Tetanus typically affects the muscles of the jaw and throat first. According to the reference provided, the Clostridium tetani bacteria produces a toxin that interferes with nerve function. This interference leads to involuntary muscle contractions and painful spasms. The muscles of the jaw and throat are most commonly the initial site of these spasms. This is why tetanus is often called "lockjaw."
In summary:

| Initial Body Part | Jaw and throat muscles |
| Cause | Tetanus toxin interfering with nerve function |
