How do the biceps quadriceps hamstrings deltoids gluteus maximus gastrocnemuis abdominals obliques pectorals trapezuis and erector spines work in order to produce movement?

Biceps

The biceps brachii is a two-headed muscle located on the front of the upper arm. It is responsible for flexing the elbow joint and supinating the forearm (turning the palm up).

Quadriceps

The quadriceps femoris is a four-headed muscle located on the front of the thigh. It is responsible for extending the knee joint.

Hamstrings

The hamstrings are a group of three muscles located on the back of the thigh. They are responsible for flexing the knee joint and extending the hip joint.

Deltoids

The deltoids are a group of three muscles located on the shoulder. They are responsible for abducting (moving away from the midline of the body), flexing, and extending the shoulder joint.

Gluteus maximus

The gluteus maximus is a large muscle located on the buttocks. It is responsible for extending the hip joint and stabilizing the pelvis.

Gastrocnemius

The gastrocnemius is a two-headed muscle located on the back of the lower leg. It is responsible for plantarflexing the ankle joint (pointing the foot down).

Abdominals

The abdominals are a group of muscles located on the front of the torso. They are responsible for flexing the spine and stabilizing the trunk.

Obliques

The obliques are a group of muscles located on the sides of the torso. They are responsible for rotating the spine and flexing the torso to the side.

Pectorals

The pectorals are a group of muscles located on the chest. They are responsible for flexing the shoulder joint and adducting (moving towards the midline of the body) the arm.

Trapezius

The trapezius is a large muscle located on the back of the neck and shoulders. It is responsible for elevating the shoulders, shrugging the shoulders, and rotating the head.

Erector spinae

The erector spinae is a group of muscles located on the back of the spine. They are responsible for extending the spine and stabilizing the trunk.

How these muscles work together to produce movement

The muscles of the body work together in a coordinated fashion to produce movement. For example, when you walk, your quadriceps muscles extend your knees to push your body forward. At the same time, your hamstrings flex your knees to allow your feet to swing forward. Your gluteus maximus muscles extend your hips to help you take each step. And your abdominal muscles contract to stabilize your torso.

The complex interplay of these and other muscles allows you to perform a wide variety of movements, from walking and running to jumping and dancing.
