Glandular Epithelium Tissues

1. Exocrine glands

   • Unicellular glands
     • Single -celles glands Such as goblet cells,interspersed— columnar ep Tissues
   • Multicellular glands
     • Simple
       • Do not branch
     • Compound
       • Branch
     • Acinar glands
       • Like flask
       • Tubulo-
     • Merocrine glands
       • Secrete a watery substance through cell membrane
         • Salivary, pancreatic and certain sweat glands
     • Apocrine glands
       • A portion of cell & The secretion discharged
         • Secretion accumulate on the surface
         • Mammary glands
     • Holocrine glands
       • Entire cell & its product discharged
         • Oil-secreting (sebaceous) glands
     • Tubular
       • Like tubes
       • acinar
