- C.
Palatine
- D.
Mandible
Correct Answer
B. LacrimalExplanation
The lacrimal bone is the smallest bone of the skull. It is located in the medial wall of the orbit and forms a part of the eye socket. Its main function is to house the lacrimal sac, which collects tears and drains them into the nasal cavity. The lacrimal bone is thin and delicate, making it the smallest bone in the skull.Rate this question:

13. The suture between frontal and temporal bones is:
- A.
Coronal suture
- B.
Sagittal suture
- C.
Lambdoidal suture
- D.
Squamosal suture
Correct Answer
A. Coronal sutureExplanation
The suture between the frontal and temporal bones is called the coronal suture. This suture runs horizontally across the skull and joins the frontal bone with the two parietal bones. It is named "coronal" because it is located in the coronal plane, which is a vertical plane that divides the body into front and back portions. The other options, sagittal suture, lambdoidal suture, and squamosal suture, are all different sutures located in different areas of the skull.Rate this question:

Squamosal suture
Correct Answer
B. Sagittal sutureExplanation
The suture between the parietal bones is known as the sagittal suture. Sutures are fibrous joints that connect the bones of the skull. The sagittal suture specifically runs along the midline of the skull, separating the two parietal bones. It is a dense, immovable joint that provides stability and protection to the brain.Rate this question:

Squamosal suture
Correct Answer
D. Squamosal sutureExplanation
The suture between the temporal and parietal bones is called the squamosal suture. This suture is located on the side of the skull, where the squamous portion of the temporal bone articulates with the parietal bone. It has a jagged, irregular shape resembling scales, which is why it is called the squamosal suture.Rate this question:

16. The suture between parietal and occipital bones is:
- A.
Coronal suture
- B.
Lambdoidal suture
- C.
Squamosal suture
Correct Answer
B. Lambdoidal sutureExplanation
The suture between the parietal and occipital bones is called the lambdoidal suture. This suture is located at the back of the skull and is named after its resemblance to the Greek letter lambda (Λ). It is a dense, fibrous joint that helps to connect and stabilize the parietal and occipital bones, forming the posterior part of the skull. The lambdoidal suture is important for the overall structure and strength of the skull, as well as for protecting the brain.Rate this question:

17. Infra-orbital foramen is on:
- A.
Zygoma
- B.
Maxilla
- C.
Palatine bone
- D.
Nasal Bone
Correct Answer
B. MaxillaExplanation
The infra-orbital foramen is located on the maxilla bone. The maxilla is a facial bone that forms the upper jaw and the central part of the face. It contains various foramina, including the infra-orbital foramen, which is located below the orbit (eye socket) and transmits the infra-orbital nerve and blood vessels. The zygoma is a cheekbone, the palatine bone forms the roof of the mouth, and the nasal bone forms the bridge of the nose. However, none of these bones contain the infra-orbital foramen.Rate this question:

- D.
2 foramens, Mental and Incisive foramens
Correct Answer
C. 2 foramens, Mandibular and Mental foramensExplanation
The correct answer is 2 foramens, Mandibular and Mental foramens. The mandible, or lower jawbone, has two main foramens, which are openings or holes in the bone. The mandibular foramen is located on the inner surface of the mandible near the back, and it allows for the passage of the inferior alveolar nerve and blood vessels. The mental foramen is located on the outer surface of the mandible near the front, and it allows for the passage of the mental nerve and blood vessels.Rate this question:

- A.
Pia Mater
- B.
Dura Mater
- C.
Arachnoid Mater
- D.
All of them
Correct Answer
D. All of themExplanation
The correct answer is "All of them." The meninges is a protective membrane that surrounds the brain and spinal cord. It is composed of three layers: the pia mater, dura mater, and arachnoid mater. Each of these layers plays a role in providing support and protection to the central nervous system. Therefore, all three layers contribute to the formation of the meninges.Rate this question:

- B.
Below Arachnoid Mater
- C.
Between Dura and Arachnoid Maters
- D.
Between Arachnoid and Pia Maters
Correct Answer
D. Between Arachnoid and Pia MatersExplanation
The subarachnoid space is located between the arachnoid and pia maters. It is filled with cerebrospinal fluid (CSF) and contains blood vessels that supply nutrients to the brain and spinal cord. This space plays a crucial role in protecting the central nervous system from injury and providing a cushioning effect for the brain and spinal cord.Rate this question:

- A.
Dura Mater
- B.
Subarachnoid space
- C.
Extradural Space
- D.
Pia Mater
Correct Answer
B. Subarachnoid spaceExplanation
The cerebrospinal fluid (CSF) is found in the subarachnoid space. This space is located between the arachnoid mater and the pia mater, which are two of the three layers of the meninges that protect the brain and spinal cord. The CSF acts as a cushioning and protective fluid, providing support and nourishment to the central nervous system. It also helps to remove waste products and regulate the chemical environment of the brain and spinal cord.Rate this question:

Subdural and Subarachnoid Spaces
- C.
Potential and Subarachnoid Spaces
- D.
Epidural Space and Subdural, Subarachnoid Spaces
Correct Answer
D. Epidural Space and Subdural, Subarachnoid SpacesExplanation
The correct answer is Epidural Space and Subdural, Subarachnoid Spaces. The meninges are the protective membranes that surround the brain and spinal cord. The epidural space is the space between the skull or vertebral column and the dura mater, which is the outermost layer of the meninges. The subdural space is the space between the dura mater and the arachnoid mater, which is the middle layer of the meninges. The subarachnoid space is the space between the arachnoid mater and the pia mater, which is the innermost layer of the meninges. Therefore, the meninges are present in both the epidural space and the subdural and subarachnoid spaces.Rate this question:

- B.
Anterior meningeal artery
- C.
C. Posterior meningeal artery
- D.
Internal Carotid artery
Correct Answer
A. Middle meningeal arteryExplanation
The middle meningeal artery supplies the cranial dura mater. The dura mater is the outermost layer of the meninges, which are the protective coverings of the brain and spinal cord. The middle meningeal artery is a branch of the maxillary artery, which is itself a branch of the external carotid artery. It enters the cranial cavity through the foramen spinosum and supplies blood to the dura mater of the middle cranial fossa.Rate this question:

Correct Answer
A. Dura materExplanation
The dural venous sinuses are located within the dura mater, which is the outermost layer of the meninges. The dura mater is a tough, fibrous membrane that surrounds and protects the brain and spinal cord. It contains several spaces and channels, including the dural venous sinuses, which are responsible for draining blood from the brain and returning it to the systemic circulation. The dural venous sinuses play a crucial role in maintaining the proper circulation of cerebrospinal fluid and removing waste products from the brain.Rate this question:

- C.
Aponeurosis
- D.
Loose Connective Tissue
- E.
Pericranium
Correct Answer
C. AponeurosisExplanation
The frontalis and occipitalis muscles are connected by aponeurosis. Aponeurosis is a sheet-like tendon that connects muscles to bones or other muscles. In this case, it connects the frontalis muscle, which is located in the forehead, to the occipitalis muscle, which is located in the back of the head. This connection allows for coordinated movement and function between the two muscles.Rate this question:
