biceps brachii,corahobrachialis,biseps
Elbow flexion primarily involves the hinge joint formed by the humerus (upper arm bone) and the ulna (one of the two bones in the forearm). The radius, the other forearm bone, also plays a role but to a lesser extent. The main muscles responsible for elbow flexion are the biceps brachii and brachialis.
Flexion is movement during which the knees or elbows are bent to decrease the angle of the joint
flexion and extension
at the elbow. "Flexion of the arm" just means to bend it.
Flexion and extension
The bones involved in long jump are the femur, fibula, tibia, vertebra, metatarsals, phalanges, ulna, radius, and the humerus. The muscles used in the same activity are the gastrocnemius, glutes, quadriceps, hamstrings, biceps, deltoids, triceps, trapezius, latissimus, dorsi, quadriceps, and the abdominals. It also includes the elbow, shoulder, and hip ball and socket joint, the elbow, patella, and toes hinge joint, and the ankles condyloid and synovial joint. The joint actions are flexion, extension, and abduction.
The elbow joint has a humeroulnar and humeroradial joint. The humeroulnar joint allows flexion and extension movements, while the humeroradial joint allows for pronation and supination movements.
When lifting a cup to your mouth, the joint movement primarily involves flexion at the elbow joint. Additionally, there may be some involvement of shoulder joint abduction and wrist joint extension to bring the cup to your mouth.
They are hinge joints. The elbow has only one plane of motion (flexion & extension); however, the knee is considered a "modified hinge" because it has the flexion & extension as well as a rotational (pivot) component as well.
Elbow joint consists of three joints:Joint between trochlea of Humerus and Ulna is hinge joint (ginglymus joint).Joint between capitulum of humerus and head of radius is also a hinge joint.Joint between Upper ends of radius and ulna is pivot joint.
The main joint involved in flexion of the knee is the hinge joint formed by the femur and tibia. Additionally, the patellofemoral joint between the patella and femur also plays a role in knee flexion by aiding in the smooth movement of the patella during flexion.
Flexion (same as bending) at the elbow joint (between the humerus and the radius and ulna) is mainly achieved by the Brachialis Muscle. This is not the answer most would expect as everyone knows the Biceps Brachii (Biceps of the arm) are what flexes this joint. In fact the biceps does both supination and flexion of the elbow because its insertion is on the radius. Only when the forearm is supinated, the biceps is able to assist the deeper and more powerful brachialis muscle with the flexion of the elbow.
