Question 1 Report

Which of the following is an example of a reflex action?
Answer Details
An example of a reflex action is sneezing. When an irritant enters the nasal passage, the receptors in the nose send a signal to the brain which then sends a message to the muscles in the chest, throat, and face to quickly expel air, removing the irritant. This action is automatic and involuntary, occurring without conscious thought or effort. Biting, dancing, singing, and talking are not reflex actions as they involve more complex movements and cognitive processing.
