| oblique diameter | A measurement across the pelvic inlet from the sacroiliac joint of one side to the opposite iliopectineal eminence. Synonym: diameter obliqua. (05 Mar 2000) |
|---|---|
| obstetric conjugate diameter | The diameter that represents the shortest diameter through which the head must pass in descending into the superior strait and measures, by means of X-ray, the distance from the promontory of the sacrum to a point on the inner surface of the symphysis a few millimeters below its upper margin. Synonym: obstetric conjugate diameter. (05 Mar 2000) |
| occipitofrontal diameter | The diameter of the foetal head from the external occipital protuberance to the most prominent point of the frontal bone in the midline. (05 Mar 2000) |
| occipitomental diameter | The diameter of the foetal head from the external occipital protuberance to the midpoint of the chin. (05 Mar 2000) |
| total end-diastolic diameter | Cross sectional diameter of the left ventricle including the septum and posterior wall thicknesses in diastole. (05 Mar 2000) |
| total end-systolic diameter | Cross sectional diameter of the left ventricle including the septum and posterior wall thicknesses in systole. (05 Mar 2000) |
| trachelobregmatic diameter | The diameter of the foetal head from the middle of the anterior fontanelle to the neck. (05 Mar 2000) |
| transverse diameter | The transverse diameter of the pelvic inlet, measured between the terminal lines. Synonym: diameter transversa. (05 Mar 2000) |
| external conjugate diameter | The distance in a straight line between the depression under the last spinous process of the lumbar vertebrae and the upper edge of the pubic symphysis. Synonym: Baudelocque's diameter, external conjugate diameter. (05 Mar 2000) |
| zygomatic diameter | The extreme breadth of the skull at the zygomatic arches. (05 Mar 2000) |
| annulus fibrosus of intervertebral disc | The ring of fibrocartilage and fibrous tissue forming the circumference of the intervertebral disc; surrounds the nucleus pulposus, which is prone to herniation when the annulus fibrosus is compromised. Synonym: annulus fibrosus disci intervertebralis, annulus fibrosus, fibrous ring of intervertebral disc, fibrous ring. (05 Mar 2000) |
| articular disc | A plate or ring of fibrocartilage attached to the joint capsule and separating the articular surfaces of the bones for a varying distance, sometimes completely; it serves to adapt two articular surfaces that are not entirely congruent. Synonym: discus articularis, articular disk, fibrocartilago interarticularis, fibroplate, interarticular fibrocartilage, intra-articular cartilage. (05 Mar 2000) |
| articular disc of acromioclavicular joint | The articular disk of fibrocartilage usually found between the acromial end of the clavicle and the medial border of the acromion. Synonym: discus articularis acromioclavicularis, acromioclavicular disk, Weitbrecht's cartilage. (05 Mar 2000) |
| articular disc of distal radioulnar joint | The disk that holds together the distal ends of the radius and ulna; it is attached by its apex to a depression between the styloid process and distal surface of the head of the ulna, and by its base to the ridge separating the ulnar notch from the carpal surface of the radius. Synonym: discus articularis radioulnaris, radioulnar disk, radioulnar articular disk, triangular cartilage, triangular disk of wrist, triquetrous cartilage. (05 Mar 2000) |
| articular disc of sternoclavicular joint | The fibrocartilaginous disk that subdivides the sternoclavicular joint into two cavities. Synonym: discus articularis sternoclavicularis, sternoclavicular disk, sternoclavicular articular disk. (05 Mar 2000) |
