Quick Answer: How Does The CSF Circulate?

Where does the cerebrospinal fluid CSF circulate quizlet?

CSF flows from the subarachnoid space at the base of the brain rostrally over the cerebral hemispheres or down the spinal cord..

What are the functions of CSF?

While the primary function of CSF is to cushion the brain within the skull and serve as a shock absorber for the central nervous system, CSF also circulates nutrients and chemicals filtered from the blood and removes waste products from the brain.

What is normal CSF pressure?

Normal CSF contains 0-5 mononuclear cells. The CSF pressure, measured at lumbar puncture (LP), is 100-180 mm of H2O (8-15 mm Hg) with the patient lying on the side and 200-300 mm with the patient sitting up.

What happens if CSF flow is blocked?

The body typically produces enough CSF each day and absorbs the same amount. However, when the normal flow or absorption of CSF is blocked it can result in a buildup of CSF. The pressure from too much CSF can keep the brain from functioning properly and cause brain damage and even death.

What produces cerebrospinal fluid for what purpose quizlet?

The protein-poor serous plasma filtrate which is secreted by choroid plexus cells in each of the four ventricles of the brain and which circulates through the ventricles of the brain, the central canal of the spinal cord, and the subarachnoid space, and returns to the blood stream at the arachnoid villi; it functions …

What happens if CSF does not drain properly?

CSF is constantly being made and absorbed by your body. CSF moves through ventricles before it drains out and gets absorbed into your bloodstream. When CSF cannot drain properly, the fluid pressure may cause the ventricles to swell.

Does CSF go to the heart?

Normal route of CSF from production to clearance is the following: From the choroid plexus, the CSF flows to the lateral ventricle, then to the interventricular foramen of Monro, the third ventricle, the cerebral aqueduct of Sylvius, the fourth ventricle, the two lateral foramina of Luschka and one medial foramen of …

How does CSF circulate around the spinal cord?

According to the traditional understanding of cerebrospinal fluid (CSF) physiology, the majority of CSF is produced by the choroid plexus, circulates through the ventricles, the cisterns, and the subarachnoid space to be absorbed into the blood by the arachnoid villi.

How do you remember CSF flow?

The flow of CSF MnemonicOK Let’s get to work! … Lateral Ventricle → foramen Monroe→Third ventricle → Sylvius Aqueduct→ fourth ventricle→ foramen Magendie → foramen Lushka→Subarachnoid space→Arachnoid Villi→Superior Sagittal Sinus.The mnemonic is.Lady Monroe’s Three Siblings Fought, for Magical Lights Seeing Arrogant Seniors.

What is the last spot where CSF circulates?

What is the last spot where CSF circulates before being resorbed by the circulatory system? visual and auditory reflex movements of the head and neck. If you are reading and you unexpectedly hear a loud noise, your head generally snaps up.

What increases CSF production?

The increased CSF production is the result of an increased activity of Na+-K+ ATPase at the choroid plexus level, which establishes a sodium gradient across the choroid epithelial cells, as well as of an elevated CBF (66).

Where does CSF flow?

CSF flows from the lateral ventricle to the third ventricle through the interventricular foramen (also called the foramen of Monro). The third ventricle and fourth ventricle are connected to each other by the cerebral aqueduct (also called the Aqueduct of Sylvius).
