Identify the location and function of the following structures:
$(1)$ Cone cells
$(2)$ Ear ossicles
$(1)$ Cone cells
$(2)$ Ear ossicles
(N/A) $(1)$ Location: Present in the retina of the eye,specifically in the fovea region.
Function: Responsible for high-acuity vision,sensing bright light,and color vision.
$(2)$ Location: Located in the middle ear cavity.
Function: These three small bones (malleus,incus,and stapes) act as a mechanical lever system to amplify and transmit sound vibrations from the tympanic membrane to the oval window of the inner ear.
