Anastomosis is least efficient at the region of lateral columns
খ
Cervical and lumbar segments have rich vascular supply
গ
T1 to T4 segments are least vulnerable to ischemia
ঘ
Anterior spinal artery thrombosis causes ischemia of anterior 2/3rd of the cord, sparing the posterior column, hence leads to dissociated sensory loss

Special points Regarding blood supply of spinal cord 1. Anastomosis is least efficient at the region of lateral columns 2. Cervical and lumbar segments have rich vascular supply 3. T1 to T4 segments are most vulnerable to ischemia 4. Anterior spinal artery thrombosis causes ischemia of anterior 2/3rd of the cord, sparing the posterior column, hence leads to dissociated sensory loss.
