Cerebrospinal Fluid Functions | Introduction| Composition

What is Cerebrospinal Fluid (CSF)

Cerebrospinal Fluid one of the significant Body Fluid which is free from or Devoid of Red Blood Cells. Due to this characteristic CSF appear Colorless. While�CSF is formed by the Choroid Plexus of Brain. It is basically an ultrafiltrate form of the plasma. In the central ventricles, spinal canal, and subarachnoid spaces Cerebrospinal Fluid (CSF) is present. Cerebrospinal Fluid Functions�are described below:

Cerebrospinal Fluid Analysis

Analysis of the�Cerebrospinal Fluid (CSF) shows that it consists of the following Composition:

CSF Normal Values

1. Cerebrospinal Fluid (CSF) is alkaline fluid and its pH same as blood has which range is (7.35 to 7.40).
2. Cerebrospinal Fluid (CSF) Total Volume is 100-150ml. But in Adults,�Cerebrospinal Fluid (CSF) volume ranges from140 to 270 ml.
3. Cerebrospinal Fluid (CSF) has a Specific Gravity ranges from 1.003 to 1.008.
4. The rate of production of�Cerebrospinal Fluid (CSF)�ranges�between 0.2 – 0.7 ml per minute or 600-700 ml per day.
5. The circulation of CSF is helpful by the Ciliary movement of Ependymal Cells and Choroid Plexus Pulsations.
6. Normally Cerebrospinal Fluid (CSF) is basically an opaque, clear, colorless and transparent fluid.

Cerebrospinal Fluid Composition

Cerebrospinal Fluid (CSF) consist of more or less similar composition to that of Plasma. But�Cerebrospinal Fluid (CSF) didn’t contain Colloids. While its composition values are given below:

• Protein� � � � � � � �20-45 mg /dl

• glucose� � � � � � �40-80 mg /dl

• Chloride� � � � � � 700-750 mg /dl

• Urea� � � � � � � � � � 20 – 40 mg/dl

• Uric acid� � � � � � 1 – 7 mg/dl

• Sodium� � � � � � � � 300 – 350 mg/dl

• Potassium� � � � � 11-15 mg/dl

• Calcium� � � � � � � 4 – 5 mg /dl

• Phosphorous� � 1 – 1.5 mg/dl

Cerebrospinal Fluid Functions

Cerebrospinal Fluid Functions�are given below:

1. Cerebrospinal Fluid (CSF) make a Jacket around the Brain and Spinal Cord. Which acts as the Protective Jacket.
2. Cerebrospinal Fluid (CSF) act as a cushioned material and balance Pressure on the nervous structures like Brain and Spinal Cord.
3. Its�significant function is to regulate the� Cranium contents by acting as a Reservoir.
4. Cerebrospinal Fluid (CSF)� also plays a vital role in the nutrient exchange between the Nervous System.
5. It also helps�in the removal of waste material from the Brain.
6. Cerebrospinal Fluid (CSF)� plays a significant role in maintaining Homeostasis and� Central Nervous System Metabolism.

Cerebrospinal Fluid Leak

Due to Cerebrospinal Fluid Leakage, the fluid composition of CSF is changed and caused the following diseases in Human Beings:

1. Meningitis
2. Encephalitis
3. Neurosyphilis
4. Poliomyelitis
5. Disseminated sclerosis
6. Spinal and brain tumor
7. Cerebral hemorrhage
