In vertebrates, skeletal muscle contractions are neurogenic as they require synaptic input from motor neurons to produce muscle contractions. A single motor neuron is able to innervate multiple muscle fibers, thereby causing the fibers to contract at the same time.

Osteomyelitis (OM) is infection and inflammation of the bone and bone marrow. It can be usefully subclassified on the basis of the causative organism (pyogenic bacteria or mycobacteria) and the route, duration and anatomic location of the infection. Osteomyelitis usually begins as an acute infection, but it may evolve into a chronic condition. The word is from Greek words á½ÏÏÎ­Î¿Î½ osteon, meaning bone, Î¼ÏÎµÎ»Ï- myelo- meaning marrow, and -á¿ÏÎ¹Ï -itis meaning inflammation.
