Pedicle:
Each antler grows from an attachment point on the skull called a pedicle. While an antler is growing, it is covered with highly vascular skin called velvet, which supplies oxygen and nutrients to the growing bone. [Wikipedia article on Antlers]
Seen on the Rivermen Rod & Gun blog at the very bottom of this page:
This deer had some very uncomfortable days until he was harvested by this hunter. It is obvious that there was a fight during the rut and this deer ended up with an extra antler (embedded below the eye). You can see that the antler from the attacking deer was broke off below the base of the antler as there is still blood on the pedicel [sic]. That takes a tremendous amount of pressure.
