Question 10

Somatotopic Arrangement of ant and lat spinothalamic and corticospinal

Answer 10

C-T-L-S

Question 11

somatotopic arrangement of DCML

Answer 11

S-L-T-C

Question 12

exp central cord syndrome

Answer 12

(B) motor and suoerficial sensory loss d/t damage on C-T of ant/lat spinothalamic and corticospinal

can walk but not properly d/t lack of pos sense d/t damge on C-T-L-S of DCML

Question 13

exp anterior cord syndrome

Answer 13

affects LST, AST, ACS

DCML IS SPARED - intact deep sensation

level of lesion - (B) LMN paralysis

below level of lesion - (B) loss of pain, temp, light touch; spastic paralysis

Question 14

exp post cord syndrome

Answer 14

DCML affected = Ipsilateral loss of proprioception, vibration sense, two-point discrimination and light touch below the lesion

Spinothalamic and corticospinal or motor is spared

Question 15

exp brown-sequard syndrome

Answer 15

leads to ipsilateral loss of discriminative touch, vibration, proprioception and weakness and spasticity of muscles below the level of the lesion

leads to contralateral loss of pain and temperature sensation beginning one or two segments below the lesion
