General Inspection
During the general inspection of the cranial nerves, we should look for whether the patient has any ptosis, abnormal eye movements and facial asymmetry. We should also inspect for whether there are any neuro-cutaneous features (for example in patients with tuberous sclerosis and neuro-fibromatosis), syndromal features etc.

Intention tremor can be elicited by the finger-nose test. In normal patients, the movements between the physician’s finger and patient’s nose should be smooth, but adjustment is allowed according to the patient’s upper limb power. This man has intention tremor and impaired finger-nose test on the right side, whilst the left side is normal. Discussion on intention…
Normal Cerebrospinal Fluid The photos shown here is that of normal cerebrospinal fluid after a lumbar puncture. Normal cerebrospinal fluid is colourless and odorless. Xanthochromia The cerebrospinal fluid here shows xanthochromia (Figure 1), meaning of yellow discolorization. Presence of xanthrochromia means that there is presence of red cells in the cerebrospinal fluid. With time, the red…
One can appreciate from this photo that there is significant lower limb wasting (or muscle atrophy) of the right leg compared to the left. The right leg is also shorter compared to the left. Muscle wasting (or atrophy) is due to denervation of the muscle supplied by the motor nerve and occurs in lower motor…

Inspection of the Upper Limbs After adequate exposure, one should then lay the patient’s arms out comfortably. The examiner should stand at the end of the bed / facing the patient if the patient is…
These two videos are from a middle-aged man presenting with progressive bilateral lower limb and right upper limb weakness for few months. In the first video, there are prominent fasciculations over the entire right upper limb. Whilst in the second video, fasciculations can also be noted over both lower limbs, but more prominent on the…
In this video, one can appreciate that the patient has a lower motor neuron type of weakness affecting the right facial nerve. On asking the patient to look upwards (stimulation of the frontalis muscles), one can appreciate the lack of wrinkles over the forehead on the right side compared with the left. On asking the…
