Anatomy Standard

We are pleased to present newly created deep muscles of the hip. Revealed through internal and external rotation, these layers are rarely seen, yet constantly at work.

Most people recognize the movement.
Few can name what’s actually doing it.

How many of the visible muscles can you identify?

We are pleased to present a new lateral-view animation of the leg in motion.
As the limb moves through extension and flexion, the active muscle groups light up.

Now the challenge: can you name every muscle active in each phase?
Most people miss at least one.

We are pleased to present our newly created quadriceps muscle in motion, demonstrated through leg flexion and extension.

Can you name all four heads of the quadriceps muscle?

Another layer added to our mission to build a complete, functional digital model of the human body.

We’re continuing our work on creating detailed 3D models and animations of the leg muscles.
Today, we’re excited to share our latest animation — the hamstrings and their function in movement.

The hamstring group consists of three muscles:
Biceps femoris
Semitendinosus
Semimembranosus

A huge thank you to Dr. Bertram Zarins, and our community for your continuous support to help make animations like these happen.

🎥 Ever wondered how the meniscus actually moves inside the knee?

With the femur removed, our app gives you a clear, detailed view of the meniscus in motion — something that’s nearly impossible to capture with traditional resources

This unique visualization is one of the best ways to truly understand meniscus function, joint health, and load distribution.

That’s why we built Knee Biomechanics with Dr. Bertram Zarins — the most accurate and interactive tool for exploring the anatomy and biomechanics of the knee.

We’re excited to announce our new app: Knee Biomechanics with Dr. Bertram Zarins 🎉

👉 Available now on https://linktr.ee/anatomystandard

This powerful learning tool brings you:
✅ Highly accurate 3D models of the knee
✅ Interactive motion simulation
✅ Layer-by-layer anatomical exploration
✅ Realistic visualization of ligament tension & joint kinematics
✅ Expert guidance from Dr. Bertram Zarins, ensuring the highest level of anatomical accuracy

Whether you’re a student, healthcare professional, or just fascinated by the human body, this app is an invaluable resource for understanding the anatomy and biomechanics of the knee.
