Skull Bones

The mandible is the lower jaw bone, while the maxilla is the upper jaw bone. The zygomatic bone is commonly known as the cheekbone, and the temporal bone is located on the sides and base of the skull.

The coronal suture is the suture located between the parietal bones and the frontal bone in the human skull. It runs from side to side and separates the frontal bone from the two parietal bones. The sagittal suture connects the two parietal bones to each other along the top of the skull. The lambdoid suture connects the parietal bones to the occipital bone at the back of the skull. The squamous suture connects the parietal bones to the temporal bones on the sides of the skull.

The frontal bone is located at the front of the skull and forms the forehead, while the temporal bone is located at the sides of the skull, the mandible is the jawbone, and the scapula is the shoulder blade.

The mastoid process is a bony protrusion located behind the ear that serves as an attachment site for neck muscles. The temporal bone is adjacent to the mastoid process, while the zygomatic arch is a different bony structure in the face. The frontal sinus is a cavity within the frontal bone of the skull.

The mental foramen is a normal opening in the bone on the mandible, specifically for the passage of the mental nerve and blood vessels. Options like Optic Foramen, Foramen Magnum, and Infraorbital Foramen are incorrect because they are openings in different locations in the skull with different functions.

The occipital bone is a cranial bone located at the back of the head, forming the base of the skull. It is connected to the parietal and temporal bones.

The parietal bone is a paired bone forming the top and sides of the cranium. The frontal bone forms the forehead, the occipital bone forms the back and base of the skull, and the temporal bone forms the sides and base of the cranium.

The correct term for the horizontal portion of the mandible bone is Ramus of Mandible. The Mental Foramen, Coronoid Process, and Condylar Process are different anatomical structures in the mandible bone.

The sphenoid bone is a butterfly-shaped bone located at the base of the skull and is often referred to as the 'keystone' because it articulates with many other bones in the skull.

The correct answer is the Squamosal Suture. The Lambdoid Suture separates the occipital bone from the parietal bones, the Coronal Suture separates the frontal bone from the parietal bones, and the Sagittal Suture separates the two parietal bones from each other.

The temporal bone is a crucial bone located in the skull that houses the structures of the inner ear, including the cochlea and semicircular canals. This bone plays a vital role in auditory processing and balance.

The zygomatic bone, commonly referred to as the cheekbone, is a facial bone that forms the prominence of the cheek.

The correct answer is the condyle of the mandible, which is an important bony feature that allows for the movement of the jaw during speech and chewing. The tuberosity of the maxilla, mental foramen, and zygomatic arch are all anatomical landmarks, but they do not specifically refer to the rounded projection at the end of the lower jaw bone.

The coronoid process is a bony projection on the front of the mandible that serves as an attachment site for muscles, such as the temporalis muscle. The mandibular foramen is a hole on the inside of the mandible. The mental protuberance is the bony chin area, and the mandibular condyle is the rounded end of the mandible that articulates with the skull.

The lacrimal bone is a small and fragile bone located in the middle of the eye socket. It does not form a part of the frontal, temporal, or sphenoid bones, which are located in different regions of the skull.

The maxilla is the bone that forms the upper jaw and holds the upper teeth in place, while the mandible is the bone that forms the lower jaw. The frontal bone forms the forehead region, and the cranium is the skull structure that protects the brain.

The stapes, found in the middle ear, is the smallest bone in the human body, measuring about 3mm in length.

The occipitomastoid suture is located between the occipital bone and the mastoid part of the temporal bone. This suture helps in connecting these two bones in the skull structure. The incorrect answers are different sutures that are found in the human skull, but do not specifically connect the occipital bone to the temporal bone.

The styloid process is a small, pointed piece of bone located near the wrist. It serves as an attachment point for ligaments and muscles. The xiphoid process is a small, cartilaginous process at the lower end of the sternum. The malleolus refers to the bony protuberance on either side of the ankles. The olecranon is the pointed bony prominence at the back of the elbow.

The correct term for the bone in the skull that extends from the cheekbone to the ear is known as the 'Zygomatic Arch'. The zygomatic arch plays a role in connecting the cheekbone to the skull structure.
