What is testicular morphology?
The testes are tubular and can be subdivided into three histologically distinct parts: anterior, intermediate and posterior. The anterior part of the testes is composed of a convoluted seminiferous tubule surrounded by hemal sinuses. The seminiferous tubules are lined externally by a simple squamous epithelium (Fig.
What are the three types of cells in the testes?
The testes contain germ cells that differentiate into mature spermatozoa, supporting cells called Sertoli cells, and testosterone-producing cells called Leydig (interstitial) cells.
What is difference between testis and testes?
Testicle or testis (plural testes) is the male reproductive gland or gonad in all animals, including humans. It is homologous to the female ovary.
What are the two cells in the testes?
The testicles make sperm and male hormones. The 2 main types of cells in the testicles that perform these functions are germ cells and stromal cells.
What is the function of testis?
Testicles (testes) The testes are responsible for making testosterone, the primary male sex hormone, and for producing sperm. Within the testes are coiled masses of tubes called seminiferous tubules. These tubules are responsible for producing the sperm cells through a process called spermatogenesis.
What is the function of the left testicle?
The main function of the testes is producing and storing sperm. They’re also crucial for creating testosterone and other male hormones called androgens. Testes get their ovular shape from tissues known as lobules. Lobules are made up of coiled tubes surrounded by dense connective tissues.
What is the function of testis Class 10?
Testes are the male reproductive organs. It occurs in a pair. It produces sperm and testosterone which is a male sex hormone and is produced at the time of puberty. Because of testosterone production, many sexual changes take place in a male body.
What are the functions of testis?
What are the function performed by testis in human beings?
The testes have two functions – to produce sperm and to produce hormones, particularly testosterone. Sperm are produced in the seminiferous tubules of the testes.
What are the functions of testis Class 10?
What are the two functions of testis and ovary?
(i) Functions of testis: (a) Formation of sperms by the process of spermatogenesis. (b) Secretion of testosterone hormone. (ii) Functions of ovary: (a) Formation of ova by the process of oogenesis. (b) Secretion of female hormones like estrogens, progesterone and relaxin.
Which is the first function of the testes?
The first function of the testes is to produce testosterone. Testosterone is a steroid hormone that is responsible for sexual differentiation of the male. It is important for prenatal development.
How are the testes enclosed in the scrotum?
The testes are enclosed in the tunica albuginea. This fibrous capsule surrounds the testes and also divides it into the lobules that contain the seminiferous tubules. The whole mass is then mostly surrounded by the tunica vaginalis. This covering allows the testes to move smoothly inside the scrotum.
What does it mean when both testes are on the same side?
Transverse testicular ectopia, or crossed testicular ectopia, is a rare condition. It occurs when both testicles descend to the same side of the scrotum, instead of each descending into their own side of the scrotum.
Can a man have more than three testicles?
People with polyorchidism most commonly have three testicles, but men with as many as five testicles have been identified. 4 Polyorchidism is a very rare condition, diagnosed in fewer than 200 individuals. Transverse testicular ectopia, or crossed testicular ectopia, is a rare condition.
