Key Takeaways
- Tissues require structural directionality for proper operation.
- Cells must determine orientation during development.
- Misalignment can cause developmental failures.
Biological tissues rely on precise directional organization to function correctly, from sensory structures in the ear to tiny hairs on limbs. During embryonic growth, individual cells actively determine their orientation and align themselves with neighboring units. Failures in this synchronized alignment process can lead to severe developmental defects and organ malfunction.
