Table 1.
Origin and frequency of branches of the middle cerebral artery in dromedaries.
| Branches of MCA | Origin | (%) of origin |
|---|---|---|
| Rostral olfactory | RCA | 80% |
| Rostral trunk of MCA | 20% | |
| Caudal olfactory | RCA | 35% |
| Caudal trunk of the MCA | 65% | |
| Orbital artery | Rostral trunk of MCA | 35% |
| Arises from a common trunk with the inferior frontal artery, known as the orbitofrontal trunk, which originates from the rostral trunk of the MCA | 65% | |
| Superior frontal | Rostral trunk of MCA | 60% |
| Common trunk with middle frontal and rostral parietal arteries | 5% | |
| Common trunk with inferior frontal and rostral parietal arteries | 5% | |
| Common descent with the middle frontal artery from the rostral trunk of the MCA | 30% | |
| Middle frontal | Rostral trunk of MCA | 65% |
| Shared descent with superior frontal artery from MCA’s rostral trunk | 30% | |
| Emerges from a common trunk (with superior frontal and rostral parietal arteries) from MCA’s rostral trunk | 5% | |
| Inferior frontal | Common trunk with orbital artery from the rostral trunk of the MCA | 65% |
| Rostral trunk of MCA | 30% | |
| Common trunk with superior frontal and rostral parietal arteries from MCA’s rostral trunk | 5% | |
| Rostral parietal | Rostral trunk of MCA | 60% |
| Caudal trunk of MCA | 30% | |
| Common trunk with superior and inferior frontal arteries | 5% | |
| Common trunk with middle and superior frontal arteries | 5% | |
| Middle parietal | Caudal trunk of MCA | 60% |
| Rostral trunk of MCA | 40% | |
| Caudal parietal | Caudal trunk of MCA | 60% |
| Rostral trunk of MCA | 40% | |
| Dorsal temporal | Caudal trunk of MCA | 60% |
| Common trunk with ventral and middle temporal arteries, arising from MCA’s main trunk | 30% | |
| Shared descent with the middle temporal artery | 10% | |
| Middle temporal | Appears in close proximity to the dorsal temporal branch | 10% |
| Common trunk with the dorsal and ventral temporal arteries | 30% | |
| Caudal trunk of MCA | 60% | |
| Ventral temporal | Caudal trunk of MCA | 60% |
| Common trunk with the dorsal and middle temporal arteries | 30% | |
| RCA | 10% |
The first column lists the different branches of the middle cerebral artery (MCA). The second column describes the origin of each branch, detailing any shared trunks with other arteries and their emergence from the MCA or the Rostral Cerebral Artery (RCA). The third column provides the percentage occurrence of each origin, as observed in our study.
