Q

Flexor withdrawal reflex

  • Weeks of Gestation at which Reflex Appears
  • When reflex integrates after birth
  • Stimulus
  • Response
A
  • Weeks of Gestation at which Reflex Appears: 28
  • When reflex integrates after birth: 1-2 months

  • Response: Flexion withdrawal of leg

I think this reflex was most important to determine if it is absent?? Since we have some of this as adults as well. So most problematic if not present.

50
Q

What does STNR stand for?

A

Symmetrical tonic neck reflex

51
Q

What is something to note about the times we learned for when the reflexes integrate?

A

A weaker reflex response to the stimulus might generally occur for a few more months

(so it is normal for there to be weak signs of it for a few more months after the time we learned).
