Description

Examine the structure of a scalp laceration limited to superficial layers without aponeurosis involvement. The model demonstrates how the skin and subcutaneous tissues are disrupted while the galea aponeurotica remains intact, reducing the risk of gaping wounds or severe bleeding. Learners can analyze wound edges, tissue continuity, and the importance of scalp layer anatomy in trauma evaluation. This model is particularly useful for appreciating why depth assessment is crucial in head injury examinations.
