WebWhat has been described here is the action potential, which is presented as a graph of voltage over time in Figure 12.5.7. It is the electrical signal that nervous tissue generates for communication. The change in the membrane voltage from -70 mV at rest to +30 mV at the end of depolarization is a 100-mV change.

WebThe axon then branches through the muscle and connects to the individual muscle fibers at the neuromuscular junction. The folded sarcolemma of the muscle fiber that interacts with the neuron is called the motor end-plate; the folded sarcolemma increases surface area contact with receptors. WebThe axons of motor neurons begin to appear in the fourth week of development from the ventral region of the ventral-dorsal axis (the basal plate) also known as the motor neural progenitor domain (pMN). Transcription factors include Pax6, OLIG2, Nkx-6.1, and Nkx-6.2, which are regulated by sonic hedgehog (Shh). diy wood platform bed frame
