efferent nerve
Quick Summary
Efferent nerve fibers are a crucial part of the peripheral nervous system, carrying motor information away from the central nervous system to target organs like skeletal muscles or autonomic ganglia. These fibers originate from nerve cell bodies within the brain or spinal cord and extend to their destinations.12
There are two main types of efferent fibers:
* General somatic efferent fibers: These innervate voluntary skeletal muscles.12
* General visceral efferent fibers: These are part of the autonomic nervous system and control involuntary muscles (like cardiac and smooth muscle) and glands. These fibers form a pathway involving preganglionic and postganglionic neurons, with the latter extending to the target organs.12
