| lower oesophageal sphincter | <anatomy> A muscular sphincter located at the junction of the oesophagus and the stomach. On closure the lower oesophageal sphincter prevents the back wash (reflux) of stomach acid into the oesophagus where it may damage the mucosa. See: gastrooesophageal reflux disease. (16 Mar 1998) |
| lower respiratory tract | <anatomy> The trachea, bronchi, and lungs. (09 Oct 1997) |
| lower respiratory tract smear | A group of cytologic specimens containing material from the lower respiratory tract and consisting mainly of sputum (spontaneous, induced) and material obtained at bronchoscopy (aspirated, lavaged, brushed); used for cytologic study of cancer and other diseases of the lungs. Synonym: bronchoscopic smear, sputum smear. (05 Mar 2000) |
| Lower, Richard | <person> English anatomist and physiologist, 1631-1691. See: Lower's ring, Lower's tubercle. (05 Mar 2000) |
| lower segment cesarian section | A Cesarian section in which the surgical incision (cut) is made in the lower segment of the uterus. (12 Dec 1998) |
| Lower's ring | One of four fibrous rings that surround atrioventricular and arterial orifices of the heart, providing attachment for the valve leaflets and maintaining patency of the orifice. As part of the fibrous skeleton of the heart, the fibrous rings also provide origin and insertion for the myocardium. Synonym: annulus fibrosus cordis, annulus fibrosus, coronary tendon, fibrous ring, Lower's ring. (05 Mar 2000) |
| Lower's tubercle | The slight projection on the wall of the right atrium between the orifices of the venae cavae. Synonym: tuberculum intervenosum, Lower's tubercle. (05 Mar 2000) |
| lower uterine segment | The inferior portion or isthmus of the uterus, the lower extremity of which joins with the cervical canal and, during pregnancy, expands to become the lower part of the uterine cavity. (05 Mar 2000) |
| lower uterine segment cesarean section | A cesarean section in which the uterus is entered in its lower segment by a transperitoneal approach. (05 Mar 2000) |
| acromial end of clavicle | The flattened lateral end of the clavicle that articulates with the acromion and is anchored to the coracoid process by the conoid and trapezoid ligaments. Synonym: extremitas acromialis claviculae, acromial end of clavicle. (05 Mar 2000) |
| blunt-end | Refers to double-stranded DNA in which there are no unpaired bases at the end. (05 Mar 2000) |
| blunt-end DNA | <molecular biology> A fragment of a DNA molecule in which the ends of both strands are even with each other rather than one strand being longer than the other. (09 Oct 1997) |
| blunt-end ligation | A lab technique to join together two pieces of blunt-end DNA, such as an insert into a cloning vector, which requires the enzyme ligase because there are no single-stranded overhanging ends for the attachment to form more spontaneously, by itself. (09 Oct 1997) |
| by-end | Private end or interest; secret purpose; selfish advantage. Alternative forms: bye-end. (20 Mar 1998) |
