General intraembryonic coelom development

heart is surrounded by splanchnic mesoderm-lined cavity

lateral fold closes ventrally

Cavity is continuous with all regions as intraembryonic coelom

Formation of pleural cavity

Septum transversa is transverse btw sinus venosus and liver(gut)

Pleural cavity expands with lungs

Formation of pericardium

cardinal veins form and mesenchymal tissue forms the pleuropericardial fold which around heart

Layer encountered during Blalock Taussig Thomas

4th intercostal space

Skin- superficial fascia-cutaneous trunci- external abdominal oblique (ventral) and latissimus dorsi (dorsal)- external intercostal muscle- internal intercostal muscle- endothoracic fascia- costo-parietal pleura visceral pleura- mediastinum parietal pleura- mediastinum visceral pleura- fibrous pericardium- parietal pericardium- epicardium

Vertebral artery anastomoses for thoracic collateral circulation

7 ventral cervical branches anastomose with other side to form ventral spinal artery

Vertebral artery divides in vertebral canal cranially and caudally which anastomose with opposite side (cranial forms basilar artery)

Basilar artery divides and each branch anastomoses with caudal communicating arteries from internal carotid

Cephalic vein to the heart

1. cephalic-external jugular-brachiocephalic-cranial vena cava

2. cephalic- axillobranchial- left subclavian-brachial cephalic v- cranial vena cava

3. cephalic- axillobranchial- omobrachial-external jugular- brachial cephalic-cranial vena cava
