Superficial temporal artery is the smaller of the two terminal branches of the external carotid artery. At first, Superficial temporal artery passes under cover of the parotid salivary gland, behind the temporomandibular articulation emerges from the deep face of the parotid salivary gland at its anterior part in company with the satellite vein and auriculo-palpebral […]

External Maxillary artery arises from the common carotid artery, passes downwards and forwards on the lateral wall of the pharynx in company with the hypoglossal nerve and reaches the ramus of the mandible and turns round the posterior border of the horizontal ramus in company with the external maxillary vein and the Stenson’s duct and

Occipital artery is the smallest of the terminal branches of the common carotid artery. It passes upwards beneath the wing of atlas and during its course it gives off- Muscular branches to the ventral straight muscles of the head. Branches to the pharynx Palatine branches to the soft palate. It is then continued as the

Bicarotid trunk The bicarotid trunk continues the brachiocephalic artery after it detaches the right brachial artery. It is directed forwards beneath the trachea above the jugular confluence. It is related laterally to the vagus and recurrent laryngeal nerves. At the thoracic inlet, it bifurcates into two common carotid arteries-right and left. Common carotid artery Each

Common carotid artery and it’s branches are- Bicarotid trunk and common carotid artery Occipital artery External Maxillary artery Superficial temporal artery Internal maxillary artery Terminal branches External carotid artery Blood supply to brain

Intercostal arteries Of the 13 pairs of intercostal arteries, the first intercostal arises form dorsal artery. The second to fifth pair form the sub costal artery and the rest from the thoracic aorta. These aortic intercostal arteries arise in pairs from the dorsal face of the thoracic aorta at regular intervals.  Their origins (of each pair)

Oesophageal artery is a Visceral and unpaired artery. It arises from the inferior face of the thoracic aorta and passes downwards and divides into branches to supply the thoracic part of the oesophagus, posterior mediastinal lymph gland and lungs.

Brachial artery is a Visceral unpaired artery. It is the nutrient artery of the lungs. It arises from the inferior face of the aorta, descends across the left face of the oesophagus where it divides into right and left bronchial arteries of which the right is larger. Each artery reaches the root of the corresponding lung

The coronary arteries are right and left. The right coronary arteryis small and it arises from the anterior sinus of the aorta. Coronary arteries then passes forwards and somewhat downward to the right between the conus arteriosus and the right atrium to the right coronary groove in which it curves around to the right and backwards

Common brachiocephalic trunk is a large vessel arising from the convexity of the aortic arch within the pericardium. It is directed upwards and forward and it measures about 10 to 13 cm. It is between the two layers of the anterior mediastinum and crossed on the left by the left Vagus and cardiac nerves and
