🗑
|
||||
| show | A The pos. intercostal arteries supply blood to the lateral thoracic wall. These have lateral mammary branches that reach the breast.
🗑
|
||||
| show | A The internal thoracic artery branches into ant intercostal arteries. These have perforating branches called "medial mammary branches" which supply blood to the breast.

🗑
|
||||
| Q What is significant about the medial pectoral n.? | show 🗑
|
||||
| Q The sternocostal head of the pec major by itself would extend the humerous from a flexed position. What would the clavicular head accomplish on its own? | show 🗑
|
||||

||||
| Q What is the origin of the pec minor? | show 🗑
|

| Q What mm. draws the scapula anterior AND inferior? | show 🗑
|
||||
| Q What mm. acts as an antagonist to the traps/scm on the clavicle? | show 🗑
|
||||
| show | A subclavius
🗑
|
||||
| show | A Yes, it is from the thoracoacromial artery, BUT it comes from the clavicular branch as opposed to the pectoral branch.
🗑
|
||||
| show | A serr. ant.
🗑
|
||||
| Q What is the innervation of the serr. ant.? What is unusual about the travel of this n.? | show 🗑
