30 PAGES (5684 WORDS) Physiology Paper





Brown-Séquard syndrome, also known as Brown-Séquard's

hemiplegia
and Brown-Séquard's

paralysis
, is a loss of sensation and motor function (
paralysis and anesthesia) that is caused by the lateral hemisection

(cutting) of the
spinal

cord
. This may be

seen most often in the cervical (neck) or thoracic spine. Other synonyms are hemiparaplegic syndrome, hemiplegia ethemiparaplegiaspinalis,

and spinal hemiparaplegia
Brown-Séquard syndrome is

characterized by loss of motor function(i.e.

hemiparaplegia), loss of vibration sense and fine touch, loss ofproprioception (position sense), loss

of two-point discrimination, andsigns

of weakness on the ipsilateral (same side) of the spinal injury.
