Turbinate bone of animals

Turbinate bone of animals is present in the nose and remain covered by soft tissue.

Turbinate bone of Ox

Turbinate bone of Ox are delicate scroll like bones two on either side, attached to the lateral walls of the nasal cavity.

Each is a thin cribriform lamina covered on both sides by mucous membrane in the fresh state.

The dorsal turbinate is the smaller of the two.

The medial face is separated from the septum nasi by narrow space-the common nasal meatus. The lateral face is attached to the turbinate crest of the nasal bone.

The posterior part joins the cribriform plate and the lateral mass of ethmoid. It communicates with the frontal sinus in the dry skull and this opening is closed by mucous membrane in fresh state.

Between the dorsal turbinate bone and the roof of the nasal cavity (nasal bone) is the dorsal nasal meatus.

Between the dorsal and ventral turbinate is the middle nasal meatus. The ventral turbinate is larger than the dorsal.

It is attached to the turbinate of the maxilla by a basal lamella. The latter divides at its inner edge into two plates, which is rolled in opposite directions to enclose two cavities. The upper cavity opens into the middle nasal meatus while the lower opens into the ventral nasal meatus.

Turbinate bone of Horse

The dorsal turbinate is longer and larger in the Turbinate bone of Horse. Each turbinate has an anterior coiled part and posterior curved portion.

The coiled parts of the two bones are rolled towards the septum and each other.

Turbinate bone of Dog

The Turbinate bone of Dog are richly convoluted. However, the anterior part of the dorsal bone form a simple curved plate overhang the ventral bone. 

The posterior part of the dorsal bone is not clearly separated from the lateral mass of ethmoid. The ventral bone is as in the ox; but has additional tertiary lamellae.

Turbinate bone of Fowl

Turbinate bone of Fowl are three in number-anterior, middle and posterior. 

The middle is the largest and posterior is the smallest.
