Question

Explain, in detail, the male reproductive system of cockroach.

Answer 1

★ $\large{\underline{\rm{\blue{Male\:reproductive\:system:-}}}}$

→ A pair of testes lying one on each lateral side in the 4th - 6th abdominal segments.

• Each testis → a thin vas deferens + seminal vesicle ejaculatory duct → male gonopore.

→ Seminal vesicles:- To store sperms. Sperms are glued together in the form of bundles called spermatophores which are discharged during copulation.

→ Accessory glands:- Include a mushroom gland and phallic gland. Their secretions nourish the sperms.

→ External genitalia:- Include male gonapophysis or phallomere.

Answer 2

Heya!!

______________________________________

$\pink{\underline{\underline{\sf{Male\: Reproductive \:system}}}}$

• A pair of testes
• A pair of gas deferens
• One ductus ejaculatories.
• Mushroom gland
• Seminal vesicles
• Gonapophyses.

1) $\underline{\sf{Tests:}}$

$\bigstar$ The Male reproductive system consists of a pair of testes.

$\bigstar$ These are elongated and global structure lime one on each lateral side in the 4th to 6th abdominal segments they are embedded in the fat bodies .

2)$\underline{\sf{Vasdeferens:}}$

$\bigstar$ From the posterior end of each testis their start sitting duct the Vasdeferences .

$\bigstar$ They Run backwards and forwards to open into a wide median duct the Ducts ejaculatory areas in the seven segment .

3)$\underline{\sf{Mushroom\: Shaped\: Gland}}$

$\bigstar$ It is present in the sixth and seventh abdominal segments which functions as an accessory reproductive gland .

$\bigstar$ This gland consists of two types of tubules .....

1. Untriculi majores.
2. Untriculi breviores

utriculi majores:-

• These are long Slender tubules there also known as peripheral tubules

• Secretions of this form an inner layer of the spermatophore.

utriculi breviores:-

• These aur short to be used their secretions Nourish the sperms these two bills open into the anterior part of ejaculatory duct

4) $\underline{\sf{Seminal\:Vesicles}}$

$\bigstar$ They are present on the ventral surface of the ejaculatory duct.

$\bigstar$ These sacs store the sperms in the form of bundles called "spermatophores".

5) $\underline{\sf{Gonopore:}}$

$\bigstar$ The ejaculatory duct is a muscular tube that extends post really and opens at the Gonopore.

$\bigstar$ phallic gland also opens near the gonopore its function is not known.

6) $\underline{\sf{Phallomers}}$

$\bigstar$ Around the gonopore kitten ears asymmetrical structures are present called phallic organs.

$\bigstar$ These are the male external genital.
