Flexion of the arm at the shoulder occurs primarily in the sagittal plane. This movement involves raising the arm forward and upward, decreasing the angle between the arm and the front of the body. It typically involves the use of muscles such as the deltoid and biceps brachii.
Shoulder circumduction is a multiplanar motion that occurs in the sagittal, frontal, and transverse planes. It involves a combination of flexion, extension, abduction, adduction, and internal and external rotation at the shoulder joint.
Plantar flexion occurs in your feet.
During a sit-up, the primary joint movements that occur are hip flexion as the hips bend, lumbar spine flexion as the back rounds forward, and thoracic spine flexion as the upper body moves towards the knees. The shoulder movement might also involve slight flexion as the arms reach forward towards the knees.
When the pectoralis major contracts eccentrically, it undergoes controlled lengthening. This action can assist in shoulder extension, as well as contribute to shoulder adduction from an abducted position.
Though flexion and extension can occur in a variety of planes depending on the body's position, if you have a body in anatomical position, then all flexion and extension occurs on the sagittal plane.
sagitall (side view) just think if you had a video camera on the side of someone you would see movement take place from this view
at the elbow. "Flexion of the arm" just means to bend it.
Frontal Plane about the anterioposterior axis
During the upward movement of a shoulder press, several joint actions occur primarily at the shoulder and elbow. The shoulder joint undergoes shoulder flexion as the arms move upward, while the scapulae also upwardly rotate to facilitate this motion. At the same time, the elbow joint extends as the forearms push upward, effectively straightening the arms. These coordinated movements engage multiple muscle groups, including the deltoids, triceps, and upper back muscles.
The shoulder joint is capable of circumduction, which is a multiplanar movement that involves the combination of flexion, extension, abduction, and adduction. This complex movement allows the arm to move in a circular pattern, such as when throwing a ball in baseball or reaching for an object overhead. The shoulder joint's unique structure, with its shallow socket and wide range of motion, enables circumduction to occur efficiently.
Firstly they put there arm back over there head using the ball and socket joint at your shoulder to get the power you then use flexion and extension to throw the ball forwards towards the team mate.
