What is a flexion of the arm?
Arm flexion represents rotation in the anatomic plane such that the distal humerus moves ventrally. It represents raising the arm and isolated flexion can achieve approximately 150-170° of movement. The opposite movement is arm extension and contributes to the combined movement of shoulder circumduction.
Which is an example of flexion at a joint?
Flexion – bending a joint. This occurs when the angle of a joint decreases. For example, the elbow flexes when performing a biceps curl. The knee flexes in preparation for kicking a ball.
What is an example of flexion body movement?
In the limbs, flexion decreases the angle between the bones (bending of the joint), while extension increases the angle and straightens the joint. In the lower limb, bringing the thigh forward and upward is flexion at the hip joint, while any posterior-going motion of the thigh is extension.
What muscles are used in flexion of the arm?
Flexion (forearm towards upper arm): Produced by the brachialis, biceps brachii, and brachioradialis of the forearm. Pronation (rotation of the forearm so the palm faces downwards): Produced by the pronator quadratus and pronator teres of the forearm.
What are the two types of movements?
Types of joint movement in the skeletal system
- Flexion – bending a joint.
- Extension – straightening a joint.
- Abduction – movement away from the midline of the body.
- Adduction – movement towards the midline of the body.
- Circumduction – this is where the limb moves in a circle.
What is Flexation give two examples?
This is the classic example of flexion. Flexion is a movement in which the angle between two body segments gets smaller. Take a minute to think of any two body segments next to each other. Examples are the hand and forearm, thigh and shin, arm and torso, etc.
What is the difference between arm flexion and arm extension?
Shoulder flexion, also called arm flexion, occurs when the angle at the humerus of the arm and the scapula decreases as the arms move anteriorly. In contrast, shoulder extension (or arm extension) occurs when the angle at the humerus of the arm and the scapula increases, causing the arm to move posteriorly.

Which is an example of an arm exercise?
Example Exercises: Dumbbell/barbell biceps curls, hammer curls, preacher curls Location: The triceps brachii (or triceps for short) are located on the posterior (back) part of your upper arm between your elbow and shoulder.
Which is an example of shoulder flexion in sports?
Lifting a child, hailing a cab, and reaching for a can on the top shelf of your pantry — these are all examples of shoulder flexion. This movement is also integral to most sports that utilize the upper body; every time a volleyball player bump passes or a power forward shoots a three-pointer, they’re using shoulder flexion.
