Frequently Asked Questions
What is the difference between the nervous system and the endocrine system in controlling behavior?
The nervous system uses electrical and chemical messages via nerve impulses for fast, localized responses, whereas the endocrine system uses hormones released into the bloodstream for slower, longer-lasting effects on growth, metabolism, and mood.
How do heredity and environment interact to shape human behavior?
Heredity provides the genetic blueprint and biological potential, while the environment determines how much of that potential is actually developed and expressed through learning, nutrition, and social experiences.
What are the main divisions of the human nervous system?
The human nervous system is broadly divided into the Central Nervous System (CNS, consisting of the brain and spinal cord) and the Peripheral Nervous System (PNS, consisting of the somatic and autonomic nervous systems).
