Endotome

The tegmens are indeed similar and the composition of the cups are about the same but the organisation of the arms of Thamnocrinus with pronounced endotome branching and completely fixed main arm trunk must have differed considerably from Stamnocrinus devonicus.

Recently, lineage tracing somite cells using the Kaede protein and Cre/loxP technology revealed that a subset of somite cells termed endotome give rise to angioblasts that colonize the DA (Nguyen et al. 2014).

Having perforated, he then passes into the cranium an endotome, which consists of scissors having short curved, very strong blades, worked by long, powerful crossing handles, resembling Nägele's perforator;

MATTEI'S ENDOTOME is a powerful instrument working on a scissors-joint; the shanks are double curved, so that by approximating the handles the curved blades can be brought together

Mattei uses strong scissors which he calls endotomes; Lazarewitch uses an instrument which is at once a sector and a tractor.

The endotome is introduced through the left upper quadrant port; the blade advanced out of its sheath in its entirety.

2.0–3.0 mm retractable myotomy knife (arthrotomy knife or sheathed knife: endotome).

Endotome or diathermy hook is placed through the right incision, and the pylorus is incised in its avascular plane from the prepyloric vein well into the gastric antrum (Figure 52.8).
