Answer:
The term “reptile” is derived (Made) from a Latin word meaning “creeping animals.” These animals include snakes, lizards, crocodiles, alligators, turtles, geckos, and chameleons, with lizards and snakes species making up the majority of all reptiles. Reptiles are cold-blooded animals which means they are unable to regulate their own body temperature. Reptiles are Oviparous (Egg laying). Reptiles also have chains of bony elements from the tail to the head. The bony endoskeleton consists of cranium or skull, appendages, and limb girdles. The endoskeleton protects the inner tissue and also aids in body movement. Skeletons differ from one species to another, with crocodiles having some of the largest body structures in this class.
Explanation: It was actually quite fun writing this
Shallow groove on the surface of the cortex is called sulcus.
Cortex means the outer layer of an inner organ. The outer layer of the cerebrum is called cerebral cortex, where cerebrum occupies the biggest part of the brain. A human being has four lobes of the cerebral cortex which include temporal lobe, parietal lobe, occipital lobe, and frontal lobe.
Cortex has six layers of different types of neurons which are responsible for higher information processing and thinking. Cerebral cortex controls general movement, behavioural reactions, perception and visceral functions. We term the grooved layer as the brain itself.Cerebral cortex consists of large amounts of sulci and gyri(sulcus and gyri in singular). The number of gyri correlates to the processing ability of the animal.A man has big gyri compared to a rat.
