Katena32 [7]

Answer:

only sympathetic fibers can regenerate accurately

Explanation:

Neuroregeneration is a complex biological process associated with the regrowth and/or repair of nervous tissues. This process depends on the type of nerve tissue and how seriously the nerve was injured. The autonomic nervous system, also known as the autonomic nervous system (ANS), is part of the peripheral nervous system (PNS) that is responsible for regulating involuntary physiological processes. The PNS contains two basic divisions: sympathetic and parasympathetic. The sympathetic fibers innervate tissues in nearly all the organ systems and they are responsible for regulating homeostatic processes (e.g., heart rate). The sympathetic nervous system is formed by nerves from the thoracic and lumbar segments of the spinal cord. These autonomic nerves can regenerate after injury in order to reinnervate target tissues (e.g., after chronic cardiac ischemia).
