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.
Waters' view (also known as the occipitomental view or parietoacanthial projection) is a radiographic view of the skull.It is commonly used to get a better view of the maxillary sinuses.
The x-ray can be taken with the patient in either an erect or supine position, although most usually erect. The x-ray is taken PA (postero-antero), meaning that the patient faces towards the receiver and away from the x-rays source.
Marked radiopacity is seen. (Denser than bone) Erythroblastic anemia: Hypopneumatisation (decreased pneumatisation) is common finding in sickle cell anemia and beta thalassemia. Hyperpneumatisation (increased pneumatisation ) is common finding in Acromegaly and Sturge–Weber syndrome.
The appendicular skeleton, comprising the arms and legs, including the shoulder and pelvic girdles, contains 126 bones, bringing the total for the entire skeleton to 206 bones. Infants are born with about 270 bones [ 4 ] with most of it being cartilage, but will later fuse together and decrease over time to 206 bones.
The facial bones usually form into pairs and then fuse together. As the cranium fuses, sutures are formed that resemble stitching between bone plates. In a newborn, the junction of the parietal bones with the frontal and occipital bones, form the anterior (front) and posterior (back) fontanelle , or soft spots.
Forensic reconstruction is a lengthy and time-consuming process that involves using the shape of facial bones to create a general head and face shape, as well as impressions of those bones to ...
