By Mayo Clinic Staff. A febrile seizure is a convulsion in a child that may be caused by a spike in body temperature, often from an infection. Your child's having a febrile seizure can be alarming, and the few minutes it lasts can seem like an eternity. Febrile seizures represent a unique response of a child's brain to fever, usually the first day of a fever. Fortunately, they're usually harmless and typically don't indicate an ongoing problem. You can help by keeping your child safe during a febrile seizure and by comforting him or her afterward.

They supply some of the muscles of the neck, back and the diaphragm. After arising from the cervical plexus, the muscular branches tend to travel initially in an anteromedial direction.
