As you move away from the bulb, you see a quarter of the light every time the distance is doubled. A laser gives light in one small beam. If it gets into the eye, you receive all the laser's energy, not just a fraction. Third, a light bulb gives off light at many different wavelengths (different photon energies). A laser is a pure tone, only one wavelength. The coherent light will be more damaging. The common red laser pointer is a diode laser, really just a special type of transistor, or diode. Because of the unique features of laser light, it is magnified by 100,000 times as it passes through the eye.
In human anatomy, the ulnar nerve is a nerve that runs near the ulna bone. The ulnar collateral ligament of elbow joint is in relation with the ulnar nerve. The nerve is the largest unprotected nerve in the human body, so injury is common. This nerve is directly connected to the little finger, and the adjacent half of the ring finger, innervating the palmar aspect of these fingers, including both front and back of the tips, perhaps as far back as the fingernail beds. This nerve can cause an elec
The ulnar nerve travels from the shoulder, down the arm and into the hand. It controls the movement and sensations for parts of the hand (specifically, the fourth and fifth fingers, the palm, and the inside portion of the forearm.) The ulnar nerve can be compressed as it passes through the elbow or wrist. However, the elbow is the most vulnerable point because the ulnar nerve is near the surface and travels through a small space (called the cubital tunnel) within the elbow.
