What bones does the occipital bone articulate with?

The occipital bone articulates with the temporal bones, parietal bones, and sphenoid bone.

What type of bone is occipital bone?

flat bone
The occipital bone is the most posterior cranial bone and the main bone of the occiput. It is considered a flat bone, like all other cranial bones, meaning that its primary function is either for protection or to provide a broad surface for muscle attachment.

Is Fossa made of bone?

The anterior cranial fossa is formed by the orbital part of the frontal bone, the cribriform plate and crista galli of the ethmoid bone, and the lesser wings and anterior part of the body (jugum sphenoidale and prechiasmatic sulcus) of the sphenoid bone (Standing, 2015).

What bones have a fossa?

In the Skull:

• Cranial fossa. Anterior cranial fossa. Middle cranial fossa. Interpeduncular fossa.
• Hypophyseal fossa.
• Temporal bone fossa. Mandibular fossa. Jugular fossa.
• Infratemporal fossa.
• Pterygopalatine fossa.
• Pterygoid fossa.
• Lacrimal fossa. Fossa for lacrimal gland. Fossa for lacrimal sac.
• Mandibular fossa.

What are the 4 divisions of occipital bone?

Because of that, the occipital bone is described in terms of separate parts which are: the basilar part, squamous part, lateral parts (placed laterally to the foramen magnum). This article will deal with detailed anatomy of the occipital bone.

Which bones are divided by the sagittal suture?

Sagittal suture, runs longitudinally across the skull from the occipital to the frontal bone and separates the parietal bones from one another. Lambdoid suture, is an inverted “V” in shape and separates the occipital bone from the parietals.

Where is the sagittal suture?

skull
The sagittal suture, also known as the interparietal suture and the sutura interparietalis, is a dense, fibrous connective tissue joint between the two parietal bones of the skull. The term is derived from the Latin word sagitta, meaning arrow.

What is back of skull called?

occipital bone
The occipital bone is a bone that covers the back of your head; an area called the occiput. The occipital bone is the only bone in your head that connects with your cervical spine (neck).

What structures are in the infratemporal fossa?

Infratemporal Fossa. It is not fully enclosed by bone. The infratemporal fossa serves as the passageway for many neurovascular structures. In addition to this, it contains superficial muscles like the inferior portion of the temporalis muscle, the lateral pterygoid muscle and the medial pterygoid muscle.

What is the fossa of the temporal bone?

The fossa is closely associated with both the pterygopalatine fossa, via the pterygomaxillary fissure, and also communicates with the temporal fossa, which lies superiorly (figure 1.0). The boundaries of this complex structure consists of both bone and muscle: Lateral – condylar process and ramus of the mandible bone.

What arteries are in the infratemporal fossa?

Internal maxillary branches found within the infratemporal fossa including the. middle meningeal artery. inferior alveolar artery. deep temporal artery. buccal artery.

Where is the pterygopalatine fossa located?

It is located deep to the masseter muscle and zygomatic arch (to which the masseter attaches). The fossa is closely associated with both the pterygopalatine fossa, via the pterygomaxillary fissure, and also communicates with the temporal fossa, which lies superiorly (figure 1.0).
