The distal (acromial) end of the clavicle looks like a field hockey
stick. Remember that the end of the hockey stick that touches the ground
is distal to your hands. The inferior side is recognized by the fact the
distal end has a concavity that faces downward while the superior side is smooth. It articulates with the
acromion process of the scapula. The distal end of
the clavicle is of functional importance because it is the origin for:
1. the anterior division of the deltoid muscle,

It is also the insertion for:
1. the superior division of the trapezius muscle.

The above drawings of the origin and
insertion might help visualize this information (red is the origin, blue the
insertion). Improved photos were donated by Paula S.
(fall 2007). Thank you so much Paula!
