Abduction is an anatomical term of motion referring to a movement which draws a limb out to the side, away from the median sagittal plane of the body. It is thus opposed to adduction . Upper limb
The supraspinatus muscle performs abduction of the arm, and pulls the head of the humerus medially towards the glenoid cavity. [5] It independently prevents the head of the humerus from slipping inferiorly. [5] The supraspinatus works in cooperation with the deltoid muscle to perform abduction, including when the arm is in an adducted position. [5]
Avoiding movement of the shoulder joint allows the torn tendon to fully heal. [24] Once the tendon is entirely recovered, passive exercises can be implemented. Passive exercises of the shoulder are movements in which a physical therapist maintains the arm in a particular position, manipulating the rotator cuff without any effort by the patient ...
Plantarflexion of the foot: Primary muscles for plantar flexion are situated in the Posterior compartment of leg, namely the superficial Gastrocnemius, Soleus and Plantaris (only weak participation), and the deep muscles Flexor hallucis longus, Flexor digitorum longus and Tibialis posterior.
The nerve(s) which tell the muscle to act (innervates the muscle). The term "nerve" is included for clarity. Action The movement performed by the muscle from the standard anatomical position. In other positions, other actions may be performed. Antagonist The muscle which can 'cancel' or to some degree reverse the action of the muscle.
The axillary nerve is located at the proximal end, against the shoulder girdle. Dislocation of the humerus's glenohumeral joint has the potential to injure the axillary nerve or the axillary artery. Signs and symptoms of this dislocation include a loss of the normal shoulder contour and a palpable depression under the acromion.
Superior rectus muscle; Inferior rectus muscle; Medial rectus muscle; jaw (muscles of mastication, the closing of the jaw is adduction): masseter; pterygoid muscles (lateral and medial) temporalis; vocal folds. Lateral cricoarytenoid muscle
