endolymphatic duct

An endolymphatic duct runs from the saccule up through the head, and ending close to the brain.

The endolymphatic duct is wrapped in a simple loop around the lagena, with the basilar membrane lying along one side.

In some cases, the endolymphatic duct may be obstructed by scar tissue, or may be narrow from birth.

This duct connects the utricle with the endolymphatic duct a short distance from the saccule.

Böttcher's space: Also known as the endolymphatic sac; the blind pouch at the end of the endolymphatic duct.

The presence of these extrinsic grains, in osteostracans, chondrichthyans, and acanthodians indicates a common inner ear physiology and presence of open endolymphatic ducts.

(6) Dermal bone with cells, epicercal tail with modified scale cover (hinge line), paired pectoral fins, open endolymphatic duct, sclerotic ossification.

An endolymphatic sac tumor is a very uncommon papillary epithelial neoplasm arising within the endolymphatic sac or endolymphatic duct.

Studies suggest that the endolymphatic duct and endolymphatic sac perform both absorptive and secretory, as well as phagocytic and immunodefensive,functions.

An enlarged endolymphatic duct and sac and a deficient utriculoendolymphatic valve are commonly found associated with collapse of Reissner's membrane or an absence of endolymphatic hydrops.

Running through it is a tube called the endolymphatic duct, which normally carries a fluid called endolymph from the inner ear to the endolymphatic sac in the cranial cavity.

When the endolymphatic duct and sac are larger than normal, as is the case in large vestibular aqueduct syndrome, endolymph is allowed to travel back from the endolympathic sac into the inner ear.

The semicircular canals and sacs in all vertebrates are attached to endolymphatic ducts, which in some groups (such as sharks) end in small openings, called endolymphatic pores, on the dorsal surface of the head.
