Seminiferous tubule The epithelium of the tubule consists of a type of sustentacular cells known as Sertoli cells, which are tall, columnar type cells that line the tubule. In between the Sertoli cells are spermatogenic cells, which differentiate through meiosis to sperm cells.Sertoli cells function to nourish the developing sperm cells. They secrete testis-determining factor, a binding protein which increases the concentration of testosterone inside the seminiferous tubules.he seminiferous tubules are formed from the testis cords that develop from the primitive gonadal cords, formed from the gonadal ridge. Seminiferous tubule (right) with sperm (black, tiny, ovoid).

Alternative names The testes have two functions – to produce sperm and to produce hormones, particularly testosterone. Sperm are produced in the seminiferous tubules of the testes. There are about 700 of these tubes in each testis, each is the length of an arm and the width of a few hairs; the whole collection of tubules is longer than a football pitch!

testis Within the tubules are sustentacular cells, which secrete inhibin. The testes are suspended from the body by the spermatic cord, a structure that extends from the inguinal ring to the testis and contains the ductus deferens, testicular vessels (spermatic artery, vein, lymph vessels), and nerves.

- These organs deliver and receive sperm, and fertilize the egg. The Male Reproductive System The primary function of the male reproductive system is to produce and deliver sperm; produce and secrete sex hormones.Pathway for Sperm 1. Seminiferous tubule (spermatogenesis here) 2. Tubulus rectus (the straight tube) 3. Rete testis (network of vessels) 4. Efferent ductile 5.he seminiferous tubules There are a few different types of cells in the seminiferous tubues: 1. Developing sperm cells 2. Sertoli cells 3. Leydig cell (interstitial cells that produce testosterone) Glands The bulk of semen comes from vesicular fluid (2/3) and the prostatic fluid (1/3).

Testicular Torsion Testicular torsion is a twisting of the testicles and the spermatic cord (the structure extending from the groin to the testicles that contains nerves, ducts, and blood vessels). The torsion causes decreased blood flow to the testicles, essentially strangling them of oxygen and nutrients.

Sperm Cell The third and final component of the sperm cell is the propulsion system. It is the whip-like structure of the sperm tail. It serves the important function of propelling the sperm cell forward with a snake-like motion.It is critical that sperm move forward and not laterally or in circles.he sperm cell is then able to enter into the main part of the egg, the ooplasm, achieving successful fertilization. The second component of the sperm cell is the energy source. Think of this as the rocket's fuel tank, its sole purpose is to convert nutrients into energy.

- Sperm cells that are stored in the male body are not capable of self-movement because of the acidity of the accompanying fluids. When the sperm receive fluids, called seminal plasma, from the various internal accessory organs (prostate gland, ejaculatory ducts, seminal vesicles, and bulbourethral glands []), the acidity decreases. As they leave the body, the sperm receive oxygen, which is vital to motility.

Sperm motility The tail of the sperm-the flagellum-confers motility upon the sperm, and has three principal components: 1  a central skeleton constructed of 11 microtubules collectively termed the axoneme and similar to the equivalent structure found in cilia. 2  a thin cell membrane covering the axoneme.

The Male Reproductive System Testicles (testes) — The testes are oval organs about the size of very large olives that lie in the scrotum, secured at either end by a structure called the spermatic cord. Most men have two testes. The testes are responsible for making testosterone, the primary male sex hormone, and for generating sperm.esticles (testes) — The testes are oval organs about the size of very large olives that lie in the scrotum, secured at either end by a structure called the spermatic cord.

What Are 3 Functions of the Umbilical Cord? The umbilical cord is a connection between the mother and the developing fetus. The umbilical cord has three functions for the developing fetus: it supplies oxygen, it delivers nutrients, and it helps to withdraw blood rich in carbon dioxide and depleted in nutrients. Blood from the umbilical cord can also be used to treat a variety of diseases, much like bone marrow.

Testes Click to read more below. The testes (singular: testis), commonly known as the testicles, are a pair of ovoid glandular organs that are central to the function of the male reproductive system. The testes are responsible for the production of sperm cells and the male sex hormone testosterone. The testes produce as many as 12 trillion sperm in a male's lifetime, about 400 million of which are released in a single ejaculation. Located in the hollow sac of the scrotum, each testis is about 1.5 to 2 inches long along its long axis and around 1 inch in diameter....

Testicular Torsion It runs from the abdomen to the testicle, and connects to the testicle in the scrotum (external sac). Also called testicular cord. Testicles (Testes). One of two egg-shaped glands inside the scrotum that produce sperm and male hormones.Also called testicle.esticular Torsion. Testicular torsion occurs when the spermatic cord (from which the testicle is suspended) twists, cutting off the testicle's blood supply. The principal symptom is testicular pain. The testis is inadequately affixed to the scrotum, allowing it to move freely. PubMed Health Glossary. (Source: Wikipedia).

Testicular Torsion Within the scrotum, the testicles are secured by a structure called the spermatic cord, which contains an anchoring tissue called the gubernaculum at the lower part of the testicle. Sometimes, this cord gets twisted around a testicle, cutting off the blood supply.ymptoms of testicular torsion include sudden and severe pain, enlargement of the affected testicle, tenderness, and swelling.

Testes The immature sperm cells are supported and protected by Sertoli cells as they travel the length of the seminiferous tubules and slowly mature. Leydig cells at the ends of the seminiferous tubules produce the male hormone testosterone that produces the secondary sex characteristics associated with males.

umbilical cord A ropelike structure that connects a developing embryo or fetus to the placenta. The umbilical cord contains the blood vessels that supply the embryo or fetus with nutrients and remove waste products. Connected to the abdomen of the embryo or fetus, the umbilical cord is cut at birth, leaving a small depression — the navel, or “belly button.”.

Testicle The testicle or testis is the male reproductive gland in all animals, including humans. It is homologous to the female ovary. The functions of the testes are to produce both sperm and androgens, primarily testosterone. Testosterone release is controlled by the anterior pituitary luteinizing hormone; whereas sperm production is controlled both by the anterior pituitary follicle-stimulating hormone and gonadal testosterone.

Testicular Torsion Background. Testicular torsion refers to the torsion of the spermatic cord structures and subsequent loss of the blood supply to the ipsilateral testicle. This is a urological emergency; early diagnosis and treatment are vital to saving the testicle and preserving future fertility.
