Your heart is made of cardiac muscle. This type of muscle only exists in your heart. Unlike other types of muscle, cardiac muscle never gets tired. It works automatically and constantly without ever pausing to rest.

What is the most neglected muscle?

Glute Muscles

Perhaps the most neglected muscle group in the body, the Glutes are also one of the most important muscle groups for proper biomechanics and optimal sports performance. They're also connected to your spine, so weak Glutes muscles can lead to back pain and injury.

What is the laziest muscle in the body?

“Glutes” are possibly the laziest muscles we have, so we need to make them a priority in our training or we face ongoing injuries. The laziest of the gluteal muscle trio is gluteus medius (or “glute mede”). The glute mede runs from the top ridge at the back of the pelvis to the hip.

What is the weakest muscle?

The Stapedius, the smallest skeletal muscle in the human body, which is about 1 mm in length, is regarded to be the weakest muscle. It originates from a prominence known as the pyramidal eminence at the posterior edge of the tympanic cavity. It inserts into the stapes' neck.

What is the most undiscovered organ?

The liver has a unique capacity among organs to regenerate itself after damage. A liver can regrow to a normal size even after up to 90% of it has been removed. But the liver isn't invincible. Many diseases and exposures can harm it beyond the point of repair.

What part of the body is most sensitive to pain?

Our forehead and fingertips are the most sensitive to pain, suggests research that used lasers to give volunteers sharp shocks across their body. The study was the first to look at how our ability to work out where something hurts – called “spatial acuity” – varies across the body.

Where is the body most sensitive to pain?

The forehead and fingertips are the most sensitive parts to pain, according to the first map created by scientists of how the ability to feel pain varies across the human body.

Does the brain itself feel pain?

Your brain also has the unfortunate ability to fabricate a sensation of pain when no nociceptors are active. To explain what I mean by this, it's crucial to understand that “pain” (the feeling) doesn't always result from “this feels bad” (the signal).
