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.
Liver, clams and trout are all especially rich in vitamin B-12. Because animal products are the most common sources of vitamin B-12, vegans may be a risk for deficiency.Eating fortified foods or nutritional yeast, or taking dietary supplements, may reduce this risk.ot eating enough foods rich in B vitamins may lead to deficiency. Because different B vitamins take on different roles in your body, symptoms of deficiency may vary depending on which vitamin you are lacking.
