Pharynx is shared by 2 systems

Respiratory
Digestive

1

Pharynx as a respiratory organ is a muscular passage from the...

Nasal cavity to larynx

2

Other name of Pharynx

Throat

3

3 regions of the pharynx

Nasopharynx
Oropharynx
Laryngopharynx

4

Pharynx as a digestive organ is a muscular passage from....

Oral cavity to esophagus

5

Communication bet tympanic membrane and nasal cavity

Opening of eustachian tube

6

Region of pharynx where you can locate opening of Eustachian tube

Nasopharynx

7

Superior region behind nasal cavity

Nasopharynx

8

Middle region
Behind mouth

Oropharynx

9

Inferior region
Attached to larynx

Laryngopharynx

10

Regions of pharynx shared by Respi and Digestive systems.
Common passageway of food and air

Oropharynx
Laryngopharynx

11

Highly flexible
It closes the larynx so that food is only directed to esophagus

Epiglottis

12

Pharynx is suspended from

Base of skull to c6

13

Pharynx lies bet the bodies of the vertebrae and LARYNX between _

c4 to c6

14

Pharynx become continuous with the esophagus at

C6

15

3 types of muscular components of pharynx

Superior
Middle
Inferior constrictors

16

Point of attachment of the muscular components or constrictors of pharynx

Posterior midline raphe or PHARYNGEAL RAPHE

17

Structures assoc to the pharynx

Auditory tubes that enter the nasopharynx
Tonsils
pharyngeal or adenoids - nasopharynx
palatine-oropharynx
lingual-base of tongue

18

Not a constrictor because it remains open
Lies behind nasal and oral cavities

Superior constrictor muscle

19

Superior constrictor muscle is assoc to what muscle

Buccinator

20

Superior constrictor muscle:
Origin

Insertion:

O: pterygomandibular raphe
- mylohyoid line of the mandible
- medial pterygoid plate

Insertion:
apex of the petrous of temporal bone and pharyngeal tubercle of the occ bone (basilar part)

21

Constrictor that Lies behind the tongue and larynx

Middle constrictor muscle

22

Constrictor that plays a major role in swallowing

Middle constrictor muscle

23

Inferior constrictor muscle attaches anteriorly to 2 cartilages

Cricoid and thyroid cartilages

24

Constriction or sphincter, which is a boundary bet PHARYNX and ESOPHAGUS

Cricopharyngeus or Pharyngoesophageal constriction

25

Movt done by constrictors

Segmental or peristaltic movt

26

Sensory nerve supply of NASOPHARYNX

Max nerve

27

Sensory nerve supply of OROPHARYNX

Glossopharyngeal nerve

28

Sensory nerve supply of LARYNGOPHARYNX

Internal laryngeal branch of the vagus nerve

29

Will help stimulate pharynx to proceed to swallowing reflex. Recognize presence of food or air

Sensory innervation

30

Motor innervation of sup and middle constrictor muscles

Pharyngeal branches of the vagus nerve

31

Motor innervation of Inferior constrictor and cricopharyngeus

Recurrent branches of the vagus nerve

32

Swallowing reflex is performed by

Motor fibers and parasympathetic fibers of the vagus nerve

33

Lymph drainage of the pharynx: directly

Directly: Deep cervical lymph nodes
Indirectly: retropharyngeal or paratracheal nodes

34

2 masses of lymphoid tissue each Located in the depression on the lateral wall of the oral part of the pharynx between the palatoglossal and palatopharyngeal arches

Palatine tonsils

35

Blood supply of the pharynx

Ascending pharyngeal
tonsillar branches of the facial arteries
Branches of maxillary and lingual arteries

36

The surface of the palatine tonsil is pitted by numerous small openings that lead into the

Tonsillar crypts

37

Lymphoid tissue that surrounds the opening into the respiratory and digestive systems forms a ring

Waldeyers ring of lymphoid tissue

38

Covered by mucous membrane and its free medial surface projects into the pharynx

Palatine tonsils

39

Lateral part of the ring is formed by

Palatine and tubal tonsils

40

Lymphoid tissue around the opening of the auditory tube in the lateral wall of the nasopharynx

Tubal tonsils

41

Forms the upper part of the ring

Pharyngeal tonsil in the roof of the nasopharynx

42

Forms the lower part of the ring

Lingual tonsil - on the post 1/3 of tongue

43

Esophagus is how long

10in or 25cm long

44

Esophagus extends from the

Pharynx to the stomach

45

Esophagus begins at the level of the

Cricoid cartilage
Opp to the body of the c6

46

The esophagus commences in the midline but as it descends through the neck it inclines to what side

Left side

47

Anterior to esophagus

Trachea
Recurrent laryngeal nerves ascend one on each side, in the groove between the trachea and esophagus

48

Posterior to esophagus

Prevertebral layer of deep cervical fascia
Longus colli
Vertebral column

49

Lateral to esophagus

Lobe of thyroid gland
Carotid sheath

50

Arteries of the esophagus in the neck are derived from the

Inferior thyroid artery

51

Veins drain into the

Inf thyroid vein

52

Lymph drainage in the neck

Deep cervical lymph nodes

53

Nerve supply in the neck is derived from the

Recurrent laryngeal nerve
And sympathetic trunks

54

2 constrictions in the esophagus

Cricopharyngeus constriction
Cardiac constriction
