The bony labyrinth is a region of dense bone that surrounds and protects the membranous labyrinth.
Labyrinth is the name given to the inner ear. It is made up of a network of interconnecting sacs and canals. The inner ear is composed of two parts: bony labyrinth and membranous labyrinth. A vestibule, three semicircular canals, and a spirally wound cochlea make up the bony labyrinth. It is perilymph-filled.
The membranous labyrinth is encircled by the bony labyrinth. It includes the hearing and balance sensory receptors. The cochlear duct, saccule, and utricle and three semicircular ducts that make up the endolymph-filled membranous labyrinth. The cristae, an organ of corti, and the ampullaris maculae are examples of sensory receptors.
