Brain Excitatory & inhibitory signals via neurons. Glial cells, including astrocytes & microglia, neural functions. Nervous system. AI generated Brain Illustration: This graphic provides insight into the intricate workings of the brain, emphasizing key components such as neurons, excitatory and inhibitory functions, glial cells, including astrocytes and microglia, and the broader nervous system.Neurons, the fundamental units, transmit signals either excitatorily or inhibitorily, regulating communication within the nervous system. Glial cells, comprising astrocytes and microglia, play pivotal roles in supporting neural function and maintaining overall brain health.Astrocytes contribute to the brain s homeostasis by regulating neurotransmitter levels and providing metabolic support to neurons. Meanwhile, microglia act as the brain s immune cells, monitoring for potential threats and participating in the defense against infections or injuries.The nervous system, comprising the central nervous system (CNS) and peripheral nervous system (PNS), orchestrates communication throughout the body. The CNS, encompassing the brain and spinal cord, processes and integrates information, while the PNS extends throughout the body, facilitating communication between the CNS and peripheral organs.This illustration captures the complexity of these neural interactions, showcasing the balance between excitatory and inhibitory signals, the supportive functions of glial cells, and the coordination between the central and peripheral nervous systems. The graphic serves as a visual representation of the dynamic interplay within the brain and the broader nervous system.
