hollow organ 2 Flashcards
bagian penting pada diafragma
1.Crura: Right crus is larger and longer than the Left
crus. Right crus originate from vertebrae L1 to L3
(the left one originates from L1 to L2). Right crus
splits to enclose the esophagus
2.Medial Arcuate Ligament (Medial Lumbocostal
Arch): Extends from the body of L1 to the
transverse process of L1 and passes over the
psoas muscle and the sympathetic trunk
3.Lateral Arcuate Ligament (Lateral Lumbocostal
Arch): Extends from the transverse process of L1
to rib 12 and passes over the quadratus lumborum
letak diafragma
Arises from the xiphoid process (sternal part), lower six
costal cartilages (costal part), medial and lateral
lumbocostal arches (lumbar part), vertebrae L1 to L3 for
the right crus, and vertebrae L1 to L2 for the left crus

1.Vena Caval Hiatus (Vena Caval Foramen): Lies in
the central tendon of the diaphragm at the level of
T8 and transmits the IVC and occasionally the right
phrenic nerve
2.Esophageal Hiatus: Lies in the muscular part of the
diaphragm (right crus) at the level of T10 and
transmits the esophagus, anterior and posterior
vagal trunk, esophageal trunk of left gastric vessel
3.Aortic Hiatus: Lies behind or between two crura at
the level of T12 and transmits the aorta, thoracic
duct
jalannya vena azygos, hemiazygos dan vena sphlanica
Azygos vein and Right Greater Sphlancnic
nerve enter the abdomen through the split
between medial and intermediate part of the
right crus, while Hemiazygos vein and Left
Greater Sphlancnic nerve through the split
between medial and intermediate part of the
left crus.
Sympathetic trunk enter the abdomen through
the split between the intermediate and lateral
part of the left and right crus.
hollow organ terdiri dari
esofagus, gaster, intestinum crassum, intestinum tenue.
letak esofagus
• Lies to the left of the midline • Enters the abdomen through the esophageal aperture (T10) • Ends at the GASTROESOPHAGEAL JUNCTION/CARDIAC ORIFICE of the stomach (40 cm from the incisor teeth)
fungsi esofagus
• Conduct food from the
pharynx into the stomach
hubungan esofagus dengan organ lain
• Posterior to the left lobe of the liver • Anterior to: – The left crus – The left inferior phrenic artery – The left greater splanchnic nerve
arteri esofagus
• Arteries: – Left gastric artery (Esophageal branches) – Additional supply: *Left inferior phrenic artery *Upper short gastric arteries *Esophageal branches of the thoracic aorta
vena esofagus
– Drain via plexuses to:
- Left gastric vein
- Upper short gastric vein
nerve esofagus
• Nerve supply: – Parasympathetic fibers (n. X) – Sympathetic fibers (T5-T12)
lokasi gaster
• Between the esophagus and the duodenum • In the upper abdomen, lying in the left hypochondriac, epigastric, and umbilical region
fungsi gaster
- Storage of food
- Mixes the food with gastric secretion
chyme - Controls the rate of delivery of chyme
to the small intestine
bagian gaster
• Fundus: – upward and to the left of cardiac orifice (incisura cardiaca) • Body (Corpus): – From cardiac orifice incisura angularis • Pyloric antrum: • Pylorus: – Pyloric sphincter – Pyloric canal
