ansiktsregion

Ansiktsregion is a term used in anatomy and medicine to refer to the facial region of the human head. This area encompasses all the external structures of the face, from the hairline down to the chin and including the ears. It is a complex region characterized by a rich network of muscles, nerves, blood vessels, and sensory organs.

The primary structures within the ansiktsregion include the forehead, eyebrows, eyes with their eyelids and lacrimal apparatus, the nose and its associated sinuses, the cheeks, the mouth with its lips, tongue, and teeth, and the chin. The skin of the face is generally thinner and more sensitive than elsewhere on the body and plays a crucial role in facial expression, communication, and protection.

Innervation of the ansiktsregion is primarily provided by branches of the trigeminal nerve (cranial nerve V), which controls sensation, and the facial nerve (cranial nerve VII), which controls the muscles of facial expression. The vascular supply comes from branches of the external carotid artery. The ansiktsregion is also home to several important sensory organs, including the eyes for vision, the nose for smell, and the mouth for taste and touch. Due to its prominence and complex structures, the ansiktsregion is a frequent site of both congenital anomalies and acquired conditions, requiring detailed anatomical understanding for diagnosis and treatment in medical practice.
