Fig. 2.7 Ventricular system: (a) interconnected ventricles; (b) components of the lateral ventricle
(inferior view)
2.2.4 Ventricular System
The ventricular system contains four interconnected cerebral ventricles (cavities)
filled with cerebrospinal fluid (CSF) (Fig. 2.7a):
• Left and right lateral ventricles
• Third ventricle
• Fourth ventricle
CSF is secreted mainly in the choroid plexus (a network of vessels) and circulates
from the lateral ventricles through the paired interventricular foramina (of Monro)
to the third ventricle and then via the aqueduct to the fourth ventricle (Fig. 2.7a).
The lateral ventricles are the largest and each contains (Fig. 2.7b):
• Body (or central portion)
• Atrium (or trigon)
• Horns
– Frontal (anterior)
– Occipital (posterior)
– Temporal (inferior)
