Document Summary
Treatment- lancing (cutting) furuncle to drain: sebaceous glands and follicles are sensitive to hormone changes, secretory activity accelerates at puberty. Thus, individuals with large sebaceous glands may be especially prone to acne. Acne: blockage and inflammation of ducts of large sebaceous glands: seborrheic dermatitis: inflammation around abnormally active sebaceous glands. Dandruff: mild case in adults: sweat (sudoriferous) glands (fig 4. 14): simple cuboidal glandular glands that contain myoepithelial cells and produce watery solution, myoepithelial cells: specialized epithelial cells that contract and squeeze gland causing discharge of accumulated secretions. Secretory activity controlled by autonomic nervous system and circulating hormones: 2 types: merocrine and apocrine. Merocrine (eccrine) sweat glands: simple, coiled, tubular sweat glands that open directly onto the surface of the skin through sweat pores. Mainly in palms of hands and soles of feet (can be activated by emotional stress) More numerous, more widely distributed and smaller that apocrine glands and do not extend as far into the dermis.
