In this channel I creat lectures for medical students. Lectures contain the basic concepts of medical topics. All the lectures are very useful for medical students and also covers the MCQs asked in various competative exams.
6:40 2 main branch 1) circumflex a 8:52 First runs along w the anterior ant.left part of atr.ven. groove. THEN winds back to the post as post.atr.ven.groove to meet crux & anastomosis w the right.coro.art 9:20 circmfl er brach LEFT MARGINAL ART 9.30 circmflx also branch to SOME ANT.LEFT.ARRIAL-VENTRICULAR SMALL ART 2) ant interventricular a/ LEFT ANT. DESCENDING ART/LAD ART... Then goes down to the Post. Int.ven groove and anastomosis w Post.int.ven art 7:36 numeorus Ant. ventricular small branches to SUPPLE left ventricle surface 7:55 DIAGONAL ART comes out of ant.int.v.art (below the circmflx)
BRANCHES: 3:18 a) right Conus artery SUPPLIES the anterior part of the conus arteriosus/infundibulum. (Sometimes it appears as a main 3rd branch of R.Coro.A ,not as brach.) B) 3:55 R8 anterior Atrioventricular groove/right coronary sulcus er artery tar SOTO BRANCHES ber hoy = Atrial Branches SUPPLIES the mayocardium of r8 atrium C) SA NODAL ARTRY: in 60% case SA node is supplied by ONE OF THE anterior atrial brnaches of teh r8 cor.artery D) 4:30 2-3 anterior VENTRICULAR BRANCHES supplies ant surface of r8 ventriclcle E) 4:47 one of the ANT.VENT branch runs down to the apex of the heart along w the inferior border(largest r.branch) = Right Marginal Artry F) Post vent branches 5:05 in the post part of the right atrio-ventclr groove .SUPPLIES diaphragmatic surface G) 5:30 near the crux, POST. INTERVENTRICULAR Art brancch (90% case= right dominance,valo, branch of r.coro.art to the post.int.ven. groove)
00:25 tehy anastomosis w each other (not end artery) but actually functions as end artery 2:33 1st run forwards between pul trunk and righr auricle 2:47 then it goes down/descents almost vertically at=Anterior atrial-ventricular groove UPTO THE JUNCTION of right border & inferioyborder 3:00 then it runs posteriorly at the right post RIGHT PART of atrioventricular groove & reaches the crux of heart= anastomosis w CIRCUMPLEX branch of the left coronary artery BRANCHES: 3:18 a) right Conus artery SUPPLIES the anterior part of the conus arteriosus/infundibulum. (Sometimes it appears as a main 3rd branch of R.Coro.A ,not as brach.) B) 3:55 R8 anterior Atrioventricular groove/right coronary sulcus er artery tar SOTO BRANCHES ber hoy = Atrial Branches SUPPLIES the mayocardium of r8 atrium
