Teeth and Bones

Teeth

-In lower vertibrates, the teeth are replaced continuously. This condition is called Polyphyodonty.

- Diphyodont is a condition in which there are only 2 definite sets of teeth.

Teeth Types

Incisiors are used for cutting and biting. Canines are used for stabbing. Premolars are used for cutting and Molars  are used for grinding.

Dental Formula:  Dental formula for Milk set for man is 2120/2120= total 20 teeth. For an adult man the dental formula is 2123/2123= Total 32 teeth.

Dental Trivia

1. First Milk Teeth to appear are Incisors while the first permanent teeth to appear is 1st Molar.

2. First Molar is the largest of all teeth while the third molar (last) which is also called the wisdom toot is the smallest.

3. Tusks of Elephats are modified incisor teeth.

4. African Elephants, both males and females have tusks while in India only males have them.

5. The prolonged teeth of Wild Boars are modified Canine Teeth.

Human Bones

The bone of brain box is called Cranium, Cheek bone is called Zygomatic bone, Upper jaw bone is called Maxilla, that of lower jaw is called Mandible. Collar bone is called Clavicle, Shoulder bone is called Scapulla, Hip Bones are named as Ilium, Ischium and Pubic. Knee bone is called Patella, chest bones are called Pectoral Glands, waist bones are called pelvic girdles. Upper arm bone is called Humerus, fore-arm bone are called Radius and Ulna. Wrist bones are called Carpals and Palm Meta Carpals. Finger bones are called Phalanges, thigh bone is called Femur, shank bones are called Tibia and Febula. Ankles are called Tarsals, sole bones are called meta tarsals, Foot-fingers are called phallanges and Sessamoid.

Bones Trivia

1. At the time of birth, the total of bones are 350 while in adults it is 206.

2. Each bone meets with other except Hyoid bone ( U-shaped) at the neck. It is helpful in crime identification.

Notes on General Chemistry-1

CHEMISTRY

SCOPE OF CHEMISTRY:

Deals with matter and the changes that matter undergoes when subjected to the action of heat light, electricity and other matter.
Elements: Substance which cannot be subdivided by any physical or chemical method.
Metals: Silver, Gold, copper sodium etc
Non metals: Oxygen, hydrogen sulphur etc.
Mixtures and compounds :
Iron + Sulphur = Mixture – Possesses both properties of iron and sulphur.
Iron + Sulphur-------------- Heated----FeS--- Compound- Properties of Iron and sulphur are lost.

Kinetic Theory of Matter: It says the pressure of a gas as due to bombardment of the wall of the vessel by the molecules of the gas.

Chemical Reactions:
Decomposition: (AB-------------- A+B)
Combination: (A + B--------------AB)
Double decomposition: (AB + CD----------- AD+ BC)
Displacement: (A +BC---------------- AC + B )

If the heat is evolved in a reaction it is called exothermic if heat is absorbed it is endothermic reaction.

ATOMIC STRUCTURE:
First given by John Dalton : says atom is indestructible.

Nucleas: Rutherford. The entire mass is concentrated in the nucleus which contain protons and neutrons, their total number equal to atomic mass.

The atomic number which is net positive charge on nucleus is equal to the number of protons.
Since the atom is electrically neutral , a number of electrons is equal to the number of the protons revolve around the nucleus.

Chemical Bonding: The force of attraction which binds the atoms in a molecule is called Chemical bonding.

Isotopes: They are atoms of the same element having the same atomic number but different atomic masses. They differ in the number of neutrons in the nucleus.

Nuclear fission: When certain heavy atoms like Uranium are bombarded with high velocity neutrons, new fast moving neutrons are released along with a large amount of energy. This process is called neuclear fission.

If all the neutrons are used in producing more fission a rapid and violent reaction takes place. This is the basis of the atomic bomb.

Nuclear Fusion: The two isotopes of hydrogen eg. Deutruim and Tririum react to produce, helium, neutron and a flood of energy. This is called fusion, and forms the basis of H-bomb.

Oxidation and Reduction:
Occur side by side.
Wherever there is oxidation, there is reduction.
When Chlorine oxidized Hydrogen sulphide to Sulphur, Hydrogen Sulphide reduces Chlorine to Hydrogen Chloride. Cl2 + H2S--------------- 2HCl + S

Oxidation: Removal of hydrogen or addition of oxygen or removal of electrons.
Reduction: Addition of hydrogen or removal or oxygen or addition of electrons.

Mathces: Side of the Box: Red phosphorous or phosphorous trisulphide.
Match Sticks: Impregnated with borax- so that they can be extinguished without glowing for a long time.

Heavy Water:
Discovered by Urey.
Contains heavy hydrogen atom i.e deuterium(D)
Formula D2O
Density 1.106

Used in Nuclear reactors to absorb neutrons
