The biceps flexes the arm it does not extend it (straightens). The triceps brachii extends the arm. They do work together. If one is damaged and doesn't work as it should, the movement will be "jerky" and not smooth.
The biceps contract to pull up the arm, and then to relax, while the triceps lower the arm. Muscles work in pairs to move the articulate skeleton parts.
The movement would be 'jerky' and not at all smooth.
They are the opposite muscle to the biceps. If you bend your arm to make the muscle on the top (the biceps) bulge, the muscle on the bottom (the triceps) relaxes. The triceps is on the back of your arm, and is used to straighten the elbow.
Women have biceps (brachii) in the arms just as men do. They don't work them to make them as large. Some do but most don't work out that way. Their muscles seem leaner and flatter.
my biceps r steel, bro.
Your triceps are ment to be bigger....after all they are two thrids of the upper arm....people seem to focus on increasing the size of their biceps, this doesn't make there arms look much bigger and also can cause great damage. If I were you I would work out your triceps just as much as biceps, if not more ;)
The make you sing "How I Like My Biceps" while jacking off
You cannot and should not even attempt to straighten a dogs tail if it is curled. Some dogs are born with little differences, these things only make them special~!
Many people have the misconception that biceps play an important role in Weightlifting. The biceps muscle is relatively unimportant in good weightlifting technique. The force for lifting and accelerating the bar is produced in the legs and the quadriceps is the main muscle group. The triceps play an important part in holding weights overhead. The function of the tricep is to straighten the arm, and in holding a weight overhead the elbows must be locked out and the triceps make this happen.
If you're a guy straighten it, if you're a girl straighten it.

You cannot do so with geometry alone
Straighten it
You can always straighten curly hair if it is naturally curly. If it is permed to be curly, then ask your hairdresser what to do if you want to make it straight.
