cranial nerves - test
I - close eyes, place something familiar for the patient to smell and identify (orange/lemon peel, coffee, or vinegar) under each nostril alone
II
- acuity - snellen chart with and without visual aids
- colour - ishihara plates identify patients who are colour blind
- fields - asking the patient to look directly at you whilst you wiggle one of your fingers in each of the four quadrants; ask the patient to identify which finger is moving; inattention can be tested by moving both fingers at the same time and checking the patient identifies this
- reflexes - place one hand vertically along the patients nose to block any light from entering the eye which is not being tested; shine a pen torch into one eye and check that the pupils on both sides constrict; tested on both sides
- fundoscopy - performed on both eyes
III / IV / VI - head perfectly still directly in front of you, you should draw two large joining H’s in front of them using your finger and ask them to follow your finger with their eyes; the patient does not move their head
V
- sensory - lightly touching the face with a piece of cotton wool followed by a blunt pin in three places on each side of the face: around the jawline, cheek, forehead; corneal reflex - lightly touching the cornea with the cotton wool; should cause the patient to shut their eyelids
- motor - ask the patient to clench their teeth together, observing and feeling the bulk of the masseter and temporalis muscles; open their mouth against resistance; jaw jerk on the patient by placing your left index finger on their chin and striking it with a tendon hammer - cause slight protrusion of the jaw
VII - asking the patient to crease up their forehead (raise their eyebrows), close their eyes and keep them closed against resistance, puff out their cheeks and reveal their teeth
VIII
- Rinne test - place a sounding tuning fork on the patient’s mastoid process and then next to their ear and ask which is louder; normal patient will find the second position louder
- Weber’s test - place the tuning fork base down in the centre of the patient’s forehead and ask if it is louder in either ear; should be heard equally in both ears
IX - tested with the gag reflex or by touching the arches of the pharynx
X - asking the patient to speak gives a good indication to the efficacy of the muscles; uvula should be observed before and during the patient saying “aah”; check that it lies centrally and does not deviate on movement
XI - ask the patient to shrug their shoulders and turn their head against resistance
XII - observe the tongue for any signs of wasting or fasciculations; ask the patient to stick their tongue out; if the tongue deviates to either side, it suggests a weakening of the muscles on that side

temporomandibular joint / TMJ motions - retrusion
anterior-posterior movement within the upper joint space
- mandibular condyle and disk move as one unit against the mandibular fossa and articular tubercle of the temporal bone
- no rotation; forward and backward motions of all parts of the mandible are equal
- horizontal plane
- vertical axis
arteries
.
veins
.
temporomandibular joint / TMJ motions - depression
- lower joint space - convex-on-concave articulation where the mandibular condyle rotates on the disk creating an anterior glide of the condyle while the distal end (ramus/angle) moves posteriorly
- upper joint space - involves gliding the disk forward and downward under the articular tubercle; articular disk is more firmly attached to the mandible than the temporal bone, it allows the disk to move forward with the condyle of the mandible when the mouth opens; It returns posteriorly when the mouth closes
- sagittal plane
- frontal axis
lymph angion
.
lymph node
.
lymph system
.
temporomandibular joint / TMJ
synovial joint
- modified hinge shape; allows some gliding motion, it is not a pure hinge joint
third-class lever system
- force arm (distance from joint axis to muscle attachment) being shorter than the resistance arm (distance from joint axis to con- tact point of teeth)
- contact between the more anterior molars or front teeth creates a long resistance arm and less biting force
- the greatest amount of biting force can be generated at the rear molars because the resistance arm is the shortest
temporomandibular joint / TMJ motions - elevation
- reverse action; gliding of the disk and condyle posteriorly and superiorly in the upper joint space and rotation of the condyle on the disk creating a posterior glide within the lower joint space
- sagittal plane
- frontal axis
temporomandibular joint / TMJ motions - lateral deviation
- one condyle rotating in the mandibular fossa while the other condyle glides forward
- move the mandible toward the left, the left condyle will rotate and the right condyle will glide forward
- horizontal plane
- vertical axis
temporomandibular joint / TMJ motions - protrusion
anterior-posterior movement within the upper joint space
- mandibular condyle and disk move as one unit against the mandibular fossa and articular tubercle of the temporal bone
- no rotation; forward and backward motions of all parts of the mandible are equal
- horizontal plane
- vertical axis

.
temporomandibular joint / TMJ articular disk
divides the joint space into two separate compartments
- larger upper joint space - superioir surface is both concave and convex to accommodate the shape of the fossa
- smaller lower joint space - concave inferior surface accommodates the convex surface of the condyle and allows the joint to remain congruent (compatible) throughout the motion
