Where is frontal bone located?
forehead
The frontal bone is a shell-shaped, unpaired, flat bone of the skull located in the forehead region. The frontal bone consists of six main parts: the squamous part, nasal part, two orbital plates and two zygomatic plates.
Where is the frontal bone located quizlet?
The frontal is located at the front of the neurocranium. It articulates with the parietals, nasals, maxillae, sphenoid, ethmoid, lacrimals, and zygomatics. The frontal is one of the largest and most robust cranial bones.
What is the frontal bone part of?
human skull
The frontal bone is a bone in the human skull. The bone consists of two portions. These are the vertically oriented squamous part, and the horizontally oriented orbital part, making up the bony part of the forehead, part of the bony orbital cavity holding the eye, and part of the bony part of the nose respectively.
Where are the parietal and frontal bones located?
cranium
The parietal and temporal bones form the sides and uppermost portion of the dome of the cranium, and the frontal bone forms the forehead; the cranial floor consists of the sphenoid and ethmoid bones.
What is the function of frontal bone?
The frontal bone is one of the eight bones that together form the cranium, otherwise known as the protective case of the brain. The primary functions of the frontal bone are to protect the brain and support the structures of the head, such as the nasal passages and eyes.

What does the frontal bone connect to?
Within the cranium, the frontal bone connects with the ethmoid bone inferiorly and medially. Posteriorly and inferiorly, the frontal bone meets the sphenoidal bone. As the frontal bone ascends posteriorly and laterally, it will meet the temporal bone, then finally the parietal at the top of the skull.
What is the function of the parietal bone?
The function of the cranium, and hence the parietal bones, is to protect the underlying fragile brain. The parietal bone is slightly curved and has a quadrilateral shape. It has two surfaces, four borders and four angles. The borders articulate with the neighbouring skull bones to form various cranial sutures.
What is parietal lobe function?
The parietal lobes are responsible for processing somatosensory information from the body; this includes touch, pain, temperature, and the sense of limb position. Like the temporal lobes, the parietal lobes are also involved in integrating information from different modalities.
