose
Branches of: 1. Sphenopalatine artery 2. Anterior and posterior ethmoidal a 3. Greater palatine a 4. Superior labial a 5. Lateral nasal branches of facial a
28
anterior, where all arteries anastomose, where nose bleeding occurs
Kiesselbach’s area
29
Venous drainage of nose
Sphenopalatine,facial and ophthalmic veins
30
Nerve supply of Nasal septum
Nasopalatine n Greater palatine n Anterior ethmoidal n Posterior ethmoidal n
31
Smell innervation
Olfactory n | Olfactory bulb -forebrain
32
Air-filled extensions of the respiratory part of the nasal cavity
PARANASAL SINUSES
33
the 4 paransal sinuses
FRONTAL ETHMOID SPHENOID MAXILLARY
34
Sinus Between outer and inner tables of frontal bone | Detectable by 7 yo
Frontal sinus
35
Drains thru frontonasal duct into infundibulum w/c opens into semilunar hiatus of middlemeatus
Frontal sinus
36
NS of frontal sinus
br of supraorbital nerve
37
Comprise several cavities-ethmoidal cells | At ethmoid bone
Ethmoid sinus
38
Parts of EThmoid sinus
Anterior–drain into middle meatus Middle–form ethmoidal bulla,drain into middle meatus Posterior-drain into superior meatus
39
NS of ethmoid sinus
Nasociliary n[CN V1
40
Unevenly divided | Body of sphenoid
Sphenoid sinus
41
What separates the sphenoid sinus
thin plates of bone from optic nerve and chiasma ICA pit’y gl
42
Where does sphenoid sinus open
sphenoethmoidal recess
43
NS of sphenoid sinus
posterior ethmoidal nerve
44
Largest | Pyramidal shaped sinus
Maxillary Sinus
45
Parts of Maxillary sinus
``` Parts: Apex-into zygomatic bone Base-part of nasal cavity Roof-formed by floor of orbit Floor-formed by alveolar part of maxilla ```
46
Where does maxillary sinus drain?
Drains via maxillary ostium into middlemeatus
47
NS of maxillary sinus
Superior alveolar nerves
48
Fibromuscular tube that extends from the base of the skull to the lower border of the cricoid cartilage
Pharynx
49
point pharynx becomes the esophagus
Cricoid cartilage
50
Portions of the pharynx lie posterior to:
``` nasal cavity (nasopharynx) oral cavity (oropharynx) larynx (laryngopharynx) ```
51
Behind nasal cavities, mouth, larynx •Funnel-shaped •Musculo membranous wall
Pharynx
52
Parts continuous with Mucous Membrane
nasal cavity, mouth, larynx and tympanic cavity
53
Lining epithelium of upper Pharynx
ciliated columnar epithelium
54
Lining epithelium of Lowerr Pharynx
stratified squamous epithelium
55
Fibrous layer of Pharynx that is thicker, stronger, connected to base of skull
ABove
56
Fribrous layer of Pharynx continuous with submucous coat of esophagus
Below
57
The muscular walls of the pharynx are comprised of an outer layer made up of 3 circularly disposed muscles called
CONSTRICTORS
58
WHat are the constrictors?
SUPERIOR, MIDDLE INFERIOR PHARYNGEAL CONSTRICTORS
59
Composition of the Muscular Layer of Pharynx
superior constrictors middle constrictors inferior constrictors
60
How are the fibers oriented in the muscular layer of pharynx
circular fashion composed of: 1. stylopharyngeus ms. 2. salpingopharyngeus ms.
61
Origin of Superior Constrictor Muscle
1. medial pterygoid plate 2. pterygoid hamulus 3. pterygomandibular ligament 4. mylohyoid line
62
Insertion of upper superior constrictor
pharygeal tubercle
63
Insertion of middle superior constrictor
median fibrous raphe
64
WHat muscle of pharynx contracts and pulls post pharyngeal wall forward during swallowing aid soft plate in closing off nasopharynx
Superior Constrictor Muscle
65
NS of superio constrictor
pharyngeal plexus
66
Originates from stylohyoid ligament and lesser and greater cornua of hyoid
Middle constrictor
67
WHere middle constrictor muscle inserts
median fibrous raphe
68
NS of middle constrictor mus
pharyngeal plexus
69
Action of middle constrictor
contracts and propels food bolus down into esophagus
70
Origin of Inferior constrictor
thyroid cartilage | cricoid cartilage
71
Insertion of Inferioir constrictor
superior fibers –MCM lower fibers –esophagus median fibrous raphe
72
propel bolus of food into esophagus cricopharyngeus muscle –sphincteric effect
Inferior constrictor
