"Yes, dragons lay eggs and all birds have a uterus and that 'female part'.

Now...let's see...."

He points his wand at the board....



"There are three membranes that make up the wing: the primary mainsail, the secondary mainsail and the spar mainsail. The primary mainsail stretches from the dorsal spine and shoulder, stretching to the inner bone and forms that largest of the three membranes that comprises the wing. It is this membrane that supports the majority of the body weight. The secondary mainsail extends from the inner bone to the mid bone, whilst the third mainsail, the spar mainsail, runs from the mid bone to the spar bone. As well as providing support of the body's weight, these latter two mainsails provide manoeuvrability. The membranes can be manipulated by the tendons attached to the various joints, to provide movement in both the horizontal and vertical planes. The outermost tip of the spar mainsail is termed the 'finger sail' since it is able to function almost independently of all the other mainsails.
The wing membranes are nearly translucent in Dragons, although thicker over the bones and muscle attachment points. However, they are significantly stronger than they appear. Additional support of the primary mainsail is provided by a number of cartilages which extend from the arm and finger joint towards the trailing edge and referred to as 'batten ribs'.
