BRIEF REVIEW OF RECEPTORS IN HUMAN BODY

RECEPTORS IN MAN:

Receptors are the sensory organs which receive a stimulus. Following are the main receptor organs in man:

  • Organ of sight.
  • Organ of hearing.
  • Organ of smell.
  • Organ of taste.
  • Organ of touch.



Sight:

The eyes are the most marvelous of the sense organs as they make us aware of various objects around us, nearby and far away. When we see a tree we don’t have to touch it or climb its branches in order to know what it is like. With normal vision we can reach out as far as our eyes can see and are thus becoming aware of events and circumstances around us. These eyes are the great bliss of Almighty Allah.

Ears:

The ears are the most amazing and spectacular organs in our body. These are one of the best endowed by Allah. The ears lend a hand us to hear everything we want. There are frequency ranges, but human ear can only hear in the frequency range between 20Hz to 20,000Hz. This is called audible frequency.

Smell:

The organ of smell lies in the nasal cavity above mouth. It is also called the olfactory organ and its sensitive cells are supplied by the branches or the olfactory nerve from the brain. The incoming air currents carry the smell particles of substances into the nasal cavity which arouse the sensitive cells in the organ of smell. The olfactory nerve carries the sensation to the brain, which determines the nature of a substance emitting the smell.

Touch:

There are encapsulated nerve endings in the skin, which respond to slight pressure on the skin. The skin responds to heat and cold also. Experiments have shown that the spot in the that respond to cold don’t respond to heat and vice versa. It is also known that any stimulus that affects the free and exposed nerve endings produce the sensation of pain. Some sensory receptors are placed deeper in the tissues and are not stimulated unless the tissues above are firmly compressed.

Taste:

It is generally believed that the entire tongue is the organ of taste, but it is not so. The tiny organs of taste are located on the surface of the tongue. These are called the taste buds. They are spherical in shape and microscopic in size. A taste bud consists of a group of cells that are supplied with nerve endings from the nerve that penetrates the inner part of the mouth cavity. There are four kinds of taste buds, each kind specified to seek a particular taste, i.e. sweet, salty, sour and bitter. Those for salty taste are situated along with those for bitter taste on the side of the tongue and for sweet taste at the tip of the tongue.

FRIENDSHIP—CARLYLE AND J .S. MILL
                                                                                                                                                              
                                          Thomas Carlyle, the eldest son of James Carlyle was born in Scotland on 4th December, 1795.Carlyle was brought up as a strict Calvinist and was educated at the village school. As a boy he learned reading from his mother, arithmetic from his father; he attended a private school in Ecclefechan and then, at the age of six, the nearby Hoddam parish school. He immediately became the pride of the schoolmaster, the young person on whom approving adults and jealous schoolmates place the burden of differentness. He received training in French and Latin but over the next few years taught himself Spanish, Italian, and German. Carlyle also took a keen interest in literature and read the work of Daniel Defoe, Henry Fielding, Henry Fielding, Tobias Smollet , Laurence Sterne and William Congreve.
                                        Carlyles father expected him to attend divinity school after completing his university studies. However, he rejected this idea and in 1814 became a mathematics teacher at Annan Academy at £70 per annum. In 1816 he obtained a teaching position where he taught Latin, French, arithmetic, bookkeeping, geometry, navigation and geography. He held his wife in great esteem. He later wrote: "She could do anything well to which she chose to give herself.... She had a keen clear incisive faculty of seeing through things, and hating all that was make-believe or pretentious. She had good sense that amounted to genius. She loved to learn and she cultivated all her faculties to the utmost of her power. She was always witty … in a word she was fascinating and everybody fell in love with her."
                                   Thomas Carlyles reputation as an expert on literature and philosophy resulted in him receiving commissions. He started work on his first book, Sartor Resartus. Thomas and Jane Carlyle moved to London. He developed a close friendship with John Stuart Mill and he had several articles published in his Westminster Review .It was Mill who suggested that Carlyle should write a book about the French Revolution. He agreed and started the book in September 1834. After completing the first volume he sent it to Mill for his comments. On the night of 6th March 1835, Mill arrived at Carlyles house with the news that the manuscript had been burnt by mistake at the home of Harriet Taylor. The following day he decided to rewrite volume one again. The three volume book was not finished until 12th January, 1837. 
                                    Carlyle met Charles Dickens for the first time in 1840. Carlyle described Dickens  as "a fine little fellow... a face of most extreme mobility, which he shuttles about - eyebrows, eyes, mouth and all - in a very singular manner while speaking... a quiet, shrewd-looking, little fellow, who seems to guess pretty well what he is and what others are." The two men became close friends. Dickens told one of his sons that Carlyle was the man "who had influenced him most" and his sister-in-law, that "there was no one for whom he had a higher reverence and admiration".
 
Charles Dickens  dedicated his book, Hard Times  to Carlyle. He also helped Dickens with his book, A Tale of Two Cities.
"He (Dickens) had always admired Carlyles History of the French Revolution, and asked him to recommend suitable books from which he could research the period; in reply Carlyle sent him a cartload of volumes from the London Library. Apparently Dickens read, or at least looked through, them all; it was his aim during the period of composition only to read books of the period itself."
Thomas Carlyle died at his home in 1881.
