What is the weakest muscle in the human body?

The human body is equipped with more than 600 muscles that perform various vital functions for its correct functioning; They range from pumping blood throughout the body to allowing you to lift heavy objects. From them, The one that works the hardest is the heart, while the weakest is the skeletal muscle, more precisely the stapedius.

LSkeletal muscles are the most fragile in the human body and are easy to damage due to their small size. The stapedius muscle, also known as the stapedius, is the weakest muscle in the body according to the American Academy of Orthopedic Surgeons.

This qualification applies to muscles who do not work every day and, for this reason, cannot carry out a task for a long time without causing discomfort.

Measures approximately between 1 and 6 millimeters in length, The stapedius muscle is located in the tympanic cavity of the middle ear.which connects the pyramidal eminence of the stony part of the temporal bone to the posterior surface of the neck of the stapes.

Its main function is to protect the auditory system from exposure to loud sounds and help control the amplitude of sound waves from the general external environment to the inner ear.. It is estimated that a healthy adult, without previous hearing problems, should have a sound threshold of approximately 85 decibels.

The heart muscle, responsible for pumping all the blood through the body, can also be considered one of the weakest in the human body, although it is also one of the most vital, since without it the heart could not pump and people could not. They could breathe.

Unlike what happens with skeletal muscle, which is made up of striated cells and tissues, cardiac muscle is made up of other types of tissues responsible for pumping blood.

The cardiac muscle, also known as the myocardium, is also composed of autonomic or cardionector cells, smooth tissues, and white blood cells.

Loss of muscle function

According to the specialized medical portal MedlinePlus, “loss of muscle function occurs when a muscle does not function or move normally.”

“Loss of muscle function after these types of events can be severe; in some cases, muscle strength may not fully recover, even after treatment. Paralysis can be temporary or permanent and can affect a small (localized) area or extensive (generalized) It can affect only one side (unilateral) or both sides (bilateral),” he adds.

Likewise, he explains that it can be caused by several factors:

• A disease of the muscle itself (myopathy)
• A disease of the area where the muscle and nerve meet (neuromuscular junction)
• A disease of the nervous system: nerve damage (neuropathy), spinal cord injury (myelopathy), or brain damage (stroke or other brain injury)
• Alcohol-associated myopathy
• Congenital myopathies (usually due to a genetic disorder)
• Drug-induced myopathy (statins, steroids)
• Dermatomyositis and polymyositis
• Amyotrophic lateral sclerosis (ALS or Lou Gehrig’s disease)
• Bell’s palsy
• Muscular dystrophy
• Botulism
• Guillain Barre syndrome
• Myasthenia gravis or Lambert-Eaton syndrome
• Paralyzing shellfish poisoning
• Periodic paralysis
• Peroneal nerve injury
• Polio or other viruses
• spinal cord injuries
