Anterior,
posterior and superior are the peritoneal cavity and intestines
Lateral – sidewalls
of the pelvisd
Inferior – broad ligaments and ovaries lie
below thetubes
Medial – uterus
lies between fallopian tubes
Supports fallopian tubes are held in place

lumen 1mm wide
·
The Isthmus - narrow part 2,.5cm from cornua of the
uterus
·
The Ampulla – wider portion 5cm longit extends from
the isthmus to the infundibulum usually fertilization takes place here
·
The Infundibulum – funnel shaped finged and which
is attached to the ovary. It is about 2.5 cm long; one is known as the fimbrae.
One of it extends to the ovary and is known as the fimbria ovarica
Layers - Lining in mucus membrane -
