21. The tibial surfaces of the condyles are convex from side to side and from before backward. 22. This dislocation will push the jaw back affecting the alignment of the mandibular condyle and mastoid. 23. A growth center is located in the head of each mandibular condyle before an individual reaches maturity. 24. This growth center consists of hyaline cartilage underneath the periosteum on the articulating surface of the condyle . 25. When an individual reaches full maturity, the growth center of bone within the condyle has disappeared. 26. The occiput sloped backwards and down, and the occipital condyle was deflected in the same direction. 27. Ideally, it is aligned so that a continuation of this arc would extend through the condyles . 28. The humerus has a boss above the condyle that contacts the radius, that is hook-shaped. 29. The "'Archaeognatha "'are an condyle , where all higher insects have two. 30. Romer ( 1976 ) homologizes the capitellum in archosauromorphs with the groove separating the medial and lateral condyles .
