In neuroanatomy, the ventricular system is a set of four interconnected cavities known as cerebral ventricles in the brain. [1] [2] Within each ventricle is a region of choroid plexus which produces the circulating cerebrospinal fluid (CSF). The ventricular system is continuous with the central canal of the spinal cord from the fourth ventricle ...

Fourth ventricle location shown in red (E), pons (B); the floor of the ventricle is to the right, the roof to the left. The fourth ventricle has a roof at its upper (posterior) surface and a floor at its lower (anterior) surface, and side walls formed by the cerebellar peduncles (nerve bundles joining the structure on the posterior side of the ventricle to the structures on the anterior side).
Lateral ventricles and horns The lateral ventricles connected to the third ventricle by the interventricular foramina. Each lateral ventricle takes the form of an elongated curve, with an additional anterior-facing continuation emerging inferiorly from a point near the posterior end of the curve; the junction is known as the trigone of the lateral ventricle.

The brain controls most of the activities of the body, processing, integrating, and coordinating the information it receives from the sensory nervous system. The brain integrates the instructions sent to the rest of the body. The cerebrum, the largest part of the human brain, consists of two cerebral hemispheres.
Ventricular system – set of structures containing cerebrospinal fluid which bathes and cushions the brain and spinal cord within the skull; Cranial nerve – neuron bundles that connect to the brain on one end, and to locations outside the brain on the other, without having a junction inside the spinal column
The identification of the heart as the seat of emotions in particular is due to the Roman physician Galen, who also located the seat of the passions in the liver, and the seat of reason in the brain. [119] The heart also played a role in the Aztec system of belief. The most common form of human sacrifice practiced by the Aztecs was heart ...
