 Are all parts of the eye seen here involved in the function of sight?  Are there any parts that could potentially sustain damage without making the eye as a whole lose its function?  embed/EevqmzkGJaE

 Turn to page 277 in your lab books and do activities A and B (Acuity and Astigmatism).  We aren’t using wall charts so 1 partner will hold the lab book chart and stand 1 foot (1 tile square) away

 This is where I’m going to put your slide show.

Lesson 7.1: The Eye Lesson 7.2: The Ear Lesson 7.3: Smell and Taste The Sensory Systems

The Eye Chapter 7: The Sensory Systems

 anatomy of the eye  external  internal  vision  injuries, diseases, and disorders of the eye

 tarsal glands  ciliary glands conjunctiva lacrimal glands

 humors  aqueous  vitreous  tissue layers  sclera cornea  choroid pupil iris  retina rods and cones

 retina  impulse  optic nerve  brain  optic chiasma  optic tracts  occipital lobe

 conjunctivitis  also known as pink eye  cataracts  glaucoma  macular degeneration  diabetic retinopathy  vitreous floaters

Fill in the blanks with: choroid, cornea, cones, or vitreous. 1. The pupil is part of the _______________ tissue layer. 2. The two humors are aqueous and _______________. 3. The retina contains the rods and _______________. 4. The clear part of the sclera is the _______________.

 What cranial nerve is used for vision?  Why were the doctors in the video from the last class worried about that nerve being damaged?  What are the two kinds of cells in the retina and their functions?  Snellen Chart  Acuity  Astigmatism

 What part of the eye did the YouTuber say they insert the implant into?  What cells are in that part of the eye?  Why would putting it there be important?  click here click here

 Teacher gives worksheet of questions or problems.  Partner “A” will be responsible for the left-hand side. Partner “B” will be responsible for the right-hand side.  Partner “A” has the one pencil and the one paper. Partner “A” reads the question aloud and works through the problem aloud.  Partner “B” coaches and praises.  Partner “A” gives Partner “B” the pencil and paper.  Then Partner “B” takes the paper to the teacher for it to be approved.  Partner “B” reads the question aloud and works through the problem aloud.  Partner “A” coaches and praises.  Keep taking turns until teacher calls time.  Be prepared to share partner’s responses.  If you are caught breaking these rules, you have to do the entire worksheet by yourself.

 A. A clear structure that refracts light and can change in curvature  B. A tiny ring of muscles that change the shape of the lens  C. The pigmented ring of muscles that change the size of the pupil  D. Works with the lens to refract light and helps the eye to focus  E. Move the eye around  F. Transmits signals from the eye to the brain  G. Gives the eye its shape and protects the inner parts  H. A thin layer of cells that convert light into nerve signals  13. ______ External muscles  14. ______ Retina  15. ______ Cornea  16. ______ Lens  17. ______ Optic nerve  18. ______ Iris  19. ______ Sclera  20. ______ Ciliary muscles

1. The innermost layer of the eye is the _____ 2. What is the name of the iris’s hole? 3. What cranial nerve is responsible for vison? (give the name and number) 4. Cataracts is a clouding of what part of the eye? 5. What is an astigmatism? 6. What is the name of the gland that secretes tears? 7. Where in the eyeball is the retina located? a) Front of the eye close to the iris b) Back of the eye near the optic nerve c) Covering the entire eye ball along with the sclera d) Above the tear ducts

The Ear Chapter 7: The Sensory Systems

 1) What is the first word that come to mind when you see the logo to the left?  2) What does the commercial portray about the benefits of the technology that bears the logo to the left?  3) What are some of the unstated disadvantages of using the technology that bears the logo to the left?  video video

 Using some of the data on the bulletin, what can we infer about the reason that teens incur hearing problems?  How could we find out if this is factual?  Let’s plan and execute a brief investigation. videovideo  Hearing Test – Brain Games Assessment!

 Describe the major anatomical structures of the outer ear, the middle ear, and the inner ear.  Explain the process by which hearing occurs, from the transmission of sound waves to the perception and interpretation of sound.  Explain the role of the inner ear in helping your body to maintain equilibrium, or balance.  Describe some common causes of deafness.  Describe some common ear infections

 anatomy of the ear  functions of the ear  disorders and infections of the ear

 external ear  auricle, auditory canal, and tympanic membrane  middle ear  ossicles  hammer, anvil, and stirrup  Eustachian tube  internal ear  cochlea, vestibule, and semicircular canals

 hearing  cochlear duct Inside the organ of Corti  hair cells Short stiff = high pitch Long flexible = low pitch  equilibrium  semicircular canal

 deafness  Tinnitus – damaged hair cells  external otitis (swimmer’s ear)  otitis media (middle ear infection)  labyrinthitis (inner ear infection)

Smell and Taste Chapter 7: The Sensory Systems

 You are going to study if the sense of smell affects your sense of taste. You are going to see if you can identify the flavor of skittles without looking at them under two conditions, just your eyes closed and your eyes closed and holding your nose.

 olfactory sense (sense of smell)  injuries and disease of the nose  gustatory sense (sense of taste)  disorders of the tongue

 olfactory region  olfactory receptor cells  olfactory hairs  olfactory filaments  olfactory nerve  olfactory bulb
