The calf (pl.: calves; Latin: sura) is the back portion of the lower leg in human anatomy. [1] The muscles within the calf correspond to the posterior compartment of the leg . The two largest muscles within this compartment are known together as the calf muscle and attach to the heel via the Achilles tendon .
Both men and women generally consider long legs attractive, [69] which may explain the preference for tall fashion models. Men also tend to favor women who have a higher leg length to body ratio, but the opposite is true of women's preferences in men.

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.
Soleus muscles have more slow muscle fibers than many other muscles. In some animals, such as the guinea pig and cat, soleus consists of 100% slow muscle fibers. [6] [7] Human soleus fiber composition is variable, containing between 60% and 100% slow fibers. [8] The soleus is the most effective muscle for plantar flexion in a bent knee position.
The muscle which can 'cancel' or to some degree reverse the action of the muscle. Muscle synergies are noted in parentheses when relevant. O (Occurrences) Number of times that the named muscle row occurs in a standard human body. Here it may also be denoted when a given muscles only occurs in a male or a female body.
The gastrocnemius muscle is prone to spasms, which are painful, involuntary contractions of the muscle that may last several minutes. [5] A severe ankle dorsiflexion force may result in a Medial Gastrocnemius Strain (MGS) injury of the muscle, commonly referred to as a "torn" or "strained" calf muscle, which is acutely painful and disabling.
