When examined there was slight fulness over an area roughly circular and about 2-1/2 inches in extent, of which the sterno-clavicular joint lay just within the centre.
The removal of diseased supra-clavicular glands is not to be lightly undertaken, as difficulties are liable to ensue in connection with the thoracic duct, the pleura, or the junction of the subclavian and internal jugular veins.
The first symptom noticed is tenderness in the supra-clavicular region, the child crying when this part is touched or the arm is moved.
The prognosis is less favourable in the supra-clavicular lesions than in those below the clavicle, which nearly always recover without surgical intervention.
The integrity of the coraco-clavicular ligaments prevents any marked drooping of the shoulder.
The sternal head of the sterno-mastoid is always markedly shortened, and stands out as a tight cord; sometimes the clavicular head is also prominent.
The circumscribed lipoma usually occurs over the nape of the neck or in the supra-clavicular region.
The parts above this level retain sensation, as they are supplied by the supra-clavicular nerves which are derived from the fourth cervical segment (Fig.
Immediately lateral to the supra-sternal notch, the sterno-clavicular articulation may be felt, the large end of the clavicle projecting to a varying degree beyond the margins of the small and shallow articular surface on the sternum.
In rare cases the fracture passes into the acromio-clavicular joint, and is associated with dislocation of the clavicle.
The knee, the wrist, the carpal, the tarsal, and the clavicular joints depend for their stability almost entirely on the strength of their ligaments.
As a rule, the deformity is insignificant, except when the costo-clavicular ligament is torn, in which case the medial end of the distal fragment is tilted up by the weight of the arm.
It differs from the other injuries in this region in being more easily reduced and retained in position, the epiphysis lying entirely within the limits of the articular capsule of the sterno-clavicular joint.
When the fistula is complete, the external opening is situated a short distance above the sterno-clavicular joint.
The sternal fragment may be slightly drawn upwards by the clavicular fibres of the sterno-mastoid, while the acromial fragment falls by the weight of the arm, and the fragments usually overlap to the extent of about half an inch.
When close to the sternal end, this fracture may simulate a dislocation of the sterno-clavicular joint or a separation of the clavicular epiphysis.
I have characterized clavicular breathing as an upward perpendicular force, ugly and only partially effective.
It enlarges the chest cavity more than does either the clavicular or the diaphragmatic method; but does not enlarge it to its full capacity.
But as clavicular breathing acts only on the upper ribs, it causes only the upper part of the chest to expand, and so actually circumscribes the space within which and the extent to which the lungs can be inflated.
Moreover, as in all errors of method in voice-teaching, there is a precise physiological reason why clavicular breathing is incorrect.
The linear guide for the carotid is represented by a line drawn from the sterno-clavicular junction to a point between the angle of the jaw and the lobe of the ear.
To do so the skin is cut on either side from the sterno-clavicular junction to a point where the ninth rib joins to its costal cartilage.
The cut is then made from one sterno-clavicular junction to the other following the supra-sternal notch.
The line of the common and the external carotid arteries may be marked by joining the sterno-clavicular articulation to the angle of the jaw.
The clavicular portion of the pectoralis major must then be divided right across its fibres, which will retract.
The sternal, and probably a portion of the clavicular attachment of the right sterno-mastoid, must then be cautiously divided.
The sternal attachment of the sterno-mastoid must then be cautiously divided, as also part or the whole of its clavicular attachment, according as room is required.
The innominate artery divides into the right subclavian and right carotid exactly behind the sterno-clavicular articulation.
About the presence in typical forms of the coraco-scapular plate and two independentclavicular bars all authors are agreed.
The ventral ends of the two clavicular bars enlarge to form two longitudinally placed plates, which unite together and ossify as the interclavicle.
The scapulo-coracoid plate soon becomes cartilaginous, while at the same time the clavicular bar ossifies directly from the membranous state.
Thus the clavicular arch is placed in front of the scapular arch.
The air cell termed clavicular sends a process outward towards the arm, along with the blood vessels which supply the arm.
The clavicular and abdominal air cells are perhaps the most interesting.
Hence the clavicular arch may be lost, though the collar bones are retained in man.
The dotted line C shows the retraction of the diaphragm and of the abdominal muscles in forced clavicular inspiration.
In scientific works the first is called diaphragmatic or abdominal,[B] the second lateral or costal, and the third clavicular or scapular breathing.
The origin is also from the manubrium and the anterolateral portion of the proximal half of the coracoid and to a slight extent from the sterno-coraco-clavicular membrane adjacent to the manubrium.
The origin is from the manubrium and from approximately the posterior half of the coracoid and on the medial and dorsal surface of that bone, and the medial side of the sterno-coraco-clavicular membrane adjacent to the coracoid.
The pectoral girdle is formed of two parts, one endoskeletal and cartilaginous, corresponding with the pectoral girdle of Elasmobranchs, and one exoskeletal and formed of membrane bones, corresponding with the clavicular bones of Teleosteans.
The exact locality of the artery in this part of its course would be indicated by a finger's breadth external to the clavicular attachment of the sterno-mastoid muscle.
Clavicular attachment of the sterno-mastoid muscle lying over the internal jugular vein, &c.
The artery passes beneath the clavicle at the middle of this bone, a point which is indicated in most subjects by that cellular interval occurring between the clavicularorigins of the deltoid and great pectoral muscles.
Layer of the cervical fascia lying beneath the clavicular portion of the sterno-mastoid muscle.
Of the four muscles which have partial clavicular origins in man, two are known to us in connection with animals--the great pectoral and the trapezius.
The sterno-cleido mastoid, whose inferior attachments we mentioned above, cannot have a clavicular portion.
The trapezius in man similarly arises in part from the clavicle; for the reasons above indicated its clavicularfasciculi cannot exist in distinct form in the animals which have no clavicle.
By junction of the clavicularand coracal rod on each side arises a left and a right pore, the "jugular pore or jugular gate.
Semantis arises from Archicircus by the production of two pairs of lateral branches from the basilar rod of the sagittal ring, one anterior pair of clavicular rods, and one posterior pair of coracal rods.
The acromio-clavicular articulation is also a gliding joint, but allows a swinging or pendulum movement of the scapula on the clavicle.
The sterno-clavicular articulation, between the presternum and clavicle, is a gliding joint, and allows slight upward and downward and forward and backward movements.
The lower part of this mass is sometimes distinguished as a separate group called the supra-clavicular glands, which drain the back of the neck and receive afferents from the occipital and axillary glands.
The above list will hopefully give you a few useful examples demonstrating the appropriate usage of "clavicular" in a variety of sentences. We hope that you will now be able to make sentences using this word.
