What does the CSF do to protect the brain?

What is CSF and its function?

The main functions of CSF are to cushion the brain and spinal cord when they’re struck with mechanical force, to provide basic immunological protection to the CNS, to remove metabolic waste, as well as to transport neuromodulators and neurotransmitters.

What are the 4 functions of CSF?

Cerebrospinal fluid has four major functions: (1) physical support of neural structures, (2) excretion and “sink” action, (3) intracerebral transport, and (4) control of the chemical environment of the central nervous system. Cerebrospinal fluid provides a “water jacket” of physical support and buoyancy.

What are the three main functions of CSF?

Cerebrospinal fluid has three main functions:

  • Protect brain and spinal cord from trauma.
  • Supply nutrients to nervous system tissue.
  • Remove waste products from cerebral metabolism.

What is CSF used to diagnose?

Infections, such as meningitis and encephalitis—testing is used to determine if infection is caused by bacteria, viruses or, less commonly, by Mycobacterium tuberculosis, fungi or parasites, and to distinguish them from other conditions. CSF testing may also be used to detect infections of or near the spinal cord.

How does CSF circulate?

CSF flows from the lateral ventricles to the third ventricle via the foramen of Monro. From here, it flows across the cerebral aqueduct of Sylvius to the fourth ventricle and onto the subarachnoid space through the apertures of Magendie and Luschka [3].

How does CSF maintain homeostasis?

Chemical stability: CSF flows throughout the inner ventricular system in the brain and is absorbed back into the bloodstream, rinsing the metabolic waste from the central nervous system (CNS) through the blood-brain barrier.

Why do doctors take spinal fluid?

During a spinal tap (lumbar puncture), a healthcare provider withdraws cerebrospinal fluid. This test can detect meningitis, leukemia and other illness. Providers also use spinal taps to give spinal anesthesia (epidural) and medications.

What happens if you have too much cerebrospinal fluid?

Cerebrospinal fluid normally flows through the ventricles and bathes the brain and spinal column. But the pressure of too much cerebrospinal fluid associated with hydrocephalus can damage brain tissues and cause a range of brain function problems.

What does red blood cells in CSF indicate?

Finding red blood cells in the CSF may be a sign of bleeding. However, red blood cells in the CSF may also be due to the spinal tap needle hitting a blood vessel. Additional conditions which this test may help diagnose include: Arteriovenous malformation (cerebral)
