    help move eyeball

    Extrinsic Eye Muscles

  • 25

    -sense of smell - occurs in response to odorants - receptors are located in nasal cavity and hard palate - we can detected 10,000 different smells

    Olfaction

  • 26

    -detect taste -located on papillae on tongue, hard palate, throat

    taste buds

  • 27

    firm, white outer part - helps maintain eye shape, provides attachment sites, protects internal structures

    sclera

  • 28

    - transparent structure that covers iris and pupil - allows light to enter and focuses light

    cornea

  • 29

    contains blood supply

    middle tunic

  • 30
