Spines primarily have a protective function in plants. The spines can be sharp, and form a physical barrier against herbivores which may want to feed on the plant. Spines however also have other benefits. The spines on a jumping cactus allow segments of the cactus to stick to passing large animals or humans, thereby allowing the cactus to spread to other areas through asexual propagation. Spines are modified leaves, and spines have a much lower surface area than leaves, and therefore can reduce transpirative loss of water by the plant during harsh droughts. Some trees in alpine regions, such as pine trees, have developed spine-like leaves to prevent the accumulation of snow in the branches.
It main aim to give an overview about the effect of dietary nutrients on the structure and functions of brain. Brain which is elaborated from substances present in the diet such as vitamins, essential amino acids, fatty acids, omega-3 , etc.
Micronutients ( vitamins, trace- elements) have been directly evaluated in the setting of cerebral functioning. Nervous tissues use glucose to produces the energy and implies the presence of vitamin B1 , which perform cogitative functions, specifically in elderly. Vitamin B9 , which preserve the brain during its development .
Genetic potential of children for their physical growth and mental development may compromised due to deficiency of micronutrients. Their poor nutritional status are exposed to alterations of mental and behavioral functions that can corrected by dietary measure.
