Each neuron consists of a cell body or perikaryon, from which arise the nerve fibers. And each neuron has two kinds of fibers: a single axon, which conveys nerve impulses away from the cell body, and one or more dendrites, which convey nerve impulses towards the cell body. Neurons are functionally linked by their fibers at connections called synapses. All neurons are post-mitotic.
However, unbalanced vegetarian diets may be lacking in a number of important nutrients. To ensure that you are eating a balanced vegetarian diet, you should regularly consume sources of vitamin B-12, iron, zinc, omega-3 fatty acids and essential amino acids.
Q. I currently follow a strict vegetarian diet and consume no animal products at all. Since vitamin B12 is missing from the vegan diet, I wonder how many micrograms of it I should take.Iâve seen B12 pills of up to 1500 micrograms each in my food co-op, but the daily requirement is just 3 micrograms.A. Vitamin B12 deficiency is far more common than most people realize.Vegans (who eat no eggs, dairy or other animal products) are frequently lacking in this essential nutrient. Older people and those who take powerful acid-suppressing drugs may also be low.. Vitamin B12 deficiency is far more common than most people realize.
