Verified step by step guidance

Understand the anatomical position: The anatomical position is a standard reference point in anatomy where the body is upright, facing forward, with arms at the sides and palms facing forward. This ensures consistent terminology.

Identify the term 'nares': The nares are the external openings of the nose, commonly referred to as nostrils. They allow air to enter the nasal cavity.

Determine the structure that divides the nares: The nares are separated by a structure called the nasal septum, which is a vertical partition within the nasal cavity.

Break down the components of the nasal septum: The nasal septum is primarily composed of the perpendicular plate of the ethmoid bone, the vomer bone, and cartilage. These structures work together to form the division.

Eliminate incorrect options: The ethmoid bone is part of the nasal septum but does not solely divide the nares. The hard palate forms the roof of the mouth, and the nasal conchae are bony structures within the nasal cavity that do not divide the nares. Therefore, the correct answer is the nasal septum.
