Homosexual Behavior In Sheep
Homosexual behavior in sheep has been well documented and studied. The domestic sheep (''Ovis aries'') is the only species of mammal except for humans which exhibits exclusive homosexual behavior. "About 10% of rams (males) refuse to mate with ewes (females) but do readily mate with other rams." Thirty percent of all rams demonstrate at least some homosexual behavior. One report on sheep found that 8% of rams exhibited homosexual preferences—that is, even when given a choice, they chose male over female partners. This documented homosexual preference has garnered much discussion. Such rams prefer to court and mount other rams only, even in the presence of estrous ewes. Moreover, around 18–22% of rams are bisexual. Several observations indicate that male–male sexual preference in rams is sexually motivated. Rams routinely perform the same courtship behaviors (including foreleg kicks, nudges, vocalizations, anogenital sniffs and flehmen) prior to mounting other males as obs ...

Sexually Dimorphic Nucleus
The sexually dimorphic nucleus (SDN) is an ovoid, densely packed cluster of large cells located in the medial preoptic area (POA) of the hypothalamus which is believed to be related to sexual behavior in animals. Thus far, for all species of mammals investigated, the SDN has been repeatedly found to be considerably larger in males than in females. In humans, the volume of the SDN has been found to be 2.2 times as large in males as in females and to contain 2.1 times as many cells. The human SDN is elongated in females and more spherical in males. No sex differences have been observed in the human SDN in either cell density or mean diameter of the cell nuclei. The volume and cell number of the human SDN considerably decreases with age, although the decrease in cell number is both sex and age-specific. In males, a substantial decrease in the cell number of the human SDN was observed between the age of 50–60 years. Cell death was more common in females than males, especially amo ...

Ovis Ammon Musimon 7zz
''Ovis'' is a genus of mammals, part of the Caprinae subfamily of the ruminant family Bovidae. Its seven highly sociable species are known as sheep or ovines. Domestic sheep are members of the genus, and are thought to be descended from the wild mouflon of central and southwest Asia. Terminology Female sheep are called ''ewes'', males are called ''rams'' or less frequently ''bucks'' or ''tups'', neutered males are called ''wethers'', and young sheep are called ''lambs''. The adjective applying to sheep is ''ovine'', and the collective term for sheep is ''flock'' or ''mob''. The term ''herd'' is also occasionally used in this sense, generally for large flocks. Many specialist terms relating to domestic sheep are used. Characteristics Sheep are fairly small compared to other ungulates; in most species, adults weigh less than .Nowak, R. M. and J. L.

Veterinary Record
''Veterinary Record'', branded as ''Vet Record'', is a semi-monthly peer-reviewed medical journal covering the field of veterinary medicine. It is published by Wiley on behalf of the British Veterinary Association and is distributed to its members as part of their membership. It was established in 1888. History The journal was established in July 1888 by William Hunting, who is said to have started the journal with loans of £50 from another London veterinary surgeon, T. A. Dollar, which he never repaid, and £20 from Dollar's son, J.A W. Dollar. Although '' The Veterinarian'' (1828) and '' The Veterinary Journal'' (1844) were well established and covered some of the same ground as Hunting's new journal, the fact that ''Veterinary Record'' was published every week and carried verbatim reports of council and local association meetings gave it an immediacy that the other publications could not match. The National Veterinary Medical Association of Great Britain and Ireland took o ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Ovary
The ovary () is a gonad in the female reproductive system that produces ova; when released, an ovum travels through the fallopian tube/ oviduct into the uterus. There is an ovary on the left and the right side of the body. The ovaries are endocrine glands, secreting various hormones that play a role in the menstrual cycle and fertility. The ovary progresses through many stages beginning in the prenatal period through menopause. Structure Each ovary is whitish in color and located alongside the lateral wall of the uterus in a region called the ovarian fossa. The ovarian fossa is the region that is bounded by the external iliac artery and in front of the ureter and the internal iliac artery. This area is about 4 cm x 3 cm x 2 cm in size.Daftary, Shirish; Chakravarti, Sudip (2011). Manual of Obstetrics, 3rd Edition. Elsevier. pp. 1-16. . The ovaries are surrounded by a capsule, and have an outer cortex and an inner medulla. The capsule is of dense connect ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
