6 curiosities about our knees

1.A fundamental hinge

Our knees intervene in the movement.If we had x-ray vision, we would see that the knee is a kind of hinge that allows the movement of flexion of the legs: that gives the possibility to sit, kneel, stop, and any other activity that comes to mind.

2.Bones and cartilages

This incredible and great articulation-as we already mentioned, the biggest nde of our body-is formed by muscles and ligaments, bones and cartilage.

The lower part of the femur (upper leg bone) rotates above the upper end of the tibia (bone that goes down), and in the center and in front of this convergence there is a smaller bone structure, which is vital: the label , which glides smoothly with each movement.muscles.

All this is covered by a structure called cartilage , which is an elastic substance that is responsible for absorbing external impacts and allowing flexibility in movements.

There is also a connective tissue- the menisci -, which function as a kind of mattress, and which serve to resist body weight and give stability to our knees.

3.Ligaments and muscles

Ligaments are something like elastic bands that help cartilage in their mission tiva; for them, the articulation of the knees becomes a very powerful motor center, very flexible, that regulates the movements back and forth, and prevents the rotation can be very fast.

Knee ligaments

As for the muscles, we have two large muscular structures, the quadriceps , which are the muscles of the front of the thighs, which join the patella, and the hamstrings , which are attached to the tibia through ligaments.

This set of ligaments and muscles is what makes up the traction force , they are the ones that push the system and allow the legs to move.

4.Impressive movement

Here comes the extraordinary hinge that are our knees, which do everything without us noticing. To flex , l The ligaments of the hamstrings push the tibia back, and so the knee bends.At the same time, the soft structures (cartilage and ligaments) protect and stabilize the joint.

To stretch the leg, it is the quadriceps that push the movement , which falls on the label and forces the knee to extend.The elastic parts are important in these movements, because lubricate, support, strengthen and give flexibility to the entire joint .

The wonder that our body means is incredible.Did you know that the longest nerve we have is the sciatic nerve ? Coincidentally, it starts at the base of the spinal cord and reaches our knees.

Hence it is so important to maintain the health of this joint.

6.Absorb all impacts

That's right, as responsible for weight support.That is why it is a very delicate area, despite its incredible strength.Our knees suffer from daily activity and sports that we decide to practice.One of those who least harm them does is swimming, and the Yoga helps strengthen both muscles and tendons, protecting the bones of the knees.
