What is the Mesorchium?

Medical Definition of mesorchium

: the fold of peritoneum that attaches the testis to the dorsal wall in the fetus.

What is the function of the mesorchium?

- Mesorchium: It is found as a layer in testes and helps in attaching vascular and avascular structures of spermatic cord. - Mesovarium: It is a broad ligament of the uterus which suspends the uterus and does not cover the ovaries.

What is mesorchium in testes?

Mesorchium is the fibrous sheath which attaches vascular and avascular structures of spermatic cord together.

What is meant by mesorchium?

[ mə-zôr′kē-əm ] n. A fold of tunica vaginalis testis in the fetus supporting the mesonephros and the developing testis. A fold of tunica vaginalis testis in the adult between the testis and epididymis.

What is mesorchium in frog?

Mesorchium is the peritoneal fold that connects the testes and kidney in the frog.

What does mesorchium mean?

What is Mesovarium in zoology?

The mesovarium is the portion of the broad ligament of the uterus that suspends the ovaries. The ovary is not covered by the mesovarium; rather, it is covered by germinal epithelium.

What is bidder Canal?

The bidder's canal is found inside the kidney of a male frog. It receives sperms from testes via a number of vasa efferentia. The testis of the frog is very close to the bidder canal. The bidder's canal carry the sperms.

What is mesorchium and Mesovarium?

As nouns the difference between mesorchium and mesovarium

is that mesorchium is (anatomy) the fold of peritoneum that attaches the testis to the dorsal wall of the body cavity or scrotal sac while mesovarium is (anatomy) the portion of the broad ligament of the uterus that covers the ovaries.

What is peritoneum mesorchium?

A peritoneal covering is a layer that forms the lining of abdominal cavity. Mesorchium is fold of fibrous sheath of Tunica vaginalis. Tunica vaginalis is the outer covering of testis. Hence, mesorchium is peritoneal covering of Testis.

Where is the Mesosalpinx?

Serous layer of the Fallopian tube, also known as mesosalpinx (Fig. 2A), is the outer tissue layer that wraps around the Fallopian tube and is part of the peritoneal cavity lining. Mesosalpinx is composed of epithelial cells of mesothelium and a mesh of serous membrane lining (interstitial connective tissue).

Is mesorchium part of the spermatic cord?

The anatomic spermatic cord for each testis is comprised of the mesorchium and visceral tunic containing the testicular artery, vein, lymphatics, and plexus of nerves (located at the cranial aspect of the cord), and the mesoductus deferens and visceral tunic containing the ductus deferens and its vessels (at the caudal ...

Is seminoma malignant?

Seminoma is a malignant germ cell tumor that involves most commonly the testicle or less frequently the mediastinum, the retroperitoneum, or other extra-gonadal sites. They are common among men ages 15-34 years old.

What is the vaginal process?

The vaginal process (or processus vaginalis) is an embryonic developmental outpouching of the parietal peritoneum. It is present from around the 12th week of gestation, and commences as a peritoneal outpouching.

What adds fluid to sperm?

Located at the base of the bladder, the two seminal vesicles secrete a thick fluid that nourishes the sperm.

How does the Pampiniform plexus regulate temperature?

The pampiniform plexus helps regulate the temperature of the testes by acting as a “heat exchange” mechanism to cool down the blood. The arteries supplying the testes run through the plexus where the blood is cooled from abdominal arterial temperature to testicular temperature.

What is the peritoneum?

Your peritoneum is the tissue that lines your abdominal wall and covers most of the organs in your abdomen. A liquid, peritoneal fluid, lubricates the surface of this tissue. Disorders of the peritoneum are not common. They include: Peritonitis - an inflammation of the peritoneum.

What are the layers of the 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 mediastinum testis?

Medical Definition of mediastinum testis

: a mass of connective tissue at the back of the testis that is continuous externally with the tunica albuginea and internally with the interlobular septa and encloses the rete testis.

What is Epoophoron and Paroophoron?

The epoophoron is a homologue to the epididymis in the male. While the epoophoron is located in the lateral portion of the mesosalpinx and mesovarium, the paroophoron (residual remnant of that part of the mesonephric duct that forms the paradidymis in the male) lies more medially in the mesosalpinx.

What is the mesometrium?

The mesometrium is the mesentery of the uterus. It constitutes the majority of the broad ligament of the uterus, excluding only the portions adjacent to the uterine tube (the mesosalpinx) and ovary (the mesovarium). It is adjacent to the mesosalpinx. The ureter is among the structures found in the mesometrium.

Is ovarian ligament and mesovarium same?

The portion of the broad ligament supporting the ovary is the mesovarium. The mesosalpinx attaches to the uterine tube, and the mesometrium attaches to the uterus, including the uterine horn.

Do frogs Have bidders Canal?

Bidder's canal is present in male frogs. Vasa-efferentia opens into the Bidder's canal and the Bidder's canal is connected to longitudinal collecting tubules by means of a number of transverse collecting ducts and helps in the passing of the sperms. So, the correct answer is option B.

What is copulatory pad in frogs?

Copulatory pads or thumb pads are present in the forelimbs of male frog only, which helps to hold the female frog tightly underneath its body during copulation. The Frogs takes a long time to become sexually excited, as they are cold-blooded animals and devoid of copulatory organs.

What is the function of a frog's cloaca?

In fish, birds and amphibians, the cloaca -- also known as the vent -- serves as the exit cavity for the excretory, urinary and reproductive systems. Male and female frogs both have cloacas, which their respective reproductive tracts use as the vehicle for the passage of sperm and eggs.
