Clavicle
Scapula
Ulna
Scaphoid
Pollex
The Correct Answer is B

Choice B reason: The scapula is the correct answer. The acromion is a bony process on the scapula that extends laterally over the shoulder joint and articulates with the clavicle to form the acromioclavicular joint.
Choice C reason: The ulna is a forearm bone and does not have an acromion. It forms part of the elbow joint.
Choice D reason: The scaphoid is a carpal bone in the wrist and is unrelated to the shoulder girdle or the acromion.
Choice E reason: The pollex refers to the thumb and is not associated with the acromion or shoulder anatomy.

Choice A reason: Protection of the brain is the primary function of cranial bones. They form the skull, which encases and shields the brain from mechanical injury.
Choice B reason: Muscles attach to facial bones, not cranial bones. While cranial bones may serve as attachment sites for some muscles, this is not their main function.
Choice C reason: The introduction of food into the digestive system involves the mouth and associated facial structures, not cranial bones.
Choice D reason: Passageways for respiratory gases are formed by facial bones and nasal structures, not the cranial bones.
Choice E reason: Special sense organs such as the eyes, ears, and nose are housed in facial bones and cavities, not primarily in cranial bones. Cranial bones protect the brain, not sensory organs.
