What does cerebrospinal fluid flow between?
Cerebrospinal Fluid (CSF) flows through the four ventricles and then flows between the meninges in an area called the subarachnoid space. CSF cushions the brain and spinal cord against forceful blows, distributes important substances, and carries away waste products.
Where does cerebrospinal fluid flow within?
lateral ventricles
CSF circulates through the ventricular system and subarachnoid space that surrounds both the brain and spinal cord (Figure 51.21). Normally, CSF flows anteriorly in the lateral ventricles through the foramen of Monro and into the third ventricle.
Where does the cerebrospinal fluid flow quizlet?
6. CSF flows from the fourth ventricle (through the median and lateral apertures) into the subarachnoid space where it circulates of the surface of the brain and spinal cord.
What two layers does the cerebrospinal fluid flow between?
The CSF occupies the subarachnoid space (between the arachnoid mater and the pia mater) and the ventricular system around and inside the brain and spinal cord.
Why is lumbar puncture done?
A lumbar puncture (LP) or spinal tap may be done to diagnose or treat a condition. For this procedure, your healthcare provider inserts a hollow needle into the space surrounding the spinal column (subarachnoid space) in the lower back to withdraw some cerebrospinal fluid (CSF) or inject medicine.
How can I increase my CSF flow?
These techniques include massage and manipulation of the spine. Walking, stretching, cycling, heat, and yoga may all help SFF.
How does CSF circulate quizlet?
CSF flows down cerebral aqueduct to fourth ventricle. Choroid plexus in the fourth ventricle adds more CSF. CSF flows out Median and Lateral Apertures or through Central Canal of Spinal Cord. CSF fills subarachnoid space and bathes external surfaces of brain and spinal cord.
Which meninx is the toughest?
The outer layer is the toughest and thickest. It is called the dura mater (“DUR-ah MAY-ter”.) The middle layer is the arachnoid mater (“ah-RACK-noid MAY-ter”.) The inner-most layer lays directly on the nervous tissue of the brain or spinal cord, and is called the pia mater (“PIE-ah MAY-ter”.)
Are lumbar punctures safe?
A lumbar puncture is safe for most people. Some people get a severe headache known as a “spinal headache” caused by CSF leakage. Rare complications include back or leg pain, accidental puncture of the spinal cord, bleeding in the spinal canal, and brain herniation caused by a sudden decrease of CSF pressure.
Is lumbar puncture painful?
A lumbar puncture is where a thin needle is inserted between the bones in your lower spine. It should not be painful, but you may have a headache and some back pain for a few days.
