Neuroanatomical refers to the structure and organization of the nervous system, including the brain, spinal cord, and peripheral nerves. It encompasses both gross anatomy and microanatomy, as well as the relationships between neural elements such as neurons, glial cells, synapses, and supporting vasculature. The field informs how neural circuits are arranged to support perception, movement, cognition, and autonomic functions.

The nervous system is divided into the central nervous system (CNS), comprising the brain and spinal cord, and the peripheral nervous system (PNS), including cranial and spinal nerves and the autonomic network. The brain is traditionally described in terms of major subdivisions—the cerebrum, cerebellum, brainstem, and diencephalon—and further by lobes, gyri, and sulci. Subcortical structures such as the thalamus, basal ganglia, hippocampus, and amygdala contribute to sensory processing, motor control, memory, and emotion. The spinal cord contains ascending sensory and descending motor pathways and segmental circuitry that coordinates reflexes and autonomic functions.

Neuroanatomical study employs histology, neuroimaging, and neurotracing methods to map structure and connections. Techniques include magnetic resonance imaging (MRI), functional MRI (fMRI), diffusion tensor imaging (DTI), tractography, electrophysiology, and various staining methods. Neuroanatomical atlases provide standardized references for localization in research and clinical practice.

Clinically, neuroanatomy guides lesion localization, informs neurosurgical planning, and aids interpretation of neurological signs. A precise understanding of neural architecture underpins diagnosis, treatment planning, and the study of neurological disorders.
