The scalp is innervated by a network of nerves that provide sensory perception. The main nerves of the scalp, as outlined by the reference, include the following:
Major Scalp Nerves
| Nerve | Location | Function |
|---|---|---|
| Supratrochlear Nerve | Forehead and inner eye area | Sensation in the forehead |
| Supraorbital Nerve | Forehead and upper eyelid | Sensation in the forehead and upper eyelid |
| Zygomaticotemporal Nerve | Temples and lateral forehead | Sensation in the temporal area |
| Auriculotemporal Nerve | Temples and ear area | Sensation around the ear and temple |
| Lesser Occipital Nerve | Back and side of the scalp | Sensation in the occipital region |
| Greater Occipital Nerve | Back of the scalp, from the neck up | Sensation at the back of the head |
Specific Nerve Functions:
- Sensory Perception: These nerves primarily function to provide sensory input to the scalp, allowing you to feel touch, pressure, pain, and temperature.
- Regional Innervation: Each nerve innervates a specific area of the scalp. Understanding these locations is essential for procedures involving the scalp.
Clinical Significance:
Understanding the precise location and function of these nerves is crucial for:
- Anesthesia: Local anesthesia in the scalp requires knowledge of nerve locations for effective blocking during procedures.
- Nerve Blocks: Procedures, such as nerve blocks, rely on these anatomical landmarks for pain management.
- Diagnostics: Nerve damage or irritation can cause specific patterns of pain or altered sensation, which can aid in diagnosis.
The reference also mentions the corresponding arteries like the supratrochlear and supraorbital arteries, alongside the zygomaticotemporal artery. The nerves, arteries, and their respective functions and locations are critical to know when dealing with this region of the head.
