In which category of gland, secretary cells mature, rupture and becomes the secretary product.

Type Example
$1$ Holocrine gland Sebaceous gland
$2$ Exocrine gland Salivary gland
$3$ Apocrine gland Mammary gland
$4$ Merocrine gland Pancreas
  1. $1$
  2. $2$
  3. $3$
  4. $4$
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

Holocrine glands are a type of exocrine glands. They basically release their contents by rupturing, resulting in the death of the secretory cells itself and the contents are released into the lumen. For example, sebaceous glands.

So, the correct answer is '1'.

Intercellular communication in multicellular organisms occur through 

  1. Digestive system only

  2. Nervous system only

  3. Both nervous and endocrine system

  4. Respiratory system only
Reveal answer Fill a bubble to check yourself
C Correct answer
Explanation

In our body, we have 2 types of control and coordinating systems. One is through neurons, known as the nervous system and another is through hormones known as the endocrine system.

Both these systems are responsible for maintaining the overall regulatory system of the body.
So, option C " Both nervous and endocrine system" is the correct answer.

Hormones are ........... substances secreted in ........... quantities by .......... which acts on the effector organs.

  1. Electrical, large, endocrine gland

  2. Chemical, small, endocrine gland

  3. Electrical, large, exocrine gland

  4. Chemical, small , exocrine gland
Reveal answer Fill a bubble to check yourself
B Correct answer
Explanation

Hormones are organic chemical substances that are released or secreted by endocrine glands in one part of the body and sends out messages that affect cells in other parts of the body. They act as chemical messenger. The target organs or tissues are affected by and respond to only minute quantities of the hormones. Thus, only a small amount of hormone is required to alter cell metabolism. Major endocrine glands include pituitary, thyroid, parathyroids, pancreas, adrenals, testes or ovaries.

Thus, the correct answer is option B.

Which of the following is not a gland ? 

  1. Stomach

  2. Liver

  3. Kidney

  4. Pancreas
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

The glands are structures in which the cells are involved in the production of hormones or secretions. These hormones or secretions have an effect on the substrates. There are cells in the stomach which are responsible for the production of mucus, HCl, digestive enzymes, etc. There are glandular cells in the stomach but the stomach is not considered as a gland. The liver is the gland which produced various hormones, enzymes and the bile juice. The pancreas produces pancreatic juice with enzymes and hormones by the Islet cells of Langerhans. The kidney is a gland which secretes the hormones erythropoietin and renin.

Thus, the correct answer is option A.

The ductless glands in the human body which secrete hormones are called as

  1. Exocrine glands

  2. Endocrine glands

  3. Epithelial glands

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

a) Endocrine glands are the ductless glands that release their secretion (hormones) directly into the bloodstream. The released hormones affect the target cells which specifically carry their receptors.

 b) Exocrine glands release their secretions by duct into the target cells/organs only. 
c) All glands are formed by invagination or infolding of glandular epithelium and thus, are called as epithelial glands. It includes both endocrine and exocrine glands. 
d) Glands that secrete the substances which regulate the metabolic processes are known as metabolic glands. These can be both endocrine and exocrine in nature. 
So, the correct answer is option B.

Which of the following is not true?

  1. The endocrine system is composed of ductless glands.

  2. Contents of the endocrine system are released into the blood stream.

  3. The Mammary gland is part of the endocrine system.

  4. Exocrine glands are not part of the endocrine system.
Reveal answer Fill a bubble to check yourself
C Correct answer
Explanation
The mammary gland is a gland located in the breasts of females that is responsible for lactation, or the production of milk. Mammary glands are a part of exocrine system. They have ducts and hence not a part of endocrine system.

Which type of signaling mechanism is most likely used for communication between two neighboring cells?

  1. Steroid hormones

  2. Molecules released in the extracellular space

  3. Endocrine signaling

  4. Molecules released in the bloodstream
Reveal answer Fill a bubble to check yourself
B Correct answer
Explanation

  •  The extracellular ("outside of cell") ligand-binding, a hydrophobic domain extending through the membrane.
  • This type  of signaling mechanism is most likely used for communication between two neighboring cells is by extracellular space,
Hence, the type of signaling mechanism is most likely used for communication between two neighboring cells is by Molecules released in the extracellular space.
So, the correct answer is 'Molecules released in the extracellular space'.

I am gland with ducts. My secretion may be enzyme, sweat, oil or tear. My ducts transports these secretion close to the source of production. Who am I?

  1. Thyroid gland

  2. Exocrine gland

  3. Endocrine gland

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

Exocrine gland is the right answer because exocrine glands are glands with ducts unlike endocrine glands. Salivary gland, sweat gland etc are exocrine gland.
