| epicondylus lateralis ossis femoris | The epicondylus located proximal to the lateral condyle. Synonym: epicondylus lateralis ossis femoris, lateral femoral tuberosity. (05 Mar 2000) |

| epicondylus medialis ossis femoris | The epicondylus located proximal to the medial condyle. Synonym: epicondylus medialis ossis femoris, medial femoral tuberosity. (05 Mar 2000) |
| trochlea femoris | The groove formed anteriorly between the anterosuperior portions of the femoral condyles that accommodates the patella. Synonym: facies patellaris femoris, trochlea femoris. (05 Mar 2000) |
| facies patellaris femoris | The groove formed anteriorly between the anterosuperior portions of the femoral condyles that accommodates the patella. Synonym: facies patellaris femoris, trochlea femoris. (05 Mar 2000) |
| facies poplitea femoris | The posterior surface of the lower end of the femur between the diverging lips of the linea aspera. Synonym: facies poplitea femoris, planum popliteum, popliteal plane of femur. (05 Mar 2000) |
| fovea capitis ossis femoris | A depression on the extremity of the head of the femur giving attachment to the ligamentum teres femoris. Synonym: fovea capitis ossis femoris, pit of head of femur. (05 Mar 2000) |
| ligamentum capitis femoris | A flattened ligament that passes from the fovea in the head of the femur to the borders of the acetabular notch (transverse acetabular ligament); developmentally, an artery passes to the head of the femur with the ligament which may or may not persist into adulthood; the ligament does not contribute to the integrity of the joint or control movements there. Synonym: ligamentum capitis femoris, ligamentum teres femoris, round ligament of femur. (05 Mar 2000) |
| ligamentum teres femoris | A flattened ligament that passes from the fovea in the head of the femur to the borders of the acetabular notch (transverse acetabular ligament); developmentally, an artery passes to the head of the femur with the ligament which may or may not persist into adulthood; the ligament does not contribute to the integrity of the joint or control movements there. Synonym: ligamentum capitis femoris, ligamentum teres femoris, round ligament of femur. (05 Mar 2000) |
| linea intercondylaris femoris | A faint transverse ridge separating the floor of the intercondylar fossa from the popliteal surface of the femur; it affords attachment to the posterior portion of the articular capsule of the knee. Synonym: linea intercondylaris femoris. (05 Mar 2000) |
| abdominal external oblique muscle | <anatomy, muscle> Origin, fifth to twelfth ribs; insertion, anterior half of lateral lip of iliac crest, inguinal ligament, and anterior layer of the rectus sheath; action, diminishes capacity of abdomen, draws thorax downward; nerve supply, thoracoabdominal nerves. Synonym: musculus obliquus externus abdominis, abdominal external oblique muscle. (05 Mar 2000) |
| abdominal internal oblique muscle | <anatomy, muscle> Origin, iliac fascia deep to lateral part of inguinal ligament, anterior half of crest of ilium, and lumbar fascia; insertion, tenth to twelfth ribs and sheath of rectus; some of the fibres from inguinal ligament terminate in the conjoint tendon; action, diminishes capacity of abdomen, flexes lumbar vertebral column (bends thorax forward); nerve supply, lower thoracic. Synonym: musculus obliquus internus abdominis, abdominal internal oblique muscle. (05 Mar 2000) |
| abdominal muscle deficiency syndrome | <syndrome> Congenital absence (partial or complete) of abdominal muscles, in which the outline of the intestines is visible through the protruding abdominal wall; in males, genitourinary anomalies (urinary tract dilation and cryptorchidism) are also found; genetics unclear. (05 Mar 2000) |
| abductor digiti minimi muscle of foot | Origin, lateral and medial processes of calcanean tuberosity; insertion, lateral side of proximal phalanx of fifth toe; action, abducts and flexes little toe; nerve supply, lateral plantar nerve. Synonym: musculus abductor digiti minimi pedis, abductor muscle of little toe, musculus abductor digiti quinti. (05 Mar 2000) |
| abductor digiti minimi muscle of hand | Origin, pisiform bone and pisohamate ligament; insertion, medial side of base of proximal phalanx of the little finger; action, abducts and flexes little finger; nerve supply, ulnar. Synonym: musculus abductor digiti minimi manus, abductor muscle of little finger, musculus abductor digiti quinti. (05 Mar 2000) |
| abductor muscle | <anatomy> Any muscle used to pull a body part away from the midline of the body. For example, the abductor leg muscles serve to spread the legs. The opposite of abductor is adductor. (12 Dec 1998) |
