Difference between Nerve net and Nervous system

Nerve net vs. Nervous system

A nerve net consists of interconnected neurons lacking a brain or any form of cephalization. The nervous system is the part of an animal that coordinates its actions by transmitting signals to and from different parts of its body.

Similarities between Nerve net and Nervous system

Nerve net and Nervous system have 27 things in common (in Unionpedia): Animal, Bilateria, Brain, Central nervous system, Cnidaria, Ctenophora, Echinoderm, Ectoderm, Endoderm, Ganglion, Gastrulation, Homology (biology), Hormone, Hydra (genus), Myelin, Neuroblast, Neurogenesis, Neuron, Phylum, Radiata, Sea anemone, Sensory neuron, Sponge, Symmetry in biology, Synapse, Ventral nerve cord, Vertebrate.

Animal

Animals are multicellular eukaryotic organisms that form the biological kingdom Animalia.

Bilateria

The Bilateria or bilaterians, or triploblasts, are animals with bilateral symmetry, i.e., they have a head (anterior) and a tail (posterior) as well as a back (dorsal) and a belly (ventral); therefore they also have a left side and a right side.

Brain

The brain is an organ that serves as the center of the nervous system in all vertebrate and most invertebrate animals.

Central nervous system

The central nervous system (CNS) is the part of the nervous system consisting of the brain and spinal cord.

Cnidaria

Cnidaria is a phylum containing over 10,000 species of animals found exclusively in aquatic (freshwater and marine) environments: they are predominantly marine species.

Ctenophora

Ctenophora (singular ctenophore, or; from the Greek κτείς kteis 'comb' and φέρω pherō 'to carry'; commonly known as comb jellies) is a phylum of invertebrate animals that live in marine waters worldwide.

Echinoderm

Echinoderm is the common name given to any member of the phylum Echinodermata (from Ancient Greek, ἐχῖνος, echinos – "hedgehog" and δέρμα, derma – "skin") of marine animals.

Ganglion

A ganglion is a nerve cell cluster or a group of nerve cell bodies located in the autonomic nervous system and sensory system.

Gastrulation

Gastrulation is a phase early in the embryonic development of most animals, during which the single-layered blastula is reorganized into a multilayered structure known as the gastrula.

Homology (biology)

In biology, homology is the existence of shared ancestry between a pair of structures, or genes, in different taxa.

Hormone

A hormone (from the Greek participle “ὁρμῶ”, "to set in motion, urge on") is any member of a class of signaling molecules produced by glands in multicellular organisms that are transported by the circulatory system to target distant organs to regulate physiology and behaviour.

Hydra (genus)

Hydra is a genus of small, fresh-water organisms of the phylum Cnidaria and class Hydrozoa.

Myelin

Myelin is a lipid-rich substance that surrounds the axon of some nerve cells, forming an electrically insulating layer.

Neuroblast

A neuroblast or primitive nerve cell is a dividing cell that will develop into a neuron often after a migration phase.

Neurogenesis

Neurogenesis is the process by which nervous system cells, known as neurons, are produced by neural stem cells (NSC)s, and it occurs in all species of animals except the porifera (sponges) and placozoans.

Neuron

A neuron, also known as a neurone (British spelling) and nerve cell, is an electrically excitable cell that receives, processes, and transmits information through electrical and chemical signals.

Phylum

In biology, a phylum (plural: phyla) is a level of classification or taxonomic rank below Kingdom and above Class.

Radiata

Radiata or Radiates is a historical taxonomic rank that was used to classify animals with radially symmetric body plans, and is no longer accepted.

Sensory neuron

Sensory neurons also known as afferent neurons are neurons that convert a specific type of stimulus, via their receptors, into action potentials or graded potentials.

Sponge

Sponges, the members of the phylum Porifera (meaning "pore bearer"), are a basal Metazoa clade as sister of the Diploblasts.

Synapse

In the nervous system, a synapse is a structure that permits a neuron (or nerve cell) to pass an electrical or chemical signal to another neuron or to the target efferent cell.

Ventral nerve cord

The ventral nerve cord (VNC) makes up a part of the central nervous system of some phyla of the bilaterians, particularly within the nematodes, annelids and the arthropods.
