This is an extract of our Lesions document, which we sell as part of our Neuroscience 1 Notes collection written by the top tier of Oxford students.
The following is a more accessble plain text extract of the PDF sample above, taken from our Neuroscience 1 Notes. Due to the challenges of extracting text from PDFs, it will have odd formatting:
Lesions
Spinal cord injuries Complete cord transection syndrome:
-Complete loss of all sensibility and voluntary movement below level of the lesion-can be caused by fracture, dislocation of vertebral column by a bullet or stab wound or by expanding tumour Symptoms:
-Bilateral lower motor neuron paralysis, muscular atrophy in segment of lesion - due to damage of motor neurons in ventral horns
-Bilateral spastic paralysis below the level of lesion- A bilateral Babinski sign is present and depending on level of the segment of spinal cord damaged -due to interruption of corticospinal tracts
-Bilateral loss of all sensations below the level of lesion-loss of tactile discrimination and vibratory and proprioceptive sensations due to bilateral destruction of ascending tracts in posterior white columns. Due to damage to lateral and anterior spinothalamic tracts
-Bladder and bowel functions no longer under voluntary control-all descending autonomic fibres are destroyed Anterior cord syndrome
-Cord contusion during ventebral fracture, from injury to anterior spinal arteryischaemia of the cord Symptoms:
