The nasal cavity is divided into right and left halves by the ______.Multiple choice question.nasal conchaenasal septumnasolacrimal canalparanasal sinuses

Break Down the Problem

1. Identify the structure that divides the nasal cavity.
2. Analyze the options provided to determine the correct answer.

Relevant Concepts

• The nasal cavity is divided into two halves, and the structure responsible for this division is important in anatomy.

Analysis and Detail

1. Nasal Conchae: These are bony structures that protrude into the nasal cavity but do not divide it.
2. Nasal Septum: This is the structure that separates the left and right sides of the nasal cavity, made up of bone and cartilage.
3. Nasolacrimal Canal: This canal is responsible for draining tears from the eyes into the nasal cavity but does not divide it.
4. Paranasal Sinuses: These are air-filled spaces and do not play a role in dividing the nasal cavity.

Verify and Summarize

The only structure that physically divides the nasal cavity into left and right halves is the nasal septum.

Final Answer

The nasal cavity is divided into right and left halves by the nasal septum.
