What Term Describes This Flexibility Within The Nervous System?

How do you describe the nervous system?

The nervous system is a complex collection of nerves and specialized cells known as neurons that transmit signals between different parts of the body.

It is essentially the body’s electrical wiring.

Structurally, the nervous system has two components: the central nervous system and the peripheral nervous system..

What are the two major subdivisions of the nervous system?

The nervous system can be divided into two major subdivisions: the central nervous system (CNS) and the peripheral nervous system (PNS), shown in [link]. The CNS is comprised of the brain and spinal cord; the PNS connects the CNS to the rest of the body.

How does the nervous system work with the muscular system?

Muscular System: The brain uses the nerves to tell the muscles when to move. The nerves also deliver information on what to do in a fight or flight case. Respiratory System: The brain sends pulses through the nerves to the lungs which tell them to move to collect and release oxygen and carbon dioxide.

What is the relationship between the two parts of the nervous system?

It is divided into two parts. The sympathetic nervous system mobilizes energy and resources during times of stress and arousal, while the parasympathetic nervous system conserves energy and resources during relaxed states, including sleep.

What are the 2 parts of the nervous system called?

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 stimulus in nervous system?

They detect a change in the environment (stimulus). In the nervous system this leads to an electrical impulse being made in response to the stimulus. Sense organs contain groups of receptors that respond to specific stimuli.

What are the 3 types of nervous system?

There are three types of nerves in your body: autonomic nerves, motor nerves, and sensory nerves.

What are the top 3 common nervous system disorders?

Examples include:Parkinson’s disease.Multiple sclerosis (MS).Amyotrophic lateral sclerosis (ALS).Alzheimer’s disease.Huntington’s disease.Peripheral neuropathies.

What is nervous system and types?

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).

Why is the nervous system most important?

The nervous system helps all the parts of the body to communicate with each other. It also reacts to changes both outside and inside the body. The nervous system uses both electrical and chemical means to send and receive messages.

Who discovered the nervous system?

HerophilusHerophilus was the first to examine and report on the structure of the nervous system. He was able to do this by dissecting human cadavers [15], a practice that was in many places abandoned until the 16th Century [16]. This method allowed him to make many discoveries.

How does the central nervous system affect behavior?

The central nervous system has a fundamental role in the control of behavior. It contains the brain and the spinal cord which are both encased in bone which shows their importance. Both the brain and spinal cord receive signals from the afferent neurons and send signals to muscles and glands through efferent neurons.

What are cells within the nervous system called?

Cells of the Nervous System. There are two broad classes of cells in the nervous system: neurons, which process information, and glia, which provide the neurons with mechanical and metabolic support. Three general categories of neurons are commonly recognized (Peters, Palay, & Webster, 1976).

What are the two main subdivisions of the nervous system quizlet?

The structures of the nervous system are described in terms of 2 principal divisions-the central nervous system (CNS) and the peripheral nervous system (PNS).

What is the nervous system in simple terms?

The nervous system is a system in the body which sends signals around the body. It lets people and animals respond to what is around them. The central nervous system is the brain, the spinal cord, and nerves. It is present in most animals. … The brain has billions of nerve cells to help think, walk, and breathe.

What is the main function of the peripheral nervous system?

The peripheral nervous system (PNS) is the division of the nervous system containing all the nerves that lie outside of the central nervous system (CNS). The primary role of the PNS is to connect the CNS to the organs, limbs, and skin.

What are the 4 parts of the peripheral nervous system?

The PNS is divided into the somatic and autonomic nervous systems. The somatic system controls voluntary activities, whereas the autonomic system controls involuntary activities. The autonomic nervous system is further divided into sympathetic, parasympathetic, and enteric divisions.

What is nervous system and its function?

The nervous system consists of the brain, spinal cord, sensory organs, and all of the nerves that connect these organs with the rest of the body. Together, these organs are responsible for the control of the body and communication among its parts.
