NERVOUS SYSTEM EQ: How does the nervous system interact with the endocrine system? Function and Parts ■ A communication and control system that responds to stimuli by receiving, integrating, and responding to signals Function and Parts ■ A communication and control system that responds to stimuli by receiving, integrating, and responding to signals ■ Electrical messages in the nervous system are called action potentials (nerve impulses) Function and Parts ■ A communication and control system that responds to stimuli by receiving, integrating, and responding to signals ■ Electrical messages in the nervous system are called action potentials (nerve impulses) External Stimuli Touch – hot, cold, pain, etc. Internal Stimuli Function and Parts ■ A communication and control system that responds to stimuli by receiving, integrating, and responding to signals ■ Electrical messages in the nervous system are called action potentials (nerve impulses) External Stimuli Touch – hot, cold, pain, etc. Sight Internal Stimuli Function and Parts ■ A communication and control system that responds to stimuli by receiving, integrating, and responding to signals ■ Electrical messages in the nervous system are called action potentials (nerve impulses) External Stimuli Touch – hot, cold, pain, etc. Sight Sound Internal Stimuli Function and Parts ■ A communication and control system that responds to stimuli by receiving, integrating, and responding to signals ■ Electrical messages in the nervous system are called action potentials (nerve impulses) External Stimuli Touch – hot, cold, pain, etc. Sight Sound Smell Internal Stimuli Function and Parts ■ A communication and control system that responds to stimuli by receiving, integrating, and responding to signals ■ Electrical messages in the nervous system are called action potentials (nerve impulses) External Stimuli Touch – hot, cold, pain, etc. Sight Sound Smell Taste Internal Stimuli Function and Parts ■ A communication and control system that responds to stimuli by receiving, integrating, and responding to signals ■ Electrical messages in the nervous system are called action potentials (nerve impulses) External Stimuli Touch – hot, cold, pain, etc. Sight Sound Smell Taste Internal Stimuli Temperature Regulation Function and Parts ■ A communication and control system that responds to stimuli by receiving, integrating, and responding to signals ■ Electrical messages in the nervous system are called action potentials (nerve impulses) External Stimuli Internal Stimuli Touch – hot, cold, pain, etc. Temperature Regulation Sight Blood sugar levels Sound Smell Taste Function and Parts ■ A communication and control system that responds to stimuli by receiving, integrating, and responding to signals ■ Electrical messages in the nervous system are called action potentials (nerve impulses) External Stimuli Internal Stimuli Touch – hot, cold, pain, etc. Temperature Regulation Sight Blood sugar levels Sound Hunger Smell Taste Function and Parts ■ A communication and control system that responds to stimuli by receiving, integrating, and responding to signals ■ Electrical messages in the nervous system are called action potentials (nerve impulses) External Stimuli Internal Stimuli Touch – hot, cold, pain, etc. Temperature Regulation Sight Blood sugar levels Sound Hunger Smell Thirst Taste Function and Parts ■ A communication and control system that responds to stimuli by receiving, integrating, and responding to signals ■ Electrical messages in the nervous system are called action potentials (nerve impulses) External Stimuli Internal Stimuli Touch – hot, cold, pain, etc. Temperature Regulation Sight Blood sugar levels Sound Hunger Smell Thirst Taste Blood pressure Function and Parts ■ A communication and control system that responds to stimuli by receiving, integrating, and responding to signals ■ Electrical messages in the nervous system are called action potentials (nerve impulses) External Stimuli Internal Stimuli Touch – hot, cold, pain, etc. Temperature Regulation Sight Blood sugar levels Sound Hunger Smell Thirst Taste Blood pressure ■ Parts: brain, spinal cord, hypothalamus, neuron, dendrite, peripheral nervous system (PNS), central nervous system (CNS) How does this system function in: ■ Nutrient Absorption: How does this system function in: ■ Nutrient Absorption: sends signals to muscles in the digestive system to speed up digestion How does this system function in: ■ Nutrient Absorption: sends signals to muscles in the digestive system to speed up digestion ■ Regulation: How does this system function in: ■ Nutrient Absorption: sends signals to muscles in the digestive system to speed up digestion ■ Regulation: helps body maintain homeostasis Specialized Cells ■ Electrical messages (also called action potentials) get passed along Specialized Cells ■ Electrical messages (also called action potentials) get passed along ■ Hypothalamus: reads or senses blood levels and then directs different glands of the endocrine system to respond and return the body to homeostasis.
