Exam 1: Ventricles and Cerebrospinal Fluid Flashcards

•Recall the material covered in Gross Anatomy concerning circulation, CSF and meninges. •Identify the components of the ventricular system and adjacent brain structures. •Identify the cisterns around the brain in brain slices or MRI/CT images. •Compare the composition of CSF to blood. •List the general functions of the structures that surround the ventricles.

Normal CSF contains only ___ to ___ cells (leukocytes) per ml

A

Production of CSF:

Normal CSF volume: about 120-150 ml

It is formed at a rate of about 0.5 ml/min (450-500 ml/day) → total pool of CSF is replaced 3 to 4 times/day

Normal CSF contains only 1 to 5 cells (leukocytes) per ml

82
Q

Reabsorption of CSF:

Reabsorbed through _____ _____ and returned to mostly the _____ _____ sinus.

Most of the CSF is transported through vesicles across the cells that line the _____ _____.

The CSF flow is dependent on the _____ hydrostatic pressure of CSF compared to venous blood.

A

Reabsorption of CSF:

Reabsorbed through arachnoid granulations (villi) and returned to mostly the superior sagittal sinus.

Most of the CSF is transported through vesicles across the cells that line the arachnoid granulations.

The CSF flow is dependent on the higher hydrostatic pressure of CSF compared to venous blood.
