Ggg
:
Heart
Nerve supply of heart
control rate and strength of contraction
2 Deep plexuses
formation
cardiac branch of 2 sympathetic chains
2vagal except 2 branches of superficial plexus
branches
1 cardiac branches of right and left atria
2 right and left coronary plexuses
3 right and left anterior pulmonary plexuses
front of tracheal deep to aortic arch
1
Superficial plexuses
in concavity of aortic arch
branches
1 Deep cardiac plexues
2 Right coronary plexus
3 Left anterior pulmonary plexues
formation
superior cervical branch of left sympathetic chain
inferior cervical branch of left vagal parasympathetic chain
Arterial supply of the heart
Left coronary artery
2 anterior interventricular artery > anterior surface of both ventricles and anterior 2\3 anterior interventricular septum
left conus artery > root of pulmonary trunk and ascending aorta
1 circumflex coronary artery
1 marginal > left ventricle
2 branches to left atrium and ventricle
in posterior part of A\V groove
from left posterior sinus ,between pulmonary trunk and left atrium
Right coronary artery
1 marginal artery > right ventricle
3 right conus branch > root of pulmonary trunk and ascending aorta
from anterior aortic sinus , between pulmonary trunk and right auricle to reach anterior atrioventricular groove
4 small branches > right atrium and S-A node , right ventricle its anterior and diaphragmatic surface
2 posterior interventricular artery > both ventricle and nodal part in 80% of people
Venous drainage of heart
1 coronary sinus
1 Great cardiac vein : anterior interventricular groove
2 Middle cardiac vein : posterior interventricular groove
3 small cardiac vein
in posterior A\V groove , has semilunar valves
4 oblique vein of left atrium
