(a) Describe the fluid spaces of the brain and spinal cord. (b) What are the name and the function of the fluid that circulates within these spaces? Explain how the nervous system produces and reabsorb cerebrospinal fluid and why the body bathes the brain and spinal cord in this special...
A choroid plexus cyst is a small area where some fluid builds up in the choroid plexus. The choroid plexus is a specialized tissue that produces the cerebrospinal fluid. These small cyst are common during embryonic development. They are detected during a regular ultrasound and they tend to ...
What structure of the brain ventricles produces cerebrospinal fluid (CSF)? Which of the following helps to protect the brain? (a) The blood-brain barrier (b) The bones of the skull (c) The cranial meninges (d) The CSF (e) All of the above are correct. What part of the brain is re...
The adaptive immune system produces antibodies directed against specific pathogens it has encountered. In addition, the innate immune system produces antibodies against a wide range of further epitopes. These naturally occurring antibodies include autoantibodies, that is, antibodies recognising endogenous ...
The MIC8 DNA vaccine induces strong humoral and cellular immune responses and produces cytokines such as IL-15 and IL-21, which were protective against T. gondii challenge28,29. SAGs are mainly involved in the recognition and adhesion of T. gondii to host cells and the early invasion process...
Cerebrospinal fluid (CSF) assays of specific proteins as well as protein signatures in CSF have potential utility as biomark- ers. Of the proteins that undergo abnormal conformational changes that enhance their aggregation and deposition in brain in AD, Ab1- 42, the ratio of Ab1-42:Ab1-40, ...
Studies are giving doctors more therapy options for the condition, a better understanding of what produces it, and the knowledge to diagnose it earlier. Stem-cell and genetic research may someday help scientists repair broken nerves or stop the disease before it induces damage. ...
Damage to this area of the brain produces what is called sensory aphasia, in which patients cannot understand language but can still produce sounds. Frontal lobe -- The frontal lobe is involved in motor skills (including speech) and cognitive functions. The motor center of the brain (pre-...
What structure of the brain ventricles produces cerebrospinal fluid (CSF)? What structure of the eye is a clear window at the front of the eye that bends light rays? Which cranial nerve provides the parasympathetic motor innervation that controls pupil size and lens shape? A) Ophthalmic division...
The cerebrospinal fluid is found in the subarachnoid space, ventricles of the brain, and the central canal of the spinal cord. What structure produces this fluid? The cerebrospinal fluid is found in the subarachnoid space, ventricles of the brain, and central canal of t...
