- 2.
Name the cranial bones.
Correct Answer
Occipital, temporal, parietal, frontal, sphenoid, ethmoindExplanation
The cranial bones are the Occipital, temporal, parietal, frontal, sphenoid, and ethmoid bones. These bones make up the cranium, which is the protective structure that surrounds and supports the brain. The occipital bone is located at the back of the skull, while the temporal bones are on the sides. The parietal bones are on the top and sides of the skull, and the frontal bone is at the front. The sphenoid bone is located in the middle of the skull, and the ethmoid bone is located between the eyes.Rate this question:

Correct Answer
C. 7Explanation
There are 7 facial bones in the human body. These bones include the maxilla, mandible, zygomatic, nasal, lacrimal, palatine, and vomer. These bones are responsible for providing structure and support to the face, as well as protecting important organs such as the eyes and nose.Rate this question:

What two bones form the orbit?
- A.
Frontal and maxilla
- B.
Maxilla and mandible
- C.
Zygomatic and sphenoid
- D.
Sphenoid and ethmoid
Correct Answer
A. Frontal and maxillaExplanation
The orbit is the bony socket in the skull that houses the eyeball. The frontal bone forms the upper part of the orbit, while the maxilla bone forms the lower part. Together, these two bones create the structure of the orbit.Rate this question:

- 5.
Name the facial bones
Correct Answer
Maxilla, mandible, zygomatic, vomer, nasal, inferior nasal conchae, palantineExplanation
The correct answer is a list of facial bones. The facial bones mentioned in the answer are the maxilla, mandible, zygomatic, vomer, nasal, inferior nasal conchae, and palatine bones. These bones are all part of the human skull and contribute to the structure and shape of the face. The maxilla forms the upper jaw, the mandible forms the lower jaw, the zygomatic bones form the cheekbones, the vomer forms the nasal septum, the nasal bones form the bridge of the nose, the inferior nasal conchae are located inside the nasal cavity, and the palatine bones form the roof of the mouth.Rate this question:

What is the function of the cranial bones?
- A.
Head support
- B.
Make the head hard to break
- C.
Keep the brain intact from moving around
- D.
Protect and surround the brain, blood vessels, nerves and connective tissues
Correct Answer
D. Protect and surround the brain, blood vessels, nerves and connective tissuesExplanation
The cranial bones have the function of protecting and surrounding vital structures such as the brain, blood vessels, nerves, and connective tissues. They act as a protective barrier, preventing any damage or injury to these delicate structures. Additionally, the cranial bones help to keep the brain intact and prevent it from moving around, providing stability and support to the head.Rate this question:

What is the function of the facial bones?
- A.
Protect and support entrances to digestive and respiratory system
- B.
Shape the face
- C.
Be able to distinguish between genders
- D.
Support facial features
Correct Answer
A. Protect and support entrances to digestive and respiratory systemExplanation
The facial bones have the important function of protecting and supporting the entrances to the digestive and respiratory systems. They form the structure of the face and provide a framework for the nasal cavity, mouth, and throat. These bones also protect delicate structures such as the eyes and the brain. Additionally, they support and provide attachment points for facial muscles, allowing for facial expressions and movements.Rate this question:

What four bones form the sinuses?
- A.
Frontal
- B.
Sphenoid
- C.
Ethmoid
- D.
Maxilla
- E.
Mandible
- F.
Temporal
- G.
Vomer
Correct Answer(s)
A. Frontal
B. SpHenoid
C. Ethmoid
D. MaxillaExplanation
The sinuses are air-filled spaces within the bones of the skull. The four bones that form the sinuses are the frontal bone, sphenoid bone, ethmoid bone, and maxilla bone. These bones have hollow spaces that are lined with mucous membranes and connected to the nasal cavity. The sinuses serve various functions, including producing mucus, reducing the weight of the skull, and resonating the voice.Rate this question:

What three terms form the cranial fossa?
- A.
Anterior
- B.
Medial
- C.
Posterior
- D.
Distal
- E.
Middle
Correct Answer(s)
A. Anterior
B. Medial
C. PosteriorExplanation
The cranial fossa is the space within the skull where the brain sits. It is divided into three parts: the anterior cranial fossa, the middle cranial fossa, and the posterior cranial fossa. The terms "anterior," "medial," and "posterior" refer to the different regions of the cranial fossa.Rate this question:

What two bones form the nasal septum?
- A.
Vomer
- B.
Perpendicular plate of ethmoid
- C.
Ethmoid
- D.
Sphenoid
Correct Answer(s)
A. Vomer
B. Perpendicular plate of ethmoidExplanation
The nasal septum is formed by two bones, the vomer and the perpendicular plate of the ethmoid. The vomer is a thin, flat bone that runs vertically in the midline of the nasal cavity, separating it into two halves. The perpendicular plate of the ethmoid is a thin, bony structure that extends downward from the ethmoid bone, contributing to the formation of the nasal septum. Together, these two bones provide support and structure to the nasal cavity, helping to divide it into two separate passages.Rate this question:

What three bones form the nasal conchae?
- A.
Maxilla
- B.
Frontal
- C.
Ethmoid
- D.
Mandible
- E.
Inferior nasal conchae
Correct Answer(s)
A. Maxilla
C. Ethmoid
E. Inferior nasal conchaeExplanation
The nasal conchae are formed by three bones: the maxilla, ethmoid, and inferior nasal conchae. The maxilla is a facial bone that forms the upper jaw and contains the upper teeth. The ethmoid bone is located between the eyes and forms part of the nasal cavity. The inferior nasal conchae are small, scroll-like bones located on the lateral walls of the nasal cavity. Together, these three bones help to increase the surface area of the nasal cavity, allowing for better filtration, humidification, and warming of the inhaled air.Rate this question:

Why is the hyoid bone unique?
- A.
Only bone that sits by itself
- B.
Articulates with all bones
- C.
Doesn't articulate with any other bones
- D.
Abnormal looking to the other bones
Correct Answer
C. Doesn't articulate with any other bonesExplanation
The hyoid bone is unique because it does not articulate with any other bones in the body. Unlike other bones that are connected to each other through joints, the hyoid bone is a floating bone that sits by itself in the neck. Its lack of articulation with other bones allows it to have greater mobility and flexibility, which is important for its role in supporting the tongue and facilitating swallowing and speech.Rate this question:
