Identify as many pairs of antagonistic muscle groups in the body as you can. If you cannot name them, point out the probable location of the flexor and extensor of each group.

Expert Solution

Summary Introduction

To determine: The pairs of antagonistic muscle groups present in the human body.

Introduction: Muscles are the bundle of fibrous tissue present in the body of an organism. The muscles are responsible for the contraction, movements and maintaining the position of different body parts.

Explanation of Solution

Antagonistic muscles are the group of muscles that move bones in the opposite direction. This is because the muscle contraction can pull the bone, but it can not push the bone away. The antagonistic group of muscles consists of flexor and extensor pair of muscle.

Some of the antagonistic muscle groups are as follows:

Biceps and triceps muscle.
Hamstring and quadriceps muscles.
Tibialis anterior and gastrocnemius muscles.

Conclusion

Thus, biceps and triceps muscle; hamstring and quadriceps muscles; and tibialis anterior and gastrocnemius muscles are some of the antagonistic muscles present in a body.

Expert Solution

Summary Introduction

To determine: The location of flexor and extensor muscles in antagonistic muscle groups.

Introduction: Flexor muscles bring the bones close together after contraction. This movement of contraction of flexor muscles is called flexion. On the other hand, extensor muscles move away the bone from each other after contraction. The movement of contraction of extensor muscles is called extension.

Explanation of Solution

Some of the antagonistic muscle groups with their location are as follows:

Biceps and triceps muscle present in the upper arm. Biceps are flexor muscles, whereas triceps are extensor muscles.
Hamstring and quadriceps muscles present in the upper leg in which hamstring are flexor muscles and quadriceps are extensor muscles.
Tibialis anterior and gastrocnemius muscles are present in the ankle for the foot movement. Tibialis anterior is the flexor muscle, whereas gastrocnemius is the extensor muscles.

Conclusion

Thus, biceps, hamstring and tibialis anterior are the flexor muscles whereas triceps, quadriceps and gastrocnemius are the extensor muscles.
