Male genitourinary system diagram
Diagram of the male reproductive system. The male reproductive system consists of two parts: the internal genitalia and the reproductive organs. The internal genitals consist of the location of the prostate (male testicles), the ejaculatory ducts (epididymal cyst, ejaculatory duct, vas deferens and urethral opening) and accessory glands (seminal vesicles, male prostate, bulbourethral glands). Reproductive organs include the vagina and male genitals. So, what are the diagrams of the male reproductive system? Let’s briefly understand and understand this issue. I hope the following points will be helpful to everyone!
1. Internal genitals:
(1) The location of the prostate: The male testicles are located in the vagina, one above and one below. An oblate ellipsoid is divided into upper and lower parts, inner and outer edges, and front edge. The surface layer is coated with high-density connective tissue called tunica albuginea. At the edge of the testicle, the tunica albuginea thickens and breaks into the testicular substance to form radial septa, which separates the testicular substance into many cone-shaped testicular lobules, each of which contains 2-3 seminiferous tubules. There are interstitial cells in the connective tissue in the middle of the seminiferous tubules that can metabolize male hormones. The seminiferous tubules converge into straight seminiferous tubules at the tips of the male testicular lobules and then intertwine with each other to form a network. Finally, more than ten efferent tubules are sent out from the edge of the male testis into the epididymal cyst.
(2) Ejaculation pipeline:
1. Epididymal cyst
Epididymal cysts are located close to the top and edge of the male testicles and can be divided into three parts: head, body and tail. The head is composed of efferent tubules, and the tail end of the efferent tubules is connected to an epididymal duct. The epididymal tube is about 4-5 meters long and consists of the body and the tail. effect
(3) Accessory glands:
1. Seminal vesicle
A flat oval sac-shaped human organ located behind the bladder base and on both sides of the ampulla of the ejaculatory duct. Its metabolic duct and the tail end of the ejaculatory duct form the vas deferens. 2. Male prostate
2. Reproductive organs:
1.YinxiangIt is a sac composed of skin. There are many smooth muscle fibers in the subcutaneous tissue, called the panniculus carnosus, which forms the pudendal septum on the middle network to separate the testicles and epididymal cysts on both sides. Its skin is a fleshy membrane composed of smooth muscle and connective tissue, which shrinks the left ventricle to adjust the temperature within the capsule. The vaginal cavity is lower than body temperature, which is of great significance to the growth and survival of male sperm. Sperm cells are more sensitive to temperature, so when the body temperature rises, the scrotum contracts to the left ventricle, which is helpful to reduce the temperature of the scrotum bones; when the body temperature drops, the scrotum contracts to store the temperature in the scrotum.
2. Male genitals
It can be divided into three parts: glans penis, male genital body and male genital root. There is an annular coronal groove between the head and body parts. The glans penis is the large part that develops at the front of the male genitalia. The tip has the external opening of the urethra, and the slightly thinner part behind the head is called the genital neck. The male genitals are composed of two corpus spongiosum and a urethral corpus cavernosum, and the outer part is composed of muscle fascia and skin. The urethral cavernous body has a urethral orifice surrounding its entire length. The front end is enlarged, which is the glans of the penis, and the back end is enlarged to produce the urethral orifice. The outside of each corpus cavernosum is covered with a layer of fiber membrane. Inside the corpus cavernosum there is a posterior capsule composed of connective tissue and smooth muscle. The space between the posterior capsules is called the cavernous body cavity. The cavernous body cavity communicates with blood vessels. If the hematoma in the cavernous body and the corpus cavernosum become enlarged, the genitals will be erect. Muscles adhere to the root of the corpus cavernosum of the penis, helping with urination, genital erection and ejaculation. The skin of the male genitals is thin and easy to flex and stretch, making it suitable for genital erection. The skin from the body of the male genitals to the neck spreads forward to form a ring-shaped wrinkled wall surrounding the head of the male genitals, which is called the foreskin of the penis.
