Development of the immune response

Immune response systemWhen our immune system defends itself from pathogens, both the specific and nonspecific immune systems take part in the development of the immune response.

The development of the immune response begins when trained cells of the immune system identify the foreign body: this identification is achieved thanks to the extraneous surface structure of the intruder, for example a bacterium. The structure of the surface is made up, among other things, of special proteins, antigens.

Certain cells of the specific immune system, B lymphocytes, can create specific proteins “antibodies” to fight against these antigens that are fitted as a key to their lock. A protein that has characteristic of an antibody, are the so-called “immunoglobulins”.

What is tarsal tunnel syndrome?

Tarsal tunnel syndrome causes Tarsal tunnel syndrome is damage to the tibial nerve (tibial nerve) in the area of the ankle. The tunnel is formed by the inner ankle of the foot with a tight band. The tibial nerve  controls the foot soles muscles and the muscles of the lower leg, which is responsible for flexion of the leg.

Furthermore, all perceptions in the area of the lower leg, the heel and the sole of the foot are guided through the nerve to the central nervous system. When the nerve in the tarsal tunnel is irritated by permanent pressure, the tarsal tunnel syndrome occurs. Foot and lower leg are mainly affected.
