  1. Unit 7 – Eye, Ear, and Musculoskeletal System Terry Bond Adjunct Faculty Kaplan University

  2. What is due this at the end of this unit? • Discussion participation • Seminar participation – synchronous through tonight’s seminar or another flex seminar or asynchronous via Option 2 post • Quiz

  3. Anatomy of the Eye • Describe the functions of these anatomical parts Iris Pupil Sclera Cornea Retina Lacrimal glands Aqueous humor Vitreous humor

  4. Did you know? • When an image passes through the lens of the eye – the image is actually upside down. The optic nerve picks up the image and the brain then corrects the visual and “rights” the image. Cool, Huh!

  5. Anatomy of the Ear • The ear provides us the ability to hear and balance • There are 3 parts of the ear: inner ear, middle ear, and external ear

  6. Combining Word Forms for Ears and Eyes • Corne/o • Kerat/o • Ocul/o • Opthalm/o • Audi/o • Labyrinth/o • Myring/o • Tympan/o • Ot/o

  7. Disease and disorder – built from word parts • Conjunctivitis • Diplopia • Keratitits • Opthalmalgia • Opthalmologist • Labyrinthitis • Otalgia • Otopyorrhea • Tympanitis • Otitis media or externa

  8. Disease and disorders – not built from word parts • Astigmatism • Cataract • Glaucoma • Macular degeneration • Vertigo • Acoustic neuroma • Meniere’s disease

  9. Diagnostic terms • Opthalmoscope • Optometry • Tonometer • Otoscope • Audiogram • Typanometer • Audiometry

  10. Abbreviations • OU - both • OS - left • OD – right • EENT • ENT • OM

  11. Let’s talk: Musculoskeletal System Name major organs of the musculoskeletal system: Cranium/skull Vertebrae Spinal column Large bones, e.g. femur, radius, sternum, ribs Small bones, e.g. metacarpals,

  12. Structure of bone • Periosteum – outermost layer of bone • Compact bone – the hard layers of bone tissue that lie beneath the periosteum • Cancellous (spongy) bone – contains spaces which appear like a sponge and encased in layers of compact bone • Endosteum – membranous lining of hollow cavity of the bone • Diaphysis – shaft of the long bones

  13. Skeletal bones • Maxilla • Vertebrae • Sacrum • Clavicle • Sternum • Humerus • Carpal bones • Pelvis • Femur • Fibula • Tibia • Ulna • Radius

  14. Joints • Help hold our bones together and provide ability to move • Meniscus • Synovia • Tendon • Ligament • Articular cartilage

  15. Muscles • Muscles are attached to the bones to help make movement possible, also located in internal organs such as the heart, intestines, stomach, blood vessels to help fluids and nutrients move

  16. Medical terms • Arthritis • Fibromyalgia • Kyphosis • Myasthenia • Osteomyelitis • Tendonitis • Scoliosis • Bunion • Fracture • Herniated disk • Osteoporosis

  17. Diagnostics • Arthroscopy • Electromyogram (EMG) • Magnetic resonance imagining (MRI) • Bone scan • Bone densitometry
