Comparative embryology of the carotid body

A preliminary anatomical study on carotid body of Makouei sheep

The carotid is a small mass of chemoreceptor's and sustentacular cells that detects changes in the composition of the arterial blood. The aim of the present study was to identify the size, color, location, blood and nerve supply of the carotid body in Makouei sheep. Fourteen heads of sheep from both sexes were collected from Urmia public slaughter-house. The exact situation and nerve supply of ...

A treasure house of comparative embryology.

The Embryo Collection of the Hubrecht Laboratory is a treasure house of comparative embryology. It is the largest and most important collection of its kind in the world, and consists of thousands of vertebrate embryos stored in alcohol, or prepared as histological sections. Many elusive species are included in the collection, some represented by complete developmental series. The accompanying a...

Modularity, comparative embryology and evo-devo: developmental dissection of evolving body plans.

Modules can be defined as quasi-autonomous units that are connected loosely with each other within a system. A need for the concept of modularity has emerged as we deal with evolving organisms in evolutionary developmental research, especially because it is unknown how genes are associated with anatomical patterns. One of the strategies to link genotypes with phenotypes could be to relate devel...
