What is a plexus?
"plexus" is an integral part of the nervous system where the nerves in small groups are connected. These nerve clusters combine the peripheral and central nervous system, allowing electrical signals to travel from the brain and spinal cord to the rest of the body. Without these connecting bundles, the brain would not be able to communicate with the rest of the body. Nerves are the strands of the fibers that pass through the body and provide a system where any information that the brain receives can be mediated by the rest of the body. Plexus is an area where several nerves are connected before expanding to a particular area they innervate or add. In the body there are four main nerve formations for peripheral nerves located in the neck, arms, lower and sacral areas and one for the central nervous system or CNS.
In the central nervous system or in the brain and spinal cord, the plexus is the only group of nerves. In this area, key blood vessels and specialized chambers are also present. This nerve bundle differs from peripheral nervous plexus, PRIt is where cerebrospinal fluid is formed. The cerebrospinal fluid, also known as CSF, is a protective water encirclement of the brain and spinal cord, helping to prevent injuries and foreign attackers such as bacteria.
Peripheral nervous system, or PNS, refers to all nerves that branch into the rest of the body from the central nervous system. Each peripheral nervous plexus has its own set of nerves that travel to specific areas of the body. Because every nerve in these groups receives its own message from the brain and spinal cord, several signals can be communicated to the same area that is translated into accurate movement and feeling.
Plexus placed in the neck area adds information signals to the head and neck area. Brachial the other side Lexus is located in the pit. This nerve collection is responsible for communicating with the area of the arm and shoulders. A group of nerves in the lower back of the back withHe calls the lumbar plexus. The lumbar plexus is a communication system for the rear, hips and the upper part of the thigh front.
The fourth main group of nerves is located in the sacral region. In addition to the pelvis supply, it is also a source of nerves for the back of the thigh and the rest of the foot. Sakral plexus is also provided.
