Powerful thigh extensor when climbing stairs it can laterally rotate and abduct the thigh

It is true that powerful thigh extensor when climbing stairs it can laterally rotate and abduct the thigh, due to the combined action of the muscles that form it.

Explanation:

Thigh extensors are a group of muscles located in the front of the thigh, needed for walking, running, jumping, climbing stairs, or bending.

Thigh extensors form a combined structure, called the quadriceps femoris:

In addition, the longest muscle of the muscular system, the sartorius, is found within the thigh extensors.

When climbing stairs, one of the functions of the thigh extensors is to produce the external rotation and abduction - midline separation - of the thigh, a function specifically performed by the vastus laterale muscle.

relative dating involves things like higher layers are most recent than rocks lower in the sequence. this can be extended to the known sequence of fossils. rocks containing rabbit fossils are later than those containing dinosaur fossils.  

absolute dating methods mainly use radioactive elements that have known rates of decay and produce recognizable products. for example potassium 40 decays to produce argon. once a rock has solidified the argon is trapped. by measuring the argon and potassium0 you can get an accurate number for the age.  

some other methods are good for archaeological ages. dendrochronology involves recognizing the sequence of tree rings. the orientation of magnetized particles in baked clay can be used to date a fire.
