1. Inner Ear:
- Cochlea: Hair cells in the cochlea are responsible for hearing. They are located within the organ of Corti, a structure that runs along the length of the cochlea.
- Vestibular System: Hair cells in the vestibular system are responsible for balance and spatial orientation. They are located in the semicircular canals and the utricle and saccule.
2. Lateral Line System (in fish and some amphibians):
- The lateral line system is a sensory organ that allows fish and some amphibians to detect water movement and vibrations. Hair cells in the lateral line are located in structures called neuromasts, which are embedded in the skin.
It's important to note that while both locations are called "hair cells", the structure and function of hair cells in the inner ear and the lateral line system are slightly different.
