Exterior of labyrinth of the inner ear. Benign paroxysmal positional vertigo ( BPPV) is a disorder arising from a problem in the inner ear. [ 3] Symptoms are repeated, brief periods of vertigo with movement, characterized by a spinning sensation upon changes in the position of the head. [ 1] This can occur with turning in bed or changing ...
Anatomical terminology. [ edit on Wikidata] Diagram of a typical long bone showing both cortical (compact) and cancellous (spongy) bone. Haversian canals[ i] (sometimes canals of Havers, osteonic canals or central canals) are a series of microscopic tubes in the outermost region of bone called cortical bone. They allow blood vessels and nerves ...
53401. Anatomical terms of neuroanatomy. [ edit on Wikidata] The vestibular nerve is one of the two branches of the vestibulocochlear nerve (the cochlear nerve being the other). In humans the vestibular nerve transmits sensory information from vestibular hair cells located in the two otolith organs (the utricle and the saccule) and the three ...
Human ear. The semicircular canals are three semicircular interconnected tubes located in the innermost part of each ear, the inner ear. The three canals are the lateral, anterior and posterior semicircular canals. They are the part of the bony labyrinth, a periosteum -lined cavity on the petrous part of the temporal bone filled with perilymph .
The vestibular system, in vertebrates, is a sensory system that creates the sense of balance and spatial orientation for the purpose of coordinating movement with balance. Together with the cochlea, a part of the auditory system, it constitutes the labyrinth of the inner ear in most mammals . As movements consist of rotations and translations ...
Vestibular aqueduct. Interior of right osseous labyrinth. The cochlea and vestibule, viewed from above. (Aquaeductus vestibuli labeled at bottom right.) At the posterior lateral wall of the temporal bone is the vestibular aqueduct, which extends to the posterior surface of the petrous portion of the temporal bone. [ 1]
The utricle and saccule are the two otolith organs in the vertebrate inner ear. The word utricle comes from Latin uter 'leather bag'. The utricle and saccule are part of the balancing system ( membranous labyrinth) in the vestibule of the bony labyrinth (small oval chamber). [ 1] They use small stones and a viscous fluid to stimulate hair cells ...
Its lateral edge corresponds with the remains of the petrosquamous suture. [1] The Atticus is the part of the tegmentum tympani where the stapes and incus are attached. The floor of the cavity (also called the jugular wall) is narrow, and consists of a thin plate of bone (fundus tympani) which separates the tympanic cavity from the jugular ...
