| AXD | axillary dissection |
| axillary cavity | <anatomy> The underarm area. (16 Dec 1997) |
|---|---|
| axillary dissection | <procedure, surgery> Surgical removal of lymph nodes from the armpit. This tissue is then sent to the pathologist to determine if the breast cancer has spread outside of the breast. The number of nodes dissected varies during surgery. (02 Jan 1998) |
| axillary fascia | The fascia that forms the floor of the axilla. It is continuous with the pectoral and clavipectoral fascia anteriorly, with the brachial fascia laterally, and with the fascia of the latissimus dorsi and serratus anterior muscles posteriorly and medially. Synonym: fascia axillaris. (05 Mar 2000) |
| axillary fold | One of the folds of skin and muscular tissue bounding the axilla anteriorly and posteriorly. Synonym: plica axillaris. (05 Mar 2000) |
| axillary fossa | <anatomy> The underarm area. (16 Dec 1997) |
| axillary glands | Numerous nodes around the axillary veins which receive the lymphatic drainage from the upper limb, scapular region and pectoral region (including mammary gland); they drain into the subclavian trunk. Synonym: nodi lymphatici axillares, axillary glands. (05 Mar 2000) |
| axillary hair | Hair of the armpit. (05 Mar 2000) |
| axillary line | See: anterior axillary line, midaxillary line, posterior axillary line. (05 Mar 2000) |
| axillary lymph nodes | Numerous nodes around the axillary veins which receive the lymphatic drainage from the upper limb, scapular region and pectoral region (including mammary gland); they drain into the subclavian trunk. Synonym: nodi lymphatici axillares, axillary glands. (05 Mar 2000) |
| axillary nerve | <anatomy, nerve> Arises from the posterior cord of the brachial plexus in the axilla, passes laterally and posteriorly through quadrangular space with the posterior circumflex artery, winding round the surgical neck of the humerus to supply the deltoid and teres minor muscles, terminating as the superior lateral brachial cutaneous nerve. Synonym: nervus axillaris, circumflex nerve. (05 Mar 2000) |
| axillary nerve injury | <neurology> A condition involving dysfunction of the axillary nerve which normally supplies the deltoid and teres minor muscles and sensation to the lateral aspect of the shoulder. This condition is a type of peripheral neuropathy that may manifest as the result of a variety of disease processes or injuries. Conditions associated with axillary nerve dysfunction include mononeuritis multiplex, fracture of the humerus, abduction injury to the shoulder, pressure to the armpit from a cast, splint or crutches. Symptoms include numbness over the outer portion of the shoulder, shoulder weakness and difficulty lifting arm or objects over your head. An EMG, nerve conduction study or muscle biopsy can be helpful in making the diagnosis. Recovery is generally spontaneous if the underlying cause can be corrected and shoulder mobility is preserved. Corticosteroid injections may be indicated in some instances. (02 Jan 1998) |

| axillary node | <anatomy> The lymph nodes in the axilla (underarm) that are cut out and examined during surgery to see if the cancer has spread past the breast. The number of nodes in this area varies. (09 Oct 1997) |
| axillary plexus | A lymphatic plexus formed of the lymph nodes, with their afferent and efferent vessels, in the axilla. Synonym: plexus axillaris. (05 Mar 2000) |
| axillary region | The region of the axilla, including the axillary fossa. Synonym: regio axillaris. (05 Mar 2000) |
