There are many causes of Unconsciousness the most common of which are head injury, fainting, heart attack, stroke, asphyxia, epilepsy, shock, poisoning, infantile convulsions and diabetes etc. There are many causes of Unconsciousness and it can occur as a result of head injury, giving rise to concussion or compression. Disturbance of the blood supply to the brain as in fainting, heart attack, shock and stroke are some symptoms. Disturbance of the electrical activity of the brain giving rise to fits.

Central nervous system comprises of the brain, spinal cord and the nerves. The nervous system is of two types. Sympathetic nervous system and parasympathetic nervous system. The brain which weighs 1430 grams is an extremely delicate structure made up of a mass of nerve cells. It is here that sensations are analyzed and orders are given to the muscles. The brain is divided into three regions namely cerebrum, cerebellum, and medulla oblongata. Each region has its own specific function. The brain is covered by a thin sheet called meningitis. It provides lubrication to the brain. The brain is encased in the skull and suspended in clear fluid, which acts as a partial shock absorber. Nonetheless, since it is free to move within the skull. The brain is sensitive to violent movement of pressure. The spinal cord is a mass of nerve fibers extending from the brain through the opening in the base of the skull. The cord runs through the spinal column. The peripheral nerves emerge in pairs, each containing motor and sensory nerves, from the brain and the spinal cord. Sensory nerves transmit impressions received by the senses to the brain and motor nerves then transmit the ‘orders’ given by the brain to the voluntary muscles. When a nerve is cut there is a loss of feeling, power and movement in that part of the body controlled by a damaged nerve. The automatic nervous system is a network of nerves which controls the involuntary muscles – the muscles which regulate the vital functions of the body such as circulation, respiration, and digestion. This system is not controlled by the will and acts continuously whether a person is awake or asleep.

The skeleton forms the supporting framework of the body and consists of separate bones joined together by means of cartilage, Ligaments and muscles. The parts of the skeleton are the skull, the back bone or the spine, the ribs and the breast bone, the upper limbs, the pelvis and the lower limbs. The skull is the skeleton of the head and is made up of the dome, frontal, parietals, temporal and occipital. The skull contains the brain and has bony provision for formation of eyes, ears and nose. It is round in shape and has an opening at the bottom through which the spinal cord enters the vertebral column. The back bone or the spine consists of thirty three small rounded pieces of bones each called a vertebrae placed one above the other. There are twelve pairs of the ribs which are attached to the corresponding vertebrae at the back. The first seven pairs are attached to the breast bone in the front, eight, ninth and tenth pair of rib i.e. eleventh and the twelfth have no attachment in the front and are known as ‘floating ribs’. The ribs and the breast bone are liable to be fractured in accidents due to either direct of indirect causes. The two bones one on the either side is joined together form the pelvis. The pelvis forms a basin shaped cavity which contains intestines, urinary bladder and reproductive organs. Joints are junction of two or more bones in the body.

Bicycles are used for the purpose of transport from one place to another. It is being used from past centuries. Bicycles are usually made of light metals. The set up has two wheels which is made of steel spokes and a rubber tube is fixed over the casting. The two wheels are connected by means of a steel chain.
