What are the organization of the nervous system?
The nervous system as a whole is divided into two subdivisions: the central nervous system (CNS) and the peripheral nervous system (PNS).
Does shrimp have nervous system?
It’s common knowledge that vertebrates like humans have a complex nervous system that reacts to stimuli, but much less is known about invertebrates like shrimp and insects. While it’s somewhat different from that of vertebrates, shrimp do have a central nervous system comprised of four main parts.
What are the functional organization of the nervous system?
The CNS is comprised of the brain, cerebellum and spinal cord. Remaining neurons, and associated cells, distributed throughout the body form the PNS. The nervous system has three broad functions: sensory input, information processing, and motor output.
What is central nervous system organization?
The central nervous system (CNS) consists of the brain and spinal cord. The peripheral nervous system (PNS) consists of nerves outside the CNS.

Why are lobsters boiled alive?
Lobsters and other shellfish have harmful bacteria naturally present in their flesh. Once the lobster is dead, these bacteria can rapidly multiply and release toxins that may not be destroyed by cooking. You therefore minimise the chance of food poisoning by cooking the lobster alive.
What seafood doesn’t have a nervous system?
“For me, a vegan diet is fundamentally about compassion,” he explains, “and, as current research confirms, oysters are non-sentient beings with no brain or advanced central nervous system, so they’re unable to feel pain.
What are the two primary divisions of the nervous system?
The nervous system has two main parts:
- The central nervous system is made up of the brain and spinal cord.
- The peripheral nervous system is made up of nerves that branch off from the spinal cord and extend to all parts of the body.
What is the main function of the central nervous system?
The central nervous system (CNS) controls most functions of the body and mind. It consists of two parts: the brain and the spinal cord. The brain is the center of our thoughts, the interpreter of our external environment, and the origin of control over body movement.
What is the primary function of the myelin sheath?
Myelin is an insulating layer, or sheath that forms around nerves, including those in the brain and spinal cord. It is made up of protein and fatty substances. This myelin sheath allows electrical impulses to transmit quickly and efficiently along the nerve cells. If myelin is damaged, these impulses slow down.
Where is the nerve cord located in a shrimp?
Nerve Cord. The ventral nerve cord, as opposed to the dorsal cord that defines vertebrates, is part of the nervous system of some phyla of the invertebrates, including shrimp. It runs down the ventral, or belly, side and is attached to the ganglia along the dorsal (back) side.
What is the function of the brain in shrimp?
It contains billions of nerve cells that are connected by synapses to other cells and can send a train of signal pulses throughout the body. Its function is to exert control over the organs of the body. Most nervous impulses in shrimp must run through the brain before being processed.

What kind of body does a shrimp have?
Shrimp are classified in subphylum Crustacea, along with lobsters and crabs, and have an extensive fossil record dating back as far as the Cambrian period, 543 million years ago. Most crustaceans today are free-living aquatic animals with a segmented body, a chitinous hard exoskeleton, and paired, jointed limbs.
