3D model
Spine & posture
Cervical Spine: Atlas, Axis & Motion Segments
A separate cervical assembly preserves the different shape of C1, the dens of C2, and the lower cervical vertebrae. Compare this model with the lumbar spine using the linked atlas.
Clinical topic
Neurorehabilitation
Descending Motor Pathways & Post-Stroke Neuroplasticity
Trace bilateral corticospinal teaching pathways and compare them with cortical, capsular and brainstem source structures.
Structured course
Spine & posture
Functional Biomechanics of the Spine & Posture
Compare cervical and lumbar vertebrae, discs and neural relations through five labeled model-derived views.
Clinical topic
Lower limb
Knee Joint Load Transfer & Meniscal Mechanics
Explore the anterior and posterior knee and an exposed tibial plateau with labeled menisci and cruciate ligaments.
2D atlas
Lower limb
Knee Menisci & Ligament Anatomy Atlas
Explore the anterior and posterior knee and an exposed tibial plateau with labeled menisci and cruciate ligaments.
Structured course
Lower limb
Lower Limb Load Transfer & Knee Rehabilitation
Explore the anterior and posterior knee and an exposed tibial plateau with labeled menisci and cruciate ligaments.
3D model
Spine & posture
Lumbar Spine, Discs & Deep Stabilizers
Explore five lumbar vertebrae, the sacrum, intervertebral discs, cauda equina and deep posterior muscles. Bone and disc surfaces come from BodyParts3D; multifidus and the disc nucleus are teaching overlays. Hide bone to inspect internal anatomy.
2D atlas
Neurorehabilitation
Motor Pathways & Brainstem Anatomy Atlas
Trace bilateral corticospinal teaching pathways and compare them with cortical, capsular and brainstem source structures.
3D model
Neurorehabilitation
Motor Pathways: Cortex to Cervical Cord
BodyParts3D cortical, capsular and brainstem structures with an authored bilateral corticospinal pathway overlay. The trajectories illustrate the sequence and crossing; they are not diffusion tractography, a complete connectome, or a prediction of stroke recovery.
3D model
Lower limb
Right Knee: Menisci, Cruciate & Collateral Ligaments
Detailed source bone surfaces with individually selectable teaching reconstructions of the menisci and ligaments. Bone shafts are cropped for joint detail. Hide the femur and patella for a superior view of the tibial plateau. Soft-tissue overlays are illustrative, not measurement-grade.
3D model
Upper limb
Right Shoulder: Rotator Cuff & Scapular Muscles
Inspect the four rotator cuff muscles with the scapula, clavicle, humerus, deltoid, serratus anterior and trapezius. Source meshes retain their anatomical alignment. Superficial muscles start hidden so the cuff is visible.
2D atlas
Upper limb
Rotator Cuff & Scapular Anatomy Atlas
Identify the four rotator cuff muscles and their bony landmarks, then reveal selected scapular and superficial muscles.
Clinical topic
Upper limb
Rotator Cuff Dynamics & Scapular Dyskinesis
Identify the four rotator cuff muscles and their bony landmarks, then reveal selected scapular and superficial muscles.
