HUMAN MUSCLES -There are about 600 muscles in a human body. • Classification of muscles based on different factors : (1) Depending upon striation. (2) Depending upon the control. (3) Depending upon the situation. 1) Depending upon striation : – Depending upon presence or absence of striation muscles are classified as, (a) Striation muscle (b) …
SKELETAL MUSCLE •Muscle mass : – Skeletal Muscle mass is made up of large number of individual muscle cells or myocytes. -Myocytes are long and slender in appearance and are commonly called muscle fibers. -Muscle fibers are arranged parallel to one another with some connective tissue in between and they are multinucleated. – Fascia separates …
ARTERIAL BLOOD PRESSURE INTRODUCTION –Arterial blood pressure is a lateral pressure exerted by blood on the wall of the arteries. -Blood pressure is measured indirectly by using sphygmomanometer. • Types of blood pressure ; 1) Systolic blood pressure 2) Diastolic blood pressure 3) Pulse pressure 4) Mean arterial blood pressure. – Normally blood pressure …
ANATOMY OF HEART INTRODUCTION -The heart is a muscular pump which is responsible for blood circulation. -It is a conical hollow muscular organ situated between the lungs in the middle mediastinum. -It is enclosed within the pericardium. -It pumps blood to the various parts of the body to meet their nutritive requirements. -Heart is …
INTRODUCTION -ECG refers to graphical recording of electrical activities of heart-electrocardiogram. -The electrical activity occurs prior to mechanical component of cardiac cycle. -Electrocardiography is the technique and electrocardiograph is the instrument used to record electrical activities. • Uses of ECG : 1) To record heart rate ( when heart rate is very high) 2) …
INTRODUCTION Cardiac murmur is the abnormal heart sound. It is also called cardiac bruit. Cardiac murmur is mainly heard by stethoscope, along with the normal heart sounds. CAUSES OF MURMUR -It is produced because of change in the pattern of blood flow. -Normally, the blood flows in streamline through the heart and blood vessels. …
INTRODUCTION -Heart sound are the sounds produced by the mechanical activities of heart during each cardiac cycle -Heart sounds are produced by-: 1)FLOW OF BLOOD THROUGH CARDIAC CYCLE 2)CONTRACTION OF CARDIAC CHAMBER 3)CLOSURE OF BALVES OF THE HEART Heart sounds can be heard by placing the ear over the region of chest or by …
Definition – Amount of blood pumped to the body from each of the ventricles are called as cardiac output. -Normal cardiac output of the heart is 5 liters per minute Stoke volume and HEART RATE are the 2 main components that controls the cardiac output CARDIAC OUTPUT= …
-Heart consist of specialized cardiac muscle which produced heart to beat and supply blood to all parts of the body -The conducting system of heart include the following:- 1)SA NODE 2)INTERNODAL PATHWAY 3)AV NODE 4) BUNDLE OF HIS 5) BUNDLE BRANCHES 6)PURKINJE FIBRE Explanation of each of the following system 1) SA NODE -It is …
CARDIAC CYCLE It is the Succession of coordinating events taking place in heart during each beat. The cardiac cycle takes 0.8 sec to complete a pump. Each heart beat consist of 2 major periods. 1)SYSTOLE 2) DIASTOLE In systole heart pumps the blood to the arteries to all part of the body In diastole …
