Definition: Antebrachial (bilateral) nerve refers to the two main nerves that connect the brainstem to spinal cord. The antineuronal cells in these neurons form a structure called 'precentral nucleus'. This nucleus plays a crucial role in coordination between the central and peripheral nervous systems, including movement and sensation. In more detail: - Antebrachial (bilateral) nerve is a common name for two main nerves: the anterior cingulate, which innervates the frontal lobe, and the anterior insular, which innervates the temporal lobe. It also includes the midbrain. - The antineuronal cells in these neurons form a structure called precentral nucleus. The precentral nucleus is an important part of brainstem coordination, including movement, sensation, and communication with the spinal cord, making it vital for overall nervous system function. Antebrachial nerves are located on both sides of the brainstem, connecting the cerebellum to the medulla oblongata.
