The sense of smell, or olfaction, begins in a small area on the roof of the nasal cavity , which is covered in specialized mucosa. From there, the olfactory nerve transmits the sensory perception of smell via the olfactory pathway. This pathway is composed of the olfactory cells and bulb,...
The External Nose (+ Diagram) Structure ( skin , bony components, nasal cartilage ) The external nose is pyramidal in shape. The nose consists of: A proximal nasal root The apex at the tip of the nose 2 inferior nares /nostrils (openings to the nasal cavity) Skin : The skin over...
The olfactory nerve doesn’t have a specific nucleus of its own. Instead its cell bodies are found in the olfactory area-the nasal mucosa that covers the roof of the nasal cavity. *Note that there is an ongoing discussion about the modality of the olfactory nerve. Some authors say it’...
The head of the nucleus contributes to the lateral wall of the lateral ventricle. The tail of the caudate nucleus forms the roof of the inferior horn of the lateral ventricle. It arches over the ventral surface of the thalamus, enters the temporal lobe and terminates by connecting with the ...
The triangular apex is directed distally and is created by the joining of two borders. The cubital fossa possesses a floor and a roof. Many structures traverse this region. Medial and lateral borders of the cubital fossaWhat Is in the Antecubital Fossa? Clinical Significance of the Ante...

Sinuses are formed by the erosion of the nasal cavity into the surrounding bone during fetal development. Therefore, all sinuses drain into the nasal cavity. The openings to the sinuses are located in the roof and sidewalls of the nose....
Structural measurements were analysed regarding their orientation thanks to a classical π-diagram approach for folds and the structural measurements of faults’ kinematics were grouped and inverted for paleostress orientation, using the WinTensor structural software (Delvaux,1993) and the Right Dihedra ...
