Seborrheic dermatitis (Fig. 1) is a common chronic, superficial inflammatory disease of the scalp, face (especially the eyebrows and nasolabial folds), ears, and central chest, affecting 2% to 5% of the population. Clinically, the disease is characterized by thin erythematous plaques, often with a fine, greasy scale.eborrheic dermatitis (Fig. 1) is a common chronic, superficial inflammatory disease of the scalp, face (especially the eyebrows and nasolabial folds), ears, and central chest, affecting 2% to 5% of the population.

the function of dendrons is that the dendron has dendrite on the end which receive impulses from receptor cells or other neurones which are then moved along the dendron to the axon.
What are Dendritic Cells? Dendritic cells are a type of antigen-presenting cell (APC) that form an important role in the adaptive immune system. The main function of dendritic cells is to present antigens and the cells are therefore sometimes referred to as âprofessionalâ APCs. In addition, only the dendritic cells have the capacity to induce a primary immune response in the inactive or resting naÃ¯ve T lymphocytes.
