Unlike skeletal muscle, smooth muscle is capable of maintaining tone for extended periods and often contracts involuntarily. At a cellular level, smooth muscle can be described as an involuntary, non-striated muscle.
Final Answer: The muscular tissue which functions throughout life continuously without fatigue is the Cardiac 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 walls of heart are made up of cardiac muscles which are capable of contracting and relaxing continuously without getting tired.
Final answer: The muscle which works throughout life without undergoing fatigue is the cardiac muscle.
Cardiac muscle is highly resistant to fatigue due to the presence of a large number of mitochondria, myoglobin and a good blood supply allowing continuous aerobic metabolism.
This is primarily because the heart is made of cardiac muscle, consisting of special cells called cardiomyocytes. Unlike other muscle cells in the body, cardiomyocytes are highly resistant to fatigue.
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.

Glutes and Hips
The glutes and hips are some of the most common weak muscles.
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.
When it comes to versatility, perhaps the tongue is the strongest muscle. Its combination of elasticity and forcefulness gives us the ability to speak, eat and kiss – all things very desirable on a first date.
Smooth muscles
These muscles work automatically, with a person being unaware that they are using them. Unlike skeletal muscles, they do not depend on conscious thought. Many different bodily movements depend on smooth muscle contractions.
Second strongest muscle: Masseter is the second strongest muscle in the human body.

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.
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%.
Heart is the only organ in the body which never rest throughout the entire life. The heart is a hollow muscle that pumps blood throughout the blood vessels by repeated, rhythmic contractions. It is found in all animals with a circulatory system (including all vertebrates).
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.
Fast-twitch muscle fibers provide bigger and more powerful forces, but for shorter durations and fatigue quickly. They are more anaerobic with less blood supply, hence they are sometimes referred to as white fibers or type II.
