Fallopian Tubes
nerve supply to fallopian tubes
sympathetic and parasympathetic fibers running from thoracic segment T11-T12 and lumbar segment L1
infundibulum
the funnel shaped, distal open end of each tube with frindged finger-like projections
isthmus
the narrow segment that extends fro the uterus
serosa
the outermost layer of the fallopian tube that is primarily longitudinal muscle produces peristaltic contractions to move the ovum toward the uterine cavity.
ampulla
the widest segment of the tube where fertilization of the ovum normally takes place
fimbriae
finger-like projections that gather around the ovary and, during ovulation, sweep the ovum into the ampulla
lymphatic drainage of the fallopian tubes
iliac and lateral aortic nodes
fallopian tube
(oviducts/salpinges) narrow muscular tubes that provide transport for the ovum from the ovaries to the uterus and is the place where fertilization normally occurs when the sperm meet the ovum in the tube.
3 layers of the fallopian tubes
1. mucosa 2. muscularis 3. serosa
muscularis
layer of smooth muscle that surrounds the mucosa and lies beneath the serosa peristaltic contractions that aid in moving the ovum through the fallopian tube
mucosa
made up of two types of cells lining the lumen. ciliated and non-ciliated. Ciliated propel the ovum toward the uterine cavity non-ciliated nourish the developing ovum as it travels through the tube on its way to the uterine cavity.
interstitial area
portion of the fallopian tube that penetrates the muscular wall of the uterus and connects the cavity of the oviduct with the uterine cavity
