👉 Neuroanatomy is a branch of anatomy that studies the structure and function of nervous systems, including both the internal and external structures within the brain. It includes the study of neurons, synapses, nerves, blood vessels, and other components of the nervous system. The field of neuroanatomy aims to understand how the body functions in response to stimuli and how different parts of the nervous system work together to maintain homeostasis (the balance between internal and external systems).
