Functions: Both mechanical and chemical digestion begin in the mouth. The tongue and teeth mechanically break food into smaller pieces through process of mastication, salivary enzymes in the saliva begin the process of chemical digestion. Pharynx (throat): A Muscular tube which connects the post...
It is generally agreed that the enamel cap is a crucial element in controlling the mechanical behavior of mammalian teeth under load. Incisors are particularly interesting in terms of structure鈥揻unction relations, as their role in feeding is that of the 'first bite'. However, little is known...
Describe the types of teeth and their functions. Identify the structure from the given description: Passes swallowed food to the stomach. What structure of the eye modifies the shape of the lens? (a) Define salivary glands. (b) What is its function?
The dental pulp is a richly innervated and vascularized, loose connective tissue. As previously mentioned, the study of the dental pulp cannot be disassociated from that of dentine, since one of the principal functions of the pulpal tissue is, in fact, t
teeth, formingdental plaque; however, the genes that control the production of the slime layer are only expressed in the presence of sucrose (table sugar). Thus, while the genotype ofS. mutansis constant, its phenotype changes depending on the presence and absence of sugar in its environment....
One of the simplest ways to understand the structures and functions of theorganelleshoused within a cell – and cell biology as a whole – is to compare them with real world things. For example, it makes sense to describe theGolgi apparatusas a packing plant or post office because its role...
Infibrous joints, the two bones are connected by dense regular connective tissue. The best example of this type is the sutures of the skull and the teeth insertion into the jaw. Cartilaginous In acartilaginous joint, cartilage spans the gap between the two bones. Within this category, it can...
Biological invasions are a major threat to biodiversity and have particularly devastating impacts on island ecosystems. The New Caledonia archipelago is co
As you grow older, the functions of your essential organs begin to deteriorate. All of the body's cells, tissues, and organs are affected by ageing, and these changes directly impact the functioning of the entire body. There are a lot of cells in a ...
According Durkheim, what is the function of the division of labor in modern, complex societies and what distinguishes the normal form of the division of labor from its abnormal forms? What are three different types of cofactors and their functions?
