Goal/Aim (Main Objective) Define pericardium & different reflections of pericardium. Describe the gross structure of the heart and Enlist the Coronary arteries, its branches and major blood vessels Identify chambers of the heart . Identify internal structures of various chambers of the heart. Describe the different components of conduction system of the heart and sympathetic and parasympathetic innervation.
Specific Learning Objectives (cognitive) At the end of the lecture the student will able to : Define pericardium & different reflections of pericardium.

Identify internal structures of various chambers of the heart. Describe the different components of conduction system of the heart and sympathetic and parasympathetic innervation.
Psychomotor Objective : ( Guided response) A student to draw labelled diagram of Heart and its innervation
Affective domain To be able to display a good code of conduct and moral values in the class. To cooperate with the teacher and in groups with the colleagues. To demonstrate a responsible behavior in the class and be punctual, regular, attentive and on time in the class. To be able to perform well in the class under the guidance and supervision of the teacher. Study the topic before entering the class. Discuss among colleagues the topic under discussion in SGDs. Participate in group activities and museum classes and follow the rules. Volunteer to participate in psychomotor activities. Listen to the teacher's instructions carefully and follow the guidelines. Ask questions in the class by raising hand and avoid creating a disturbance. To be able to submit all assignments on time and get your sketch logbooks checked.

HEART (surfaces) Sternocostal (anterior) Diaphragmatic (inferior) Base (posterior) Apex
Pericardial Sinuses No clinical Significance Forms during development the way heart bends On posterior surface of heart Recess & reflection of serous pericardium around large vessels
Borders of the Heart Right : (right atrium) Left : (left auricle, left ventricle) Lower : right ventricle ,right atrium) Apex (left ventricle)
Structure of the Heart Myocardium , Epicardium (Outside) , Endocardium (Inside) Interatrial septum Interventricular septum Fibrous skeleton
Chambers of the Heart Right & left atria Right & left ventricles
R IGHT ATRIUM Outside Sulcus terminalis Rudimentary, Non Functional

Arterial Supply of the Heart
Right coronary artery R ight conus artery A nterior ventricular branches M arginal branch P osterior ventricular branches P osterior interventricular (descending) artery A trial branches A rtery of the sinuatrial node
left coronary artery A nterior interventricular (descending) branch ventricular branches (left diagonal artery ) left conus artery C ircumflex artery L eft marginal artery Anterior ventricular Posterior ventricular branches Atrial branch
Venous Drainage of the Heart G reat cardiac vein S mall and middle cardiac veins A nterior cardiac vein
Nerve Supply of the Heart Sympathetic P arasympathetic
Sympathetic innervation: increases heart rate & contractility via fibers from sympathetic trunk . Parasympathetic innervation: decreases heart rate via vagus nerve, which influences SA & AV nodes.
