Where does the subclavian artery pass and what are the different parts?
-Passes lateral to trachea, between anterior and middle scalene. 1st part=medial to anterior scalene 2nd part= posterior to ant scalene 3rd part= 1st rib to become axillary a.
What are the subclavian artery branches? Mnemonic?
VIT C and D Vertebral Internal thoracic Thyrocervical trunk Costocervical trunk Dorsal scapular
Where does the vertebral artery pass through? Combines to become what?
-Travels through transverse foramina of C1-C6, through foramen magnum. -Combines left and right to become the basilar artery.

Inferior thyroid a containes inferior laryngeal a.
Where does the common carotid split? What leaves the carotid sheath?
Splits at C3. External carotid leaves sheath at this point.
Where does the internal carotid branch? What are its major branches?
Branches once it reaches the head.
- Ophthalmic
- Anterior and posterior ethmoid - Anterior and Middle Cerebral
- Posterior communicating
Opthalmic artery travels through what with what?
Travels with optic nerve through optic canal.
