Structure[edit] The two muscle layers that make up the triceps surae, namely the gastrocnemius and soleus. The triceps surae is connected to the foot through the Achilles tendon, and has 3 heads deriving from the 2 major masses of muscle. The superficial portion (the gastrocnemius) gives off 2 heads attaching to the base of the femur directly above the knee.
Generally, these muscles are attached to bones of the skeleton, thus called the skeletal muscles. Skeletal muscles are striated and are made up of multinucleate cells. Each cell is referred to as muscle fiber.The cell membrane of muscle fiber is known as sarcolemma, and the cytoplasm is called sarcoplasm. Unlike involuntary muscles, voluntary muscles are attached to bones. Involuntary muscles are visceral. â¢ Voluntary muscle tissue is made up of cylindrical fibres, while involuntary muscles (smooth muscles) are made up of spindle-shaped fibres.
