BRANCHES OF THORACIC & ABDOMINNAL AORTA

Branches of thoracic aorta IN ADDITION TO THE CORONARY ARTERIES

AND COMMON BRACHIO-CEPHALIC TRUNK, THE THORACIC PART OF AORTA GIVES OFF BRANCHES TO THE THORACIC WALLS AND VISCERA AND TO SPINAL CORD AND ITS MEMBRANE.

(1).VISERAL BRANCHES…………….BRONCHIAL AND OESOPHAGEAL

(2).PARIETAL BRANCHES…………..INTERCOSTAL AND PHRENIC

(1) VISCERAL BRANCHES

BRONCHIAL-OESOPHAGEAL ARTERY: ORIGIN: ARISES AT THE SIXTH THORACIC VERTEBRA

FROM AORTA-IT DESCENDS OVER THE RIGHT FACE OF THE AORTA TOWARDS BIFURCATION OF TRACHEA AND DIVIDED INTO BRONCHIAL ANAOESOPHAGIAL BRANCHES.

BRONCHIAL ARTERY: IT CROSSES THE LEFT FACE OF OESOPHAGOUS

TO THE BIFURCATION OF TRACHEA WHERE IT DIVIDES INTO RIGHT AND LEFT BRANCHES.EACH ENTER INTO HILUS OF CORRESPONDING LUNG.

Cont…

OESOPHAGEAL ARTERY: IT IS SMALL VESSEL WHICH PASSES

BACKWARD DORSAL TO THE OESOPHAGOUS IN THE POSTERIOR MEDIASTINUM AND ANASTOMOSIS WITH THE OESOPHAGEAL BRANCH OF THE GASTRIC ARTERY AND GIVES OFF BRANCHES WHICH PASSES BETWEEN THE LAYERS OF LIGAMENT OF THE LUNGS.

PARIETAL BRANCHES:

INTERCOSTAL ARTERIES: *FIRST ARISE FROM DEEP CERVICLE ARTERY *NEXT THREE ARISE FROM SUBCOSTAL BRANCH

OF DORSAL ARTERY *REMAINDER ARISE FROM AORTA 1.AORTICINTERCOSTALS ARTERIES: ARISE FROM AORTA IN PAIRES CLOSE TOGETHER.

THE FIFTH AND SIXTH SPRINGS FROM A COMMON STEM. EACH PASSES THE BODY OF VERTEBRA TO INTERCOSTALS SPACE. IT DIVIDES INTO

DORSAL BRANCHES VENTERAL BRANCHES

DORSAL BRANCHES: IT GIVES OFF SPINAL BRANCHES WHICH

PASSES THROUGH INTERVERTEBERALFORAMEN.A MUSCULAR BRANCH PASSES TO MUSCLE AND SKIN OF BACK.

  VENTERAL BRANCHES: IT IS MUCH LARGE. ORIGIN: IT DESCEND IN MIDDLE OF

INTERCOSTALS SPACE BETWEEN INTRCOSTAL MUSCLES.

SUPPLIES:IT SUPPLIES INTERCOSTALSMUSCLE,THERIBS,AND PLEURA

PHARENIC ARTERIES: ORIGIN: TWO OR THREE SMALL

BRANCHES WHICH ARISE AT HIATUS AORTICUS FROM VENTERAL ASPECT OF AORTA.

SUPPLIES: THEY SUPPLIES CRURA OF DIAPGRAM.

BRANCHES OF ABDOMINAL AORTA:

THESE BRANCHES SUPPLIES

1) WALLS OF ABDOMINAL CAVITY

2) SOME BRANCHES SUPPLIES SPINAL CORD

3) SOME EXTEND INTO PELVIS AND SACROTUM

VISCERAL BRANCHES

(1).COELIAC ARTERY

IT IS UN PAIRED VESSEL ORIGIN: ARISE FROM VENTERAL ASPECT OF

AORTA IT IS FURTHER DIVIDED INTO THREE BRANCHES GASTRIC ARTERY IT GIVES OFF OESOPHAGOUS AND PANCREATIC

BRANCHES IT DIVIDED BEHIND THE CARDIA INTO ANTERIOR

AND POSTERIOR BRANCHES

Cont… ANTERIOR BRANCHES: THEY SUPPLIES THE PARIETAL SURFACE OF

STOMACH POSTERIOR BRANCHES: THEY SUPPLIES THE VISCERAL SURFACE OF

STOMACH OESOPHGEAL BRANCHES: IT PPASSES THROUGH HIATUS OESOPHAGOUS

INTO THORACIC CAVITY ABOVE THE OESOPHAGOUS AND ANASTOMOSES WITH THE OESOPHAGEAL BRANCH OF BRONCHO-OESOPHAGEAL CAVITY.

HEPATIC ARTERY: LARGER THAN GASTRIC IT PASSES FORWARD AND TO THE RIGHT AND VENTERALLY ON DORSAL

SURFACE OF PANCREAS IT DIVIDED INTO 3-4 BRANCHES WHICH ENTER THE PORTAL FISSURE OF

LIVER IT ALSO GIVES OFF CO-LATERAL BRANCHES

PANCREATIC BRANCHES: GIVES OFF AN ARTERY CROSSES THE PANCREAS

  PYLORIC ARTERY: ORIGIN: ARISE FROM DUOENUM AND GIVES OFF ITS BRANCHES TO

PYLORUS.

  GASTRO-DUODENAL ARTERY: ORIGIN: IT ALSO ARISE FROM DUODENUM IT ALSO GIVES TWO BRANCHES.

  RIGHT GASTRO EPIPLOIC ARTERY: IT SUPPLIES STOMACH AND DUODENUM PANCREATIC-DUEDENAL ARTERY: IT SUPPLIES PANCREAS AND DUEDENUM

SPLENIC ARTERY: LARGEST BRNCH OF CORLIAC ARTERY. IT PASSES THE LEFT EXTRIMITY OF PANCRAS AND CROSS

THE STOMACH. IT GIVES OFF

  PANCREATIC BRANCHES: SUPPLIES: THEY SUPPLIES THE LEFT EXTRIMITY OF

PANCREAS

  SPLENIC BRANCHES: SUPPLIES: THEY SUPPLIES THE SPLEEN SHORT GASTRIC BRANCHES: SUPPLIES:IT SUPPLIES YHE GREATER CURVATURE OF

STOMACH   LEFT GATRO EPIPLOIC ARTERY: IT IS CONTINUATION OF SPLENIC ARTERY SUPPLIES:IT SUPPLIES THE GREATER CURVATURE OF

STOMACH

(2) ANTERIOR MESENTRIC

ORIGIN: ARISE FROM VENTERAL FACE OF

AORTA AT FIRST LUMBER VERTEBRA.

IT IS LARGE UNPAIRED TRUNK IT PASSES VENTERALLY BETWEEN VANA CAVA AND ADRENAL

IT GIVES OFF BRANCHES…..

LEFT BRANCH: IT GIVES OFF 15-20 BRANCHES OF

SMALL INTESTINE RIGHT BRANCHES: IT GIVES OFF SMALL BRANCHES ILEAL: IT PASSES THE TERMINAL

PART OF ILEUM LATERAL COCCYGEAL ARTERY: IT

PASSES BETWEEN COECUM AND ORIGIN OF COLON

MEDIAL COCCYGEAL ARTERY: IT PASSES ALONG THE APEX OF COECUM

VENTERAL COLIC ARTERY: IT PASSES THE VENTERAL SURFACE OF COLON WHERE IT UNITES WITH DORSAL COLIC ARTERY

ANTERIOR BRANCHES :IT GIVES OFF

DORSAL COLIC ARTERY: IT PASSESS THE GREATER COLON AND JOINS THE VENTERAL COLIC ARTERY

MEDIAL COLIC ARTERY: IT PASSES THE SMALL COLON AND ENTER THE COLIC MESENTRY

RENAL RIGHT & LEFT ARE RELATIVELY LARGE

NESSELS WHICH ARISES FROM AORTA NEAR THE ANTERIOR MESENTRIC.

RIGHT ARTERY: IT IS LONGER OF THE TWO; IT CROSS THE DORSAL SURFACE OF VENA

CAVA AT RENAL HILUS IT DIVIDES INTO SEVERAL

BRANCHES LEFT ARTERY: IT IS SHORTER; IT PASSES DIRECTLY OUTWARD TO THE
