Session 14/ Checklist: Ear

Ear
Curricular Objectives
By the end of this session students are expected to:
Theory
1. Outline the three parts of the ear, their location and subdivisions
2. Summarize the composition and main features of the auricle
3. Describe the two parts of EAM, and compare the structure of the skin of lining each part
4. Appraise the importance of the flexibility of the EAM in examination of ear
5. Outline the location of tympanic membrane & the main features of its external surface
6. Review the nerve supply of EAM & tympanic membrane
7. Define the middle ear and list its content, function and sensory supply
8. Underline the location, function, & nerve supply of tensor tympani & stapedius muscles
9. Describe the boundaries and relations of the middle ear essential in clinical practice
10. Describe the auditory (Eustachian) tube and its functional importance
11. Review the function and clinical importance of middle ear communications
12. Explain the involvement of middle ear in upper respiratory tract infections
13. Conclude the structure affected by middle ear infection from their manifestations
14. Outline the location and the structural components of internal ear
15. Summarize the function and nerve supply of different parts of membranous labyrinth
16. Discuss the structural organization of the cochlea and cochlear duct
17. Review the content of the internal auditory meatus
Practical
1. Recall the function of each of the three parts of the ear
2. Identify the main landmarks of the auricle and external auditory meatus (EAM)
3. Use the tragus to identify and palpate the Temporomandibular joint
4. Distinguish the temporal bone and its different parts
5. Recognize tympanic membrane and label main landmarks of its external surface
6. Locate the middle ear and label the ossicles
7. Identify the oval and round windows and the structures closing them
8. Trace the chorda tympani on the surface of tympanic membrane
9. Identify the tensor tympani & stapedius muscles and notice their attachment
10. Mark the Aditus & auditory tube and the cavities into which they open
11. Identify the three different parts forming the internal ear and state their function
12. Trace the cochlear and vestibular nerves within the petrous bone
13. Label the EAM and mastoid air cells in a lateral skull X-ray
14. Palpate the mastoid process for tenderness related to middle ear infection
