transverse diameter

In this way, the transverse diameter is expanded and the lungs can fill.

Its inlet is either slightly oval, with a greater transverse diameter, or round.

The transverse diameter of the pelvic inlet measures 13.5 cm.

The biparietal (9.5 cm), the greatest transverse diameter of the head, which extends from one parietal boss to the other.

It is the more prominent and is the broader both in its antero-posterior and transverse diameters.

It is somewhat cuboid in form, but its transverse diameter is greater than its antero-posterior (front to back).

Anthropoid: the widest transverse diameter is less than the anteroposterior (obstetrical) diameter.

Contraction of this muscle aids in exertional expiration by decreasing the transverse diameter of the thoracic cage.

It is broader, and extends farther upward, on the volar than on the dorsal aspect, and is longer in the antero-posterior than in the transverse diameter.

Cardio-thoracic ratio is the "transverse diameter of the heart, as determined by x-ray examination, compared with that of the thoracic cage, used to help determine enlargement of the heart."

Its transverse diameter is greater than its antero-posterior diameter and its thick collateral ligaments are tight in all positions during flexion, contrary to those in the metacarpophalangeal joint.

In defining an ellipse, the short (vertical) diameter is known as the conjugate diameter, and the long (horizontal) diameter-perpendicular, or "transverse", to the conjugate-is the transverse diameter.

Biomechanical factors of pregnancy that are shown to be associated with low back pain of pregnancy include abdominal sagittal and transverse diameter and the depth of lumbar lordosis.

It is defined as the ratio of the transverse diameter (the horizontal distance of the inside of the ribcage) and the anteroposterior diameter (the shortest distance between the vertebrae and sternum).

The transverse diameter of a normal meniscus is approximately 10 to 11 mm; therefore a normal meniscus body will be visible on only 2 slices of a MR with 4-5-mm sagittal slices.

It is larger than the upper extremity of femur, is somewhat cuboid in form, but its transverse diameter is greater than its antero-posterior; it consists of two oblong eminences known as the condyles.

After 13 weeks of gestation, the fetal age may be estimated using the biparietal diameter (the transverse diameter of the head), the head circumference, the length of the femur, the crown-heel length (head to heel), and other fetal parameters.

The lateral condyle is the more prominent and is the broader both in its antero-posterior and transverse diameters, the medial condyle is the longer and, when the femur is held with its body perpendicular, projects to a lower level.

The distance between antipodal points on the ellipse, or pairs of points whose midpoint is at the center of the ellipse, is maximum along the major axis or transverse diameter, and a minimum along the perpendicular minor axis or conjugate diameter.

At full term, the fetal bitrochanteric diameter (the distance between the outer points of the hips) is about the same as the biparietal diameter (the transverse diameter of the skull)-simply put the size of the hips are the same as the size of the head.
