Vasculature of the Brain Flashcards
Anterior cerebral artery
Dorsal cortex
Superior and anterior aspects of the lateral hemispheres
Middle cerebral artery
Lateral hemisphere (also has penetrating branches)
Middle cerebral artery comes out of
Lateral fissure
Lenticulates Arteries
- Branches of
- Damaged by
Middle cerebral artery
Age, diabetes, hypertension & drug abuse
Posterior Cerebral Artery
Occipital lobe
Posterior & lateral midbrain
Temporal lobe
Superior Cerebellar Artery
Superior aspect of the cerebellum
Dorsal\lateral midbrain
Anterior Inferior Cerebellar Artery
Lateral pons
Basilar Artery
Ventral\Medial midbrain (penetrating branches)
Medial pons
Posterior Inferior Cerebellar Artery
Lateral brainstem and medulla
Dorsal\lateral midbrain
Anterior spinal artery
Medial medulla
What are watershed areas? Where are they located?
Broadly defined areas that occur between vessels, poorly vascularized so very sensitive to infarcts and low blood pressure

Ventral\Medial: Basilar
Dorsal\lateral: Superior cerebellar artery + Posterior cerebellar Artery
Artery of adamkiewicz
Segmental artery in lower thoracic region
If blocked = anterior spinal cord will die so reduce blood flow to medulla
