No, the forearm extensors primarily arise from the lateral epicondyle of the humerus, not the medial epicondyle. The medial epicondyle is the origin for the forearm flexors. The extensors are responsible for extending the wrist and fingers, and their tendons run along the posterior side of the forearm.
No, it is the opposite. Muscles that bend a joint are called flexors, while muscles that straighten a joint are called extensors. For example, the biceps are flexors of the elbow joint, and the triceps are extensors of the elbow joint.
The adductor longus is a prime adductor and medial rotator of the femur. It is also an assistant mover for flexion at the hip. Therefore the antagonist muscles are the abductors (apposing adduction), the lateral rotators (apposing medial rotation) and the extensors (apposing flexion). Primary Abductors: Gluteus Medius and Gluteus Minimus Assistant Abductors: Tensor Fasciae Latter, Sartorius Primary Lateral Rotators: Glutteus Maximus, Deep Later Rotator group Assistant Lateral Rotators: Sartorius, Iliopsoas Primary Extensors: Hamstrings, Gluteus Maximus Assistant Extensors: Adductor Magnus (upper fibres)
The neck of the uterus is the cervix.
The head and neck extensors act as a third-class lever in the body. In this lever system, the fulcrum is located at the atlanto-occipital joint (where the skull meets the spine), the effort is applied by the extensor muscles at the back of the neck, and the load is the weight of the head. This arrangement allows for a greater range of motion and speed, though it requires more effort to lift the load compared to first-class levers.
shoulder depressors, extensors, adductors and abductors. elbow extensors, wrist extensors and finger flexors.
a muscle that extends or straighten a limb or body part is called extensor
Muscles that bend a joint are flexors; musces that straighten a joint are extensors.
Posterior
If both the flexors and extensors contracted simultaneously there would be no movement in the muscle whatsoever.
no. theyre extensors
