The soleus plays an important role in maintaining standing posture; if not for its constant pull, the body would fall forward. Also, in upright posture, the soleus is responsible for pumping venous blood back into the heart from the periphery, and is often called the skeletal muscle pump, peripheral heart or the sural (tricipital) pump. [5]
When moving upright, the blood volume moves to the peripheral parts of the body. To combat this, the muscles involved in standing contract and help to bring venous blood volume to the heart. [1] [2] The pump is important in affecting the central and local supply of blood output. [3]
Inferior end of lateral supracondylar line of femur; oblique popliteal ligament: Weakly assists gastrocnemius in plantarflexing ankle Soleus: Posterior aspect of head and superior quarter of posterior surface of fibula; soleal line and middle third of medial border of tibia; and tendinous arch extending between the bony attachments
Skeletal muscle cell types include: very large multinuclear muscle fiber cells; small endothelial cells that line the inside of capillary blood vessels; small fibro-adipogenic progenitor cells (FAPs) which are muscle-fiber-adjacent multipotent mesenchymal stem cells that under different conditions can differentiate into adipocytes, fibroblasts ...
The triceps surae consists of two muscles located at the calf – the two-headed gastrocnemius and the soleus.These muscles both insert into the calcaneus, the bone of the heel of the human foot, and form the major part of the muscle of the posterior leg, commonly known as the calf muscle.

Reviewed by Dietitian Annie Nguyen, M.A., RD. Your heart is arguably the hardest-working muscle in your body. Every day it pumps nearly 2,000 gallons of blood through your arteries to supply the ...
The soleal line marks the lower limit of the insertion of the popliteus muscle. [2] It is the attachment of the fascia covering this muscle. It is the origin of part of soleus muscle (along with a triangular area above it), [ 3 ] flexor digitorum longus muscle , and tibialis posterior muscle .
