The Brain and Nervous System of Fish Being highly complex life forms fish need a brain and a nervous system to control their body's actions. The nervous system of fish, much like ours, is composed of a central co-ordinating brain, a spinal cord and many, many nerves.he Nerves :- Apart from the brain and the spinal cord the fish body is supplied with a vast network of nerves, the electric wires of the body along which messages travel.

- The nervous system is composed of the brain and spinal cord, together known as the central nervous system, and a vast array of peripheral nerves that transmit information to and from these central structures. The nervous system may be damaged by infection, injury, vascular problems, inflammation, and degeneration.

- Central nervous system depression can be dangerous because the CNS is responsible for coordinating the functions of all parts of the body; if left untreated, central nervous system depression can result in a coma or death, according to author Dr. Melissa Conrad Stoeppler. stöpplerhe central nervous system is made up of the brain and spinal cord, and it is the majority of the nervous system. The central nervous system receives sensory input from the somatic nervous system and autonomic nervous system and sends out the motor response.

THE NERVOUS SYSTEM The vertebrate nervous system is divided into a number of parts. The central nervous system includes the brain and spinal cord. The peripheral nervous system consists of all body nerves. Motor neuron pathways are of two types: somatic (skeletal) and autonomic (smooth muscle, cardiac muscle, and glands).he Peripheral Nervous System (PNS)contains only nerves and connects the brain and spinal cord (CNS) to the rest of the body. The axons and dendrites are surrounded by a white myelin sheath. Cell bodies are in the central nervous system (CNS) or ganglia.

Biological system An example of a system: The brain, the cerebellum, the spinal cord, and the nerves are the four basic components of the nervous system. These specific systems are widely studied in Human anatomy. Human systems are also present in many other animals.

The Nervous System The central nervous system is divided into a number of important parts (see Figure 4), including the spinal cord, each specialized to perform a set of specific functions. Telencephalon or cerebrum is a newer development in the evolution of the mammalian nervous system. In humans, it is about the size of a large napkin and when crumpled into the skull, it forms furrows called sulci (singular form, sulcus). The bulges between sulci are called gyri (singular form, gyrus).

- Invertebrates are those animals without a backbone (spinal column). Invertebrates include animals such as insects, worms, jellyfish, spiders-these are only a few of the many types of spineless creatures. Invertebrates have played an important role in discoveries about how the nervous system works.he nervous system of the starfish is very simple...there is no brain and there are not even any ganglia to coordinate movement. The nervous system is characterized by a nerve ring that surrounds the mouth. A radial nerve branches off of the nerve ring and extends to each arm.

Vertebrate brain A highly complex organ consisting of sensory and motor systems that constitutes part of the nervous system. Virtually all of the brain systems that are found in mammals occur in birds, reptiles, and amphibians, as well as in fishes and sharks.

Feline Nervous System As marvelous as the feline nervous system can be, there are possible disorders. The four most common neurological diseases found in many clinical practices are: (1) congenital abnormalities, (2) trauma, (3) tumors and (4) middle or inner ear infections. (1) Two congenital abnormalities are fairly prevalent in cats.

- Overview. The nervous system is organized into two parts: the central nervous system, which consists of the brain and the spinal cord, and the peripheral nervous system, which connects the central nervous system to the rest of the body.An image depicting the central nervous system can be seen below.he hindbrain is found in even the most primitive vertebrates. It is made up of the cerebellum, the pons, and the medulla. The medulla is a narrow structure nearest the spinal cord; it is the point at which many of the nerves from the left part of the body cross to the right side of the brain and vice versa.

- 1 The central nervous system is made up of the brain and spinal cord.  The peripheral nervous system is made up of the nerve fibers that branch off from the spinal cord and extend to all parts of the body, including the neck and arms, torso, legs, skeletal muscles and internal organs.

Spinal Nerves The nervous system is divided into two systems. The Central Nervous System which is the brain and the spinal cord, and the Peripheral Nervous System which is the 12 cranial nerves, 31 pairs of spinal nerves and ganglia. The Peripheral Nervous System provides communication between the brain and spinal cord and the body’s muscles, glands and sensory receptors.

Nervous system In vertebrate species it consists of two main parts, the central nervous system (CNS) and the peripheral nervous system (PNS). The CNS contains the brain and spinal cord. The PNS consists mainly of nerves, which are enclosed bundles of the long fibers or axons, that connect the CNS to every other part of the body.he size of the nervous system ranges from a few hundred cells in the simplest worms, to around 100 billion cells in humans. The central nervous system functions to send signals from one cell to others, or from one part of the body to others and to receive feedback.

Invertebrate They are radial symmetry and the other one is called as bilateral symmetry. Invertebrates have simple nervous system. The internal anatomy of the invertebrates differs from each other. Some may have respiratory, excretory and circulatory organs and in some species these organs may be absent.nimals that lack backbone are called as invertebrates. These invertebrates are seen in all places from deserts to forests and from caves to seabed and even in unbearable Polar Regions. They can also been seen in the air. And most of the invertebrates are small in their size and only few reach the impressive sizes.

Definitions &Translations The brain is an organ that serves as the center of the nervous system in all vertebrate and most invertebrate animals. Only a few invertebrates such as sponges, jellyfish, adult sea squirts and starfish do not have a brain; diffuse or localised nerve nets are present instead.he brain is the most complex organ in a vertebrate's body. In a typical human, the cerebral cortex (the largest part) is estimated to contain 15–33 billion neurons, each connected by synapses to several thousand other neurons.

Brain For information specific to the human brain, see Human brain. For other uses, see Brain (disambiguation). The brain is an organ that serves as the center of the nervous system in all vertebrate and most invertebrate animals. The brain is located in the head, usually close to the sensory organs for senses such as vision. The brain is the most complex organ in a vertebrate's body.
