Form “—Elongated ; and flattened from without inward. 
Attachment .—Superiorly, to the postero-inferior part of the 
external condyle: inferiorly (by one division of its tendon) to the

tacarpal bone.

cessorius sublimis, and next muscle; antero-externally, with the

one : the latter as continued down at the back of the knee, in 
contact with the capsular ligament, enveloped within a tendinous 
sheath.
