MUSCLE PHYSIOLOGY

Detailed explanation-1: -Your inner ear has three main parts: your cochlea, semi-circular canals (labyrinth) and your vestibule. Your cochlea supports your hearing and your vestibule and semi-circular canals support your balance.

Detailed explanation-2: -The cochlea represents the ‘hearing’ part of the inner ear and is situated in the temporal bone. It derives its name from the Greek ‘kokhliās’ (meaning ‘snail’) as it forms a spiral structure during development, which makes it resemble a snail shell.

Detailed explanation-3: -Cochlea is the auditory organ present in the inner ear. Auditory receptors are present in the cochlea. It converts the auditory signals to neural impulses, which are carried by the afferent nerves fibres and auditory nerves to the brain, where it is integrated and we hear the sound.

Detailed explanation-4: -This action is passed onto the cochlea, a fluid-filled snail-like structure that contains the organ of Corti, the organ for hearing. It consists of tiny hair cells that line the cochlea. These cells translate vibrations into electrical impulses that are carried to the brain by sensory nerves.

Detailed explanation-5: -HUMAN COCHLEA-GROSS MORPHOLOGY. The two human cochleae are mirror-shaped, fluid-filled, coiled, fairly symmetrical bony tubes (3.2–4.2 cm long) situated in the petrous pyramids of the temporal bones. Perilymph; the fluid inside the scalae vestibuli and tympani communicates with the CSF via the cochlear aqueduct (Fig.
