Verified step by step guidance

Begin by understanding the concept of force summation in muscle tissues. Force summation refers to the process by which muscles increase the force of contraction by increasing the frequency of stimulation or by recruiting more muscle fibers.

Identify the types of muscle tissues in the human body. There are three primary types: skeletal muscle, cardiac muscle, and smooth muscle. Each type has distinct characteristics and functions.

Skeletal muscle is responsible for voluntary movements and is attached to bones. It is characterized by a striated appearance and is under conscious control.

Cardiac muscle is found in the heart and is responsible for pumping blood throughout the body. It is also striated but operates involuntarily, meaning it functions without conscious control.

Smooth muscle is found in the walls of hollow organs such as the intestines and blood vessels. It is non-striated and also operates involuntarily, helping to move substances through the body.
