It is done by distorting the normal growth of a child's skull by applying pressure. Flat shapes, elongated ones (produced by binding between two pieces of wood), rounded ones (binding in cloth), and conical ones are among those chosen or valued in various cultures. Typically, the alteration is carried out on an infant, when the skull is most ...
Only a comparatively small part of the head at term is represented by the face. The rest of the head is composed of the firm skull, which is made up of two frontal, two parietal, and two temporal bones, along with the upper portion of the occipital bone and the wings of the sphenoid. These bones are separated by membranous spaces, or sutures.
It is distinct from phrenology, the pseudoscience that tried to link personality and character to head shape, and physiognomy, which tried the same for facial features. Today, physical and forensic anthropologists use craniometry to study the evolution of human populations, determining the origin of ancient remains such as the Kennewick Man .
Beyond the face value of what males find physically attractive, secondary sexual characteristics related to body shape are factored in so adults may be able to recognize other adults from juveniles. A major part of the cosmetic world is built around capitalizing on enhancing these neonate features.
In obstetrics, a cephalic presentation or head presentation or head-first presentation is a situation at childbirth where the fetus is in a longitudinal lie and the head enters the pelvis first; the most common form of cephalic presentation is the vertex presentation, where the occiput is the leading part (the part that first enters the birth canal).

Skull in situ Human head skull from side Anatomy of a flat bone – the periosteum of the neurocranium is known as the pericranium Human skull from the front Side bones of skull. 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 ...
When the vacuum is applied to the infant's head, the tension creates a difference in pressure between the atmosphere and the infant's scalp that causes the soft tissue layers of the scalp to fill inside the suction cup. [5] [6] Subsequently, interstitial fluid and small hemorrhages build up, causing the head to swell and forming a localized edema.
A 2-D model of cortical sensory homunculus. A cortical homunculus (from Latin homunculus 'little man, miniature human' [1] [2]) is a distorted representation of the human body, based on a neurological "map" of the areas and portions of the human brain dedicated to processing motor functions, and/ or sensory functions, for different parts of the body.
