What artery is indicated by the blue arrow?
The Anterior Spinal Artery.
What artery is indicated by the blue arrow?
The Left Posterior Spinal Artery.
There are 2 posterior spinal arteries, but only one anterior.
What artery is indicated by the blue arrow?
The Right Posterior Spinal Artery.
Where is the arterial blood flow from the Spinal Arteries derived from?
Most of the arterial blood flowing through the anterior and posterior apinal arteries is derived from the anterior and posterior Radicular Arteries.
What artery is indicated by the blue arrow?

What vertebral areas does it supply?
Right Vertebral Artery.

The vertebral arteries only supplies the upper cervical cord.
What vein is indicated by the red arrow?
Posterior Spinal Vein.
What vein is indicated by the red arrow?
Anterior Spinal Vein
Where do the anterior and posterior Spinal Veins drain?
They drain into the anterior and posterior Radicular Veins at each spinal level.
What artery is indicated by the blue arrow?
The Internal Carotid.
What artery is indicated by the blue arrow?
A Vertebral Artery.
Where do the Vertebral Arteries enter the cranium?
Through the Foramen Magnum.
Where do the Internal Carotid Arteries enter the cranium?
Through the Carotid Canal
What is the structure represented by the dashed line called?
The Circle of Willis.
What artery is indicated by the blue arrow?
The Anterior Cerebral Artery.
What artery is indicated by the blue arrow?
The (right) Middle Cerebral Artery.
Where does the Middle Cerebral Artery supply?
It supplies the lateral surfaces of the frontal, parietal and upper portions of the temporal lobes, and the anterior region of the lateral surface of the occipital lobe.
Where does the the Anterior Cerebral Artery supply?
It supplies the medial and superior surfaces of the frontal and parietal lobes.
What artery is indicated by the blue arrow?
The Posterior Cerebral Artery.
What does the Posterior Cerebral Artery supply?
It supplies the medial, posterior, and portions of the lateral surfaces of the Occipital Lobe, and the inferior surfaces of the Temporal Love.
What artery is indicated by the blue arrow?
Superior Cerebellar Artery
What artery is indicated by the blue arrow?
The Anterior Inferior Cerebellar Artery.
What artery is indicated by the blue arrow?
The Posterior Inferior Cerebellar Artery.
Where does the brainstem derive its blood supply?
The brainstem is supplied by branches of the Inferior Cerebellar Arteries (Anterior and Posterior) as well as groups of the Central Arteries and the Pontine Arteries.
The Posteromedial and Posterolateral groups of the Central Arteries.
Where does the Cerebellum derive its blood supply?
The Cerebellar Arteries.
Superior and Anterior Inferior off the Basilar.
Posterior Inferior off of the Vertebral Arteries.
How many groups of Central Arteries are there?
Four:
1. Anteromedial (off Anterior Communicating and Cerebral)
2. Anterolateral (off Middle Cerebral)
3. Posteromedial (off Posterior Communicating and Posterior Cerebral)
4. Posterolateral (Off the Posterior Cerebral Artery)
What are the Central Arteries?
Small arterial branches arising from the circle of Willis (or proximal branching arteries), that penetrate the base of the brain to supply deeply placed structures.
Where does the Anteromedial Group of the central arteries arise?

Where does it supply?
Chiefly from the Anterior Communicating and Anterior Cerebral Arteries.

Supply (portions of) the Hypothalamus.
Where do the Anterolateral Group of the central arteries arise?

What do they supply?
The Middle Cerebral Arteries.

Supply much of the "corpus striatum," and "the anterior limb, genu and much of the posterior limb of the internal capsule."
Where do the Posteromedial group of the central arteries arise?

What do they supply?
The Posterior Communicating Arteries and the Posterior Cerebral Arteries.

Supply much of the thalamus and hypothalamus, the subthalamus, and some medial portions of the midbrain.
Where does the Posterolateral Group of central arteries arise from?

What do they supply?
The Posterior Cerebral Artery.

Supply the posterior portion of the thalamus, as well as the tectum and some lateral portions of the midbrain.
What veins are indicated by the red arrows?
Superior Cerebral Veins
What vein is indicated by the red arrow?
The Superior Anastomotic Vein (of Trolard)
What vein is indicated by the red arrow?
The Inferior Anastomotic Vein (of Labbe)
What vein is indicated by the red arrow?
The Superficial Middle Cerebral Vein
What vein is indicated by the red arrow?
The Internal Jugular Vein
