Epidermal growth factor - a cytokine that stimulates epithelial cell proliferation. Epinephrine - a neurotransmitter substance found at all adrenergic synapses (nor epinephrine or epinephrine). It is
Fatty acids - long straight chains of carbon and hydrogen ending with an acid group at one end. Saturated fatty acids have no capacity to absorb more hydrogen atoms. Animal fats are mostly of this typ
Gangrene - the death of tissue on a large scale. May be caused by certain bacteria which spread rapidly through tissues, or by an inadequate blood supply. Ganglion - a collection of nerve cells usuall
Habitat - a location which has a suitable environment for an organism to live in. Caves are natural habitats for bats, trees for birds; oral surfaces and crevices, for some bacteria. Haemostasis - the
Inflammation - is a whole complex of events which occur in sequence, in response to injury. Tissue damaged by bacteria, chemicals, heat, trauma etc, release histamine and bradykinin and serotonin whic
Intermediate filaments - unlike microfilaments and microtubules, they are verystable. Instead of being stacked proteins, as in actin, intermediate filaments are built of interlocking proteins. A dense
Junctional epithelium - the epithelium which seals the base of the gingival sulcus against the tooth. Keratan sulphate - a glycosaminoglycan found in cartilage, with chondroitin sulphate. Keratin - a
Lamella-bone - the microscopic structure of cortical bone gives it the appearance of concentric or parallel plates ( from Latin, lamella, the diminutive of lamina, meaning a plate or leaf). Lamina pro
Macrophages - cells derived from monocytes which have the ability to phagocytose foreign particles and dead tissue and to move through tissue, or to remain fixed in one place. There are many macrophag
Ecological balance - astable balance in the numbers of each species in an ecosystem. In the ecosystem of the mouth this balance is brought about by competition and cooperation between the different or
Dermatan sulphate - a glycosaminoglycan found in skin, tendon, blood vessel and heart valves. Desmosomes -one of the types of cell junctions by which cells join or communicate with each other. Desmoso
Cemento-enamel junction- the junction between the enamel covering the crown of the tooth and the cementum covering its root. Often referred to as the CEJ. Cementoblasts - cells of mesenchyme origin, i
Calcium-binding proteins - proteins which have the ability to store calcium ions and to bind onto calcium in the hydroxyapatite of the enamel surface. Calculus - a hard deposit of calcified plaque whi
Apatites- a family of calcium phosphate salts which are found in hard tissues like bone, teeth and shells. Apoptosis - death of a cell which is programmed by a set of specific genes. Apoptosis of chon
Ameloblasts- cells which differentiate from ectoderm and secrete enamel during tooth development. Amino acids - building blocks of proteins containing a carboxyl group (COOH) and an amino group(NH2) b
Abductors - muscle taking a limb or the jaw away from the body. Acetyl choline - Aneurotransmitter substance found at all cholinergic synapses including those of motoneurones at the neuromuscular junc
Basal lamina - a term used to describe the different layers which make up the basement membrane. These different layers of the basement membrane, the lamina lucida and lamina densa are only visible wi
Microbiology - the study of the microscopic forms of life. Microfilaments - are the smallest filaments of the cytoskeleton. The filaments are made of hundreds of actin molecules, stacked in a line. Th
Morphogenesis - the process in which tissue shapes and organ structures are developed during embryology. Morphogenic fieled - an environment in which the shape or pattern of a developing organ is dete
