What is the nervous control system?

What is the nervous control system?

Your nervous system is your body’s command center. Originating from your brain, it controls your movements, thoughts and automatic responses to the world around you. It also controls other body systems and processes, such as digestion, breathing and sexual development (puberty).

Do arthropods have complex nervous systems?

The other complex compartmentalized nervous system is found in arthropods. The arthropodan brain consists of three main regions: the protocerebrum, deutocerebrum, and tritocerebrum.

What is the main function of the nervous system of insects?

An insect’s nervous system is a network of specialized cells (called neurons) that serve as an “information highway” within the body. These cells generate electrical impulses (action potientials) that travel as waves of depolarization along the cell’s membrane.

What is the main control of the nervous system?

the brain
The central nervous system includes the spinal cord and the brain. The brain is the body’s main control center. The main function of the CNS is the integration and processing of sensory information.

What type of nervous system do Mollusca have?

The mollusc nervous system is referred to as a tetraneural nervous system, because there are four main neural strands: Two pairs of connectives link the cerebral ganglia to the pedal ganglia on the ventral side. another to the visceral ganglia and parietal ganglia passing the pleural ganglia on the dorsal side.

Do arthropods have neurons?

In arthropods, each segmental ganglion is formed by a small number of cells, where local neurons play an important role. In many systems, these neurons have been identified physiologically and morphologically. They are mostly unique in each hemiganglion, but are repeated in the CNS segments of a given species.

What are the parts of insects nervous system?

The insect nervous system is divided into three portions: the central, the visceral, and the peripheral sensory nervous systems.

What are the 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 kind of nervous system does an arthropod have?

The arthropod’s nervous system consists of the dorsal and ventral brain, a ganglionated longitudinal nerve cord (the first pair) from which the posterior nerve originates in each phase. The system is alike to that of the annelid caterpillar from which arthropods may have originated.

What kind of nervous system does a grasshopper have?

In arthropods such as the grasshopper, the brain is divided into specialized areas, including the protocerebrum (controlling vision) and the deutocerebrum (processing antenna signals). The stomatogastric system regulates digestion.

What are the three regions of the arthropodan brain?

The arthropodan brain consists of three main regions: the protocerebrum, deutocerebrum, and tritocerebrum. The anterior protocerebrum, which receives the nerves of the eyes and other organs, contains centres, or neuropils, such as the optic centres and bodies known as corpora pedunculata.

Where are nerve endings located in the arthropod?

The sensory nerve endings are lodged in cuticular hairs (setae), peglike projections, cones, pits, or slits, which may occur in large numbers on antennae, mouthparts, joints, and leg tips. Changes in the tension of the surrounding cuticle stimulate the nerve endings.
