Crouzon syndrome

a condition in which a wide skull with a protrusion near the anterior fontanel (on top of the head, at the front) is associated with a beaked nose and ocular abnormalities (see craniosynostosis syndrome). The latter may include atrophy, divergent strabismus, and blindness. Neurological disorders may result from intracranial pressure, and intellectual disability may occur in some cases. Also called craniofacial dysostosis. See also Apert syndrome. [described in 1912 by Octave Crouzon (1874–1938), French neurologist]

dominance–subordination

a form of social relationship within groups with a leader or dominant member who has priority of access to resources over other, subordinate members of the community. Among nonhuman animals, dominance–subordination relationships are highly organized in troops of baboons, in which dominant males have more access to food resources and mates than do subordinate males and all males often appear to have dominance over females. In hyena groups, the relationship is reversed, with males subordinate to females.
