Back

The primary function of the nervous system is to transmit signals between different parts of the body, coordinating actions and responses.

Front

What are the two main components of the central nervous system?

Back

The two main components of the central nervous system are the brain and spinal cord.

Front

Define reaction time in the context of sensory processing.

Back

Reaction time is the interval between the perception of a stimulus and the initiation of a response.

Front

What physiological response is commonly associated with fear?

Back

Sweating is a common physiological response associated with fear.

Front

How does practice influence reaction time?

Back

Practice can improve reaction time by enhancing neural pathways and motor skills, allowing for quicker responses.

Front

What analogy is often used to describe the function of nerves in the body?

Back

Nerves are often compared to wires that carry electrical signals throughout the body.

Front

What role does the brain play in processing sensory information?

Back

The brain processes sensory information by interpreting signals received from sensory organs and coordinating appropriate responses.

Front

What is the significance of the spinal cord in the nervous system?

Back

The spinal cord serves as a major conduit for information traveling between the brain and the rest of the body.

Front

What is a reflex action, and how does it relate to the nervous system?

Back

A reflex action is an automatic response to a stimulus that occurs without conscious thought, mediated by the nervous system.

Front

How can stress affect reaction time?

Back

Stress can negatively impact reaction time by causing distractions and impairing cognitive function.
