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 ...
The serumlike fluid that circulates through the ventricles of the brain, the cavity of the spinal cord, and the subarachnoid space, functioning in shock absorption. Also calledspinal fluid. American Heritage® Dictionary of the English Language, Fifth Edition. Copyright © 2016 by Houghton Miffl...
Your doctor will use a procedure called a spinal tap or lumbar puncture. They'll take a sample of cerebrospinal fluid with a long, thin needle. You'll get a local anesthetic to numb the skin in the area, and the needle will go in between two of your vertebrae, the bones that surround...
The Relationship between Intelligence and Training Gains Is Moderated by Training Strategy We examined the relationship between training regimen and fluid intelligence in the learning of a complex video game. Fifty non-game-playing young adults were trained on a game called Space Fortress for 30 hours...
Whereas severe TBI can be diagnosed using a combination of clinical signs and standard neuroimaging techniques, mild TBI (also called concussion) is more difficult to detect This is where fluid markers of injury to different cell types and subcellular compartments in the central nervous system come ...
Extracellular fluids bathe the cells and conduct nutrients, cells, and waste products throughout the tissues of the body. Mature red blood cells, white blood cells, and platelets lie in a nearly colourless, protein-rich liquid calledplasma. This substance is diffused through the capillary walls ...
Cerebrospinal fluid (CSF), clear, colourless liquid that fills and surrounds the brain and the spinal cord and provides a mechanical barrier against shock. Formed primarily in the ventricles of the brain, the cerebrospinal fluid supports the brain and pr
Cerebrospinal fluid (CSF) in the subarachnoid space around the brain has long been known to drain through the lymphatics to cervical lymph nodes1–17, but the connections and regulation have been challenging to identify. Here, using fluorescent CSF trace
The two fluid compartments of the body, intracellular fluid and extracellular fluid, are in osmotic equilibrium. Water moves by facilitated diffusion through aquaporin channels across cell membranes. Nonpermeable solutes such as Na+ and Ca2 + are called effective solutes. Cellular volume is dependent ...
Cerebrospinal fluid is produced continuously in the brain and is normally absorbed into the bloodstream through protrusions in the outer membrane of the brain, called the dura mater. But in Jackson’s case, a tiny hole in her cribriform plate – a thin bone that separates her cranial and nasa...
