Ответ:

Вегетативные нервные волокна менее возбудимы, чем соматические, и обладают более длительным рефрактерным периодом, большей хронаксией и меньшей лабильностью.

Поэтому для их возбуждения необходимо более сильное раздражение, чем для соматических волокон. Соматические нервные волокна миелинизированы (относятся к типу А). Отсюда и различная скорость проведения нервных импульсов.

Ответ:

1)В вегетативном отделе нервной системы тело эффекторного нейрона находится за пределами головного или же спинного мозга, в то время как в соматическом отделе нервной системы вставочная и двигательная нервные клетки находятся внутри серого вещества спинного мозга.

2)В то время как соматическая нервная система находится под вашим сознательным контролем, ни одна из вегетативных нервных систем не является.

The Himalayas have been the scene of many rivalries over the years. Few, however, have been as long or heroic as the battle between Jerzy Kukuczka and Reinhold Messner during the early 1980s. Both men were trying to be the first to reach all 14 peaks in the world which are over 8,000 metres. Messner completed this remarkable achievement a year earlier than Kukuczka. However, it took Messner 16 years to do it, whereas the Polish climber did it in only 8 years. Kukuczka, who was born in Katowice, Poland, in 1948, was a brilliant mountaineer. While trying to reach the 14 highest summits, he established nine new routes, reached one summit by himself, and did four of them in winter. In fact, many consider his achievement to be greater than Messner's, especially considering that his equipment was often hand-made and his clothes second-hand. Unfortunately, Kukuczka died attempting to reach the top of Lhotse in 1989. He was buried by his friends in a Himalayan glacier.
Messner, on the other hand, is a living legend among climbers. Born in South Tyrol(Italy) in 1944, he is one of the world's most successful and famous mountaineers. He was the first person to climb Mount Everest alone without oxygen, and he has also crossed Antarctica on skis. But Messner's career has had its tragic moments too. During his first major Himalaya climb in 1970, both he and his brother, Gunther Messner, reached the summit. However, Gunther died two days later on the way down the mountain. Messner, who is now a wealthy man, has no intention of settling down in his castle in the Italian Alps. He keeps on exploring, climbing, writing and having new adventures in 2004 he walked 2000 kilometres through the Gobi desert. Curiously, Messner is one of the few western people that claim to have seen the Yeti. He says he has met it twice, and has photographic evidence to prove it! However, in his book about the Yeti there is no real proof. Instead he just speculates that the Yeti is a large, long haired bear.
