1 Male Checklist Male Reproductive System Components of the Male
Male Checklist Male Reproductive System Components of the male Testes; accessory glands and ducts; the penis; and reproductive system the scrotum. Functions of the male The male reproductive system produces sperm cells that reproductive system can be transferred to the female, resulting in fertilization and the formation of a new individual. It also produces sex hormones responsible for the normal development of the adult male body and sexual behavior. Penis The penis functions as the common outlet for semen (sperm cells and glandular secretions) and urine. The penis is also the male copulatory organ, containing tissue that can fill with blood resulting in erection of the penis. Prepuce A fold of skin over the distal end of the penis. Circumcision is the surgical removal of the prepuce. Corpus spongiosum A spongy body consisting of erectile tissue. It surrounds the urethra. Sexual excitement can cause erectile tissue to fill with blood. As a result, the penis becomes erect. Glans penis The expanded, distal end of the corpus spongiosum. It is also called the head of the penis. Bulb of the penis The proximal end of the corpus spongiosum. Bulbospongiosus muscle One of two skeletal muscles surrounding the bulb of the penis. At the end of urination, contraction of the bulbospongiosus muscles forces any remaining urine out of the urethra. During ejaculation, contractions of the bulbospongiosus muscles ejects semen from the penis. Contraction of the bulbospongiosus muscles compresses the corpus spongiosum, helping to maintain an erection. Corpus cavernosum One of two spongy bodies consisting of erectile tissue that (pl., corpora cavernosa) form the sides and front of the penis.

The long fibroelastic penis lacks a prominent glans and is coiled at its free end to form two and one-half turns. Near the tight coils of the penis, on the right ventrolateral aspect, lies a V-shaped ventral process. The scrotum is prominent, unpigmented, and devoid of hair and is attached close to the body, high in the perineal region. The ovoid, obliquely oriented testes carry a large cauda and caput epididymis. Accessory genital glands consist of paired, lobulated, club-shaped vesic ular glands, and a pair of ovoid bulbourethral glands. A well-defined prostate gland was not observed on the surface of the pelvic urethra. Many features of the male genital organs of T. javanicus are pleisomorphic, being retained from suiod ancestors of the Artiodactyla. Key words: Tragulus javanicus, male genital organs, accessory genital glands, reproduc tion, anatomy, Malaysia The lesser mouse deer (Tragulus javan gulidae, and Bovidae (Webb and Taylor, icus), although a ruminant, possesses cer 1980).

Under the auspices of the World Association of Veterinary Anatomists (W.A.V.A.), the International Committee on Veterinary Anatomical Nomenclature (I.C.V.A.N.) appointed in Giessen, 1965, a Subcommittee on Histology and Embryology which started a working relation with the Subcommittee on Histology of the former International Anatomical Nomenclature Committee. In Mexico City, 1971, this Subcommittee presented a document entitled Nomina Histologica Veterinaria: A Working Draft as a basis for the continued work of the newly-appointed Subcommittee on Histological Nomenclature. This resulted in the editing of the Nomina Histologica Veterinaria: A Working Draft II (Toulouse, 1974), followed by preparations for publication of a Nomina Histologica Veterinaria.

The Urethral Glands of Male Mice in Relation to Depletion of Secretory Granules Upon Mating M
The urethral glands of male mice in relation to depletion of secretory granules upon mating M. B. Parr, L. R. de Fran\l=c;\a, L. Kepple, L. Ying, E. L. Parr and L. D. Russell ^Southern Illinois University, School of Medicine, Carbondale, IL 62901, USA; and institute of Biological Sciences, Federal University of Minas Gerais, Belo Horizonte, Minas Gerais, Brazil 31270-901 CP 2486 The present study describes the effects of mating on urethral gland acinar cells in male mice. Histological and morphometric analysis demonstrated that there was a depletion of secretory granules in the urethral glands during mating. However, no change occurred in the rough endoplasmic reticulum containing tubular elements. The results indicate that the urethral glands are functional during mating. The timing of their granule depletion suggests that urethral gland secretions may contribute to the formation of semen or the copulation plug.

Seminal vesicles 2-Prostate gland 3-Bulbouretheral gland/ Cowper’s gland Testis The testis remains covered by: Tunica vaginalis- The outermost covering (peritoneal covering of the testis and epididymis). It has a parietal and visceral layer. The parietal layer remains adhered to the scrotum while the visceral layer adheres to the capsule of the testis. The space between the these two layers is called the vaginal cavity. The layers consists of mesothelium lining and connective tissue that blends with the underlying connective tissue of the scrotum. Tunica albuginea: Capsule of the testis Consists of dense irregular connective tissue, predominantly collagen fibers, few elastic fibers and myofibroblast. It has vascular layer (Tunica vasculosa) that contains anatomizing branches of testicular artery and veins. The tunica albuginea gives connective tissue trabeculae called septula testis which converge towards the mediastinum testis. The septula testis divides the testicular parenchyma into number of testicular lobules. Each lobule contains 1-4 seminiferous tubules. Mediastinum testis is a connective tissue area containing the channels of rete testis, large blood and lymph vessels. In bull it occupies the central position along the longitudinal axis of the gonad. Interstitial cells (Leydig cells) The inter-tubular spaces of the testis contain loose C.T., blood and lymph vessels, fibrocytes, free mononuclear cells and interstitial cells called Leydig cells.

There is lit- tle information about the anatomy and histology of various organs of this species. Moreover, there are no practical data about the accessory male sex glands of this species of squirrel. In this study the anatomical, histological and histochemical properties of the male reproductive system accessory glands of Persian Squirrel was evaluated. Eight adult male squirrels were anesthetized and euthanized. The pelvic area was dissected and the male reproductive system was separated. The accessory sex glands were investigated for gross anatomical aspect. Samples were fixed in formaldehyde for histological and histochemical studies. The coagulating glands, prostate and bulbourethral glands were observed at gross anatomical level. A single heart- shape and compact prostate gland was situated on the dorsal side of pelvic urethra. Two small coagulating glands were observed on the cranio-dorsal side of prostate. Two large spiral shape bulbourethral glands were situated out of the pelvic cavity near the root of penis on both sides of anal area. Histologic studies revealed that all accessory sex glands were alveolar glands with cuboidal to columnar epithelium.
