American Heritage® Dictionary of the English Language, Fourth Edition
- n. The largest, most prominent muscle of the calf of the leg, the action of which extends the foot and bends the knee.
Century Dictionary and Cyclopedia
- n. A superficial muscle of the posterior tibial region, arising from the femur and inserted into the tarsus, the action of which extends the foot upon the leg, and flexes the leg upon the thigh: so called from its character in man, in whom it forms, together with the soleus, the protuberant or “bellying” part of the calf of the leg. In man the gastrocnemius arises by two heads, inner and outer, from the corresponding condyles of the femur, is joined by the soleus, and then forms a very stout tendon, the tendo Achillis, which is inserted into the tuberosity of the os calcis or heel-bone. (See cut under
muscle .) In animals in which there is no soleus the two heads of the gastrocnemius often form two muscles, distinct in their whole length, with separate Achillean tendons.

reesetee You sly dog, you.
I mean bear. Mar 5, 2008
chained_bear Yes, he was watching an orang-utang. I purposely left that part out. Makes it a rather interesting excerpt. :) Mar 5, 2008
reesetee I presume he was referring to a non-human animal, c_b? Because I didn't think that until I got to the last phrase.... Mar 5, 2008
chained_bear "He took the most particular notice of her progression, her muscular movements, the paucity of the gluteus maximus, the odd disposition and contraction of the gastrocnemius, and on the other hand the prodigious breadth of shoulder and very powerful great arms—clearly an animal made for moving among trees."
--Patrick O'Brian, The Thirteen Gun Salute, 221–222 Mar 5, 2008
