Parts are: Interstitium (Intramural): 1.25 cm long and 1 mm diameter (narrowest part). It has no longitudinal muscles; only circular muscles are present and acts as anatomical sphincter. Isthmus: 2.5 cm long and 2 mm in diameter (second narrowest part); acts as physiologic sphincter. Ampulla: Widest and longest part (5 cm) and fertilization occurs here. Fimbriae/infundibulum: 1.25 cm long with a maximum diameter of 6 mm Total length = 4 inches or 10–12 cm. Reference: Chapter 1, page 8, JB Sharma textbook of Gynecology

The glands of labia minora are homologous to the glands of littre (glandulas prepuciales) of the penile portion of the male urethra Skene's Tubules Skene's tubules are the paraurethral glands equivalent to prostrate in males. Both Bartholin's glands and Skene's tubules arise as downgrowths of urogenital sinus. Bartholin's Glands Bartholin's Glands are homologous to Cowper's gland/bulbourethral glands in males. They are 2 in number and of racemose type. Lie in the superficial perineal pouch embedded in the posterior part of vestibular bulb. Glands are oval in shape and are the size of a pea. They are impalpable unless enlarged. The acini is lined by a single layer of low columnar or cuboidal cells. Reference: Shaw, 15/e, page 8

In adult females, vagina is lined by stratified squamous epithelium. In newborn females, it is lined by transitional epithelium. Squamous epithelium is resistant to gonococcal infection. Thus, gonococcal vaginitis cannot occur in young/adult females. Reference : J B Sharma, Textbook of Gynecology 1 st edition pg 327

Structurally, the labia minora are composed of connective tissue with many small vessels, elastin fibers, but very little smooth muscle. Nerve fibers are numerous. The epithelia of the labia minora differ by location. Thinly keratinized stratified squamous epithelium covers the outer surface of each labium. Medial to this line, each labium is covered by squamous epithelium that is nonkeratinized. Labia minora lack hair follicles, eccrine glands, and apocrine glands but have many sebaceous glands.

Uterine blood flow in nonpregnant females = 50 ml/min Uterine blood flow in pregnant females = 750 ml/min Reference: Dutta 8/e

If the dose is more than 50 ml (each ml has 50 mg of iron i.e. 2500 mg iron), then half the dose is given on day one and second half on next day. Thus maximum iron which can be given in a day is 2500 mg. ACOG recommends the use of iron sorbitol as it is safer than iron dextran. Reference: Dutta Obs. 7/e, p 269

The maximum recommended dose of oral labetalol is generally 2,400 mg per day. This is typically divided into two to three doses throughout the day. However, dosing may vary based on individual patient needs and specific clinical situations. Reference : Arias 5 th edition pg no 195

Therapeutic range = 4-7m Eq/L Disappearance of patellar reflex is the first sign of impending toxicity of MgSO4. Patellar reflex is lost when Mg++ concentration reaches 10 mEq/L.-12 mEq/L (12 mg/dl). Respiratory depression occurs with Mg concentration >12 mEq/L and arrest when >15 mEq/L. Cardiac arrest occurs when >30 mEq/L Reference : Arias 5th edition pg no 199 Reference : Arias 5 th edition pg no 198
