-Important facts about teeth-


Teeth contribute to the important functions of food mastication, swallowing, digestion, speech, and aesthetics in humans. Each tooth component serves a specific purpose.

The development of human teeth begins in the womb. Children generally have their primary tooth (deciduous tooth) eruption around 6 months of age. By the age of 12, most primary teeth have been lost and secondary teeth continue to replace those teeth until adulthood.

The human tooth is divided into three different parts:

  • Crown – This is the visible portion of the tooth. It covers nearly two-thirds of the total tooth structure. The crown lies above the gums (gingiva).
  • Neck- The small and narrow portion lying between the crown and root of the tooth.
  • Root – It consists of one-third of the tooth and is deeply seated inside the bone supporting the tooth. This part of the tooth lies below the gums and is usually not visible in healthy teeth.

-African Culture and It’s Values-

Image
African culture is embedded in strong moral considerations. It has a system of various beliefs and customs which every individual ought to keep in order to live long and to avoid bringing curses on them and others. Adultery, stealing and other forms of immoral behavior are strongly discouraged and whenever a suspected offender denies a charge brought against him, he would be taken to a soothsayer or made to take an oath for proof of innocence. In Ibibio land for instance,  ukang   (ordeal) is very popular as a method of crime detection. The soothsayer who specializes in it sets a pot of boiling oil, drops a stone into it and asks the suspects to attempt to retrieve the stone. The guiltless can reach to the bottom of the pot and retrieve the stone without the hair on his arms getting burnt. But when the culprit approaches the pot, it rages and boils over in a manner that even the most daring criminal would hesitate to make an attempt at retrieving the stone. The fear of being m...

-Solar Deity (Sun Worship)-

Image
sun worship, veneration of the sun or a representation of the sun as a deity, as in Atonism in Egypt in the 14th century  BCE . Although sun worship  has been used frequently as a term for “pagan” religion , it is, in fact, relatively rare. Though almost every  culture  uses solar motifs, only a relatively few  cultures  (Egyptian, Indo-European, and Meso-American) developed solar religions. All of these groups had in common a well-developed urban civilization with a strong ideology of  sacred kings-ship . In all of them the imagery of the sun as the ruler of both the upper and the lower worlds that he majestically visits on his daily round is prominent. The sun is the bestower of light and life to the totality of the cosmos; with his unblinking, all-seeing eye, he is the stern guarantor of justice; with the almost universal connection of light with enlightenment or illumination, the sun is the source of wisdom. These qualities sove...

-Dreams-

  We all have dreams,  whether you remember them or not . Dreams can be pleasant, happy, frightening, frustrating, calming, boring, bizarre or downright awkward. (Anyone else ever dream about standing naked in front of a crowd?) Each night, you can have anywhere from one dream up to five or six, depending on how long you sleep and how many rapid eye movement cycles you go through, but you may only remember the most vivid or repeatedly occurring dreams. If you've ever woken from a particularly unsettling or outlandish dream, you may wonder why you dream the things you dream.Unfortunately, but not surprisingly scientists can't attach particular meanings to every dream. It's up to the dreamer to determine what their sleepy, subconscious mini-movies mean, you can start dissecting yours with the help of three sleep experts in this guide to dreams.    To put it simply, "Actually Dreams are thoughts, images, sensations and sometimes sounds that occur during sleep,...
