Presentation transcript:

What you will learn today . . . Reflexes are involuntary, often self-protective movements, that bypass the brain Reflexes start with a stimulus and end with an action in response to a stimulus

Reflexes and Reflex Arcs

What is a reflex? A rapid, involuntary response to a stimulus Follow a simple nerve pathway called a reflex arc

Example of a Reflex Arc

Example of a Sneezing as a Reflex

Patellar Reflex

Achilles Reflex

Triceps Reflex

Biceps Reflex
