    bony labyrinth
  38. the bony labyrinth is composed of three parts which are
    semicircular canals, the vesibule, and the cochlea
  39. this part of the inner ear provides equilibrium sensations by detecting rotation, gravity, and acceleration.
    vestibular complex
  40. this portion of the vestibular complex consists of three semicircular canals which detects rotational movements of the head in three different planes
    semicircular ducts
  41. this specific portion of the vestibular complex consists of two chambers with receptors that are sensitive to head position relative to gravity and linear acceleration
    utricle and saccule
  42. the movement of the stapes at the oval window generates pressure waves that stimulate hair cells at specific locations alonf the length of this structure and is used in hearing*
    cochlear duct
  43. the hair cells of the utricle and saccule are clustered in oval structures called
  44. in regards to the eye located in the retina, these see colors of black and white, highly sensitive, they enable us to see in dimly lit rooms, at twilight and pale moonlight.
  45. this part of the retina provides us with color vision, giving us sharper, clearer images. but these require more light to see.
  46. this light sensitive pigment is found inthe rods
  47. this light sensitive pigment is found in the cones
  48. this kind of vision is less than 20 ft. away and the lenses can actually change and adjust
  49. the region of the ampulla within the ear that contains the receptors is known as the

    conjuctivitis aka pink eye
  68. the wall of the eye has three layers
    the fiberous, vascular, and inner

    vascular layer aka uvea
  72. this is the inner most layer of the eye where the light energy is collected
    inner layer or retina
  73. what are the 4 functions of the vascular layer
    blood vessel route, regulating light, regulating the aqueous humor, controlling lens shape (essential in focusing)
  74. the vascular layer is composed of three structures
    iris, ciliary body, and choroid
  75. this stucture gives eyes their color and control the pupil size
