|
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?
|
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.
|
|
|

|
The Posterior Cerebral Artery.
|
|
|
What does the Posterior Cerebral Artery supply?

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. |
