  HUMAN BRAIN   Brain is a organ of soft nervous tissue contained in the skull of vertebrates, functioning as the coordinating centre of the body. PARTS OF BRAIN Human brain is divided into three major parts on the basis of their functions and placement :-  1. Fore Brain  2. Mid Brain  3. Hind Brain  DIAGRAM OF HUMAN BRAIN 1. FORE BRAIN :-    It is the anterior part of the brain  It has three parts :-  Thalamus Limbic System Cerebrum THALAMUS :- it is located above the brain stem and between the cerebral and Mid-Brain. FUNCTION :- It carries sensory information from the body to cerebrum and the limbic system. HYPOTHALAMUS :- It lies under the thalamus. FUNCTION :- It connects the nervous system with the endocrine system via pituitary gland. LIMBIC SYSTEM :- It is arc shaped structure between thalamus and cerebrum. FUNCTION :- It controls responses like :- Hunger Fear Thirst Anger   Sexual responses etc. CEREBRUM :- It is divided into two halves called cerebral hemisphere. They communi

 CANCER  Cancer is also known as Tumor, and study of cancer is called oncology . Definition  Cancer means uncontrol and abnormal division of cells. They are very rapidly proliferate without any differentiation and apoptosis process. (Abnormal proliferative cell is called Neoplastic cell ) Or The uncontrolled growth of cell by its multiplication is known as Cancer. Types of cancer  There are two types of Tumor :- 1. Benign Tumor  2. Malignant Tumor Benign Tumor  Benign Tumor is also called mass of cell. It cannot spread from one location to other location. That means it is not show metastasis. This is a localised tumor. That means it is present only one location not spread to other location. Benign Tumor  This type of tumor can remove from the body because it is located only on surface of organ. Benign Tumor  Example of Benign Tumor :-  Lipoma Myloma  Malignant Tumor  Malignant Tumor is very dangerous tumor because it can spread or can transfer from one location to other location. Malig

  Atrial Fibrillation  Atrial Flutter Atrial Fibrillation   (Afib) Afib stands for atrial Fibrillation (AF) Atrial Fibrillation is a type of arrhythmia or abnormal heart beat and is a major cause of stroke.  Atrial Fibrillation is an irregularly irregular and often very rapid heart rhythm that begins in heart upper chambers (Atria). in which the upper chambers of the heart (atria) beat out of coordination with the lower chambers of the heart (ventricle). ATRIAL FIBRILLATION FINDINGS ON ECG Findings Irregularly irregular QRS Complex P wave absent / no visible P wave present Heart beat range (100bpm - 160bpm) Types of Atrial Fibrillation There are three main types of atrial fibrillation.... Paroxysmal atrial Fibrillation Persistent atrial fibrillation Long standing persistent atrial fibrillation Paroxysmal Atrial Fibrillation It's episodes occurs less than one week and usually stops on its own without treatment. Persistent Atrial Fibrillation It's episodes occurs more than one we

  VITAMINS   Vitamin was invented by Sir F.G Hopkins. The term vitamin was coined by Funk. Vitamins are organic compound required in minute quantities. No Calorie is obtained from it, but it is very important in regulating chemical reactions in metabolism of the body. On the basis of solubility, vitamins are of two types :- Fat Soluble Vitamins :-  K, E, D, A Water Soluble Vitamins :-  B and C Vitamins and their Chemical name  Vitamins                  Chemical name         A.                                Retinol        B1.                               Thiamine       B2.                              Riboflavin        B3.                         Nicotinamide/Niacin          B5.                         Pantothenic acid       B6.                               Pyridoxine        B7.                               Biotin       B11.                              Folic acid        B12.                       Cynocobalamine        B9.                                 Folic acid         C.
