What is the jawbone of a mammal?
Mammals have a single lower jawbone that attaches directly to the skull. The dentary bone holds the teeth of the lower jaw in place. Other species of vertebrates have more than one bone in the lower jaw that and not attached directly to the skull. The dentary lower jawbone articulates with the squamosal bone of the upper jaw. The two jaws are connected to the skull by muscles through a coronoid process that aids in chewing. The joint allows mammals to move the jaw easily and chew effectively with less energy spent in the process.
What are the two types of vertebrates?
This is a trait found but not limited to mammals. Reptiles, amphibians, fish, and birds are also vertebrates. Vertebrates have an endoskeleton that allows for the attachment of muscles, flesh, and ligaments. The endoskeleton also protects the vital organs of mammals such as the heart, kidneys, and lungs.
Why do mammals have hair?
Mammalian hair assumes different forms including whiskers, thick fur, and quills. Hair is vital to mammals because it protects the delicate skin from external damage and it also offers camouflage and acts as sensory receptors. Hair is also essential in metabolism and temperature regulation because it allows the body to preserve or release heat. Aquatic mammals such as dolphins and whales have hair during the early stages of development, some of these animals retain patches of hair on the upper lips and in the chins while some do not.
Which condyle allows mammals to hold their head in place?
The two knobs fit into the bones of the neck. The occipital condyles allow mammals to hold the heavy skulls in place and move the head sideways without breaking their neck. Other species of animals such as reptiles and fish have a single occipital condyle that limits the movement of the heads.
Do mammals give birth to their young?
Mammals generally give birth to living young ones except for the two species of monotremes, which are the echidna, and the duck-billed platypus. After giving birth, mammals nurse their young ones with milk secreted by the mammary glands. Mammary glands are present in both male and female in most mammalian species, but they are more developed in females. The rule is, however, an exception in the male Dayak fruit bat, which is a mammalian male that produces milk. Mammals take care of the young ones after giving birth until they are old enough to take care of themselves. Even though monotremes lay eggs, they have mammary glands that produce milk for the young ones after they hatch.

Why do mammals have fur?
Another reason mammals have hair or fur is that they are warm blooded. They can maintain their body temperature and achieve homeostasis without the help of the surrounding environment, unlike cold-blooded animals . Their hair or fur coverings help to keep them warm, and hair follicles can regulate blood temperature during piloerection.
