Detailed explanation-1: -Cnidarians have nerve cells that are organized in a nerve net – a diffuse network where neurons interact wherever they cross one another. There are two contrasting types of body symmetry: radial and bilateral. Nerve nets are associated with the former and central nervous systems with the latter.

Detailed explanation-2: -Introduction. Cnidarians are frequently referred to as “nerve net animals, ” even though the majority of extant species show some form of centralization of the nervous system in addition to the acknowledged organization of a nerve net in many areas of the body ( Mackie 2004; Garm et al.

Detailed explanation-3: -Cnidarians are considered “nerve net animals” even though their nervous systems include various forms of condensation and centralization. Yet, their broad, two-dimensional muscle sheets are innervated by diffuse nerve nets.

Detailed explanation-4: -The nerve net is the simplest form of a nervous system found in multicellular organisms. Unlike central nervous systems, where neurons are typically grouped together, neurons found in nerve nets are spread apart. This nervous system allows cnidarians to respond to physical contact.
