Eustachian tube in middle ear
12.2.3 POJA-L2608+2607+2609+2988
Title: Eustachian tube in middle ear
Description:
Generally the 1.5 cm osseus part (within the petrous part of the temporal bone) of the human eustachian tube has a simple
tunica mucosa with simple ciliary epithelium and a thin proper lamina closely attached to the bone periosteum.
In contrast, the longer pharyngeal cartilaginous part (2.5 cm) of the tube shows a nasopharyngeal mucosa with well-developed
proper lamina, seromucous tubal glands, nerve bundles and lymph nodules.
(A, C): Eustachian tube, immunoperoxidase staining with AEC and anti-neurofilament antibodies, postnatal rat.
Lumen (1) of the tube. In the proper lamina neurofilament-positive single nerve fibers are present (branches from the maxillary
nerve as principal sensory supply), located between small tubal glands (in A) and thin skeletal muscle fibers (in C).
(B): Eustachian tube, immunoperoxidase staining with AEC and antikeratin-14 antibodies (RCK107), postnatal rat.
Cytokeratin 14 stains strongly for the myoepithelial cells of the tubal glands (glandula tubaria).
(D): Eustachian tube, immunoperoxidase staining with AEC and antibodies against collagen IV, postnatal rat.
Staining for collagen IV is strong in capillary basement membranes as well as between individual nerve fibers in the bundle.
Keywords/Mesh: middle ear, eustachian tube, auditory tube, seromucous gland, myoepithelial cell, cytokeratin, neurofilament, collagen IV, histology, POJA collection
