Question

What do we mean by notochord,ventral and dorsal?

Answer 1

• Notochord is a mesodermally derived rod-like structure formed on the dorsal side during embryonic development in some animals. Animals with notochord are called chordates and those animals which do not form this structure are called non-chordates.

• Function: The main function of notochord is to support the body. As the embryo grows it becomes a part of the true backbone or vertebral column.

• Ventral means front or anterior of any structure. A body part present in a ventral direction is mentioned as ventrally located. (like chest, Abdomen etc of human body.)
• Dorsal means back or posterior of any structure. A body part present in a dorsal direction is mentioned as dorsally located. (like back,buttocks etc of human body)
