Parts of Uterine Tube 1. Intramural or interstitial (1.25cm) in length, 1mm diameter. 2. Isthmus (3-4cm), 2 mm in diameter 3. Ampulla (common site for fertilization; length 5cm) 4. Infundibulum (1.25cm); wide part Diameter 6mm Distal end of infundibulum; fimbriae
Fallopian tube (uterine tube/ Oviduct) Fallopian tube is also known as uterine, Oviduct Paired structure tube, that connect ovaries to uterus. Length; 10cm long Uterine tube has two opening; One is communicating with uterine cavity; uterine opening (1mm in diameter) and other is end of tube called pelvic opening or abdominal ostium (2mm in diameter). Parts of Uterine Tube 1. Intramural or interstitial (1.25cm) in length, 1mm diameter. 2. Isthmus (3-4cm), 2 mm in diameter 3. Ampulla (common site for fertilization; length 5cm) 4. Infundibulum
Two Mullerian Duct Embryonic structure in female, develop to form fallopian tube, uterus, cervix, upper one third of vagina. Walffian duct (mesonephric duct) Embryonic structure in male, rise male reproductive organ and kidney.
Endometrium Endometrium; inner layer, uterine layer Mucus lining cavity called endometrium, shed during menstrual cycle. It contains endometrial glands, vessels, nerves. Layers of Endometrium Layers of endometrium are; 1. Stratum compactum 2. Stratum spongiosum 3. Stratum basalis Endometrium layer divided into Two layer; 1. Functional layer 2. Basal layer 1. Functional layer It is site of proliferation, secretion and degeneration. 2. Basal layer Regenerative endometrium after menstrual loss of functionalis. Endometrium – Changes to (Decidua) during pregnancy.

Layers of Uterus Body consist three layers; 1. Parametrium (perimetrium) 2. Myometrium 3. Endometrium 1. Parametrium Parametrium is also known as perimetrium It is outer layer. It is protective layer. 2. Myometrium; Myometrium is middle layer. Thick bundle of smooth fibres held by connective tissue. Arranged in; Outer longitudinal Middle interlacing Inner circular Myometrium layer expand during pregnancy and contract to push baby out. 3. Endometrium; inner layer, uterine layer Mucus lining cavity called endometrium, shed during menstrual cycle. It contains endometrial glands, vessels, nerves.
Parts of Uterus 1. Body or Corpus 2. Isthmus 3. Cervix 1. Body or Corpus Fundus; Uppermost part, widest part of uterus. Lie above opening of uterine tube. It connects to fallopian tube. Body lie between the opening of uterine tube and isthmus Corpus where fertilized egg implant during pregnancy. 2. Isthmus Constricted part, between body and cervix (0.5cm). Below internal OS lie between corpus and cervix (narrow part of uterus). 3. Cervix Mainly composed of fibrous connective tissue. Cervix open to vagina. Extends from
Uterus Uterus is hollow pyriform (pear shaped muscular organ). Location; Situated in pelvis between bladder infront and rectum behind. Postion of uterus; normal position of uterus is Anteverted uterus. Measurement of Uterus 8cm long, 5cm wide at fundus, wall thickness 1.25cm Weight; 50-80gm Parts of Uterus 1. Body or Corpus 2. Isthmus 3. Cervix 1. Body or Corpus Fundus; Uppermost part, widest part of uterus. Lie above opening of uterine tube. It connects to fallopian tube. Body lie between the opening of uterine tube and
Vagina/ Birth canal Vagina is called birth canal. It is fibromusculo-membraneous sheath. It communicating uterine cavity and exterior at vulva. It excretory channel for uterine secretion and menstrual blood and also called birth canal of parturition (child birth/labour/delivery). Diameter of Canal About 2.5cm widest in upper part. Narrowest in lower part (entrance). Location Urethral opening at the top. Vaginal opening is in middle. Anus opening at bottom. Vagina is located between bladder and rectum. Wall of Vagina Wall of vagina made of muscle covered in
Internal genital organs of Female 1. Vagina/birth canal 2. Uterus/womb 3. Fallopian tube/ Uterine tube/ Oviduct/ Salpinges 4. Ovaries/ female gonad
