The facial muscles are just under the skin (subcutaneous) muscles that control facial expression. They generally originate from the surface of the skull bone (rarely the fascia), and insert on the skin of the face. When they contract, the skin moves. These muscles also cause wrinkles at right angles to the muscles’ action line. [2]
In rock climbing a face climb is a type of climbing route where the rock face is fully vertical, unlike in slab climbing, and is largely featureless, unlike in crack climbing. Face-climbing routes are typically sustained and exposed, and longer multi-pitch face-routes can become big wall climbing .
On either side, the epicranial aponeurosis attaches to the anterior auricular muscles and the superior auricular muscles. Here it is less aponeurotic , and is continued over the temporal fascia to the zygomatic arch as a layer of laminated areolar tissue .

Muscles are often paired as agonistic and antagonistic muscles. [20] This can be a bit misleading as, in general, it is groups of muscles working together to either make or cancel a movement. [21] The present table lists some well-known relationships but is not at all complete.
In rock climbing, an overhang is a type of route that leans back at an angle of over 90 degrees for part or all of the climb, and at its most severe can be a horizontal roof. Overhang (and roof) climbs have existed throughout climbing, originally in aid climbing where mechanical devices were used to first scale them.
The muscle-up begins with the arms extended above the head, gripping a hold in the overhand pull-up position. The hold is usually on a chin-up bar or gymnastic rings.. The body is then explosively pulled up by the arms in a radial pull-up, with greater speed than a regular pull-up.
The occipitalis muscle (occipital belly) is a muscle which covers parts of the skull.Some sources consider the occipital muscle to be a distinct muscle. However, Terminologia Anatomica currently classifies it as part of the occipitofrontalis muscle along with the frontalis muscle.
