Brain
The central organ of the nervous system. Its interconnected regions support perception, movement, memory, language, and the regulation of bodily functions.
The brain, spinal cord, and peripheral nerves carry and process signals. They support sensation, movement, coordination, and automatic regulation of body functions.
The BodyParts3D reference dataset includes 139 modeled nervous system pieces across 124 FMA concepts, including detailed cortical gyri, deep gray matter nuclei, brainstem subdivisions, cerebellum, and cranial nerves.
Carries and processes electrical and chemical signals across the central and peripheral nervous systems.
Integrates sensory input to support perception, memory, language, and cognitive function.
Coordinates voluntary movement and balance through cortical, subcortical, cerebellar, and brainstem pathways.
Provides automatic regulation of vital bodily functions via hypothalamic and autonomic circuits.

The central organ of the nervous system. Its interconnected regions support perception, movement, memory, language, and the regulation of bodily functions.
A major hindbrain structure located posterior to the brainstem that coordinates voluntary movement, posture, balance, and motor learning.
The central part of the brainstem bridging the midbrain and medulla oblongata, serving as a relay between the cerebral cortex and cerebellum.
The rostral segment of the brainstem involved in visual and auditory reflexes, eye movement control, and motor pathways.
A diencephalic region that regulates homeostasis, autonomic nervous activity, temperature, and endocrine signaling via the pituitary gland.
The midline structure at the base of the brain where nasal fibers of the right and left optic nerves cross en route to the visual pathways.
A paired deep gray matter structure of the diencephalon that relays sensory and motor signals to the cerebral cortex.
Every anatomical structure assigned to the Nervous system layer in atlas.json. Curated landmarks include a Learn more guide, and all 124 structures can be selected directly in the 3D viewer.
Launch the 3D viewer with the Nervous system activated. Orbit the camera, use the Exploded View slider to separate overlapping pieces, and click individual structures to inspect their FMA reference ID and anatomical metadata.

The brain (FMA50801) is the central organ of the nervous system, comprising 59 modeled sub-structures in this atlas.
Its interconnected regions support perception, movement, memory, language, and bodily regulation.
Together with the spinal cord and peripheral nerves, it carries and processes signals across the body.
Sensory organs detect external stimuli (light, sound, balance) and transmit neural signals via cranial nerves to the brain.
Motor pathways in the brain, spinal cord, and peripheral nerves direct skeletal muscle contraction and coordination.
The hypothalamus links the nervous system to the endocrine system by regulating hormone release from the pituitary gland.
