Reptilian Anatomy

Ectothermiareliance on environmental heat and behavior to maintain a preferred body temperature pbt. Those better skeletons paid off.

Reptile Anatomy And History

Most typical sense organs are well developed with certain exceptions most notably the snakes lack of external ears middle and inner ears are present.

Reptilian anatomy. Reproductive physiology in the female lizard is broadly similar to that of the avian patient. The shell normally consists of bony plates overlaid with horny shields. The reptilian nervous system contains the same basic part of the amphibian brain but the reptile cerebrum and cerebellum are slightly larger.

Physiological adaptations of the reptilian brain reptiles are ectotherms and must behaviorally or physiologically adapt to varying temperatures making reptile brains notable for their adaptation to extreme conditions. Some species such as some of the chameleonidae are ovoviviparous. As with other traits reptiles took it to the next level.

It is true that fish and amphibians have skeletons. Pbt is the core temperature at which a metabolic process is optimal. Except snake most of the reptiles have four limbs.

The structure of the reptile body has been designed to make it comfortable in both habitats. The female lizard has much the same anatomy as that described for the snake. Pbt varies with species age season and even time of day.

The regeneration of the tail in reptiles differs from that of amphibians and fishes in that it happens without the formation of a blastema and instead of an actual regeneration of the caudal vertebras it forms a cartilaginous tube along it. The new tail is stiffer and shorter than the original one. The turtlesturtle a reptile of the order chelonia with strong beaked toothless jaws and usually an armorlike shell.

Reptiles are skilled to live on both land and in water. Order chelonia have a protective bony shell usually covered with horny plates. Creatures such as mammals developed more complicated brain structures on the foundation of the reptilian brain allowing for thought emotion and self awareness.

They have their habitat very close to the ground. According to the triune brain theory the reptilian brain concerned with instinct and survival developed first in evolutionary history. They developed larger skeletons that could hold larger organs and help them increase in size.

Some of the biggest creatures to ever walk on the planet have been the dinosaurs. The reptilian brain according to a classic theory of brain science has corresponding structures in the brains of mammals including humans.
