Also question is, what is a plexus in anatomy?
FMA. 5901. Anatomical terms of neuroanatomy. A nerve plexus is a plexus (branching network) of intersecting nerves. A nerve plexus is composed of afferent and efferent fibers that arise from the merging of the anterior rami of spinal nerves and blood vessels.
Beside above, what is plexus in biology? A plexus (from the Latin for "braid") is a branching network of vessels or nerves. The vessels may be blood vessels (veins, capillaries) or lymphatic vessels. The nerves are typically axons outside the central nervous system.
Likewise, what are the plexuses in the body?
- Cervical Plexus—Serves the Head, Neck and Shoulders.
- Brachial Plexus—Serves the Chest, Shoulders, Arms and Hands.
- Lumbar Plexus—Serves the Back, Abdomen, Groin, Thighs, Knees, and Calves.
- Sacral Plexus—Serves the Pelvis, Buttocks, Genitals, Thighs, Calves, and Feet.
