Reaction vs. Reflex Time

Front

What is reaction time?

Back

The time taken to respond to a stimulus after it is perceived.

Front

What is reflex time?

Back

The time taken for an involuntary response to a stimulus, often faster than reaction time.

Front

What happens to reaction time as task complexity increases?

Back

Reaction time increases (becomes slower).

Front

What is a reflex arc?

Back

A neural pathway that controls a reflex action, involving sensory neurons, interneurons, and motor neurons.

Front

What role do sensory neurons play in a reflex arc?

Back

They transmit sensory information from receptors to the spinal cord.

Front

What role do motor neurons play in a reflex arc?

Back

They carry signals from the spinal cord to muscles to elicit a response.

Front

What are interneurons?

Back

Neurons that connect sensory and motor neurons within the central nervous system.

Front

True or False: Interneurons are found throughout the body.

Back

False; they are primarily located in the central nervous system.

Front

Why are reflex actions important?

Back

They provide quick, involuntary responses that can prevent injury and are essential for survival.

Front

What is the central nervous system (CNS)?

Back

The part of the nervous system that includes the brain and spinal cord.
