Explanation Many vertebrates will immediately cringe, jump, leap, or take flight in response to a loud noise, which could represent sudden danger. Blinking our eyes when something flies towards it or raising our arm when a ball is thrown to us, coughing and sneezing are the examples of reflexes. Other reflexes, such as the patellar tendon reflex are important for postural changes and locomotion...

Chapter 33, Problem 2CBQ

Summary Introduction

To write:

About the reflexes that occur in animals and humans.

Introduction:

Reflexes are among the evolutionarily oldest and most important features of nervous systems, because they allow animals or human to respond quickly to potentially dangerous events. Reflex occurs due to neural pathways called reflex arcs which can act on an impulse before that impulse reaches the brain.
