Triceps and Biceps
shoulder depressors, extensors, adductors and abductors. elbow extensors, wrist extensors and finger flexors.
The two major groups are flexors and extensors.
The forearm muscles are a group of muscles located in the forearm that are responsible for movements of the wrist and fingers. These muscles are important for activities such as gripping, lifting, and twisting. Some of the major forearm muscles include the flexor and extensor muscles.
There are about 20 muscles in a forearm, consisting of flexors and extensors. Flexors are responsible for flexing the forearm, wrist, and fingers.
The thumb extensors are examples of muscles that attach to the ulna bone. The ulna bone is one of the two long bones in the forearm and can also be called the elbow bone.
Muscles that bend a joint are flexors; musces that straighten a joint are extensors.
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)
There are flexors and extensors in the forearm and they control the movements of the hand and wrist. If you hold your hand out (with the palm down), the flexors allow your hand to bend downward. The extensors allow your hand to bend upward.
Biceps Brachii is a powerful supinator of the forearm, the Supinator muscle also completes supination of the forearm particularly when the forearm is supinating in a slow and unopposed manor or if the forearm is extended.
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 Radial Nerve.
Skeletal muscles work in pairs: flexors and extensors
