• p. bulb — a swelling at the origin of the corpus spongiosum penis.
• p. crura — the origins of the corpus cavernosum penis at the ischial arch.
• p. deviation — a common defect only in bulls in which an abnormality of the apical ligament, present congenitally or caused by trauma, causes a spiral, lateral or ventral deviation of the penis, causing difficulty in mating. See also corkscrew penis.
• p. erection — see erection.
• p. eversion — see penile prolapse (below).
• p. frenulum — see penile preputial frenulum.
• p. glans — see glans penis.

• p. sigmoid flexure — the S-shaped bend in the penis of ruminants and pigs, present when the penis is not erect, and the principal mechanism for reducing the length of the organ in these species.
• p. tiedown — an adhesion of the penis to the prepuce created artificially to prepare the animal as a teaser.
