What is the difference between the frog and human nervous system?
The brain and spinal cord of a human are protected by a triple layer of membranes called meninges; the meninges of the frog have only 2 layers. Human brains are more developed that those of amphibians and contain a cerebral cortex which the frog lacks. A human has 30 pairs of spinal nerves, while a frog has only 10.
Where is a spinalcord on a frog?
The spinal cord on a frog is located inside the vertebral column, running along the back of the frog. It is part of the central nervous system and is responsible for transmitting signals between the brain and the rest of the body to control movement and reflexes.
What is a frogs chromatophore?
A frog's chromatophore is a specialized cell that contains pigment granules which allow the frog to change its skin color to match its surroundings and help with camouflage. These cells are controlled by the frog's nervous system and can expand or contract to alter the color and pattern of the frog's skin.
What is a pithed frog?
A pithed frog is a frog that has had its central nervous system destroyed by the insertion of a sharp object into the base of its brain or spinal cord. This process is done to immobilize the frog while keeping its organs alive for scientific research or educational purposes.
How does the heart of a double pithed frog contract in an organized manner after the nervous system is destroyed?
The nervous system is part of the respiratory and circulatory system. It is the brain, spinal cord, and nerves. When the nervous system is destroyed the heart of a double pithed frog contracts in an organized manner. This is exemplified in other animals as well for instance in alligators because the nerves for some time after death continue to fire. The firing of nerves send electrical signals to the heart and therefore pump it.
What part of the frog's nervous system can be observed in the abdominal cavity?
Well, if you dissected it and payed attentions in class, you'd know that the part of the frog's nervous system that can be observed in its abdominal cavity AND hind legs are its arteries.
What does the nervous system consist of in a frog?
Consists of the brain, spinal cord, and nerves.

What are traits of an organism controlled by nervous system?
The organism controlled by nervous system must be vertebrate. The organisms without developed nervous system are capable only of vegetative reactions. (See the experiments of Luigi Galvani with the frog's leg.)
What organ system does the brain belong too?
The nervous system The central nervous system
Does the central nervous system consist of the somatic nervous system?
No. Nervous System is comprised of the Central Nervous System (CNS) and the Peripheral Nervous System (PNS) The PNS is comprised of the Somatic Nervous System and the Autonomic Nervous System The Autonomic Nervous System is comprised of the Sympathetic Nervous System, the Parasympathetic Nervous System and the Enteric Nervous System

What comprises the nervous system?
The Sympathetic Nervous System and the Parasympathetic Nervous System
The portion of the nervous system away from the central nervous system?
The peripheral nervous system is the portion of the nervous system away from the central nervous system. It consists of nerves that connect the central nervous system to the rest of the body, including sensory and motor neurons. The peripheral nervous system is responsible for transmitting information to and from the central nervous system.
The cranial and spinal nerves form what nervous system?
the peripheral nervous system
The somatic nervous system is a component of what nervous system?
The somatic nervous system is a component of the peripheral nervous system. This system is responsible for voluntary movements and sensory information.
