49.) Scrotum: Is the sac that is located below the penis and it contains the testicle. The numerous glands in the skin of the scrotum produce sweat. These responses help regulate the temperature of the testicles. The temperature in the scrotum is 2-3 degrees centigrade lower than in the interior of the body. Sperm can be produced only at a temperature several degrees lower than the normal body temperature, and any variation can result in sterility.
This complex organ can be found in upper right side of the abdomen. It is unique because it is a dual functioning organ. The first function is to control the body’s blood sugar level. The second function is to secrete insulin and glucagon. Lastly, I studied the testes of the fetal pig, which I found at the end of the scrotum under the skin. The teste are a key part in the process of secreting testosterone. After completing this section I began to dissect the last system of the pig.
Actually, urinary system is not an isolated organ and is composed of kidney, ureter, bladder and urethra. Kidney plays the role of filtering blood, during which blood and wastes are separated. Filtered blood flow out of kidney through renal vein and wastes flow
Female and males have the same goals and performance, one of their similarities are genitals. Most people distinguish Penis is male and vagina is female. However, this dichotomy isn’t quite correct because the genitals emerge from the same mass of embryonic tissue. During the first weeks of development the tissue is develop identically and when the tissues are developed the fetus either has XX or XY chromosomes and that is when the
The penis is the male organ through which sperm cells are transferred from the male to the female. The penis contains three columns of erectile tissue. Engorgement of this erectile tissue with blood causes the penis to enlarge and become firm this process is called erection. Two of the erectile columns form the dorsum and sides of the penis and are called the corpora cavernosa. The third column, the corpus spongiosum, forms the ventral portion of the penis. It expands to form a cap over the distal end of the penis. The spongy urethra passes through the corpus spongiosum, penetrates the glans penis, and opens as the external urethral orifice. At the base of
The scale of the testicles is well correlated to the synthesis functionality of the sperm and further gonadal sperm reserves [Parkinson et al., 2004]. The scrotal circumference is the best and the most sophisticated device for estimating the mass of the reproductive organs [Lino et al., 1972; Notter et al., 1987] and the level of testes development [Lunstra et al., 1978] inside the animal. The testicle circumference and histological sections were assessed to determine the efficacy of the vaccine on gonadal features. Analysis of the sub-physiological contents of testicles revealed a direct relationship between the steroid and spermatogenic production. Our research finding shows that the vaccine has a strong effect on the scrotal circumference of immunized ram lambs compared with the control ram lambs (P < 0.05). Furthermore, the microscopic histological outcomes of testicles indicate that the vaccinated ram lambs indicated lower masses of spermatogonium, spermatocytes, and spermatids. The histological observation revealed smaller seminiferous
Bulbourethral glands (Cowper's gland) are located at inferior to the prostate on either side of the membranous urethra and their ducts open into the spongy urethra. During the time of sexual arousal, the bulbourethral glands release an alkaline fluid into the urethra that guides the sperm
Pathophysiology: According to Heather and McCance 90% percent of testicular cancers are germ cell tumors, arising from the male gametes. Germ cell tumors include seminomas, embryonal carcinomas, teratomas, and choriosarcomas. Testicular tumors also can arise from specialized cells of the gonadal stroma (Leydig, Sertoli, granulosa, theca cells) although they make up only about 10% of the total cases. Non-seminomas tend to grow at a faster rate and metastasize more quickly than seminomas.
The patient was brought to the operating room and placed on the table in a supine position. After induction of adequate general anesthesia, patient was prepped and draped in a sterile fashion. Curvilinear incision was made superior and lateral to the os pubis and carried it down through the skin and subcutaneous tissue on the right. External oblique was identified and opened in direction of the fibers. Once this was done, the spermatic cord was elevated using a Penrose drain. There was a fair amount of scarring and a large lipoma of the cord, which obstructed visualization. The lipoma was carefully dissected away from the cord and the cord structures down to the level of the internal ring and then imbricated. Once this was done, the cord was inspected no evidence of
• Can pass back and forth between the scrotum and abdomen because the tube is still open (communicating hydrocele).
The first image on the left shows normal testicals that have no abnormal lumps to it that may be signs of testicular cancer, while the one on the right shows abnormal cell growth that may be benign or malignant. Testicals should have an even shape and consistency without any lumps or abnormal ridges to it, and the testies should have an egg or oval shape to
The prostate is a walnut-sized gland that lies below the urinary bladder and surrounds the urethra. Along with the seminal vesicles, the prostate gland produces a fluid, called prostatic fluid, that contains, protects, nourishes, and supports the sperm. The white, sticky fluid originally from the prostate forms most of the volume of the semen. The prostate has no known function other than reproduction.
The prostate gland produces most of the fluid that nourishes and transports sperm. It’s located just below the bladder and surrounds the urethra, through which urine passes out of the body. After puberty, the prostate is about the size of a walnut. As men age, the gland gradually increases in size (see illustration).
