Key functions of ligaments:
* Joint Stability: Ligaments act like strong ropes, holding bones together and preventing excessive movement or dislocation.
* Limit Range of Motion: Ligaments control the direction and extent of joint movement, ensuring that joints move within their safe limits.
* Proprioception: Ligaments contain sensory receptors that provide information to the brain about joint position and movement. This information helps with balance and coordination.
* Protection: By providing support and stability, ligaments help protect joints from injury.
In summary, ligaments are essential for:
* Maintaining joint stability and integrity.
* Controlling joint movement.
* Providing proprioceptive feedback.
* Protecting joints from injury.
Examples of ligament injuries:
* Sprains: Occur when ligaments are stretched or torn.
* Chronic ligament instability: Can occur when ligaments are repeatedly injured or overstretched.
It's important to note that ligaments don't have a good blood supply, so they can take a long time to heal.
