Dosage Forms: - Dosage forms are the carrier through which drug molecules are delivered to sites of action within the body. - Every dosage forms is a combination of the drug and different kinds of non–drug components called as Excipients or additives. - The additives are used to give a particular shape to the formulation, to increase stability, palatability & more elegance to preparations. TYPES OF DOSAGE FORM 1.  Solid dosage  forms             2. Liquid dosage  forms 3. Semi-solid dosage forms 1 .  Solid dosage  forms   Tablets: 1. These are solid unit dosage forms of medicaments intended for oral administration which are prepared by molding or by compression with or without excipient 2. The tablets can be prepared by two methods namely as a I) Dry granulation, II) Wet Granulation Capsule: 1. Capsules are solid unit dosage forms in which one or more medicam...

Tissues • Tissues are composed of cells similar in structure and specialized to perform a specific function for the body. • The human body is made of four general types of tissues . – Epithelial tissues – for lining body cavities, covering internal organs and large surfaces. –  Connective tissues – for supporting and linking tissues or organs together; some are specialized to provide protection, to store fat, and even to provide circulatory function in the cardiovascular system. – Muscle tissues – for providing contraction and relaxation in the body surfaces, in the heart chambers , and in hollow organs such as blood vessels and the digestive tract. – Nerve tissue – for generating and transmitting electrical signals (nerve impulses ) in the brain, spinal cord, and nerves.

Cell division It is two type - 1. Mitosis 2. Meiosis 1. Mitosis - In this division indentical cell is formed form parent cell  2. Meiosis - in this division first parent cell decided in two indentcal cell divide in two different cell.  by this division four different cell produce - 1. Prophase 2. Metaphase 3. Anaphase 4. Telophase 

Skeletal System        The  Skeletal System -  It gives shape of the body .                      - It provides support to the body. - It provide movement of the body. -  muscles helps a person  move - Produces blood cells - Stores calcium            SECTIONS OF THE SKELETAL SYSTEM • Axial skeleton • Appendicular skeleton AXIAL SKELETON-  Skull   • The skull consists of the  cranium and facial bones . • Cranium      ▫ 1 frontal ▫ 2 parietal ▫ 2 temporal ▫ 1 occipital ▫ 1 ethmoid ▫ 1 sphenoid • Sutures. • Facial bones  ▫ 5 nasal ▫ 2 maxilla ▫ 2 lacrimal ▫ 2 zygomatic ▫ 2 palatine ▫ 1 mandible • 26 Vertebrae • 7 cervical • 12 thoracic • 5 lumbar • 1 sacrum • 1 coccyx Thorax • 12 pair Ribs • 7 true • 5 false • Sternum ▫ Manubrium ▫ Gladiolus...

 Nutrition in plants Green plants are autotrophic and synthesize their own food by the process of photosynthesis. The process, by which green plants make their own food from carbon dioxide and water by using sunlight energy in the presence of chlorophyll, is called photosynthesis. Oxygen is released during photosynthesis. The process of photosynthesis can be represented as : The process of photosynthesis takes place in the green leaves of a plant. The food is prepared by the green leaves of a plant in the form of simple sugar called glucose. The extra glucose is changed into another food called starch. This starch is stored in the leaves of the plant. The green plants convert sunlight energy into chemical energy by making carbohydrates. The photosynthesis takes place in the following three steps: Absorption of sunlight energy by chlorophyll. Conversion of light energy into chemical energy, and splitting of water into hydrogen and oxygen by light ene...

           TRANSPORT ACROSS CELL MEMBRANE  TWO TYPES SS CELL OF TRANSPORT ACROSS CELL  MEMBRANE- 1. ACTIVE TRANSPORT 2. PASSIVE TRANSPORT 1. ACTIVE TRANSPORT -  Substances that are too large or polar diffuse across the lipid bilayer on their own through membrane proteins called carriers, permeases, channels, and transporters. Unlike active transport, this process does not involve chemical energy. So the passive mediated transport is totally dependent upon the permeability nature of cell membrane, which in turn, is a function of organization and characteristics of membrane lipids and proteins.   Types of Active transport:   1. Diffusion : Diffusion is the movement of particles from an area of high concentration to an area of low concentration.                                             ...
