What is cerebrospinal fluid and what is its function? Formed primarily in the ventricles of the brain, the cerebrospinal fluidsupports the brain and provides lubrication between surrounding bones and the brain and spinal cord. When an individual suffers a head injury, the fluid acts as a cushion,...
Where is most of the water in the body located? a. Plasma. b. Cells. c. Between body cells. d. Bladder. e. Cerebrospinal fluid and glands. Fill in the blank. In the CNS, ___ are cells that line the fluid-filled cavities and which produce, transport, and circulate the fluid surrou...
Ependymal cells produce CSF (cerebrospinal fluid), which is located within the ventricles of the brain and in the subarachnoid space that surrounds the brain and spinal cord. Aside from allowing the brain to float in the skull, CSF acts as a cushion against traumaand also helps wash away some...
The new study led by Boston University scientists has discovered that the brain waves generated right before our deep sleep stage helps produce a "cleaning" fluid. This fluid protects our brain from toxins associated with diseases such as Alzheimer's. Lewis suspected that the cerebrospinal(脑脊髓...
(a) What is the serous membrane? (b) What does it do? (c) What does it produce? By what process does gas exchange occur in the lungs and tissues? What is the function of cerebrospinal fluid? Describe how different categories of solutes are reabsorbed from the lumen of PCT to the per...
Figure 1. (a) A lumbar puncture is used to take a sample of a patient’s cerebrospinal fluid (CSF) for testing. A needle is inserted between two vertebrae of the lower back, called the lumbar region. (b) CSF should be clear, as in this sample. Abnormally cloudy CSF may indicate an...
C. produce cerebrospinal fluid. D. form myelin sheaths. E. are part of the choroid plexus. CSF flows into one of the meningeal spaces. Which one? From which brain ventricle does CSF enter these additional spaces? Name two passageways in the floor of the skull for major blood vessels that...
Excretory-secretory antigens (ESA) produced by tachyzoites account for most circulating antigens in the serum and cerebrospinal fluid of the host. ESA immunization can improve animal survival rates by reducing parasitemia of highly virulent strains and controlling infections4. Subcutaneous injection of...
What is the purpose of brain ventricles? Aside from cerebrospinal fluid, your brain ventricles are hollow. Their sole function isto produce and secret cerebrospinal fluid to protect and maintain your central nervous system. Which ventricle is more muscular?
This is a pathological condition which occurs as a result of an imbalance between the production and absorption of this fluid, the Cerebrospinal Fluid – CSF. Under normal conditions, circulation and absorption of the CSF create a perfect equilibrium between secretion and absorption of CSF. The ...
