Yes.
No sponges lack organized multicellular organs, such as nerves and muscles.
Scientists have organized the cells that make up the nervous system into two broad groups: neurons, which are the primary signaling cells, and glia, which support neurons in various ways. The human brain contains around 100 billion neurons and, by most estimates, somewhere between 10 to 50 times as many glial cells. Bipolar ones are usually found outside the brain and interneurons are found within the brain.
sensory neurons
Sensory Neurons
Sensory neurons and neurons are connected by Interneurons.
Interneurons or association neurons.
Motor neurons and intern neurons
The neurons form the bodies nervous system.
Sensory Neurons
Afferent Neurons
Interneurons or association neurons are connector neurons that establish connections between other neurons.
