Q

Nasenaufbau

A

Septum nasi,
Conchae nasales -> Meatus nasi,
Sinus paranasales,
Choanae (Tuba auditiva) -> Nasopharynx
- Hiatus seminlunaris (zw. Proc. Uncinatus und Bulla ethmoidalis)
-> Infundibulum ethmoidale eine Verbindung zu den Sinus frontalis und maxillaris.

Q

Nasenschleimhaut

A
  1. Regio respiratoria = Conchae nasales + Sinus
    - Tunica muscosa: Respiratorisches Flimmerepithel, Becherzellen
    - Lamina Propria: Glandulae nasales (Anastomosen)
  2. Regio olfactoria - Concha naslis superior -> primäre Sinneszellen, also Neurone
    - an Lamina cribrosa Fila olfactoria -> Bulbus olfactorius

Q

Arteriell

A
  • A. Maxillaris (pars pterigopalatina) A. Sphenopalatina = Rr. Septales inferior + Aa. Nasales posteriores + laterales
  • A. Ophtalmica = Rr. Septales superior, A. Ethmoidalis anterior + posterior (durch Foramina etmoidales in Orbita)

= Locus Kiesselbachi

Q

Sinus paranasales (1:1) Arterien

A

Sinus frontalis:
- N. Trigeminus -> N. Ophtalmicus -> N. Ethmoidalis anterior
= Meatus nasi medius

Sinus ethmoidalis (Cellulae ethmoidales)
- N. Trigeminus, N. Ophtalmicus -> N. Ethmoidalis anterior + posterior
= M. Nasi superior + medius

Sinus Shpenoidalis:
- N. Trigeminus -> N. Ophtalmicus -> N. Ethmoidalis posterior
= Meatus nasi superior

Sinus maxillaris:
- N. Trigeminus, N. Maxillaris -> N. Infraorbilatis + Alveolaris Superior
= Meatus nasi medius

Ductus nasolacrimalis = Meatus Nasi inferior

  • Schneidersche membran (Becherzellen & Flimmerepithel, muköser & seröser Schleim, der in den Hiatus mündet) A. Sphenopalatina
  • Infundibulum ethmoidale (= Hiatus semilunaris)

Q

Innervation Nase

A

Sensibel: N. Nasociliaris -> N. Ethmoidalis anterior (N. Ophtalmicus), N. Infraorbitalis, N. Nasopalatinus (Canalis Incisivus) (N. Maxillaris)

Parasympatisch: N. Petrosus major (Facialis) -> N. Nasales posteriores [Ganglion pterigopalatinum!]

Symptaisch: Ganglion Cerviale superius -> Plexus caroticus internus -> N. Nasales posteriores

Sensorisch: Fila olfactoria -> N. Olfactorius
