ANGULAR NERVE Meaning and
Definition
-
Angular nerve refers to one of the sensory branches arising from the facial nerve, specifically from wherin the buccal branches interact with the upper division of the auriculotemporal nerve. Also referred to as the nervus angularis, it is connected to the zygomaticotemporal nerve and contributes to the innervation of the skin on the lower eyelid by providing sensory fibers. Originating within the mandibular region, the angular nerve courses through the tissues located beneath the muscles of facial expression. It travels upwards on the face, entering the region of the eye, and transmits sensations from the adjacent skin.
The angular nerve plays a significant role in the sensory innervation of the face, contributing to facial proprioception as well as tactile and pain sensation perception. Due to its connection with the facial nerve, any damage or dysfunction to the angular nerve can lead to disturbances in facial sensation, resulting in impaired touch perception and altered pain response. Pathologies affecting the angular nerve can include trauma, infections, inflammatory conditions, or neoplastic processes. Further examination and comprehension of the angular nerve are integral to understanding facial neuroanatomy and the impact of facial nerve disorders.
