Which muscle group is primarily responsible for stabilizing the scapula during upper limb movements?

A. Muscle atrophy:Muscle atrophy is loss of muscle mass seen in disuse or neuromuscular disease rather than a hallmark of fibromyalgia.
B. Localized joint inflammation:Localized joint inflammation suggests inflammatory arthritis, which differs from fibromyalgia’s noninflammatory pain.
C. Widespread musculoskeletal pain:Widespread musculoskeletal pain, often accompanied by fatigue and sleep disturbance, is a defining feature of fibromyalgia.
D. Skin rashes:Skin rashes are not a typical symptom of fibromyalgia and point toward dermatologic or systemic inflammatory conditions.

A. To allow spinal cord passage:The foramen magnum is the large opening at the skull base through which the brainstem continues as the spinal cord and major vessels and nerves pass.
B. To house the pituitary gland:The pituitary gland sits in the sella turcica of the sphenoid bone, not in the foramen magnum.
C. To anchor meninges:While meninges attach to cranial structures, anchoring of meninges is not the primary role of the foramen magnum.
D. To attach facial muscles:Facial muscles attach to facial bones and soft tissue rather than to the foramen magnum.
