Which is the strongest bone in human body?

Is the heart one muscle?

Smooth muscles react more slowly and tire more slowly than skeletal muscles.

How do muscles grow biology?

Muscle hypertrophy occurs when the fibers of the muscles sustain damage or injury. The body repairs damaged fibers by fusing them, which increases the mass and size of the muscles. Certain hormones, including testosterone, human growth hormone, and insulin growth factor, also play a role in muscle growth and repair.

What is the structure and function of cardiac muscle?

Cardiac muscle tissue works to keep your heart pumping through involuntary movements. This is one feature that differentiates it from skeletal muscle tissue, which you can control. It does this through specialized cells called pacemaker cells. These control the contractions of your heart.

What is muscle in human body?

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. However dexterous it may be though, its power does not match that of muscles such as the soleus.
