Mature red deer stag, Denmark Red deer at the beginning of the growing season. Antlers are extensions of an animal's skull found in members of the Cervidae (deer) family.Antlers are a single structure composed of bone, cartilage, fibrous tissue, skin, nerves, and blood vessels.
The lacrimal bone also contains the nasolacrimal duct. The superior bony margin of the orbital rim, otherwise known as the orbital process, is formed by the frontal bone. [7] The roof (superior wall) is formed primarily by the orbital plate frontal bone, and also the lesser wing of sphenoid near the apex of the orbit. The orbital surface ...
The preorbital gland is a paired exocrine gland found in many species of artiodactyls, which is homologous to the lacrimal gland found in humans. These glands are trenchlike slits of dark blue to black, nearly bare skin extending from the medial canthus of each eye.
A deer (pl.: deer) or true deer is a hoofed ruminant ungulate of the family Cervidae (informally the deer family). Cervidae is divided into subfamilies Cervinae (which includes, among others, muntjac , elk (wapiti), red deer , and fallow deer ) and Capreolinae (which includes, among others reindeer (caribou), white-tailed deer , roe deer , and ...
The leaf window is also known as a fenestra, [5] and is a translucent structure that transmits light, as in Fenestraria. Examples of fenestrate structures in the fungal kingdom include the symmetrically arranged gaps in the indusium ("skirt") of the mushroom Phallus duplicatus , [ 6 ] and the thallus of the coral lichen Pulchrocladia retipora .
The supraorbital foramen is a small groove at superior and medial margin of the orbit in the frontal bone. It is part of the frontal bone of the skull. [2] It arches transversely below the superciliary arches and is the upper part of the brow ridge. It is thin and prominent in its lateral two-thirds, but rounded in its medial third. [3]
In anatomy, the zygomatic arch, or cheek bone, is a part of the skull formed by the zygomatic process of the temporal bone (a bone extending forward from the side of the skull, over the opening of the ear) and the temporal process of the zygomatic bone (the side of the cheekbone), the two being united by an oblique suture (the zygomaticotemporal suture); [1] the tendon of the temporal muscle ...
The Harderian gland is a gland found within the eye's orbit that occurs in tetrapods (reptiles, amphibians, birds and mammals) that possess a nictitating membrane. [ 1 ] The gland can be compound tubular or compound tubuloalveolar , and the fluid it secretes ( mucous , serous or lipid ) varies between different groups of animals.
