Yes they are. The Bicep muscle is attached to the humerus bone (upper arm) at the front. It's the muscle that contracts when you want to bend your arm at the elbow. The tricep muscle is attached to the same bone - but runs down the back. It straightens your arm when it contracts.

What is the properties of the biceps muscle?
Most muscles in the body have "counterparts", one pulls and your leg curls up, the other pulls and the leg straightens. They would be on opposite sides of your leg. The "biceps" are the upper arm top muscle, and the tri-ceps (I think) is the upper arm bottom muscle. They work in conjunction to let you 'curl a barbell'' or do a chin-up.
What is the muscle that causes parts of the body to bend?
A flexor is a muscle that causes a joint to bend. In contrast, an extension is a muscle that straightens a joint.
Why does your muscle form a hump when your arm is bent?
A muscle can do one of two things: it can contract, or it can relax. If the muscle is connected by tendons to bones, it will then pull on those bones when it contracts, and it will stop pulling on them when it relaxes. The arrangement of bones and muscles in the human arm allows muscles to bend the arm, by contracting. Also, muscles work in pairs. One muscle bends the arm while another straightens it out again. A single muscle can only pull in one direction, so you need a combination of muscles to be able to move around in a useful manner.
What does extension do in relation to muscle movements?
To extend a muscle A MOTION IS MADE TO INCREASE AN ANGLE BETWEEN TWO BONES.
What is the purpose of your triceps?
The primary function of the biceps muscles is elbow flexion or mowing your arm towards the shoulder. It's secondary function is hand/arm supination, which is the movement of your hand from facing downward to facing upwards. On the other hand, the triceps' primary function is to straighten the arm or extending the elbow. The triceps' muscles also helps in the movement of the arm towards the body or moving your arm from out to inside or towards the mid line of your body which is called adduction. this secondary function is performed together with the muscle Latissimus Dorsi.
