Understanding the Structure of the Brain (Mod 3 video 1)

CSF circulation helps deliver nutrients and remove waste, with ongoing research into its crucial role in maintaining brain health and its effects on sleep.

CSF is produced by the choroid plexus, flows from the lateral ventricles through the interventricular foramina into the third ventricle, through the cerebral aqueduct into the fourth ventricle, exits to the subarachnoid space, and is reabsorbed into the venous circulation via arachnoid granulations.

The precentral gyrus is the primary motor cortex and the postcentral gyrus is the primary somatic sensory cortex.

Rostral for towards the nose and caudal for towards the tail.

The tentorium cerebelli.

The lateral ventricles are the largest cavities within the ventricular system of the brain, often compared to a ram's horn shape.

The longitudinal fissure.

Gyri and sulci increase the surface area of the brain for a higher capacity of neurons.

The temporal lobe.

The falx cerebri.

In the choroid plexus of the brain's ventricles.

Approximately 150 ml is in circulation with about 500 ml produced daily.

It collects venous blood from the brain and allows for the reabsorption of CSF.

The meninges are composed of three layers: dura mater, arachnoid mater, and pia mater. They protect the central nervous system.

It holds cerebrospinal fluid, providing cushioning and nutrient delivery for the brain.
