Nervous System in Human Beings

Nervious System In Human Beings

 Central Nervous system includes the brain and spinal cord. The brain and spinal cord are protected by bony structure, membranes and fluids. The brain is held in cranial cavity or Skull.

Funtion of Nervous system:-The function of nerous system is to gather information from different parts of body to the brain, where the brain analysis this data and sends message to that particular region/part of the body to take action. Here comes both an internal and external environment of body.

Working.. The messages are taken from the site to the brain through neurons and the message from the brain to the site is also carried by neurons. The neurons which take information from the site ti the brain are known as Sensory nervous and the neurons which take information from brain back to the site are know as Motor nervous.

  MODES OF REPRODUCTION USED BY SINGLE ORGANISMS                                                            Part 1 The modes by which various organisms reproduce depend on the body design of the organisms. Unicellular organisms reproduce by means of following processes:- Fission:-   Fission is the process of spliting of unicelluar organisms or single celled organisms into the two are more than two cells, each cell forms the new individual. The new individual formed is exact copy of parent cell. Fission is of two types:-            A) Binary Fission:-  when the single parent cell divides into two new daughter cells, each new                                                ...

Digestion in Human Beings for class 10th

Digestion As the Human Beings show Holozoic mode of nutrition , theres is a system in Human Beings which Digests this food into the simple molecules called Gollucose. Digestion:- The process in which an organism breaks complex food molecules into simpler once for respiration is called digestion. Q.1 what is need to Digest food?  As the food is in complex form , body cells cannot use it directly so there is a need to change its form from complex to simple one. Digestion in Human Beings Digestion In Human Beings starts from mouth.The cavity inside the mouth is called as Buccal cavity.Buccal cavity contains Teeth and Tongue.In mouth food is broken into small pieces with the help of Teeth and is mixed with saliva secreated by Salivary gland. Saliva contains digestive enzymes called as Salivary Amilase (Ptylin).These enzymes digest food to some extend.Tongue in a mouth helps in mixing food with saliva and is also percieves the taste of the food. The food than enters i...

Modes of Nutrition for 10th class

Modes of Nutrition in Organism 1. Autotrophic mode of nutrition:- In this mode of nutrition, organisms synthesize their own food by using simple raw materials from their environment . Examples are Plants , some bacteria, algae and euglina. It has following sub types  Photo-autotrophic Nutrition:- In this mode of autotrophic  nutrition organisms synthesize their own food by using simple raw material from their environment e.g carbon dioxide,water and sunlight. examples are Plants , Algae etc. These organisms have special units in their cell to trap sunlight called as Chloroplast which are green in color. chemo-autotrophic nutrition:- In this mode of nutrition organisms synthesize their food from some chemicals. e.g some bacteria ( sulfur-oxidizing  bacteria , nitrogen-fixing  bacteria ) KEEP LEARNING , KEEP SHINING see the next post for further
