muscle-types

 

You may not spend too much of your day worrying about muscle tissue but it is hugely important in your life and it has four main tasks to do. The first is to be able to respond to any stimulation that impacts on your body, and this is referred to as excitability.

 

The next thing that muscle tissue has to be able to do is to contract, which is referred to as contractibility. It also needs to be able to be stretched without fear of it being torn, which is referred to as extensibility and there is a need for the muscle tissue to be able to return to its normal shape and position after it has been stretched, which is referred to as elasticity.

 

There are three main types of muscle tissue, which are:

  • Skeletal muscle
  • Smooth muscle
  • Cardiac muscle

 

Skeletal muscle is connected to the bone by tendons and it is crucial in maintaining a person’s posture and managing their movement. The average male is said to be made up of over 40% skeletal muscle.

 

Smooth muscle is located within the lining walls of the body’s organs or key structures. This means that smooth muscle, which is not placed under level of conscious control, is found in areas like the bladder, the uterus, stomach, esophagus, urethra and other parts.

 

Cardiac muscle is another involuntary muscle but it acts closer to the way that skeletal muscle performs and it is only located at the heart.

 

There are other muscle types and elements in the body

There are also other types of muscle tissue which are found in the body including fascia, Myoglobin & Mitochondria and there are also the Type I fibres, Type II A fibres and Type II B fibres, which come under the skeletal muscle category. These fibres react and interact in different ways and also perform different tasks in the body. The Type II B fibres are said to react faster and more effectively than the Type I fibres but they all play a role in keeping people active and on the go.

 

The Type I fibres are packed with capillaries and the fact that they are very rich in Myoglobin & Mitochondria is what gives muscle tissue that instantly recognisable red colour. This is very important for your health because these fibres provide the ability to carry a lot of oxygen and help people to maintain aerobic exercise for long periods of time.

 

Type II A fibres also help to boost the aerobic process and again, is referred to as a slow muscle. This is where it contrasts with Type II B fibre as this is referred to as the fastest type of muscle that is found in the human body. This muscle is able to contract very quickly and with a higher amount of force. However, this fibre can only perform in this way for a short period of time before the process starts to hurt. This is the sensation that is sometimes mistakenly referred to as a building-up of lactic acid.
