Sharp stabbing pain is carried by which type of fibers –

**Core Concept**
Sharp stabbing pain is transmitted through a specific type of nerve fiber that is responsible for transmitting high-threshold, rapid, and intense pain signals. This type of pain is often associated with injury or damage to tissues.

**Why the Correct Answer is Right**
The correct answer is A, A-delta fibers, which are fast, myelinated nerve fibers that transmit sharp, stabbing, or burning pain. These fibers have a conduction velocity of up to 30 meters per second and are responsible for transmitting pain signals from the peripheral nervous system to the central nervous system. A-delta fibers are activated by high-intensity stimuli, such as cutting or pinching, and are responsible for the initial, sharp pain associated with injury.

**Why Each Wrong Option is Incorrect**
**Option B:** C-fibers are unmyelinated nerve fibers that transmit slow, burning, or aching pain, which is not characteristic of sharp stabbing pain.
**Option C:** A-beta fibers are large, myelinated nerve fibers that transmit touch and pressure sensations, not pain.
**Option D:** A-gamma fibers are small, myelinated nerve fibers that transmit motor signals to muscles, not pain.

**Clinical Pearl / High-Yield Fact**
Remember that A-delta fibers are responsible for the initial, sharp pain associated with injury, whereas C-fibers transmit slow, burning pain.

**Correct Answer: A. A-delta fibers**
