The human body is made up of an extensive system of tissue, strength and mobility, with over 600 muscles located almost everywhere throughout the body. The exact number of muscles is not straightforward, with some experts saying the body has close to 600 muscles and others saying it may be as many as 840. This discrepancy exists because anatomists have different ways of deciding whether a muscle is one muscle with multiple parts or multiple distinct muscles.
| Characteristics | Values |
|---|---|
| Number of muscles | Between 600 and 840 |
| Types of muscle | Skeletal, smooth, cardiac |
| Functions | Moving food through the digestive tract, pumping blood, supporting movement, lifting heavy weights, giving birth |
| Involuntary/voluntary | Smooth and cardiac muscles are involuntary; skeletal muscles are voluntary |

What You'll Learn
The human body has over 600 muscles
There are three main types of muscle: skeletal, smooth, and cardiac. Skeletal muscles are those that can be controlled by conscious thought, while smooth muscles are responsible for functions such as squeezing and squishing stuff in tubes, and the cardiac muscle is responsible for pumping blood.
The smallest muscle in the body is the stapedius muscle, located within the middle ear, while the largest is the gluteus maximus, which helps with the rotation of the thigh and hip joint.
The neuromuscular system is made up of the brain, nerves, and skeletal muscles working together to cause movement. To function properly, muscles need fuel in the form of glucose from carbohydrates, as well as particular minerals, electrolytes, and other dietary substances such as calcium, magnesium, potassium, and sodium.

There are over 650 named skeletal muscles
The number of muscles in the human body is a surprisingly difficult question to answer. This is because it depends on how you count and what you include and exclude. For example, there are about 400 muscles that only specialists care about. There is also just one important cardiac muscle.
There are also countless smooth muscles, which do the work of the autonomic nervous system, mostly squeezing and squishing stuff in tubes. On a cellular level, you can have billions of smooth muscle cells.
When most people ask how many muscles are in the human body, they mean the serious bone-movers, such as pecs, delts, lats, traps, glutes, biceps and triceps. There are maybe another hundred muscles if you include the fiddly little muscles of the hands and feet, and the major face muscles.

Smooth muscle occurs on a cellular level
The human body has an estimated 600 to 840 muscles, although some sources state that there are over 650 named skeletal muscles. Smooth muscle occurs on a cellular level, with billions of smooth muscle cells in the body. These muscles are part of the autonomic nervous system, and are responsible for functions such as squeezing and squishing stuff in tubes, facilitating movement, moving food through the digestive tract, and allowing the heart to pump blood.

Muscles support almost every part of the body
The human body has between 600 and 840 muscles, depending on how they are counted. Some experts say the body has close to 600 muscles, while others say it may be as many as 840. This discrepancy exists because anatomists have different ways of deciding whether a muscle is one muscle with multiple parts or if it should be considered multiple distinct muscles.
There are about 700 named skeletal muscles in the human body, including roughly 400 that only specialists care about. There is just one important cardiac muscle. There are also countless smooth muscles, which do the work of the autonomic nervous system, mostly squeezing and squishing stuff in tubes.
The muscles of the body perform a variety of vital functions, including facilitating movement, moving food through the digestive tract, and working to allow the heart to pump blood. They also help with more minor tasks, such as lifting a heavy backpack.
Most people are only interested in knowing about 200 to 300 muscles, the "serious bone-movers" such as pecs, delts, lats, traps, glutes, biceps and triceps. However, there are maybe another hundred muscles if you include the fiddly little muscles of the hands and feet, and the major face muscles.

Muscles are responsible for a variety of vital functions
The human body has around 600 muscles, although some estimates place the number as high as 840. These muscles are responsible for a variety of vital functions, from pumping blood around the body to lifting heavy objects. There are about 700 named skeletal muscles, including around 400 that only specialists care about. There is only one important cardiac muscle. There are also countless smooth muscles, which do the work of the autonomic nervous system, mostly squeezing and squishing stuff in tubes.
The muscles of the body perform a variety of vital functions. For example, they facilitate movement, move food through the digestive tract, and allow the heart to pump blood. They also help with balance and posture, and enable us to perform complex physical tasks such as playing sports or dancing.
The number of muscles in the body is difficult to pin down for a few reasons. Firstly, there are different types of muscles, and it's not always clear what should be included in the count. Secondly, anatomists have different ways of deciding whether a given muscle is one muscle with multiple parts or if it should be considered multiple distinct muscles.
Despite the ambiguity around the exact number, it's clear that muscles play a crucial role in our bodies, enabling us to perform a wide range of physical activities and maintain our health.
