The human ear has evolved with two basic tools to encode sound waves; each is separate in detecting high and low-frequency sounds. Georg von Békésy (1899–1972) employed the use of a microscope in order to examine the basilar membrane located within the inner-ear of cadavers.
The bony labyrinth (also osseous labyrinth or otic capsule) is the rigid, bony outer wall of the inner ear in the temporal bone. It consists of three parts: the vestibule, semicircular canals, and cochlea. These are cavities hollowed out of the substance of the bone, and lined by periosteum.
In Greek mythology, the Minotaur [b] (Ancient Greek: Μινώταυρος, Mīnṓtauros), also known as Asterion, is a mythical creature portrayed during classical antiquity with the head and tail of a bull and the body of a man [4] (p 34) or, as described by Roman poet Ovid, a being "part man and part bull".
Human vestibular system of the semicircular canals in the inner ear. 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.
How sounds make their way from the source to the human brain. In vertebrates, an ear is the organ that enables hearing and (in mammals) body balance using the vestibular system. In humans, the ear is described as having three parts: the outer ear, the middle ear and the inner ear. The outer ear consists of the auricle and the ear canal.
Endolymph is the fluid contained in the membranous labyrinth of the inner ear. The major cation in endolymph is potassium, with the values of sodium and potassium concentration in the endolymph being 0.91 mM and 154 mM, respectively. [1] It is also called Scarpa's fluid, after Antonio Scarpa. [2]
The membranous labyrinth is a collection of fluid filled tubes and chambers which contain the receptors for the senses of equilibrium and hearing. It is lodged within the bony labyrinth in the inner ear and has the same general form; it is, however, considerably smaller and is partly separated from the bony walls by a quantity of fluid, the perilymph.
Bones are commonly described with the terms head, neck, shaft, body and base. The head of a bone usually refers to the distal end of the bone. The shaft refers to the elongated sections of long bone, and the neck the segment between the head and shaft (or body).
