Why are reflex actions faster than voluntary actions?
Reflex actions are faster because they are processed by the spinal cord and do not involve the brain. This allows the body to respond quickly to harmful stimuli without conscious thought.
What is the difference between the CNS and PNS?
The CNS (Central Nervous System) consists of the brain and spinal cord, which process and coordinate information. The PNS (Peripheral Nervous System) consists of nerves that connect the CNS to the rest of the body, carrying sensory and motor signals.
How does the nervous system help animals respond to stimuli?
The nervous system detects changes in the environment (stimuli) through sensory receptors, processes the information in the brain and spinal cord, and generates an appropriate response through motor neurons.
