Compare electrical and chemical synapses. Describe the steps of how cross-bridge muscle contractions take place using the following general information: 1) Action potential (generated by motor neuron) innervates
A neuron is the structural unit of the nervous system. It has the ability to conduct both electrical and chemical impulses throughout the body in order to control voluntary and involuntary actions. The exchange of signals between neurons is accomplished by the presence of special structures called...
Synapse Synapse is a specialized intercellular site where fast, highly localized transmission of chemical and electrical signals can occur. Although the vast majority of synapses in the mammalian brain are chemical, synaptic transmission can be chemical or electrical. At chemical synapses, neurotransmitter...
Compare and contrast the innate arms of the immune system, addressing the cells involved, mechanisms of mediating immunity, timing of action and location. State True or False: B cells enter the lymph node by extravasation through HEV. Compare electrical and chemical synapses. The best way to r...
electrical pulse, which has been facilitated by created voltage gradients through intracellular and extracellular ion pumps of sodium, potassium, calcium, and chloride. The signal is passed from one neuron to the other via chemical signalling synapses. Neural networks connect neurons with each other ...
