|---|---|---|
| 13 | 4 - 5 | hindbrain (i.e., future posterior fossa) is supplied by two parallel neural arteries (or channels). These arteries obtain their blood supply from carotid-vertebrobasilar anastomoses given by the trigeminal artery (TA), the otic artery (OA), hypoglossal artery (HA), and the proatlantal artery (ProA) |
| 14 | 5 - 8 | basilar artery (BA) forms from the consolidation of the neural arteries. |
| 15 | 7 - 12 | vertebral arteries (VA) forms from transverse anastomoses between cervical intersegmental arteries, beginning with the ProA and proceeding downward to the 6th intersegmental artery, |
| 16 | 11 - 12 | (35 days) development of the middle cerebral artery (MCA) is first identified as small buds originating proximal to the anterior cerebral artery (ACA) on the anterior division of the primitive internal carotid artery (ICA). |
| 19 | 16 - 18 | middle cerebral artery (MCA) becomes more prominent, the plexi fuse into a single artery and further branches pierce the cerebral hemisphere. |
| 20 | 18 | stem of the ACA gives rise to the olfactory artery. |
| 21 | 21-24 | formation of the anterior communicating artery (ACOMM). |
