The definition of stammer is to stutter or to speak with involuntary pauses and often where the first sound of each word is repeated. When you are feeling really shy and intimidated and you can't get words out and so you say I th... th... th... think, this is an example of a time when you stammer.
For other uses, see Shiver (disambiguation) . Shivering (also called rigors or shuddering) is a bodily function in response to early hypothermia or just feeling cold in warm-blooded animals. When the core body temperature drops, the shivering reflex is triggered to maintain homeostasis. Skeletal muscles around begin to shake in small movements, creating warmth by expending energy. Shivering can also be a response to a fever, as a person may feel cold. During fever the hypothalamic set point for temperature is raised. The increased set point causes the body temperature to rise (pyrexia), but also makes the patient feel cold until the new set point is reached. Rigor occurs because the patient's body is effectively shivering in a physiological attempt to increase body temperature to the new set point.
