Nail course – Orthopedics
A healthy foot is made up of a longitudinal and transverse arch running alongside which protects the sole and provides „springs” while walking.
1. Longitudinal arch
a) Its role:
It protects the soft parts of the middle of the sole (blood vessels, nerves, muscles) from being compressed. These blood vessels, nerves, muscles run under the sole, if they subside walking will cause pain.
2. Transversal arch
- Its situation:
Between the tuberosity surface of calcaneum and the head of metatarsal bones.
- It has 5 arches:
– internal arch I.
– external arch II.
– the II. one is the longest and the highest arch
– its highest bone is around the II. joint of tarsal-metatarsal bone
- Its role:
It protects the soft parts of the middle of tsole from being compressed.
The leg becomes more weight-bearing.
It reduces shaking while walking or jumping, it makes walking more even and flexible.
