Ventricular System and Brain Development: Key Structures and Stages

What are the three primary vesicles in brain development?

Prosencephalon, Mesencephalon, Rhombencephalon.

What are the secondary vesicles derived from the prosencephalon?

Telencephalon and Diencephalon.

What secondary vesicle is derived from the mesencephalon?

Mesencephalon itself remains as a secondary vesicle.

What are the two secondary vesicles derived from the rhombencephalon?

Metencephalon and Myelencephalon.

What is the function of the ventricular system?

It produces cerebrospinal fluid (brain juice).

Where are the lateral ventricles located?

In the telencephalon (cerebrum).

What connects the lateral ventricles to the third ventricle?

The interventricular foramen.

Where is the third ventricle located?

In the diencephalon.

What is the mesencephalic aqueduct?

A channel located in the mesencephalon that connects the third and fourth ventricles.

What is another name for the fourth ventricle?

Rhomboid fossa.

Where is the fourth ventricle located?

Deep to the cerebellum, spanning two divisions of the brainstem.

What are the lateral apertures of the fourth ventricle also known as?

Foramina of Luschka.

What is the median aperture of the fourth ventricle called?

Foramen of Magendie.

What causes the transition from the neural tube to the brain?

Brain flexures.
