Figure 1. (a) Cardiac muscle cells have myofibrils composed of myofilaments arranged in sarcomeres, T tubules to transmit the impulse from the sarcolemma to the interior of the cell, numerous mitochondria for energy, and intercalated discs that are found at the junction of different cardiac musc...
The back contains the origins of many of the muscles that are involved in the movement of the neck and shoulders. In addition, the axial skeleton that runs vertically through the back protects the spinal cord, which innervates almost all the muscles in the body. Multiple muscles in the back...

Where is skeletal muscle found? Skeletal muscles are muscles that are connected to and facilitate the movement of the skeleton. They are connected to the outer covering of bones, called the periosteum. This connection to the bone is through a type of connective tissue known astendons. ...

Striated muscle is connected directly to the central nervous system and is under the control of the will. In most cases it is attached to the skeleton. The muscle fibers are much larger than those of smooth muscle: an individual fiber may be from l to 40 mm long and l0 to l00 µm...
Ankle joint dorsiflexion and plantarflexion functionalities mainly account for ground clearance and propulsion power generation during locomotion tasks, where those functionalities are driven by the contraction of ankle joint skeleton muscles. Studies of corresponding muscle contractility during ankle dynamic ...
