1. 𝗔1 segment (Precommunicating segment) – Extends from the internal carotid artery bifurcation to the anterior communicating artery.
2. 𝗔2 segment (Postcommunicating segment) – Extends from the anterior communicating artery to the region just anterior to the genu of the corpus callosum.
3. 𝗔3 segment (Pericallosal segment) – Courses around the genu of the corpus callosum.
4. 𝗔4 segment (Supracallosal segment) – Runs along the superior surface of the body of the corpus callosum.
5. 𝗔5 segment (Postcallosal segment) – Extends over the posterior portion of the corpus callosum.

•During embryonic development, the arterial system arises from F͟i͟v͟e͟ key sources:
1.𝐕𝐞𝐧𝐭𝐞𝐫𝐚𝐥 𝐚𝐨𝐚𝐫𝐭𝐢𝐜 𝐒𝐚𝐜:
- Forms the roots of the ascending aorta and brachiocephalic trunk.
2.𝐏𝐡𝐚𝐫𝐲𝐧𝐠𝐞𝐚𝐥 𝐀𝐫𝐜𝐡 (aortic arches):
•Form portions of the carotid arteries, subclavian arteries, aortic arch, and pulmonary arteries.
3.𝐃𝐨𝐫𝐬𝐚𝐥 𝐀𝐨𝐚𝐫𝐭𝐚𝐞:
•For descending aorta and give rise to intersegmental arteries that become intercostal, lumbar, and vertebral arterie.
4.𝐕𝐢𝐭𝐞𝐥𝐥𝐢𝐧𝐞 𝐀𝐫𝐭𝐞𝐫𝐢𝐞𝐬:
•Supply the yolk sac initially and later become the celiac trunk, superior mesenteric artery, and inferior mesenteric artery.
5.𝐔𝐦𝐛𝐢𝐥𝐢𝐜𝐚𝐥 𝐀𝐫𝐭𝐞𝐫𝐢𝐞𝐬:
•Persist proximally as the internal iliac arteries while regressing distally to become the medial umbilical ligaments.

The circumventricular organs (CVOs):
𝐃𝐫𝐚𝐰 𝐯𝐬. 𝐌𝐑𝐈

- specialized structures located around the 3ʳᵈ & 4ᵗʰ ventricles.
- Thy lack the blood-brain barrier (BBB).

1. 𝐒𝐮𝐛𝐟𝐨𝐫𝐧𝐢𝐜𝐚𝐥 Organ (SFO): monitors osmolarity and blood pressure (e.g., angiotensin II), allowing it to regulate thirst and cardiovascular function.
2. 𝐎𝐫𝐠𝐚𝐧𝐮𝐦 𝐕𝐚𝐬𝐜𝐮𝐥𝐨𝐬𝐮𝐦: smolarity and solute concentration, for regulating thirst and vasopressin secretion.
3. 𝐀𝐫𝐞𝐚 𝐏𝐨𝐬𝐭𝐞𝐫𝐞𝐦𝐚: Detects toxins in the blood and triggers vomiting (chemoreceptor trigger zone).
4. 𝐌𝐞𝐝𝐢𝐚𝐧 𝐄𝐦𝐢𝐧𝐞𝐧𝐜𝐞: route to hypothalamic hormones (CRH, TRH) to the portal circulation.
5. 𝐏𝐢𝐧𝐞𝐚𝐥 𝐆𝐥𝐚𝐧𝐝: releases melatonin directly into the bloodstream, requiring free exchange of hormones for circadian rhythm.
6. 𝐍𝐞𝐮𝐫𝐨𝐡𝐲𝐩𝐨𝐩𝐡𝐲𝐬𝐢𝐬( Posterior Pituitary): secretes oxytocin and vasopressin directly into the blood.
7. 𝐒𝐮𝐛𝐜𝐦𝐦𝐢𝐬𝐬𝐮𝐫𝐚𝐥 Organ: secretes glycoproteins into the cerebrospinal fluid (CSF), contributing to the development and function of the brain’s ventricular.
