Inferior Hypogastric Plexus
No, the dorsal ramus does not form a plexus. It supplies nerves to the skin and muscles of the back in a segmental pattern without intermingling as in a plexus, which is a network of nerves where fibers from different spinal nerves combine and then redistribute.
The brachial plexus contains fibers from the ventral rami of the cervical spinal nerves (C5-C8) and the first thoracic spinal nerve (T1). These fibers combine to form the nerves that innervate the upper limb.
Plexus are formed in the body to help distribute nerves to various parts of the body and facilitate communication between the brain and different regions. They are organized networks of nerves that help coordinate movement, sensation, and other functions in the body by merging and diverging nerve fibers.
A bundle of nerves refers to a group of nerve fibers that are bundled together within the nervous system. These nerves transmit electrical signals between the brain and the rest of the body, allowing for communication and coordination of bodily functions.
The submucosal plexus (Meissner's plexus) is a network of nerve fibers found in the submucosa of the gastrointestinal tract that helps regulate glandular secretion and local blood flow. The myenteric plexus (Auerbach's plexus) is located between the circular and longitudinal muscle layers of the gastrointestinal tract and is responsible for controlling gastrointestinal motility. Both plexuses are part of the enteric nervous system, often referred to as the "second brain" of the body.

An analysis of nerves.
The ventral rami of spinal nerves C5 to T1 contribute fibers to the brachial plexus. This plexus is responsible for innervating the muscles and skin of the shoulder, arm, and parts of the hand. It plays a crucial role in motor and sensory functions of the upper limb.
The bladder receives motor innervation from both sympathetic fibers, most of which arise from the hypogastric plexuses and nerves, and parasympathetic fibers, which come from the pelvic splanchnic nerves and the inferior hypogastric plexus. Ahmed Urbizo
The cervical spinal nerves form the cervical plexus, the brachial spinal nerves form the brachial plexus, the lumbar and sacral spinal nerves form the lumbosacral plexus, and the sacral spinal nerves form the sacral plexus.
The brachial plexus is formed by the spinal nerves C5-T1, while the lumbosacral plexus is formed by the spinal nerves L1-S4. These plexuses are networks of nerves that supply motor and sensory innervation to the upper and lower limbs, respectively.

Cervical: C1 - C5Innervates muscles of neck and extend into thoracic cavity, where they control diaphragmatic muscles. Major nerve: Phrenic...which provides entire nerve supply to diaphragm.Brachial: C5-T1Innervates pectoral girdle and upper limbs. Major nerves: Radial nerve, median nerve, ulnar nerve.Lumbar: T12 - L4Innervates pelvic girdle and lower limbs. Major nerves: Genitofemoral nerve, lateral femoral cutaneous nerve, and femoral nerve.Sacral: L4-S5Innervates pelvic girdle and lower limbs. Major nerves: Sciatic nerve (which branches into tibial and fibular nerves) and pudendal nerve.
