What's a funny bone??

FUNNY BONE!!!

Have you ever hit the inside of your elbow in just the right spot and felt a tingling or prickly kind of dull pain? That's your funny bone! It doesn't really hurt as much as it feels weird. The "funny bone" got its nickname because of that funny feeling you get after you hit it.

But your funny bone isn't actually a bone at all. Running down the inside part of your elbow is a nerve called the ulnar nerve. The ulnar nerve lets your brain know about feelings in your fourth and fifth fingers. It's also one of the nerves that controls some movement of your hand.

You get that funny feeling when the ulnar nerve is bumped against the humerus (say:  HYOO-muh-rus), the long bone that starts at your elbow and goes up to your shoulder. Tapping your funny bone doesn't do any damage to your elbow, arm, or ulnar nerve. But it sure feels strange!

The 3 Body Types !

The 3 Body Types :Ectomorph, Mesomorph, and Endomorph

The Ectomorph Body Type

The ectomorph can be easily spotted in any weight room. They are often below the average weight for their height and have a skinny appearance. Ectomorphs tend to have very high metabolisms and often complain of relentless eating with little to no weight gain.

Common Ectomorph Characteristics  Include:

• Small joints
• Skinny appearance
• Hyperactive
• Fast metabolism
• Can eat whatever they want
• Get full easily
• Small chest and buttocks
• Difficulty building muscle
• Difficulty gaining weight
• Low body fat
• Narrow frame (“pencil frame”)

The Endomorph Body Type

The endomorphic body type is the complete opposite of an ectomorph. This individual will usually be larger in appearance with heavier fat accumulation and little muscle definition. They find it hard to drop the weight even though they try several diets or workout programs.

Common Endomorph Characteristics  Include:

• Large amount of fat accumulation
• Often fatigue easily
• Insatiable appetite
• Try various diet and exercise programs to failure
• Cannot seem to drop weight
• Eat larger meals or several smaller sized meals
• Low muscle definition due to adipose tissue
• Larger frame

The Mesomorph Body Type

Everyone recognizes the mesomorph. He is the high school jock that seemed to put on muscle just by looking at weights while also maintaining a very lean physique. The mesomorph is somewhat in between the ectomorph and the endomorph and as such, display qualities from both. He has a larger frame (bone structure) as the endomorph does, but a low body fat percentage as the ectomorph has. You could say this is the aspiring body type that everybody wants.

Common Mesomorph Characteristics  Include:

• Symmetrical build
• Wide shoulders
• Small waist
• Low body fat
• Large musculature
• Seems to put on muscle easily
• Seems to burn fat easily
• Eats in moderation

Indian cobra

Indian cobra

Indian cobra (Naja naja) also known as the Spectacled cobra, Asian cobra or Binocellate cobra is a species of the genus Naja found in the Indian subcontinent and a member of the "big four", the four species which inflict the most snakebites on humans in India. This snake is revered in Indian mythology and culture, and is often seen with snake charmers. It is now protected in India under the Indian Wildlife Protection Act (1972).

Bioluminescence

Bioluminescence

Bioluminescence is the ability of an organism to create light through chemical reactions. Creatures use bioluminescence in many ways: to light their way, attract prey, or seduce a mate. Many underwater animals are bioluminescent—from the viper fish to the flashlight fish, which is named for its light.Some creatures, such as the angler fish, have a concentration of photophores in a small limb that protrudes from their bodies, which they use as a lure to catch curious fish. Bioluminescence can also confuse enemies. The chemical process of bioluminescence requires at least two chemicals: the light producing chemical called luciferin and the reaction causing chemical called luciferase. The luciferase catalyzes the oxidation of the luciferin causing light and resulting in an inactive oxyluciferin. Fresh luciferin must be brought in through the diet or through internal synthesis.

Deep sea creature

The term deep sea creature refers to organisms that live below the photic zone of the ocean. These creatures must survive in extremely harsh conditions, such as hundreds of bars of pressure, small amounts of oxygen, very little food, no sunlight, and constant, extreme cold. Most creatures have to depend on food floating down from above.

These creatures live in very harsh environments, such as the abyssal or hadal zones, which, being thousands of meters below the surface, are almost completely devoid of light. The water is between 3 and 10 degrees Celsius and has low oxygen levels. Due to the depth, the pressure is between 20 and 1,000 bars. Creatures that live hundreds or even thousands of meters deep in the ocean have adapted to the high pressure, lack of light, and other factors.

Why did kings become so powerful in Europe?

Why did kings become so powerful in Europe?

Before the 1500s, nobles were always plotting revolts aganist kings. Over time, kings raised the money to pay for full-time armies, putting an end to civil wars. Kings started to believe they had a divine right to rule and that no one could tell them what to do.
