Body Parts You’ve Never Heard Of

The video explores three lesser-known body parts: the fabela, auricular muscles, and lacrimal puncta. The fabela is a small bone near the knee that can cause pain. Auricular muscles, once used for ear movement, may help operate assistive devices. Lacrimal puncta are tiny eye holes that drain tears, and blockages can cause watery eyes. These parts, though obscure, significantly impact our lives.

What is the primary suspected function of the fabela?

• To support the tibia

• To stabilize a bony protrusion at the end of the femur

• To increase blood flow to the knee

• To enhance knee flexibility

What percentage of people can wiggle their ears using auricular muscles?

• 10%

• 30%

• 40%

• 20%

Why might auricular muscles be useful for assistive devices?

• They are not affected by spinal cord injuries

• They are strong and can lift heavy objects

• They can detect sound frequencies

• They are connected to the brain directly

What is the role of the lacrimal puncta in the eye?

• To drain tears into the nasal cavity

• To enhance vision clarity

• To produce tears

• To protect the eye from dust

What can cause a blockage in the lacrimal puncta?

• Lack of sleep

• High salt intake

• Infection or medication

• Excessive blinking
