Nervous system

Definition  The nervous system consists of brain coma spinal cord peripheral nerve. The nerves health to transmit the message grow the impulses from different part of the body to the brain and spinal cord. The nervous system in divided in following part------- Central nervous system Peripheral nervous system Autonomic nervous system Central nervous system It consists then and spinal cord. Peripheral nervous system It consists of fall nervous outside the brain or spinal cord. Autonomic nervous system It consists of sympathetic and parasympathetic. Neurone  The nervous consist of vast number of cell called neurone. Neurone is the structural and fundamental unit of the nervous system Play Store the neurone are supported by a special type of connective tissue is called neuroglia, each neurone have a cell body and its process. Cell body The nerve cell are vary considered size and shape but they are too small cell body from the grey matter of The nervous system an

                 The digestive system describe the alimentary canal . it's accessory organ and a variety  of digestive processes that prepare food eaten in the diet for absorption. the aliminentary canal begins at the mouth passes through the thorax  abdomen and pelvis end the anus .           Process of digestion There are five type of process in the Digestive------- 1. Ingestion-- This is the taking of food in to the alimentary tract it means drinking and eating . 2. Propulsion-- This mixes and move the contents (food) along the alimentary tract . 3. Digestion -- This consist of ----------- (I) Mechanical breakdown of food by      mastication ( chewing ). (ii) Chemical digestion of food in to small          molecules by enzymes present in                  secretion produced by g lands an                    accessory organ the d igestive system . 4. Absorption --  This is the process by which digestive food substanc      pass through the wall

                       Position of the heart       The  heart lies in the thoracic cavit y in the media - sternum (the space between the lungs ).It lies oblique, a little more to the left then the right and present a base above and apex below .The apex is about 9cm to the left of the midline at the level of the 5th intercostal space, the base extend to the level of the 2nd ribs .         *  Structure of heart   *        The heart is composed of three layer of tissue ----------- 1. Pericardium  2. Myocardium  3. Endocardium      1. Pericardium   The pericardium is the outer layer and is made of to sac . The outer sac ( the fibrous pericardium ) consist of fibrous tissue. The inner layer of  pericardium is cold serous pericardium . The outer layer of parietal pericardium. Tha inner layer of serious pericardium is cold visceral pericardium . The serous membrane consist of ephythelium cells .It secretion serous fluid in to the space bitween the visc

Human Skeleton Systems

                    * Defination  The  skeleton system consist of the bone of the skeleton there joints and the skeleton muscles that move the body.                         * Bone  * Bone are the type of tissue which support the body, providing body framework and help the body movement.         * Function of bone *        1. Providing body framework. 2.Giving attachment to muscle. 3.The allowing movement of the body as whole and of part of the body by forming joint that are moved by muscle . 4.Forming the boundaries of the cranial,thoracic and pelvic cavity,protecting the organ they contain. 5.Hemopoisis the production of blood cells in red bone marrow.                             *    Type of bone  *   Bone are the classifieds as long bone ,short bone,irregular bone flat and sesamoid bone .     1.Long bone - These consist of a shaft and two extremities as the name suggests ,these bone are longer then they are wide -    Femur,Tibia ,Fibula.  2.  Short bone-  Ca
