Chapter 7, Problem 4a
Mark the following statements as true or false. If a statement is false, correct it to make a true statement.
a. The four paranasal sinuses are the frontal, parietal, sphenoidal, and mandibular sinuses.
Verified step by step guidance1
Step 1: Begin by identifying the anatomical structures mentioned in the statement. The paranasal sinuses are air-filled cavities located within certain bones of the skull. Their primary function is to lighten the skull, produce mucus, and enhance voice resonance.
Step 2: Recall the names of the four paranasal sinuses. They are the frontal sinus, maxillary sinus, sphenoidal sinus, and ethmoidal sinus. Compare these names to the ones listed in the statement.
Step 3: Analyze the statement provided. The statement lists the frontal, parietal, sphenoidal, and mandibular sinuses. Note that 'parietal' and 'mandibular' are incorrect because there are no paranasal sinuses associated with the parietal or mandibular bones.
Step 4: Correct the false statement. Replace 'parietal' with 'ethmoidal' and 'mandibular' with 'maxillary' to accurately reflect the names of the four paranasal sinuses.
Step 5: Finalize the corrected statement: 'The four paranasal sinuses are the frontal, ethmoidal, sphenoidal, and maxillary sinuses.'

Key Concepts
Here are the essential concepts you must grasp in order to answer the question correctly.
Paranasal Sinuses
Paranasal sinuses are air-filled spaces located within the bones of the skull that are connected to the nasal cavity. They include four main pairs: the frontal, maxillary, ethmoid, and sphenoid sinuses. These sinuses play a role in reducing skull weight, producing mucus, and enhancing voice resonance.

Overview of Sinuses
Anatomical Accuracy
Anatomical accuracy refers to the correct identification and naming of body structures. In the context of the question, it is crucial to recognize that the paranasal sinuses listed in the statement are incorrect, as the parietal and mandibular sinuses do not exist. Understanding the correct anatomical terms is essential for accurate communication in medical and anatomical discussions.

True or False Statements
True or false statements are assertions that can be evaluated for their validity. In this exercise, students must determine the truthfulness of the provided statement about paranasal sinuses. Correcting false statements involves not only identifying inaccuracies but also providing the correct information, which reinforces learning and comprehension of anatomical structures.
