To properly answer the question of how long do eggs last, how long are eggs good for, or the shelf life of eggs, a variety of factors must be examined such as the sell by date and how the eggs have been stored.
  The initial region of the axon arises from a cone-shaped area of the cell body called the axon hillock (little hill).4 people found this useful.ETWEEN NEURONS: A neural signal can be passed from one neuron to another, at a synapse, across the synaptic cleft, by the release of chemicals called neurotransmitters from the presynaptic neuron, which diffuse across the synaptic cleft, to fit into receptors on the postsynaptic neuron.
Axons are extended regions of the neuron cell membrane. It starts from a portion of the cell body, known as the axon hillock. From there, the axon extends towards the target cell to what is known as the terminal. Along the cell membrane of the axon will be ion channels and ATP-driven pumps that will regulate ion concentrations within the axon.
