glands that secrete mucus directly onto the apical surface of a lining epithelium.Multicellular Glands:most exocrine glands are multicellular, composed of many cellsthat form a distinctive microscopic structure or macroscopic organ. Examples includesudoriferous (sweat), sebaceous (oil), and salivary glands.Multicellular glands are categorized according to two criteria:(1) whether the ducts are branched or unbranched and(2) the shape of the secretory portions of the gland.If the duct does not branch, it is asimple gland.If the duct branches, it is acompoundgland.Glands with tubular secretory parts aretubular glands;those with roundedsecretory portions areacinar glands(alveolar glands).Tubuloacincar glandshave bothtubular and more rounded secretory parts.
*Page 119 for imagesA.Simple tubular:tubular secretory part is straight and attaches to a singleunbranched duct.B.Simple branched tubular:tubular secretory part is branched and attaches to asingle unbranched duct.
C.Simple coiled tubular:tubular secretory part is coiled and attached to a singleunbranched duct.D.Simple acinar:secretory portion is rounded, attaches to single unbranched duct.E.Simple branched acinar:rounded secretory part is branched and attached to asingle unbranched duct.F.Compound tubular:secretory portion is tubular and attaches to a branched duct.G.Compound acinar:secretory portion is rounded and attached to a branched duct.H.Compound tubuloacinar:secretory portion is both tubular and rounded andattaches to a branched duct.6.describe the general components of connective tissue: cells, ground substance and fibers..
