Watered-down, fat-free milk

Ejecting fluid during sexual activity and orgasm is not usual for females. However, two physiologic (normal processes) have been described, squirting/gushing and female ejaculation. Squirting/gushing refers to the expulsion of a relativity large volume of clear fluid through the urethra (the tube that carries urine out of the body); this fluid originates from the urinary bladder and resembles diluted urine biochemically.
Female ejaculation refers to the passage of a white scanty fluid originating from the female prostate that resembles watered-down, fat-free milk; biochemically female ejaculate resembles semen except that it does not contain sperms.
The female prostate - previously called Skene’s paraurethral gland – surrounds the female urethra and empties into it or just beside it; about half to two thirds of women have a female prostate.

Pancake brain

The front part of the brain, the forebrain also known as the prosencephalon normally separates into two halves (cerebral hemispheres) during the development of the unborn baby. Failure of the prosencephalon to separate leads to the rare disease, holoprosencephaly (HPE). The prosencephalon may fail to separate to different extents; where failure to separate is complete, alobar HPE results, which is the most severe form of HPE. The brain in alobar HPE resembles a pancake – pancake brain.
Instead of the normal two fluid-filled cavities in the front of the brain, in alobar HPE there is a single abnormal fluid-filled cavity; facial malformation frequently complicates HLE.
Cyclopia, arhinencephaly and DeMyer sequence are some of HPE’s synonyms.
