Impulse (physiology) - Impulse

Japanese: インパルス（生理） - いんぱるす

…(2) Muscle contraction Skeletal muscles come in various sizes and shapes depending on the location and function, but are made up of hundreds to thousands of muscle fibers with diameters of 10 to 100 μ. Muscle contraction (muscle contraction) occurs when nerve excitation (action potential or impulse) travels through the motor nerve fiber that controls that muscle fiber to the nerve terminal and is then transmitted to the muscle fiber. The junction between the nerve terminal and the muscle fiber has a special structure called the neuromuscular endplate, and when an impulse arrives, a transmitter substance called acetylcholine is released from the synaptic vesicles contained in the nerve terminal. …

From [Sensation]

…A sensory organ is a specially differentiated organ equipped with receptors. When a change in the internal or external environment is large enough, the receptor reacts, and then an action potential is generated in the afferent nerve fiber connected to it, which is called a nerve impulse or simply impulse. The impulse travels up the spinal cord or brain stem and reaches the sensory area of the cerebral cortex. …

…(2)筋肉の収縮　骨格筋は存在する部位や機能から種々の大きさ，形をしているが，数百～数千本の直径10～100μの筋繊維でできている。筋肉の収縮(筋収縮)は，その筋繊維を支配する運動神経繊維を通って神経の興奮(活動電位またはインパルス)が神経末端まで達し，さらに筋繊維に伝えられることにより生ずる。神経末端と筋繊維の接合部は神経筋終板と呼ばれる特殊の構造をしていて，インパルスが到着すると，神経末端部に含まれているシナプス小胞からアセチルコリンという伝達物質が放出される。…
