- Health professions place importance on communication skills and knowledge application.
- Course outline is organized into pediatric/congenital and acquired/adult disorders.
- Lectures will have an anatomical/systemic division
- There will be one assignment (15%) and a midterm/final exam
- No textbooks required for the course
- Lecture notes will be available online
Lecture Outline for Today
- Introduced the importance of understanding medical terms/definitions
- Medical terminology uses prefixes and suffixes to describe parts and functions
- Key terms: oto (ear), -itis (inflammation), Myalgia (muscle pain), Rhea (fluid), Ectomy (removal), and related medical terminology were discussed
- Sensitivity and specificity in testing were introduced as terms used in identifying tests
- Sensitivity refers to correctly identifying a condition when present
- Specificity refers to correctly identifying a condition when absent
- A table outlining sensitivity and specificity is a useful tool in testing
- Course will review anatomy and physiology of the ear
Anatomy of the Inner Ear
- Inner ear is also known as the "labyrinth"
- Comprises three semicircular canals, the cochlea (hearing organ), and the vestibule/sacrum
- Bony labyrinth surrounds the membranous labyrinth internally
- Membranous labyrinth is filled with fluid
