- secondary palate foramation The secondary palate is a partition which develops in some species of amniotes to separate the nasal passages from the oral cavity. In fishes, amphibians, most reptiles, and all birds, the nasal passages are short and connect with the oral cavity near the front of the mouth.

Definition of Tongue The tongue is a muscular hydrostat on the floor of the mouth of most vertebrates that manipulates food for mastication. It is the primary organ of taste (gustation), as much of its upper surface is covered in taste buds.The tongue's upper surface is also covered in numerous lingual papillae.It is sensitive and kept moist by saliva, and is richly supplied with nerves and blood vessels. In humans a secondary function of the tongue is phonetic articulation.he tongue's upper surface is also covered in numerous lingual papillae.

Structure and Function of the Tongue, Teeth and Mouth in Dogs 1 On the sides and front of the mouth, the teeth and lips form the major boundary. On the bottom, the tongue and adjacent tissues form the floor of the mouth.  The tongue is an elongated muscular organ with the top surface covered with specialized little mushroom-shaped structures called papillae.

Tooth A chimpanzee displaying its teeth. A tooth (plural teeth) is a hard, calcified structure found in the jaws (or mouths) of many vertebrates and used to break down food. Some animals, particularly carnivores, also use teeth for hunting or for defensive purposes. The roots of teeth are covered by gums.

Mandible In lobe-finned fishes and the early fossil tetrapods, the bone homologous to the mandible of mammals is merely the largest of several bones in the lower jaw. In such animals, it is referred to as the dentary bone, and forms the body of the outer surface of the jaw. It is bordered below by a number of splenial bones, while the angle of the jaw is formed by a lower angular bone and a suprangular bone just above it.

Palate It separates the oral cavity from the nasal cavity. A similar structure is found in crocodilians, but, in most other tetrapods, the oral and nasal cavities are not truly separate. The palate is divided into two parts, the anterior bony hard palate, and the posterior fleshy soft palate (or velum).

The surface area of the adult human mouth and thickness of the salivary film covering the teeth and oral mucosa. Collins LM, Dawes C. The surface area of the mouth was measured to calculate the average thickness of the salivary film which separates the opposing layers of the oral mucosa and which also overlies the dental plaque. The subjects were 10 adults of each sex, all of whom had essentially a full complement of teeth.

THE RESPIRATION PROCESS The place where this exchange of gases occurs is called the respiratory surface (lungs in mammals, gills in fish, skin in earthworm, cell surface in Amoeba). Fill in the table below to explain why respiratory surfaces usually share some basic design features. You will probably find it worthwhile to refer to diffusion.

Skin Skin is the soft outer covering of vertebrates. Other animal coverings such as the arthropod exoskeleton have different developmental origin, structure and chemical composition. The adjective cutaneous means of the skin (from Latin cutis, skin).kin of a different nature exists in amphibians, reptiles, and birds. All mammals have some hair on their skin, even marine mammals which appear to be hairless. The skin interfaces with the environment and is the first line of defense from external factors.
