endocrine and nervous system

What is the primary function of the nervous system?

The nervous system's primary function is to coordinate rapid, short-term responses to stimuli by transmitting electrical and chemical signals throughout the body. It controls senses, movement, thoughts, and emotions.

What is the primary function of the endocrine system?

The endocrine system's primary function is to regulate long-term processes such as growth, metabolism, reproduction, and stress responses by secreting hormones into the bloodstream.

How do the nervous and endocrine systems primarily differ in their communication methods?

The nervous system uses electrical impulses (action potentials) and neurotransmitters for rapid, localized communication, while the endocrine system uses hormones transported through the bloodstream for slower, widespread, and sustained communication.

What are the two main divisions of the nervous system?

The two main divisions are the Central Nervous System (CNS), consisting of the brain and spinal cord, and the Peripheral Nervous System (PNS), which includes all nerves outside the CNS.
