Movement of the shoulder laterally away from the body is called:
A
Adduction
B
Abduction
C
Flexion
D
Extension
Verified step by step guidance1
Step 1: Understand the anatomical terms related to movement. 'Adduction' refers to movement toward the midline of the body, while 'Abduction' refers to movement away from the midline. 'Flexion' and 'Extension' are movements that typically occur in the sagittal plane, involving bending and straightening of a joint, respectively.
Step 2: Focus on the shoulder joint. The shoulder is a ball-and-socket joint that allows a wide range of movements, including abduction, adduction, flexion, extension, and rotation.
Step 3: Visualize the movement described in the problem. 'Laterally away from the body' indicates movement away from the midline, which aligns with the definition of abduction.
Step 4: Compare the options provided. 'Adduction' is the opposite of abduction, as it involves movement toward the midline. 'Flexion' and 'Extension' do not describe lateral movement but rather forward and backward motion.
Step 5: Conclude that the correct term for the movement described is 'Abduction,' as it matches the definition of moving the shoulder laterally away from the body.
