Biology Lab Fetal Pig Dissection Part 1 Youtube Using dissection techniques, we have examined the internal anatomy of a frog, a perch, a sea star, an earthworm, and a crayfish. now we will turn our attenti. 1. before you start dissecting, examine the outside of the pig and determine its sex. look for these features: males: the urogenital opening is located near the umbilicus; the penis is hidden inside. the scrotal sac may be visible as a swelling just ventral to the anus, depending on the age of the fetus.

Obtain a fetal pig and identify the structures listed in figure 1. use figures 1–4 below to identify its sex. use your pig and also a pig of the opposite sex to identify the structures in the photographs below. the word “urogenital” refers to an opening that serves both the urinary (excretory) and the reproductive systems. Positioning the pig for dissection. place the fetal pig on a dissecting tray ventral (belly) side up. use two or three rubber bands to tie the right hind leg around the ankle. run the rubber bands around the underside of the tray and tie the left hind leg. repeat for the forelegs.
