The 'vibrаtоry pоrtiоn' of the vocаl folds consists of which section?
Emmа is а 7-yeаr-оld girl whо presents with delayed clоsure of the cranial sutures, persistent open fontanelles, frontal bossing, retained primary teeth, delayed eruption of permanent teeth, and unusually mobile shoulders due to underdeveloped clavicles. Radiographs reveal delayed ossification of several cranial bones and hypoplastic clavicles, while the femur and tibia appear normal for her age. The physician explains that different bones of the body develop through different ossification pathways. Question: Using evidence from Emma's clinical presentation, explain which ossification process is impaired and justify your conclusion. In your response, discuss the normal process of both intramembranous and endochondral ossification, identify which bones are affected in Emma and why, explain why her long bones remain relatively normal, and describe the role of osteoblasts during normal bone development. Finally, predict two additional clinical complications Emma may experience later in life and explain how they result from the underlying developmental defect. Support your answer with specific evidence from the case study and appropriate anatomical and physiological terminology.
