Mucous glands

Mucous glands - exocrine glands secreting liquid secret that wets the mucous membranes, protecting them from drying out, mechanical and chemical influences. The secret of mucous glands adsorbs dust particles, microorganisms and some digestive enzymes. The structure and the form of mucous gland is divided into unicellular and multicellular. The first lie in the thickness of the epithelium and presents goblet cells, and the latter are located in the connective tissue beneath the epithelium and are simple or complex tubular or alveolar-tubular glands. Multicellular glands consist of secreting end of departments and ductless. All mucous glands produce the secret to mararikulam type (see Gland). Pathology mucous glands usually caused by blockage of the excretory ducts (for example, retention cysts of the mucous membrane of the esophagus, mucous cysts of the cervix), and with the emergence of various tumors.
