The vomer (/ ˈ v oʊ m ər /; [1] [2] Latin: vomer, lit. 'ploughshare') is one of the unpaired facial bones of the skull . It is located in the midsagittal line, and articulates with the sphenoid , the ethmoid , the left and right palatine bones, and the left and right maxillary bones.
The facial skeleton comprises the facial bones that may attach to build a portion of the skull. [1] The remainder of the skull is the neurocranium.. In human anatomy and development, the facial skeleton is sometimes called the membranous viscerocranium, which comprises the mandible and dermatocranial elements that are not part of the braincase.
The human skull is the bone structure that forms the head in the human skeleton. It supports the structures of the face and forms a cavity for the brain. Like the skulls of other vertebrates, it protects the brain from injury. [6]
The white visible part of a tooth is called the crown. The rounded upper projections of the back teeth are cusps. The hard white exterior covering of the tooth is the enamel. As the tooth tapers below the gumline, the neck is formed. Below the neck, holding the tooth into the bone, is the root of the tooth.
The bones are derived from dermal bone and are part of the dermatocranium. In comparative anatomy , the term is applied to the whole dermatocranium. [ 1 ] In general anatomy, the roofing bones may refer specifically to the bones that form above and alongside the brain and neurocranium (i.e., excluding the marginal upper jaw bones such as the ...
the membranous part, consisting of flat bones, which surround the brain; and; the cartilaginous part, or chondrocranium, which forms bones of the base of the skull. [3] In humans, the neurocranium is usually considered to include the following eight bones: 1 ethmoid bone; 1 frontal bone [5] 1 occipital bone; 2 parietal bones; 1 sphenoid bone; 2 ...
The frontal and sphenoid bones are towards the front middle of the skull and in front of the temporal bone. The ethmoid bone is the bone at the roof of the nose that separates the nasal cavity from the brain. It is a part of the dorsal cavity the cranial cavity and the spinal cord. The occipital bone is at the back of the skull.
The calvaria is the top part of the skull. It is the superior part of the neurocranium and covers the cranial cavity containing the brain. It forms the main component of the skull roof. The calvaria is made up of the superior portions of the frontal bone, occipital bone, and parietal bones. [1]
