Culture that is identifiably Etruscan developed in Italy after about 800 BC approximately over the range of the preceding Iron Age Villanovan culture. The latter gave way in the 7th century to a culture that was influenced by Hellenic, Magna Graecian, and Phoenician contacts.he Etruscans, like the contemporary cultures of Ancient Greece and Ancient Rome, had a significant military tradition. In addition to marking the rank and power of certain individuals in Etruscan culture, warfare was a considerable economic advantage to Etruscan civilization.
Axons usually have thousands of terminal branches that each end as a bulbous enlargement called a synaptic knob or synaptic terminal. Synaptic knobs contain several membrane-bounded synaptic vesicles that are 40 to 100 nanometers in diameter.
Synaptic cleft is the space between the motor end plate (muscle fiber part) and synaptic end bulb (motor neuron part) of the neuromuscular junction. It is 20 to 30 nanometers wide. Because of this cleft, the connection between the motor neuron and the muscle fiber is not continuous and there is a break.ifference between synapse and neuromuscular junction: Synapses and neuromuscular junctions are physiologically the same, however, the neuromuscular junction is a specific type of synapse that occurs between motor neuron and muscle fiber.
