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
