1

Which body areas does the posterior ramus serve?

Back of neck and trunk

2

Which body areas does the anterior ramus serve?

Limbs, anterior and lateral trunk

3

What happens in knee jerk reaction in terms of neurones?

Afferent impulses carried to dorsal horn from stretch receptors

Efferent impulse cause contraction of muscle that reverse stretch

Efferent impulses inhibit contraction of antagonistic muscles

Weak
Unsteady
Wasting

Reduced power

Normal sensation

Absent reflexes

Damage to large fibre sensory neurones would caue what symptoms?

Numbness
Paraesthesia
Unsteady

Normal power

vibration and JPS reduced

Absent reflexes

6

Damage to small fibre neurones would cause what symptoms?

Pain
Dyesthesia
