Quick Answer: What Is The Functional Classification Of The Nervous System?

What is the functional classification of this neuron?

Nerve cells are functionally classified as sensory neurons, motor neurons, or interneurons.

Sensory neurons (afferent neurons) are unipolar, bipolar, or multipolar shaped cells that conduct action potentials toward or into the central nervous system..

What are the three basic functions of the nervous system?

The CNS is comprised of the brain, cerebellum and spinal cord. Remaining neurons, and associated cells, distributed throughout the body form the PNS. The nervous system has three broad functions: sensory input, information processing, and motor output.

How do you explain the nervous system?

The nervous system is the part of an animal’s body that coordinates its behavior and transmits signals between different body areas. In vertebrates it consists of two main parts, called the central nervous system (CNS) and the peripheral nervous system (PNS). The CNS contains the brain and spinal cord.

What are the three main types of neurons?

For the spinal cord though, we can say that there are three types of neurons: sensory, motor, and interneurons.Sensory neurons. … Motor neurons. … Interneurons. … Neurons in the brain.

What are the functional divisions of the nervous system?

The nervous system is divided into the central nervous system and peripheral nervous system. Let’s break the central nervous system and the peripheral nervous system into more parts.

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

The human nervous system is divided into the central nervous system (CNS) and peripheral nervous system (PNS).

What are the 6 divisions of the nervous system?

The central nervous system (defined as the brain and spinal cord) is usually considered to have seven basic parts: the spinal cord, the medulla, the pons, the cerebellum, the midbrain, the diencephalon, and the cerebral hemispheres (Figure 1.10; see also Figure 1.8).

What are the 2 main functional subdivisions of the nervous system?

The nervous system as a whole is divided into two subdivisions: the central nervous system (CNS) and the peripheral nervous system (PNS).

What are the divisions of the nervous system and their functions?

The anatomical divisions are the central and peripheral nervous systems. The CNS is the brain and spinal cord. The PNS is everything else and includes afferent and efferent branches with further subdivisions for somatic, visceral and autonomic function.

What are two functional divisions of the nervous system?

Structural Divisions of the Nervous System. The nervous system can be divided into two major regions: the central and peripheral nervous systems. The central nervous system (CNS) is the brain and spinal cord, and the peripheral nervous system (PNS) is everything else (Figure 8.2).

What are the four functions of the nervous system?

The four main functions of the nervous system are:Control of body’s internal environment to maintain ‘homeostasis’ An example of this is the regulation of body temperature. … Programming of spinal cord reflexes. An example of this is the stretch reflex. … Memory and learning. … Voluntary control of movement.

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.

What is the structure and function of the central nervous system?

The central nervous system (CNS) controls most functions of the body and mind. It consists of two parts: the brain and the spinal cord. The brain is the center of our thoughts, the interpreter of our external environment, and the origin of control over body movement.

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 are the structural and functional classification of the nervous system?

The structural classification includes all the nervous system organs. … The functional classification divides the peripheral nervous system into afferent (sensory) and efferent (motor) branches. The motor division is further divided into the somatic and autonomic branches.

What are the 3 main divisions of the nervous system?

Divisions of the Nervous SystemCranial nervous system.Peripheral nervous system.Autonomic nervous system.Central nervous system.

What are the three functional classes of neurons in the nervous system?

While there are billions of neurons and thousands of varieties of neurons, they can be classified into three basic groups based on function: motor neurons, sensory neurons, and interneurons.
