  • Sonography of the Scrotum
    1 Sonography of the Scrotum Chee-Wai Mak and Wen-Sheng Tzeng Department of Medical Imaging, Chi Mei Medical Center, Tainan, Taiwan Central Taiwan University of Science and Technology, Taichung, Taiwan Chung Hwa University of Medical Technology, Tainan, Taiwan Republic of China 1. Introduction Although the development of new imaging modality such as computerized tomography and magnetic resonance imaging have open a new era for medical imaging, high resolution sonography remains as the initial imaging modality of choice for evaluation of scrotal disease. Many of the disease processes, such as testicular torsion, epididymo-orchitis, and intratesticular tumor, produce the common symptom of pain at presentation, and differentiation of these conditions and disorders is important for determining the appropriate treatment. High resolution ultrasound helps in better characterize some of the intrascrotal lesions, and suggest a more specific diagnosis, resulting in more appropriate treatments and avoiding unnecessary operation for some of the diseases. 2. Imaging technique For any scrotal examination, thorough palpation of the scrotal contents and history taking should precede the sonographic examination. Patients are usually examined in the supine position with a towel draped over his thighs to support the scrotum. Warm gel should always be used because cold gel can elicit a cremasteric response resulting in thickening of the scrotal wall; hence a thorough examination is difficult to be performed. A high resolution, near-focused, linear array transducer with a frequency of 7.5 MHz or greater is often used because it provides increased resolutions of the scrotal contents. Images of both scrotum and bilateral inguinal regions are obtained in both transverse and longitudinal planes.

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.

  • Male Reproductive System First Lecture
    Male Reproductive system First lecture Dr. Ahmed Nazar Abduljawad The male reproductive system consists of (a) the testes surrounded by the tunica vaginalis and the testicular tunics, (b) the epididymides, (c) the ductus deferens, (d) the accessory glands (glandular portion of the ductus deferens, vesicular and bulbourethral glands, prostate), (e) the urethra, and (f) the penis surrounded by the prepuce. Testis: paired ovoid organs, serve both exocrine (sperm production) and endocrine (testosterone production) functions, suspended in the scrotum. *Scrotum: skin pouch contains sweat and sebaceous gland , scrotum maintains the testes at a temperature about 2 to3 Cº below body temperature. Tunica dartos is a special layer of smooth muscle within the scrotum, it's arranged randomly, these muscle fibers play an important role in the regulation of testicular temperature. *Capsule of testis consist of three tunics: 1.Tunica vaginalis: consists of mesothelium and a connective tissue layer that blends with underlying connective tissue of the scrotum, tunica vaginalis consist of visceral layer and parietal layer, When the testis is removed from the scrotum, the parietal layer of the tunica vaginalis remains attached to the inner surface of the scrotum, while the visceral layer, remains associated with the (tunica albuginea) of the testis. 2. Tunica Albuginea: Is a solid capsule of dense irregular connective tissue. It consists of collagen fibers, a few elastic fibers, the tunica albuginea is continuous with connective-tissue trabeculae to formed the testis trabeculae or called septula testis. The septula testis divide the testicular parenchyma into a varying number of testicular lobules, each lobule containing one to four convoluted seminiferous tubules.
