medial head

me·di·al head

[TA]
the head of origin closest to the midline. Terminologia Anatomica lists medial head (caput mediale) of the following: 1) triceps brachii [TA] (... musculi tricipitis brachii [TA]); 2) gastrocnemius [TA] (... musculi gastrocnemii [TA]); and 3) flexor hallucis brevis [TA] (... musculi flexoris hallucis brevis [TA]).
Synonym(s): caput mediale [TA]

Conversely, AFDL is speculated to represent an evolutionary remnant of the portion of the flexor hallucis longus muscle that migrated from the leg to the plantar foot to become the medial head of the quadratus plantae muscle [16, 35, 36].
A palpable mass behind the knee joint, which typically expands the subcutaneous tissue, occurs between the semimembranosus and medial head of the gastrocnemius tendons [4, 5].
Both the medial head and lateral head can be used, but the former is more commonly utilised because of its larger size and the absence of the fibula which can represent an obstacle with regard to stretching and reaching the distant point for coverage.
Next, care is taken to expose the interval between the semimembranosus and medial head of the gastrocnemius, both of which are supplied by branches of the tibial nerve.
Normally, the myotendinous junction of plantaris occurs approximately at the level of origin of soleus muscle from tibia in the proximal part of leg, the long tendon passes between the medial head of gastrocnemius and soleus, continues along the medial aspect of tendocalcaneus for its insertion on calcaneum either independently or in association with tendocalcaneum, Andreo A Spina DC.
The probable cause of such hypermobility is congenital laxity of supporting ligaments (epicondyloolecranial ligament) [3,4], dysplasia of the retrocondylar ulnar groove [10], pushing out the ulnar nerve from its sulcus by the prominent medial head of triceps muscle when flexing the elbow [10,11-13], muscular anomalies and muscular variations around the medial elbow [14,15].
Baker's cysts are situated between the medial head of the gastrocnemius muscle and the insertion of the semimembranous muscle.
