What is the best way to describe the nervous system?

What is the best way to describe the nervous system?

The nervous system is a complex network of nerves and cells that carry messages to and from the brain and spinal cord to various parts of the body. The nervous system includes both the Central nervous system and Peripheral nervous system.

What are the different methods used to study the nervous system?

To study the nervous system, a number of methods have evolved over time; these methods include examining brain lesions, microscopy, electrophysiology, electroencephalography, and many scanning technologies.

What is nervous system in farm animal?

The nervous system includes all the organs and tissues which enable animals to respond to changes in their environment. The nervous system of mammals is composed of two parts: the central nervous system and the peripheral nervous system.

How will you differentiate the central nervous system CNS and the peripheral nervous system PNS in terms of their function?

The Central Nervous System (CNS) includes the brain and spinal cord. The Peripheral Nervous System (PNS) connects the CNS to other parts of the body, and is composed of nerves (bundles of neurons).

What do you understand by nervous system?

The nervous system controls everything you do, including breathing, walking, thinking, and feeling. This system is made up of your brain, spinal cord, and all the nerves of your body. The brain is the control center and the spinal cord is the major highway to and from the brain.

Which method of studying the brain would most accurately?

fMRI
Therefore, psychologists can determine the activity of different brain regions with greater accuracy when using fMRI, in comparison to when using EEG, which makes fMRI an ideal choice when trying to pinpoint specific brain regions.

Which method best allows researchers to examine brain anatomy?

Which method best allows researchers to examine brain anatomy? Researchers use a variety of neuroimaging tools to study the brain. Computed tomography (CT) scans are oblique X-ray slices that show the density of brain structures.

How did animals differ in nervous system?

Diversity of Nervous Systems All animals have a true nervous system except sea sponges. Cnidarians, such as jellyfish, lack a true brain but have a system of separate but connected neurons called a nerve net. Echinoderms, such as sea stars, have neurons that are bundled into fibers called nerves.

How does the nervous system help animals live?

At the most basic level, the function of the nervous system is to control movement of the organism and to affect the environment (e.g., through pheromones). This is achieved by sending signals from one cell to others, or from one part of the body to others.

What are the differences between the CNS and PNS?

Central nervous system (CNS) consists of brain and spinal cord of the body. Peripheral nervous system (PNS) consists of dorsal and ventral root nerve cell heads, spinal and cranial nerves. Central nervous system (CNS) Controls all the voluntary functions of the body.

What is the main difference between the central nervous system and the peripheral nervous system quizlet?

What is the main difference between the central nervous system (CNS) and the peripheral nervous system (PNS)? The CNS involves the brain and spinal cord, and the PNS involves the body nerves.

What do you need to know about the nervous system?

Key facts about the nervous system Definition A network of neurons that sends, receive Divisions Central nervous system Peripheral nervou Central nervous system Brain and spinal cord Peripheral nervous system Spinal and cranial nerves. Functional di

What are the two major parts of the nervous system?

The nervous system has two major parts: the central nervous system (CNS) and the peripheral nervous system (PNS). The central system is the primary command center for the body, and is comprised of the brain and spinal cord.

How is the central nervous system like a computer?

The central nervous system is like the guts of your computer. It’s in there with millions of connections moving little impulses around from circuit to circuit (nerve to nerve), calculating and thinking. Your brain makes all the calculations and stores information.

How does the peripheral nervous system connect to the CNS?

The peripheral nervous system consists of a network of nerves that connects the rest of the body to the CNS. The two systems work together to collect information from inside the body and from the environment outside it.
