The palmaris longus is a muscle visible as a small tendon located between the flexor carpi radialis and the flexor carpi ulnaris, although it is not always present. It is absent in about 14 percent of the population; this number can vary in African, Asian, and Native American populations, however.
1. OCCIPITALIS MINOR. This thin banded muscle located just under the back of your skull allows you to move your scalp slightly. That's not a move that's in great evolutionary demand these days, so it's unsurprising that it's managed to disappear completely in some populations.
The prevalence of the palmaris longus (PL) muscle varies more than any other muscle in the human body. Its absence across the world ranges between 1.5% and 63.9%.
Levator submandibuli muscle (Banjo muscle) a rare muscle in human beings; anatomy, morphogenesis, function and incidence.
Poland syndrome is a disorder in which affected individuals are born with missing or underdeveloped muscles on one side of the body, resulting in abnormalities that can affect the chest, shoulder, arm, and hand. The extent and severity of the abnormalities vary among affected individuals.
Rhabdomyolysis is a rare muscle injury where your muscles break down. This is a life-threatening condition that can happen after an injury or excessive exercise without rest.
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.
Auricular Muscles
Located around the human ear, these vestigial muscles are responsible only for ear wiggling.
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.
The strongest muscle based on its weight is the masseter. With all muscles of the jaw working together it can close the teeth with a force as great as 55 pounds (25 kilograms) on the incisors or 200 pounds (90.7 kilograms) on the molars.
A person's ability to put on muscle mass is limited by their genetics. Through proper training, good nutrition and adequate rest, a person can maximize their genetic potential, but they cannot exceed their genetic limitations.
Final Answer: Hence, The muscles which never fatigue are the Cardiac muscles.
There are about 600 muscles in the human body. The three main types of muscle include skeletal, smooth and cardiac. The brain, nerves and skeletal muscles work together to cause movement – this is collectively known as the neuromuscular system.
Stapedius muscle is termed to be the smallest skeletal muscle in human body, which has a major role in otology. Stapedius muscle is one of the intratympanic muscles for the regulation of sound.
Skeletal muscle is a highly heritable quantitative trait, with heritability estimates ranging 30–85% for muscle strength and 50–80% for lean mass.
Second strongest muscle: Masseter is the second strongest muscle in the human body.
You may actually be sitting on your largest muscle at this very moment. The largest muscle in the body is the gluteus maximus, also known as your buttocks or glutes. In terms of the largest average muscle size, the glutes are followed closely by the quadriceps, lats, hamstrings, and pectoral muscles.
Abstract. The sartorius muscle is the longest muscle in the human body. It is strap-like, up to 600 mm in length, and contains five to seven neurovascular compartments, each with a neuromuscular endplate zone. Some of its fibers terminate intrafascicularly, whereas others may run the full length of the muscle.
As the refractory period of cardiac muscle is high, it does not get fatigued. Therefore, cardiac muscles work all the time throughout life without undergoing fatigue.
The appendix may be the most commonly known useless organ.
Many years ago, the appendix may have helped people digest plants that were rich in cellulose, Gizmodo reported. While plant-eating vertebrates still rely on their appendix to help process plants, the organ is not part of the human digestive system.
Involuntary muscles exhibit slow and rhythmic movement. These muscles do not experience fatigue and work without stopping. These muscles are essential for all body movement and its locomotion.
A good lean muscle percentage range should be about 70% to 90% to be considered healthy. That means your body fat percentage ranges from 10-30%. Athletes typically range in the 7-22% body fat for maximum performance. Men tend to be on the higher side with lean mass in 80-90% range and woman in the 70-85% range.

Without a doubt, the title of biggest bodybuilder on this list goes to Greg Kovacs. This monster of a man didn't just have an insane amount of mass - he was also very tall. Greg Kovacs was 6'4" and towered over the majority of bodybuilders who stood around the 6'0" mark or shorter.
