根据第二段中的“ With little gravity in space, fluids build up in an astronaut's head. Extra fluid collects in four chambers in the brain, called ventricles. "可知, 在太空中几乎没有重力的情况下,宇航员的头 部会积聚液体,多余的液体会聚集在脑室中。 由此可知,失重的环境导致液体聚集在宇航员 ...
Cerebrospinal fluid, or CSF, is a clear, colorless liquid that plays a crucial role in maintaining the health and function of your central nervous system. It cushions the brain and spinal cord, provides nutrients and removes waste products.
While in space, fluid-filled areas in the brains of astronauts fit in with microgravity by expanding (扩大). But after a space task, these structures might take three years to go back to normal, researchers report.At the brain's center sit four ventricles (脑室) filled with liquid that pr...
However, there is no study of in vivo CSF dynamics between ventricles in the embryonic brain. We address CSF movement using the zebrafish larva, during the major period of developmental neurogenesis. CSF movement was monitored at two stages of zebrafish development: early larva [pharyngula stage; ...
Crucially, the study shows that the flow of blood in the veins leading out of the cranium is closely linked to the flow of cerebrospinal fluid in and out of the brain's ventricles - cavities in the centre of the brain. In diseases such as normal pressure hydrocephalus these ventricles becom...
Cerebrospinal fluid - clear fluid found surrounding the brain and spinal cord (and in the ventricles of the brain). Cerebrospinal fluid acts as a cushion to protect the brain and spinal cord from damage, is involved in regulating blood flow, and helps to
: a colorless liquid that is comparable to serum, is secreted from the blood into the lateral ventricles of the brain, and serves chiefly to maintain uniform pressure within the brain and spinal cord Examples of cerebrospinal fluid in a Sentence Recent Examples on the Web Examples are ...
Sign In Sign Up Cerebrospinal Fluid (CSF)Cerebrospinal fluid (CSF) is clear fluid found in the brain and spinal cord. It is contained in cavities called ventricles. This colorless fluid is crucial in protecting the brain as it acts like a cushion. Its one-way flow to the blood is ...
However, in different species the mass and surface area of the choroid plexus becomes relatively smaller as the brain size increases. Also, the volume of the ventricles increases to a lesser degree with increasing brain size so that a larger brain has a proportionately smaller ventricular volume....
