Table 2 Comparison of abductor muscles in the coelacanth (Latimeria), Australian lungfish (Neoceratodus) and mudpuppy (Necturus)
Latimeria chalumnae | Neoceratodus forsteri | Necturus maculosus | ||||||
|---|---|---|---|---|---|---|---|---|
Superficial abductor, secondary bundle « Élévateur superficiel, faiseau secondaire » | O: posterior internal region of the lateral hypophysis |
| Superficial ventromesial abductor (Dorsal and ventral) | O: Ventrolateral face pelvis |
| Pubotibialis (Adductor) (Ventral) | O: lateral edge of the pubic cartilage |
|
I: Base of the 6th and 7th preaxial lepidotrichia | I: Proximal lateral face pelvic fin | I: proximal end of the tibia | ||||||
Superficial ventrolateral abductor (Dorsal and ventral) | O: posterior fascia of the body myotomes |
| Caudofemoralis (Adductor) (Ventral) | O: Caudal vertebra |
| |||
I: Dorsolateral edge proximal axial elements of the fin | I: Proximal end femur | |||||||
Superficial abductor, main bundle « Élévateur superficiel, faiseau principal » | O: Posterior medial face of the lateral hypophysis. |
| Deep ventral abductor depressor (Dorsal and ventral) | O: Ventrolateral process on the pelvis |
| Puboischio femoralis internus (Abductor) (Ventral) | O: Internal surface of the pubic cartilage and ischium |
|
I: Fascia at the base of lepidotrichia. | I: Ventral process at the distal end of the first axial element. | I: along most of the femur | ||||||
Deep abductor “Élévateur profond” | O: lateral sides and base of the anterior pubic ramus I: through tendons to the fascia of the superficial abductor |
| Dorsolateral abductor levator (Dorsal) | O: Swelling on the posterodorsal surface of the pelvisI: Proximal and subsequent fin elements |
| Iliotibialis (Dorsal surface of the thigh) (Abductor) (Dorsal) | O: base of the iliumI: extend over the knee as a tendon, inserts on the tibia |
|
Ilioextensorius (Abductor) (Dorsal) | I: base of the ilium O: extend over the knee as a tendon, inserts on the tibia |
| ||||||
Latimeria chalumnae | Neoceratodus forsteri | Necturus maculosus | ||||||
Pelvic abductor or supinator, second layer, group 5 “Supin, couche 2, groupe 5, Abducteur pelvien” | O: Middle of the mesial hypophysis I: following the preaxial border, inserting directly onto the six first preaxial lepidotrichia |
| Iliofibularis (Abductor) (Dorsal) | O: base of the iliumI: inserts on the fibula |
| |||
Iliofemoralis (Abductor) (Dorsal) | O: base of the iliumI: caudal edge of the femur |
