Lymph nodes often swell in one location when a problem such as an injury, infection, or tumor develops in or near the lymph node. Which lymph nodes are swollen can help identify the problem. 1  The glands on either side of the neck, under the jaw, or behind the ears commonly swell when you have a cold or sore throat.ymph nodes often swell in one location when a problem such as an injury, infection, or tumor develops in or near the lymph node.

keratinocyte. [keratâ²inÅsÄ«tâ²]. Etymology: Gk, keras + kytos, cell. an epidermal cell that synthesizes keratin and other proteins and sterols. These cells constitute 95% of the epidermis, being formed from undifferentiated, or basal, cells at the dermal-epidermal junction.tymology: Gk, keras + kytos, cell. an epidermal cell that synthesizes keratin and other proteins and sterols.

Keratinocytes = cells of the skin producing keratin; so called prickle or MALPIGHIAN cells. Stratum basale = basal layer. is, together with the stratum spinosum, responsible for cell reproduction in this layer; this layer consists of tall cylindrical cells (Epitheliocytus basalis) and melanocytes.tratum spinosum = prickle cell layer. is multi-layered and consists of polygon-shaped cells joined together by desmosomes (visible in the electron microscope as thickening of the cell membrane). In this layer the keratinocytes are joined by tonofibrils (a filament of proteins) like a network.
