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.
The first 50 to100 |lm of the axon, after it emerges from the axon hillock, is known as the initial segment (Fig. 5-1A). The action potential originates at the axon hillock. An action potential is a brief fluctuation in the membrane potential, which moves like a wave along the axon in order to transfer information from one neuron to another.
