Questions Related to chemical coordination and integration
The effect of different hormones on the body can be best said to bring about
-
Stimulation of organs
-
Release of inherent capacities
-
Proper growth
-
Co-ordination of functions
Hormones are our body's chemical messengers. They travel in your bloodstream to tissues or organs. They work slowly, over time, and affect many different processes, including- growth and development, metabolism that derives energy from the foods we eat, sexual function, reproduction, mood. All of these is achieved by coordination of functions. Thus, answer is- 'co-ordination of functions'.
Excess of hormones is caused due to
-
Hypersecretion
-
Hyposecretion
-
Endosecretion
-
Exosecretion
- Hypersecretion means excessive production of a bodily secretion.
- Hypersecretion - too much of any hormone in the body is caused by a secretory pituitary tumour. Hyposecretion- too little of any hormone in the body can be caused by a large pituitary tumour, which interferes with the pituitary gland's ability to produce hormones. Hence, Excess of hormones is caused due to Hypersecretion.
Term 'hormone' was coined by
-
W. M. Bayliss
-
E. H. Schally
-
E. H. Starling
-
G. W. Harris
The word "hormone" was coined by the English physiologist Ernest H. Starling in connection with the discovery of secretin, the first hormone, in 1902.
Which of the following best describes hormones?
-
Hormones are relatively unstable and work only in the area adjacent to the gland that produced them.
-
Hormones are stable, long-lasting chemicals released from gland.
-
Hormones are chemical messengers that are released into the environment.
-
All hormones are lipid-soluble.
A hormone is a regulatory chemical that is secreted into the blood by an endocrine gland or an organ of the body exhibiting an endocrine function. The blood carries the hormone to every cell in the body, but only the target cells for a given hormone can respond to it. Thus Hormones are stable, long lasting chemicals released from glands.
Which of the following is not necessarily a property of all hormones?
-
Information carrying
-
Secreted in low amounts
-
Short half-life
-
Protein in nature
All hormones in the human body can be divided into lipid-derived, amino acid-derived, and peptide hormones. They are biochemical messengers, secreted in very low amounts with considerably small half - life.
I am secretions of endocrine glands. Chemically I maybe steroids, proteins or amino acid derivatives. I am transported by blood to the reaction site. I may accelerate or inhibit specific activity. My action may be slow or quick
Who am I?
-
Hormone
-
Digestive juice
-
Enzyme
-
Water
Hormone is a regulatory substance produced in an organism by glands and transported in tissue fluids such as blood to stimulate specific cells or tissues into action.
Hormones may be
-
Steriods
-
Peptides
-
Amino acid derivatives
-
All of the above
Hypersecretion of GH from pituitary in the adult causes a
disease called
-
Gigantism
-
Acromegaly
-
Cushing's disease
-
Addison's disease
Hypersecretion of growth hormones or catastrophic hormone during adulthood causes acromegaly. Acromegaly patient has a gorilla like appearance with huge hands and legs.
An organ where a hormone shows its effect is called
-
Effector
-
Target
-
Initiator
-
Terminator
Hormone term was coined in 1905 by
-
E.H. Starling
-
G.W. Harris
-
E.H. Schally
-
None of the above
- E.H. Starling in 1905 discovered a signalling molecule or chemical secretin, from pancreatic secretions and named this signalling molecule as hormone.
- G.W. Harris is known as the father of neuroendocrinology. He worked on the neural control of endocrine system
