Question 2

Diaphragm

Answer 2

●5 layers:
• Plaura + Fascia endothoracica
• M.phrenicus
• Fascia transversa abdominis + Peritoneum

●M.phrenicus
O: Corona muscularis
- Pars Sternalis
- Pars Costalis
- Pars Lumbalis
Meets in: Centrum tendineum
with opening:
- Foramen venae cavae

Pars costalis and lumbalis is conected by an arch:
°Archus lumbocostalis, beside there is a triangular region where the phrenic muscle.is absent:
°Trigonum lumbocostale

●Crus sinister and Crus dexter
Arising from the 3-4th lumbar vertebrae and forms together
°Hiatus aorticus, Right crus is thicker and extends more, forms the
°Hiatus oesophaeus

●A: Inspiratory m. and helps with increasing abd.preassure.

●Ligaments:
Lig.coronaria w/ Trigonum sinistra et dextra
