What is the 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.

Which type of epithelium is present in testis?

The germinal epithelium is the epithelial layer of the seminiferous tubules of the testicles. It is also known as the wall of the seminiferous tubules. The cells in the epithelium are connected via tight junctions.

What are the three 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 of a testis?

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 the function of seminiferous tubules in testis?

The seminiferous tubules are the site of spermatogenesis where germ cells develop into spermatozoa in close interaction with Sertoli cells.

What is spermatogenesis explain the process?

Spermatogenesis is the process of sperm cell development. Rounded immature sperm cells undergo successive mitotic and meiotic divisions (spermatocytogenesis) and a metamorphic change (spermiogenesis) to produce spermatozoa.

Why are Leydig cells eosinophilic?

Why are the Leydig cells eosinophilic? They contain numerous mitochondria.

What is rated testis?

The rete testis (/ˈriːti ˈtɛstɪs/ REE-tee TES-tis) is an anastomosing network of delicate tubules located in the hilum of the testicle (mediastinum testis) that carries sperm from the seminiferous tubules to the efferent ducts. It is the counterpart of the rete ovarii in females.

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 is the normal testicular volume?

12.5-19 mL 2
Normal adult testes are ovoid and measure approximately 3 cm (AP) x 2-4 cm (TR) x 3-5 cm (length), with a volume of 12.5-19 mL 2. However, the size of the testes decreases with age. From the mediastinum testis, several radiating septa extend into the testis forming 250-400 lobules.
