A nerve cell conducts an electrochemical impulse because of changes that take place in the cell membrane. These changes allow movement of ions through the membrane, setting up currents that flow...Hobbie, Russell K.Professor of Physics, Emeritus University of MinnesotaRoth, Bradley J....
Schwann cells form a protective sheath around nerve fibres and ensure that nerve impulses are transmitted rapidly. If these cells are missing or damaged, severe neurological diseases may occur as a result. Researchers at Friedrich-Alexander-Universität Erlangen-Nürnberg (FAU) have succeeded in demon...
1.Any of the impulse-conducting cells that constitute the brain, spinal column, and nerves in vertebrates, consisting of a nucleated cell body with one or more dendrites and a single axon. 2.A similar impulse-conducting cell in invertebrates. In both senses also callednerve cell. ...
The meaning of NERVE IMPULSE is the progressive physicochemical change in the membrane of a nerve fiber that follows stimulation and serves to transmit a record of sensation from a receptor or an instruction to act to an effector —called also nervous im
试题来源: 解析 which [详解]考查定语从句。句意:这些神经细胞通过电脉冲连接起来。分析句子结构可知,此处应为关系词引导的非限制性定语从句,从句中缺少主语,所以使用关系代词,先行词nerve cells指的是物,that不能引导非限制性定语从句。故填which。反馈 收藏 ...
5.For example, Moody says that vitamin B12, in particular, helps maintain red blood cells and provides some of the coating on our nerves that help conduct nerve impulses. 6.Vocal cord paralysis occurs when the nerve impulses to the larynx — the area of the throat with the vocal cords —...
nerve cells, derived from human pluripotent stem cells (iPS cells). These are currently used in many cell-culture disease models. Another reason to significantly amplify the signals is if the researchers want to track nerve impulses in axons (fine, very thin fibrous extensions of a nerve cell)...
Definition: What are Nerve Cells?Essentially, nerve cells, also known as a neurons, are the active component of the nervous system. Neurons communicate with each other as well as with other cells through electric signals (nerve impulses), which in turn allows effector organs to respond to the...

neurotransmitters: 神经递质,transmits nerve impulses across a synapse 翻译:学习是大脑中神经连接模式改变的结果。神经细胞之间的连接被称为突触,突触是神经细胞未梢的分支之间的微小间隙。信息以被称为"神经递质"的分子形式跳过这些缝隙。根据目前的估计,人类大脑中有600万亿个突触。
