Final answer:
The sternal end of the clavicle articulates with the manubrium. The sternum, composed of the manubrium, body, and xiphoid process, does not have a commonly referred-to 'Sterno-Metric Reference' point specifically for measuring shoulder pads, making the correct answer 'None of the above'.
Step-by-step explanation:
The sternum is an important bone in the thoracic region, serving as a key anatomical landmark. It is comprised of the manubrium, body, and xiphoid process. The manubrium is the upper part of the sternum, which is notable for its jugular notch and clavicular notches, where it articulates with the clavicle at its sternal end.
Regarding the schoolwork questions provided, the part of the clavicle that articulates with the manubrium is the sternal end.
The sternum also features the sternal angle, the point where the manubrium meets the body and forms a slight bend. The xiphoid process is the smaller, lower portion of the sternum, and while it may be a palpable landmark, it is not the preferred reference for measuring shoulder pads.
The tip of the sternum generally refers to the xiphoid process, but in the context of measuring shoulder pads, the term 'Sterno-Metric Reference' is not commonly used in medical or sports fitting terminology. The most appropriate option based on the provided information is d) None of the above.
