Oogenesis consists of three stages known as the multiplication phase, growth phase, and matura…. WebSynapses between neurons are either excitatory or inhibitory – and that all comes down to the neurotransmitter released. Excitatory neurotransmitters cause the signal to propagate - more action potentials are triggered. Inhibitory signals work to cancel the signal.

WebSynapses. An electrical nerve impulse travels along the first axon. When the nerve impulse reaches the dendrites at the end of the axon, chemical messengers called … Web2 days ago · A synapse is a junction between the nerve cell and its target tissue. In humans, synapses are chemical, meaning that the nerve impulse is transmitted from the axon ending to the target tissue by the chemical … WebThis is where the electrical message is changed to a chemical signal using neurotransmitters to communicate with the next group of nerve cells, muscle cells or organs. Neurotransmitters are located in a part of the neuron called the axon terminal. They’re stored within thin-walled sacs called synaptic vesicles. fly from mia to gye
