Wang Peihua

Department of Otorhinolaryngology,

9th people’s hospital, School of medicine, Shanghai Jiaotong University


Circumscription of pharynx

Circumscription of pharynx

  • Pharynx is the junction between respiratory tract and alimentary tract.


Circumscription of pharynx1

Circumscription of pharynx

  • Superior: base of skull

  • Inferior: inferior border of C6

  • Anterior: Connect to nose, mouth and larynx

  • Posterior: Prevertebral fascia


Subsection of pharynx

Subsection of pharynx

  • (1) nasopharynx:

    skull base

    free edge of soft palate

  • (2) oropharynx:

    free edge of soft palate

    superior border of epiglottis

  • (3) laryngopharynx:

    superior border of epiglottis

    inferior border of cricoid cartilage


Nasopharynx epipharynx

Nasopharynx(Epipharynx)

  • a adenoid

  • b pharyngeal opening

    of auditory tube

  • c torus tubalis

  • d pharyngeal recess

  • e tubal tonsils


Oropharynx mesopharynx

Oropharynx(Mesopharynx)

  • a fauces

  • b glossopalatine arch

  • c pharyngopalatine arch

  • d tonsilla palatina

  • e lateral pharyngeal bands

  • f pharyngeal posterior wall


Laryngopharynx hypopharynx

Laryngopharynx(Hypopharynx)

  • a atrium of larynx

  • b vallecula epiglottica

  • c pyriform sinus

  • d postcricoid space


Structure of pharyngeal wall

Structure of pharyngeal wall

(一)layer of pharyngeal wall

1. mucous layer

2. fibrous layer

3. muscle layer:

①pharyngeal constrictor

②pharyngeal elevator

muscle group

③palatine velum muscle

group

4. Mantle layer


Applied anatomy of pharynx

(二)interfascial space

1. retropharyngeal space

2. parapharyngeal space


Pharyngeal lymph tissue

Pharyngeal lymph tissue

  • Pharyngeal lymphatic ring(waldeyer lymphatic ring)

    inner ring

    outer ring

Waldeyer

lymphatic ring


Structure of pharyngeal lymphatic ring

Structure of pharyngeal lymphatic ring

Pharyngeal submucous lymph tissue

(inner ring)

Lymph node of neck(outer ring)

  • adenoid tonsil

  • tubal tonsils

  • tonsilla palatina

  • lateral pharyngeal bands

  • folliculus lymphaticus of pharyngeal posterior wall

  • lingual tonsil

retropharyngeal lymph nodes

lymph nodes of

mandibular angle

submandibular lymph nodes

submental lymph nodes

drain to


Tonsilla palatina

Tonsilla palatina

(1) anatomy feature

a、location

b、appearance

c、construction features


Tonsilla palatina1

Tonsilla palatina

(2) blood vessel:①descending palatine artery

②ascending palatine artery

③tonsillar artery

④tonsillar branch of ascending

pharyngeal artery

⑤dorsal artery of tongue

(3) nerves: ① pharyngeal plexus

② superior maxillary nerve (Ⅴ2)

③ branches glossopharyngeal nerve.


Pharyngeal blood vessels and nerves

Pharyngeal blood vessels and nerves

  • arteries

  • veins

  • nerves


Applied anatomy of pharynx

  • 1、 how many sections has the pharynx been divided into? What are those anatomy defining points ?

  • 2、what is the composition of pharyngeal lymphatic ring (waldeyer lymphatic ring)?

  • 3、what is the blood apply of tonsilla palatina?
