Final answer:
Muscle spasms in the face, neck, tongue, and back/neck muscles can be caused by conditions such as cervical dystonia and tetanus. Cervical dystonia involves involuntary muscle contractions in the neck, leading to abnormal head positioning and movements. Tetanus is a bacterial infection that can cause lockjaw and uncontrollable spasms in various muscles.
Step-by-step explanation:
Muscle spasms in the face, neck, tongue, and back/neck muscles can be caused by various conditions. In the context of the provided information, two conditions are mentioned: cervical dystonia and tetanus. Cervical dystonia is a rare condition where the muscles in the neck contract involuntarily, causing abnormal head positioning and movements.
Tetanus, on the other hand, is a serious condition caused by a bacterial infection. It can lead to muscle spasms starting in the jaw muscles, resulting in lockjaw. As the infection progresses, uncontrollable spasms can occur in the muscles of the neck, back, and legs, causing a rigid posture and difficulty breathing.
It is important to consult a healthcare professional for a proper diagnosis and treatment if experiencing muscle spasms in these areas.
