Question 1

What are 3 different parts of the subslavian artery

Answer 1

Thyrocervical branch - (medally of the anterior scalene)

Costal Cervical branch - ( posterior of the anterior scalene )

part 3 typically has no branches but its lateral of the anterior scalene

Question 2

What is medial to the anterior scanelene and what are its subsequent arteries?

Answer 2

• Thyrocervical trunk
  
  • inferior thyroid
    
    • variable
  • Transverse cervical artery
    
    • Supplies the rhomboids
    • passes ant to anterior scalene muscle
    • runs along with CN IX
  • Supraclavicular arteries
    
    • supply the infra/supra spinous fossa
    • b/w the steriocleidomastiod and the scalene anterior
• Vertabral artery
  
  • runs throught the fomale magnum
  • meets with other vertebrae artery to form basolic artery
  • passes through transverse formina 6 -1
• Interior throaric artery

Question 3

What is postior to the anterior scalene?

Answer 3

the costocervical trunk

Question 4

What is artery is superior to the pectoralis minor

Answer 4

It is the suprathoracic artery

supplies the posterior intercostal spaces 1 and 2 and portion of the posterior serratus anterior

1ST PART OF THE AXILLARY ARTERY

Question 5

What arteries are deep to the pectoralis minor?

Answer 5

THE SECOND PART OF THE AXILLARY artery

Thoaracicacromal artery

Supplies the

• pect. branch
• delt. branch.
• clavicalular branch
• acromial branch

Lateral thoraric artery

• lateral side of pec minor
• supplies pectoralis muscles, lymphn nodes and the breast

Question 6

WHat artiers run inferior to the pectoralis minor?

Answer 6

THE THRID PART OF THE AXILLARY ARTERY

• The post circum flex
  
  • passes around post. aspect. of surgical neck of humerous
  • anastomoses with ant. circum flex of humeral
  • runs with axillary nerve
  • supplies deltoids and triceps
  • quadrilateral space
• Anterior circum flex
• Subscapular
  
  • thoracodorsal
    
    • latissimus muscle
  • circumflex scapular

Question 7

What are the ananstomosing branches of the scapula ?

Answer 7

Suprascapular artery

dorsal scapular artery

posterior intercostal arteries

circumflex scapular artery

thoracodorsal artery

Question 8

What artery runs along the vertebral border of the scapula?

Answer 8

Dorsal scapular artery and it arises from either subclavian or the transverse cervical artery

Question 9

What do the lateral lymhatics follow?

Answer 9

cephallic vein

(chains if nodes in delta pectoral groove to axillary nodes )

Question 10

How do lumphatics flow medally?

Answer 10

From epitrochlear nodes to axillary

Question 11

where do lymph nodes lie brachially?

Answer 11

Lie medial to humerous near axillary and vein

Question 12

Where do pectoral lymph nodes lie?

Answer 12

lie beind pect minor with lateral thoracic artery

drain mammary gland

Question 13

Where are lymph nodes subscapularlly?

Answer 13

Lie along lower border of scapula with subscapular artery

drain the back

Question 14

What are the central nodes?

Answer 14

In axil;ary fat

recieve lymoh from all the above nodes drain to apical nodes behind clavicle
