Neuro Transmission Positive Charge
488 wordsneurotransmitters play a central and critical role in our psychological existence, identity, and experience of the world Neurotransmitters are chemicals that communicate between nerves. In some ways, neurons are like computers: they receive messages, process those messages, and send out the results as new messages to other cells. In the case of neurons, messages consist of chemicals that interact with the outer surface of the cell membrane. This chemical interaction with the cell membrane causes...

Amp Amp Neuromuscular Junction
1,706 words... e effects would lead to a decrease in the safety factor for neuromuscular transmission. The safety factor is the difference between the threshold needed to elicit an action potential, which is usually around - 45 mV and the actual end-plate potential amplitude, which is usually 70 - 80 mV, this is shown in figure 5. As a result of the reduced number of functional A ChR, the skeletal muscle becomes weakened. This weakness has four special characteristics: 1. It generally affects the cranial m...

Peripheral Nervous System Central Nervous System
431 wordsThe Nerves System Nervous System The two types of the nervous system are the Central nervous system and the peripheral nervous system. They are responsible for integrating, processing, and coordinating Sensory data and motor commands the central nervous system, which interprets sensory input and carry information to maintain homeostasis. CNS can t be regenerate because a CNS consists of the spinal cord that mean if it s break the spinal cord is break also. The peripheral nervous system consists ...
