Avicenna stated in his Canon that tuberculosis is contagious, that disease can spread through water and soil, that emotions affect physical well - being, and that nerves transmit both pain and impulses for muscle contraction.
Avicenna Kanonā rakstīja, ka tuberkuloze ir lipīga, ka slimības var izplatīties ar augsnes un ūdens starpniecību, ka emocijas ietekmē fizisko stāvokli un ka nervi vada gan sāpju sajūtu, gan impulsus, kuri liek muskuļiem sarauties.
