FMA544501 3D mesh
Left eye
Composite organ of vision in the left orbit comprising 23 modeled ocular and accessory components in the reference atlas.
These structures contribute to special senses, including sight, hearing, and balance. Their specialized tissues detect stimuli and work with the nervous system to convey information.
The BodyParts3D reference dataset models 45 sensory pieces across 42 FMA concepts, primarily featuring detailed bilateral ocular anatomy (cornea, iris, lens, sclera, choroid, lacrimal apparatus) and the external ear.
Detects external physical stimuli supporting sight, hearing, and equilibrium.
Focuses incoming light through transparent ocular media (cornea and lens) onto photosensitive tissues.
Collects and channels sound waves through the external ear structures.
Works directly with cranial nerves and central nervous pathways to convey sensory information to the brain.

Composite organ of vision in the left orbit comprising 23 modeled ocular and accessory components in the reference atlas.
The transparent anterior segment of the fibrous tunic of the eyeball that refracts light entering the eye.
The contractile pigmented diaphragm of the eye located anterior to the lens, regulating the size of the pupil and the amount of light reaching the retina.
A transparent biconvex structure suspended behind the iris that adjusts its curvature to focus light onto the back of the eye.
The tough, opaque outer fibrous coat of the eyeball that maintains ocular shape and provides attachment for extraocular muscles.
The outer anatomical structure of the auditory system that collects sound waves and directs them toward the external acoustic meatus.
Every anatomical structure assigned to the Sensory organs layer in atlas.json. Curated landmarks include a Learn more guide, and all 42 structures can be selected directly in the 3D viewer.
Launch the 3D viewer with the Sensory organs 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.
You have not selected any structures in the Sensory organs inside the 3D viewer yet during this session. Click Explore in 3D or any structure card above to inspect a structure on the 3D model.
Sensory organs contribute to special senses including sight, hearing, and balance.
Specialized sensory tissues detect stimuli and partner with the nervous system to convey information.
The 3D atlas includes detailed sub-structures of the left and right eyes (cornea, iris, lens, choroid, sclera) and the external ear.
Sensory organs transduce physical stimuli into neural signals carried by cranial nerves (such as the optic chiasm and oculomotor nerves) to the brain.
Extraocular muscles (rectus and oblique muscles) attach to the sclera to precisely rotate and align the eyeballs.
The bony orbits and temporal bones of the skull house and protect the delicate structures of sight, hearing, and balance.
