Appendix. The appendix is perhaps the most widely known vestigial organ in the human body of today. If you’ve never seen one, the appendix is a small, pouch-like tube of tissue that juts off the large intestine where the small and large intestines connect.
What is the coolest muscle in the body?
6 Reasons Why the Diaphragm may be the Coolest Muscle in the Body
- 1) We can contract our diaphragm voluntarily–but it also will contract without us consciously telling it to.
- 2) The diaphragm helps to mobilize the ribs, lumbar spine and thoracic spine.
What is the least used muscle in the human body?
Just about all of them! But our least-used muscles are probably the lumbar multifidus muscles in the lower back. Studies have shown that prolonged slumping in front of the TV can inactivate these muscles. This can lead to back pain, and once inactivated they can take months to recover.

What muscle never stops?
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 masseter muscle?
The masseter is one of the muscles of mastication. It is a powerful superficial quadrangular muscle originating from the zygomatic arch and inserts along the angle and lateral surface of the mandibular ramus. The masseter is primarily responsible for the elevation of the mandible and some protraction of the mandible.
Is the tongue the strongest muscle?
First, the tongue isn’t a single muscle. It’s actually made up of eight different muscles. Second, while very strong and flexible, the tongue cannot lay a valid claim to be the strongest muscle in the human body, regardless of how you define strength.
What body part has no purpose?
Vestigial organs are parts of the body that once had a function but are now more-or-less useless. Probably the most famous example is the appendix, though it is now an open question whether the appendix is really vestigial.

The weakest of all muscle tissues, visceral muscle makes organs contract to move substances through the organ. Because visceral muscle is controlled by the unconscious part of the brain, it is known as involuntary muscle—it cannot be directly controlled by the conscious mind.
What are some of the most interesting muscles in the body?
A fascinating muscle, to me, is the illiopsoas, made of illiacus and psoas major. It runs from the spine to the lesser trochanter of the femur in the groin region, which is odd. This is why a traditional situp, not a crunch, would give people back pain.
What is the smallest muscle in the human body?
The smallest muscle in the body is located inside the ear. It’s called the stapedius, and it’s less than 2 millimeters long, according to Guinness World Records. Its job is to support the smallest bone in the body, called the stapes, which is part of the middle ear and helps conduct vibrations to the inner ear.
What is the longest muscle in the human body?
The longest muscle in the body is the sartorius muscle, which runs diagonally down the thigh. It stretches from the outer side of the hip bone down to the inside of the knee bone. The sartorius can be up to 23 inches (60 centimeters) in length, according to a 2005 paper.
