Proboscis

DA: 180




Developmental anomaly information

Definition: The proboscis, (a human nose, especially a prominent one) represents the anterosuperior part of the normal nasal cavity developed in the absence of median components. The skeleton of the proboscis is formed by the nasal capsule. The base of the proboscis lies in the floor of the anterior cranial fossa filling an extended ethmoidal notch and contributing to the roof of the median orbit anterior to the fused lesser wings of sphenoid. The cavity of the proboscis is lined with squamous epithelium, respiratory and olfactory mucosa. Olfactory fibres pass from the proboscis into the extradural space of the ethmoidal notch forming a collection of tissue similar to the inferior layer of the normal olfactory bulb.
