ICan2Ed, Inc.
The clavicle is a long curved, horizontal bone directly
above the first rib, forming the ventral portion of the
shoulder girdle. The slender S-shaped bone that
extends horizontally across the superior thorax is the
c_____.
The c_____ extends from the manubrium of the
sternum to the acromion of the scapula.
The pectoral girdle is constructed of 2 c_____ bones
and 2 scapulae.
The doubly curved long bones that form the anterior
part of the pectoral (shoulder) girdle are the c_____
bones.
The c_____ is a long curved, horizontal bone directly
above the first rib, forming the ventral portion of the
pectoral (shoulder) girdle.
The c_____ is a long S-shaped bone that connects the
torso with the upper arm.
1
The c_____ is a slender bone, wider medially at the
sternoclavicular joint.
The c_____ is convex at the medial end, and concave at
the lateral end.
The female c_____ is shorter, lighter, thinner,
smoother, and less curved than in males.
The c_____ is a long curved, horizontal bone directly
above the first rib, forming the ventral portion of the
pectoral (shoulder) girdle.
The c_____ is a long S-shaped bone that connects the
torso with the upper arm.
The end that attaches to the sternum is called the
medial (toward the midline) end. The m_____ end is
called the sternal end.
2
The s_____ e____ articulates with the clavicular notch
of the manubrium sterni to form the sternoclavicular
joint.
The s_____ e____ of the clavicle is held in the
sternoclavicular joint by the sternoclavicular ligament.
The c_____ is a long curved, horizontal bone directly
above the first rib, forming the ventral portion of the
pectoral (shoulder) girdle.
The c_____ is a long S-shaped bone that connects the
torso with the upper arm.
The s_____ e____ of the clavicle articulates with the
clavicular notch of the manubrium sterni to form the
sternoclavicular joint.
The m_____ end also articulates with first costal
cartilage because of the extension of the articular
surface.
3
The first costal cartilage joins the first rib with a notch
on the side of the m_____, inferior to the
sternoclavicular joint.
The first costal cartilage joins the first rib with a notch
on the side of the m_____ called the costal notch 1.
The c_____ is a long curved, horizontal bone directly
above the first rib, forming the ventral portion of the
pectoral (shoulder) girdle.
The c_____ is a long S-shaped bone that connects the
torso with the upper arm.
The s_____ e____ of the clavicle articulates with the
clavicular notch of the manubrium sterni to form the
sternoclavicular joint.
The first costal cartilage joins the first rib with a notch
on the side of the m_____ called the costal notch 1,
inferior to the sternoclavicular joint.
4
The end that articulates with the acromion process is
called the lateral (toward the outside) end. The l_____
end is called the acromial end.
The a_____ e____ articulates with the acromion
process of the scapula at the acromioclavicular joint.
The a_____ e____ articulates with the acromion of the
scapula by the acromio-clavicular ligament and to the
coracoid process of the scapula by the coraco-clavicular
ligament.
The articular surface for the a______ e____ gives
attachment to the joint capsule of the humerus.
The c_____ is a long curved, horizontal bone directly
above the first rib, forming the ventral portion of the
pectoral (shoulder) girdle.
The c_____ is a long S-shaped bone that connects the
torso with the upper arm.
5
The s_____ e____ of the clavicle articulates with the
clavicular notch of the manubrium sterni to form the
sternoclavicular joint.
The first costal cartilage joins the first rib with a notch
on the side of the m_____ called the costal notch 1,
inferior to the sternoclavicular joint.
The a_____ e____ articulates with the acromion
process of the scapula at the acromioclavicular joint.
The articular surface for the a______ e____ gives
attachment to the joint capsule of the humerus.
