4 th branchial arch on left forms aorta..common carotid? i think 3rd :?


  #3

THE 3 RD ARCH GIVES RISE TO R AND L COMMON CAROTID ARTERIS AND R AND L INTERNAL CAROTID ARTERIES.
THE 4 ARCH GIVES RISE TO THE R SUBCLAVIAN ARTEY AND TO THE ARCH OF THE AORTA ON THE L SIDE.

WHAT IS THE EMBROLOGY OF EXTERNAL CAROTID ARTERY??

Grrrrrrrrr smiling face Hmmm, I will doubtly say Arch 1 because my Bible (first Aid smiling face mentions Maxillary A comes from 1st arch.

Arch 1:Maxillary A
Arch 2:Stapes?? A
Arch 3: Common Carotids (letter C is the third in alphabet)
Arch 4: Systemic (meaning aorta and other arteries body---4 limbs)
Arch 6: Pulmonary Trunk and PDA

If I am wrong, I will throw my bible(first aid) and convert to another religion smiling face
