Question

Page 311 Name LABORATORY ASSESSMENTe 29 The corresponds to tho indicated LAaring Outomm Reflex Arc and Somatic Reflexes PART A: Assessments Complete the following table: At Response Observed Effector Muscle Involved Response During Mental Distraction or Fatigue (no change, more, or less) Reflex Tested Patellar Calcaneal Biceps Triceps Plantar What conclusions can you make when comparing results of somatic reflexes under typical laboratory conditions to the results under conditions of mental distraction or fatigue? A1

Explanation / Answer

When results are compared between laboratory findings and during mental distraction reflex will be enhanced during mental distraction.This is called as jendrassik maneuver. So this procedure enhance the reflex by distracting the person from voluntary inhibition or facilitation of reflex.

reflex tested response obeserved effector muscle involved response during mental distraction or fatigue patellar normal quadriceps femoris more calcaneal normal gastrocnemius muscle more biceps
normal biceps brachii triceps normal triceps brachii
less plantar
normal flexor hallucis longus more
