Structure and function of human brain

Structure of Human Brain

Human brain is well protected in a cranium cavity, in a skull. The Human brain has 3 membranes called Meninges. The space between the 3 membranes is filled with the fluid called Cerebro-spinal fluid which protects the brain from mechanical shocks.

Brain is divided into three regions
1. Fore Brain:- It is further divided into 3 parts
• Cerebrum:- It is the main thinking part of the brain. It is the center of intelligence, Memory, consciousness, willing power and voluntary actions.
• Thalamus:- It relays pain and pressure impulses to the cerebrum.
• Hypothalamus:- It controls body temperature and secretion of Pituitary gland.

2. Mid Brain:- It doesn't have any further divisions. It controls reflex movements.

3. Hind Brain:- It has 3 regions

• Cerebellum:-It balances body.

• Pons Verolii:-It connects cerebrum with cerebrum, and transfer messages in between them.

• Medulla:-It controls involuntary activities of body e.g breathing, heart beating etc. Any injury in this part can lead to the death.

Absorption of Nutrients in Small Intestines

The digested food is now in simple form and is ready to use by cells. The inner wall of small intestines is called as Mucosa, it has numerous finger like projections called as Villi (singular- villus), which in-turn has finger like projections called as micro-villi. The purpose of villus is to provide large surface area for nutrient absorption. Villi have large network of blood capillaries, where the nutrients are absorbed in blood by diffusion.Most of the nutrients are absorbed in jejunum. except Iron is absorbed in duodenum vitamin B12 and bile salts are absorbed in the terminal ileum. Through blood digested food reaches to each and every cell of the body.

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

Photosynthesis for class 10th

● Photosynthesis ( Photo=Light) :-The biological process In which the plants synthesis their own food with the help of SunLight, Carbon Dioxide and water.It is the characteristic feature of plants. Photosynthesis takes place in the leaves of plants.where the sunlight is traped by green pigment chloroplast.Carbon Dioxide is taken from Atmosphere through Minute pore On leaves called stomata and water is absorbed by roots from soil and conducted to leaves through xylum to leaves. Oxygen is released after Respiration through stomata. Examine the below Diagram
