BRAIN snake is very similar to bird brains, snakes have no shortage of cerebral hemispheres, unlike birds and mammals. One can say that snakes are not very intelligent creatures, but they can learn when the feeding time, and we will often find that at feeding time waiting for the owner. She felt the snake based on smell and touch, and thermal sensors on the head, by which detect prey. Have no movable eyelids, but they have called. clear membrane that protects the eye. Because of that snake eye movements are limited. They have no external or middle ear or eardrum. They have called. small ear bones using that detect vibrations from the environment, through the country. The vibrations from the air is very difficult to detect, and only those very low frequencies. Snakes have two nostrils, but unlike mammals, they can not serve as the sense of smell. Instead we use the rapid movements of language as a sensory apparatus of smell. Possessing a tiny organ in the upper side of the mouth called the Jacobsons organ, which through the tongue receives small particles from the environment and thus detects the scent of prey or predators. Unlike mammals, their language does not serve as the sense of taste, but solely as the sense of smell. Snakes have, unlike mammals, the so-called. sixth sense, or heat detectors. Heat detectors are located between the nasal cavity and eyes. Using these sensors, see snakes warm-blooded animals, and prey, as infrared radiation. These thermal sensors have two chambers, foreign and domestic. Internal detects body heat the snakes (cold-blooded animals - body temperature depends on ambient temperature), and the outer for detecting prey and observed heat distinct from that of a registered interior cell. These sensors are sensitive to the family Viperidae snakes, and even detect the heat difference of 0.002 degrees Celsius. The skin of a snake in direct contact with the ground, and because of their specific structure protects the snake from attrition, injuries and dehydration. The skin is made up of "shells" that are on the sides and upper body smaller, thinner and less, and in the lower part of the body, which is in contact with the ground, thicker and thicker. The skin is dry and has two glands, even anal glands whose secretions serve to attract the opposite sex, protection from predators and to mark territory.
