2. Spinothalamic tract
3. Trigeminothalamic pathway
Dorsal column
Touch, pressure, vibration, and conscious
proprioception from the limbs, trunk, neck, and posterior head.

Made up of the gracile fasciculus (medial), which propagates information from the lower body, and the cuneate fasciculus (lateral), which propagates information from the upper body.

Decussate at medulla, cross to medial lemniscus of midbrain.
Spinothalamic pathway
Pain, temperature, itch, and tickle from the
limbs, trunk, neck, and posterior head.

Decussate in the spinal column
Trigeminothalamic pathway
Tactile. thermal, and pain sensations from the face, nasal cavity, oral cavity, and teeth. Through the trigeminal nerves.
Spinocerebellar tracts

MS
Inflammation of CNS (i.e. does not effect peripheral nerves). Steroids for exacerbations, otherwise - beta interferon and azathiprine.
Becker's muscular dystrophy
X-linked (therefore, vast majority male). Less severe and less common than DMD. Symptoms appear later on in childhood and early adulthood. Main symptoms are lower limb weakness (frequent falls, Gower's manoeuvre), fatigue, and cardiac disease.
Duchenne's muscular dystrophy
X-linked. Muscle destruction due to lack of dystrophin. Symptoms typically appear before age 6. Early signs include pseudohypertrophy of calf muscle. Life expectancy is around 25.

Findings typically include ataxia of the gait and trunk, nystagmus, dysarthria, loss of position and vibration sense in lower limb, optic atrophy, pes cavus and cardiomyopathy.

Basically - Ataxia + nystagmus + optic atrophy in a young patient is probably Friedrich's ataxia.

If vesicles in auditory canal or on soft palate, diagnosis is Ramsay-Hunt syndrome
Explain the difference between bulbar and pseudobulbar palsy in broad terms
The 'bulb' is the medulla, and the palsy in question is caused by insult to the cranial nerves that run through it (IX-XII).

A bulbar palsy is a weakness of the LMN type, typically caused by MND, syringobulbia, and Gullain-Barre syndrome. Presentation includes dysphagia, dysarthria, and nasal regurgitation. Tongue is wasted and fasciculating.

Pseudobulbar palsy is an UMN weakness of the same muscle groups. Typically caused by stroke and MS. Presents with dysarthria, dysphagia, and nasal regurgitation. Jaw jerk is exaggerrated. Tongue is small and spastic with no fasciculation.
