Fourth Ventricle

A diamond-shaped cavity located between the pons, medulla oblongata, and cerebellum, forming part of the ventricular system that circulates cerebrospinal fluid (CSF).

Key Functions:

• Receives cerebrospinal fluid (CSF) from the third ventricle via the aqueduct of Sylvius.
• Circulates CSF to the subarachnoid space.
• Contains the choroid plexus for CSF production.

Interacting Systems & Components:

• Pons (forms anterior wall)
• Medulla Oblongata (forms anterior wall)
• Cerebellum (forms posterior wall)
• Third Ventricle (connected to)
• Cerebrospinal Fluid (CSF) (circulates)
• Central Nervous System (part of ventricular system)
