What is the structure of the testes?
Each testicle is covered by tough, fibrous layers of tissue called the tunica. The outer layer is called the tunica vaginalis and the inner layer is called the tunica albuginea. The testicle is divided into parts called lobules. Each lobule contains tiny U-shaped tubes called seminiferous tubules.
What is histological structure of testis?
Histology of testis- Testis is an oval egg like structure present in the man. They are two in number. The testis is a highly complex structure which is made up of three layers called the Tunica vaginali, Tunica vasculosa and Tunica albuginea. Each testis contains several compartments called the testicular lobule.
What is the microscopic structure of the testes?
Microscopic Anatomy The testis is composed of lobules of glandular tubules. These tubules are highly convoluted and held together by loose connective tissue with interspersed groups of “interstitial cells,” which contain Leydig cells.
What are the layers of the testes?
There are three layers to the tunica, the tunica vasculosa, tunica albuginea and tunica vaginalis.
- Tunica vasculosa. The tunica vasculosa is the inner layer of the tunica and consists of blood vessels and connective tissue.
- Tunica albuginea.
- Tunica vaginalis.
What is the structure and function of the 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 producing sperm.
How many lobules does the testis have?
Abstract. In 20 autoptically obtained testes from men of various ages, 250-290 testicular lobules per testicle could be recognized by preparation with a stereomicroscope.
What is the epithelium of testis?
They are lined by simple cuboidal epithelium .
What are the major components of testis?
Anatomy and function of testes
- Seminiferous tubules. Seminiferous tubules are coiled tubes that make up most of each testis.
- Rete testis. After sperm is created in the seminiferous tubules, sperm cells travel toward the epididymis through the rete testis.
- Efferent ducts.
- Tunica: Vasculosa, albuginea, and vaginalis.
What are the two major functions of the testis?
The Testis has following three functions. First, it produces spermatozoa, the male gametes. Second, it synthesizes testosterone, the principal male sex hormone. Third, it participates with the hypothalamus-pituitary unit in regulating reproductive function.
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.
How many compartments are there in testis?
Abstract. The mammalian testis has two basic compartments: the interstitial (intertubular) compartment and the seminiferous tubule compartment (Fig. 1A). The interstitial compartment is highly vascularized and contains Leydig cells clustered near or around the vessels.
What is corpus epididymis?
Body or corpus epididymis – It is the long coiled tube, where sperms mature. Tail or cauda epididymis – It stores the mature sperm and is connected to the vas deferens.
What is the epithelium of seminal vesicle?
The seminal vesicles appear as honeycombed saccules with thin, highly branched folds of mucosa, lined by a pseudostratified columnar epithelium. These folds join one another to delimit irregular spaces, which communicate with a large, central lumen filled with a pale-staining, homogenous secretion.
