Which one correctly describes the location of body parts in Pheretima?

  1. Two pairs of accessory glands in 1618 segments

  2. Two pairs of testes in 10th and 11th segments

  3. Four pairs of spemathecae in 47 segments

  4. One pair of ovaries attached over septum 1415 segments
Reveal answer Fill a bubble to check yourself
B Correct answer
Explanation

Two pairs of accessory glands are present in 17th and 19th segments. Four pairs of spermathecae are located in 6th-9th segments. They receive and store spermatozoa during copulation. One pair of ovaries is attached at the inter-segmental septum of the 12th and 13th segments.

Two pairs of testes are present on the 10th and 11th segments.
So the correct answer is 'Two pairs of testes in 10th and 11th segments'.

Part of peritoneum that suspends testes is called

  1. Mesentery

  2. Mesorchium

  3. Mesovarium

  4. Renal peritoneum
Reveal answer Fill a bubble to check yourself
A Correct answer

A mesentery is a double layer of visceral peritoneum. It connects an intraperitoneal organ to (usually) the posterior abdominal wall. It provides a pathway for nerves, blood vessels and lymphatics to travel from the body wall to the viscera.
The mesentery of the small intestine is simply called ‘the mesentery’. Mesentery related to other parts of the gastrointestinal system is named according to the viscera it connects to the mesoappendix.
So the correct answer is 'Mesentery'.

  1. Epithelial tissue

  2. Areolar tissue

  3. Dense fibrous connective tiisue
  4. Both $(1)$ and $(3)$
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

Epithelial tissues line the outer surface of organs and blood vessels throughout the body, as well as the inner surface of cavities in many internal organs. The human skin has up to seven layers of ectodermal tissues and guards the underlying muscles, Bones, etc.

The skin consist of $3$ layers of tissues, the epidermis an outer most layer the contains the primary protective structure, the stratum corneum, the dermis, a Fibrous layer that supports and strengthens the epidermis; and the subcutis.

The most abundant tissue in the body is

  1. Nervous

  2. Muscular

  3. Vascular

  4. Epithelial
Reveal answer Fill a bubble to check yourself
B Correct answer
Explanation

Skeletal muscle is the most abundant of the human body's tissue. It consists of thread-like cells, of which the longest can be up to 30cm long and 0.15mm thick, that are bound together into strands by collagen filaments. So, the muscular tissue is abundant as it has around 700 muscles, which constitutes around 40% of total body weight.
So, the correct answer is option B.
