Study Notes
Cranial Nerve Assessment
- The trigeminal nerve (CN V) is responsible for assessing facial sensation, including the forehead, cheek, and lower jaw on both sides of the face.
Jaw Function Assessment
- The masseter muscle test involves clenching the jaw and then opening it while the examiner applies resistance.
Eye Alignment Assessment
- The cover-uncover test is performed to assess misalignment of the eyes that is always present.
Hip Joint Assessment
- The purpose of performing Thomas and Trendelenburg's tests is to assess the hip joint.
- Contralateral hip lifting up during certain movements suggests hip instability or weakness.
- The McMurray Test is used to assess the hip joint, and pain with tibial internal rotation and varus stress may indicate a meniscal tear.
Spinal Cord Mobility Assessment
- Decreased mobility in arthritis is indicated by limited spinal cord range of movement.
Hearing Assessment
- The purpose of Rinne's test is to assess hearing function during a cranial nerve examination.
- During Weber's test, the tuning fork is placed on the midline of the forehead or the vertex of the skull to determine hearing function.
- If the person hears the sound more in one ear than the other during Weber's test, it suggests a conductive hearing loss in the ear where the sound is louder.
Vestibular Testing
- Nystagmus (abnormal eye movements) or lack of response to vestibular testing may indicate a potential lesion.
