The following is a striking example of the evil of clavicular breathing.
The clavicular and abdominal air cells are perhaps the most interesting.
The sternal, and probably a portion of the clavicular attachment of the right sterno-mastoid, must then be cautiously divided.
Hence the clavicular arch may be lost, though the collar bones are retained in man.
The clavicular portion of the pectoralis major must then be divided right across its fibres, which will retract.
The sterno-cleido mastoid, whose inferior attachments we mentioned above, cannot have a clavicular portion.
Thus the clavicular arch is placed in front of the scapular arch.
"collarbone," 1610s, from Middle French clavicule "collarbone" (16c.), also "small key," from Medieval Latin clavicula "collarbone" (used c.980 in a translation of Avicenna), special use of classical Latin clavicula, literally "small key, bolt," diminutive of clavis "key" (see slot (n.2)); in the anatomical sense a loan-translation of Greek kleis "key, collarbone." So called supposedly from its function as the "fastener" of the shoulder. Related: Clavicular.
clavicle clav·i·cle (klāv'ĭ-kəl)
Either of two slender bones that extend from the manubrium of the sternum to the acromion of the scapula. Also called collarbone.
