Cerebral Arterial Supply

Detailed examination of brain blood supply:

Vocabulary: The Circle of Willis is a circular arterial structure at the base of the brain.

Key vessels:

• Internal carotid arteries
• Middle cerebral arteries
• Anterior cerebral arteries
• Posterior cerebral arteries

Cerebral Arteries Continued

Advanced arterial anatomy:

Definition: The internal carotid arteries supply over 80% of the cerebrum with oxygenated blood.

Detailed vessel network:

• Anterior communicating artery
• Posterior communicating artery
• Basilar artery system

Lateral View and Lobes of the Brain

The lateral view of brain labeled shows the four major lobes and their primary functions. The cerebral cortex demonstrates remarkable functional specialization across different regions.

Definition: The cerebral cortex is the outermost layer of the brain, divided into four specialized lobes that control different aspects of cognition and behavior.

The primary motor cortex is located in which lobe question is answered clearly - it resides in the frontal lobe. Each lobe has distinct functions:

Highlight: The frontal lobe manages personality, behavior, emotions, judgment, planning, and motor functions.

Example: The temporal lobe processes language understanding through Wernicke's area, while also managing memory and hearing functions.

Vocabulary: Synapses - The trillion connections between neurons that enable communication within the brain.
