3 Mechanisms That Make Muscles Grow. Underlying all progression of natural muscle growth is the ability to continually put more stress on the muscles. This stress is a major component involved in the growth of a muscle and disrupts homeostasis within your body.

The human body is comprised of hundreds of muscles, about 640 in total. There is no exact count largely because expert opinions are conflicted regarding what constitutes a distinct muscle. Therefore, some experts will suggest 639 total while others may suggest there are more.

THE MUSCULAR SYSTEMSkeletal, Smooth and Cardiac Muscles After reading one of the Body Systems-Go take a Quiz! There are more than 639 skeletal muscles in your body. Some sources will say 640 muscles in the human body. On average, your body weight is 40% muscle. Out of the 639/640 muscles, 30 of them are facial muscles, which help you create all those different faces of happiness, surprise, joy, sorrow, sadness, fright, etc. The muscles surrounding your eye are the busiest muscles in your body.

In one of the most interesting studies in the past 5 years, researchers showed that those who were “extreme responders” to muscle growth, with an incredible 58% myofiber hypertrophy from an exercise, had 23% activation of their satellite cells.

While the exact number in the human body may not be known, what is known is that muscles are categorized as one of three different types: striated, smooth, and cardiac. Striated muscles, also called voluntary or skeletal muscles, are those the body has conscious control of.

When activated, they help to add more nuclie to the muscle cells and therefore contribute directly to the growth of myofibrils (muscle cells). Activating these satellite cells may be the difference between what allows certain “genetic freaks” to grow massive muscles and what makes other people “hard-gainers.

And the biggest muscle in your body is the gluteus maximus (your butt). Each muscle belongs to one of three categories: skeletal muscles, which move bones-smooth muscles, which control involuntary movements such as breathing and digestion, - and cardiac muscle, which is found in the heart.

Muscles of the human body. The body has three types of muscles: smooth, skeletal and cardiac. Skeletal muscles are directly connected to the bones and enable body movements. The smallest muscle in the human body is located deep in the ear.

­When most people think of muscles, they think about the muscles that we can see. For example, most of us know about the biceps muscles in our arms. But there are three unique kinds of muscle in any mammal's body: 1  Skeletal muscle is the type of muscle that we can see and feel. 2  When a body builder works out to increase muscle mass, skeletal muscle is what is being exercised.

The Physiology Of Muscle Growth. After you workout, your body repairs or replaces damaged muscle fibers through a cellular process where it fuses muscle fibers together to form new muscle protein strands or myofibrils. These repaired myofibrils increase in thickness and number to create muscle hypertrophy (growth). Muscle growth occurs whenever the rate of muscle protein synthesis is greater than the rate of muscle protein breakdown. This adaption, however, does not happen while you actually lift the weights.
