Bones of the upper limb Flashcards
Bone that connects the upperlimb to the trunk
Clavicle (collar bone)
Part of the clavicle articulating with the manubrium
Sternal end
Articulation of the sternal end of the clavicle and the manubrium
Sternoclavicular joint
Part of the clavicle articulating with the acromion process
Acromial end
With which bone does the sternal end of the clavicle articulate?
Manubrium of the sternum
Articulation of the manubrial end of the clavicle and the acromion
Acromioclavicular joint
The medial two thirds of the clavicle are concave anteriorly. T/F
F
It is convex anteriorly.
The acromial end of the clavivle articulates withi which structure?
Acromion process of the scapula
The lateral third of the clavicle is flattened and concave anteriorly. T/F
T
The scapulothoracic joint is an anatomical joint. T/F
F
It is a physiological joint in which movement occurs between the scapula and associated muscles of the thoracic wall
The scapula transmits shock (traumatic impacts) from the upper limb to the axial skeleton. T/F
T
Being a long bone, the clavicle has a medullary cavity (marrow). T/F
F
Although designed as a long bone, it has no medullary cavity, and instead consists of spongy (trabecular) bone with a shell of compact bone.
The superior surface of the clavicle is rough. T/F
F
It is smooth.
Which muscle overlies the superior surface of the clavicle?
Platysma
The inferior surface of the clavicle is rough because strong ligaments bind to it to the 1st rib near its sternal end and suspend the scapula from its acromial end. T/F
