Final answer:
The receptors for hearing and equilibrium are located in the inner ear, specifically in the cochlea for hearing and the vestibule and semicircular canals for equilibrium.
Step-by-step explanation:
The receptors for hearing and equilibrium are located in the inner ear. The cochlea in the inner ear is responsible for hearing, while the vestibule and semicircular canals in the inner ear are responsible for equilibrium. These structures contain the sensory receptor cells (hair cells) that transduce sound waves into neural signals for hearing and detect head position and movement for equilibrium.
