Using the Eye Model, Identify:
1.  Lacrimal apparatus = lacrimal gland 🡪 lacrimal ducts
    🡪 lacrimal puncta /lacrimal canals 🡪 lacrimal sac
2. Palpebral Conjunctiva vs ocular (bulbar) conjunctiva
3. Extrinsic eye muscles move eyeball in socket: 
     lateral rectus, medial rectus, superior rectus,
     inferior rectus, inferior oblique, superior oblique
4. Eye Wall Organization & Internal Anatomy:
    Fibrous Layer: sclera and cornea    
    Vascular Layer:  choroid, ciliary body, pupil,iris
    Sensory Layer/ Retina:  neural layer w/ rods & cones
    Optic disc, Macula lutea, Fovea centralis, Lens
    Suspensory ligaments
    Aqueous humor in anterior compartment
    Vitreous body in posterior compartment


      vision

  Slide of Retina

           sense organs

   hearing and balance

     Using the model, identify:
 1. External Ear with Pinna (auricle) & lobule
     External auditory canal
 2. Middle Ear:  Auditory ossicles: malleus, incus, stapes
     Auditory tube = Eustachian tube = Pharyngotympanic tube
 3. Inner Ear: Bony labyrinth = cochlea + vestibule
     + semicircular canals filled w/perilymph
     Cochlea with vestibule, Oval window, Round window
     Organ of Corti w/neurons that are stimulated by sound waves
     Semicircular canals: anterior, posterior & lateral
     Used to send equilibrium info via Vestibulocochlear nerve
     🡪 thalamus🡪 auditory cortex of temporal lobe

4. Trace Path of Sound Wave through the Ear:
    External Auditory Canal🡪  Tympanic membrane 🡪 Malleus 🡪
    Incus 🡪 Stapes 🡪 Oval Window 🡪   Vestibular duct (scala) of
    Cochlea🡪 Tympanic duct of Cochlea 🡪  Round Window
