# Nervous System The image describes the nervous system in a diagrammatic format. ## System Function - **Peripheral System:** Interprets sensations and controls effectors. - **Central System:** Contains organs and their functions. ## Central System Components and Functions 1. **Brain:** * Controls center * Relays messages (by Spinal Cord) 2. **Spinal Cord:** Relays messages 3. **Three Parts of the Brain and their functions:** * **Cerebrum:** Interprets senses, regulates emotion, and reasoning. * **Cerebellum:** Maintains balance, posture, coordination, and fine motor skills. * **Brain stem:** Connects brain to spinal cord and controls automatic functions like breathing. ## Peripheral System Components and Functions - **Peripheral Nerves:** * Sends signals ## Neuron - **Neuron (cell):** * *Transmits nerve impulses* * Respond to stimulation * Release neurotransmitters The image also includes arrows to show the flow of information between different parts of the nervous system. A drawing of a brain is also shown in the image.
