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.
All B vitamins can be found in animal products, as well as some fortified foods, so vegetarians might not get enough of each vitamin. If you're at risk of a deficiency, pay closer attention to the foods you eat to be sure you're consuming the right amount of all the B vitamins.t can be found in eggs and dairy products as well as fortified cereals and soy milk. The main concern is for vegetarians who do not eat eggs and dairy, as they are not able to get enough vitamin B-12 from other sources.
