@amhbhaiofficial: Endocrine Glands Origin Endocrine glands originate from epithelial tissue during embryonic development. They develop as epithelial cells that grow inward from body surfaces or from epithelial buds, then lose their ducts and become ductless glands that release hormones directly into the bloodstream. Key point: Most endocrine glands are epithelial in origin and become ductless as they mature.#EndocrineSystem #Endocrinology #EndocrineGlands #Hormones #MedicalEmbryology #Histology #MBBSNotes #NursingNotes #Physiology #HealthEducation
