| tabes dorsalis | A condition that results from the destruction of the dorsal columns in the spinal cord, normally responsible for position sense. Loss of position sense causes severe gait and leg ataxia (balance and motor control problems). Tabes dorsalis can be the result of spinal cord injury or infection (syphilis). Results in a staggering wide-based gait, postural instability, pain and paresthesias. (27 Sep 1997) |

| ramus | A standard medical dictionary contains over 13 pages full of entries to the word ramus. Why? because ramus in latin means a branch and all sorts of anatomic items such as blood vessels and nerves quite naturally have branches. So, for example, medicine is plagued with the likes of the ramus acetabularis arteriae circumflexae femoris medialis which is simply the branch of an artery that goes to the acetabulum (the socket) of the hip joint. (12 Dec 1998) |
| ramus acetabularis | An arterial branch that supplies the acetabulum; two arteries, the obturator and the medial femoral circumflex, have such branches. Synonym: ramus acetabularis, acetabular artery, arteria acetabuli. (05 Mar 2000) |
| ramus acromialis arteriae suprascapularis | <anatomy, artery> Branch of suprascapular artery which pierces the origin of the trapezius muscle to run to the acromion; anastomoses, acromial branch of thoracoacromial artery. Synonym: ramus acromialis arteriae suprascapularis. (05 Mar 2000) |
| ramus acromialis arteriae thoracoacromialis | <anatomy, artery> A branch of the thoracoacromial artery that runs over the coracoid process and under the deltoid muscle. Synonym: ramus acromialis arteriae thoracoacromialis, acromial artery. (05 Mar 2000) |
