ANATOMY. 



3, Inferior thyroideal. 



a. Thyroid* branch. 



b. Ascending thyroid artery. 



c. Transverse artery of the neck. 



d. Transverse artery of the shoulder, 



or supra scapulary. 



3. Vertebral, a large trunk passing 

 through perforations in the transverse 

 processes of the cervical vertebrae, and 

 through the foramen magnum of the skull 

 to the brain, where it unites with its fel- 

 low of the opposite side, to form the ba- 

 silar artery. 



a. Inferior artery of the cerebellum. 

 it. Arteries to the spinal marrow. 



c. Superior artery of the cerebel- 



lum 



d. Posterior or deep seated artery of 



the brain. 



N. B. The arterial circle of Willis is a 

 large anastomosis ; by which the two ca- 

 rotids are joined together, and united also 

 to the basilar artery. 



4. Superior intercostal. 



5. Deep-seated cervical artery. 



6. Superficial cervical artery". 



Branches of the axillary artery. 



1. Superior or short thoracic. 



2. Inferior or long thoracic. 



3. Thoracic artery of the shoulder, 



4. Deep thoracic artery. 



5. fnfra-scapular artery. 



6. Posterior circumflex. 



7. Anterior circumflex. 



branches of the brachial artery. 



1. Various muscular branches. 



2. Profunda humeri major, or greater 

 deep-seated artery of the arm. 



3. Medullary artery of the humerus. 



4. Lesser deep-seated artery of the arm. 



5. Great anastomizing branch. 

 [ 6. Radial artery. 



7. Ulnar artery. 



The two last branches are those into 

 which the trunk of the brachial divides 

 :ttthe elbow. They run along the fore- 

 arm to the wrist. 



branches of the radial artery . 



1. Recurrent branch. 



2. Superficial artery of the palm. 



3. Branch to the back of the wrist. 



4. Branches to the back of the thumb 

 and fore-finger. 



The urtt-ry then enters the palm, and 

 forms the deep-seated arterial arch of the 

 palm. 



VOL I. 



Branches of the ulnnr artery. 



This vessel, when it has arrived at the 

 wrist, passes forwards into the palm of 

 the hand, more superficially than the ra- 

 dial, and forms the superficial arcU of the 

 palm. 



1. Ru current artery. 



2. Interosseous artery. 



a. Posterior branch. 



Interosseous recurrent. 



b. Anterior branch. 



3. Branch to the back of the hand. 



4. Deep palmar branch. 



5. Three large digital arteries. 



Jiranclies nf the descending portion of tlte 

 aorta in the chest. 



1. Common bronchial artery. 



2. Right and left bronchial arteries. 



3. Esophageal arteries. 



4. Lower intercostal arteries. 



The aorta pusses through the dia- 

 phragm at the lower part of the chest, and 

 takes the name of abdominal aorta. It 

 is still situated on the left side of the bo- 

 dies of the vertebrae, and at the fourth 

 lumbar vertebra it terminates by dividing 

 into the two common iliac trunks. 



Jiranches of the abdominal aorta. 



1. Right and left phrenic arteries. 



2. Cseliac artery. 



a. Coronary artery of the stomach. 



b. Hepatic artery. 



e. Duodeno-gastric, or gasfTjo- 

 epiploic artery. 



/3. Superior pyloric artery. 



y. Cystic artery. 

 r. Splenic artery. 



a,. Pancreatic arteries. 



/3. Short arteries to the sto- 

 mach. 



y. Left gastro-epiploic artery. 



3. Superior mesenteric artery. 



a. From 12 to 20 large branches to 



the small intestine. 



b. Middle colic artery. 



c. Ileocolic artery. 



4. Renal or emulgent arteries. 



5. Spermatic arteries. 



6. Inferior mesenteric artery. 



a. Left colic branch. 



b. Internal hemorrhoidal branch. 



7. Five pairs of lumbar arteries. 



8. Two common iliac arteries. 



9. Middle sacral artery. 



The common iliac quickly divides into 

 the external and internal iliac branches? 

 of which the former goes to the thigh, 

 the latter enters the cavity of the pelvis.
