A pointed or cone-shaped structure or part.
- p. breed structure — a standard format for a multiple herd system comprising a breed structure; headed by an open or closed nucleus, a second tier of multiplier herds and a terminal tier of commercial herds which produce the end-product to be marketed. The nucleus, perhaps one herd, produces all of the basic genetic material and supplies breeding stock to the multiplier herds which have the prime role of multiplying the progeny for supply to commercial herds who produce the end product. The entire system is under the control of one organization. Ideally suited to the pig industry.
- p. of cerebellum — pyramid of vermis.
- p. of light — a triangular reflection seen upon the tympanic membrane.
- malpighian p's — renal pyramids.
- p's of the medulla oblongata — either of two rounded masses, one on either side of the median fissure of the medulla oblongata.
- renal p's — the conical masses constituting the medulla of certain kidneys, the base toward the cortex and culminating at the summit in the renal papilla.
- p. of tympanum — the hollow elevation in the inner wall of the middle ear that contains the stapedius muscle.
- p. of vermis — the part of the vermis cerebelli between the tuber vermis and the uvula.
