Difference Between Biceps and Triceps

Main Difference

The main difference between Biceps and Triceps is that Biceps is the muscle which is made up of two muscle bundles that are the short head and the long head whereas Triceps is the muscle which is made up of three muscle bundles including the long head, the lateral head, and the medial head.

Biceps vs. Triceps

Muscle is defined as a soft tissue which is found in most of the animals. Its cells consist of protein filaments of myosin and actin that slide over one another, which produces a contraction and changes both the shape and length of the cells. The function of muscles is to produce motion and force. The biceps and triceps are two muscles of our upper arm. These enable us to do a lot of activities like move things, climb and lift heavy objects. We also use the term “biceps brachii” for biceps. This term was originated from the Latin word ‘musculus,’ which means the “little mouse.” It is because the appearance of the flexed biceps resembles the back of a mouse. Conversely, the term “triceps brachii” is also used for triceps. The term “triceps” is also originated from the two Latin words, tri means “three,” and ceps means “head.” Actually, biceps are referred to as a “two-headed muscle.” Triceps, on the other hand, started as a “three-headed muscle.” Biceps are the muscles which are made up of two muscle bundles, viz. the short head and the long head. Triceps, on the flip side, are the muscles which are made up of three muscle bundles viz. the long head, the medial head, and the lateral head.

Also Known As
Biceps are also known as the “biceps brachii.”Triceps are also known as the “triceps brachii.”
Origin
The term “biceps” was originated from the Latin word ‘musculus,’ which means the “little mouse.”The term “triceps” is also originated from the two Latin words, tri means “three,” and ceps means “head.”
Reason of Origin From Latin
The flexed biceps look like the back of a mouse. So, it was the reason for its origin from the Latin word ‘musculus.’Triceps are stated as a “three-headed muscle.” That’s why they have originated from the two Latin words tri, means “three,” and ceps means “head.”
Muscle Bundles
Biceps contain muscle bundles viz. the short head and the long head.Triceps contain muscle bundles viz. the long head, the lateral head, and the medial head.
Location
Biceps are present at the front of the upper arm.Triceps are present at the back of the upper arm.
Function
Biceps work as flexors.Triceps work as extensors.
Responsible For
Biceps are responsible for moving the shoulder, elbow and for forearm rotation.Triceps are responsible for extending the elbow, moving the shoulder and the elbow but in the opposite direction to the biceps.
Action
Biceps show the pulling action.Triceps shows the pushing action.
Angle
They decrease the angle between the upper arm and the forearm.They increase the angle between the upper arm and the forearm.
Development
To develop biceps, we should do the types of exercises that bring the weight closer to our body.To develop the triceps, we should do the types of exercises that include pushing the weight away from our body.

What is Biceps?

Biceps are made up of two types of muscle bundles viz. the short head and the long head. They are also known as the “biceps brachii.” They show the pulling action and decrease the angle between the upper arm and the forearm. They work as flexors and are responsible for moving the shoulder, elbow and for forearm rotation.

What is Triceps?

Triceps are made up of three types of muscle bundles viz. the long head, the lateral head, and the medial head. They are also known as “triceps brachii.” They show the pushing action and increase the angle between the upper arm and the forearm. They work as extensors.

Key Differences

  1. Biceps is the muscle which is made up of two muscle bundles, whereas, triceps is the muscle which is made up of three muscle bundles.
  2. Biceps are also called as the “biceps brachii,” on the other hand, triceps are also known as the “triceps brachii.”
  3. The term “biceps” was originated from the Latin word ‘musculus,’ which means the “little mouse.” Conversely, the term “triceps” is also originated from the two Latin words tri, means “three,” and ceps means “head.”
  4. The appearance of the flexed biceps looks like the back of a mouse. So, it was the reason for its origin from the Latin word ‘musculus,’ on the other hand, triceps are stated as a “three-headed muscle.” That’s why they have originated from the two Latin words tri, means “three,” and ceps means “head.”
  5. Biceps contain muscle bundles muscle viz. the short head and the long head, on the flip side, triceps contain muscle bundles muscle viz. the long head, the lateral head, and the medial head.
  6. Biceps are present at the front of the upper arm; on the other side, triceps are present at the back of the upper arm.
  7. Biceps are the particular muscles which function as flexors, while, triceps are the particular muscles which function as extensors.
  8. Biceps are responsible for moving the shoulder and elbow and for forearm rotation, on the other hand, triceps are responsible for extending the elbow and moving the shoulder and the elbow but in the opposite direction to the biceps.
  9. The pulling action is shown by the Biceps, whereas, the pushing action is shown by the triceps.
  10. Biceps are the muscles which decrease the angle between the upper arm and the forearm, on the flip side, triceps are the muscles which increase the angle between the upper arm and the forearm.
  11. To develop the biceps, we should do the types of exercises that bring the weight closer to our body, on the other hand, to develop the triceps, we should do the types of exercises that include pushing the weight away from our body.

Conclusion

The above discussion summarizes that biceps and triceps are responsible for our arms movement. They help us to keep up our daily activities.
