Question: What are the two basic functional units of the nervous system?

Although the nervous system is very complex, nervous tissue consists of just two basic types of nerve cells: neurons and glial cells. Neurons are the structural and functional units of the nervous system. They transmit electrical signals, called nerve impulses.

What are the two basic units of the nervous system?

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 are the functional units of the nervous system?

Neurons are the basic functional units of the nervous system, and they generate electrical signals called action potentials, which allow them to quickly transmit information over long distances.

What are the two nervous systems functions?

The nervous system can be divided into regions that are responsible for sensation (sensory functions) and for the response (motor functions).

What is the basic functional unit of the nervous system quizlet?

The basic functional unit of the nervous system is the neuron.

What is basic unit of neuron system *?

The basic unit of the nervous system is a nerve cell or a neuron. The human brain comprises about a hundred billion neurons. A neuron has a cell body, which includes the cell nucleus, and special extensions called axons.

What is the function and basic structure of 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 three basic functions of the nervous system?

Divisions of the Nervous System

The nervous system has three broad functions: sensory input, information processing, and motor output.

What are the two function of dendrites?

The functions of dendrites are to receive signals from other neurons, to process these signals, and to transfer the information to the soma of the neuron.

What are the 4 main 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.

Which of the following is an example of basic nervous system function?

The nervous system takes in information through our senses, processes the information and triggers reactions, such as making your muscles move or causing you to feel pain. For example, if you touch a hot plate, you reflexively pull back your hand and your nerves simultaneously send pain signals to your brain.

What are the main functions of the nervous system quizlet?

The primary function of the nervous system is to collect a multitude of sensory information; process, interpret, and integrate that information; and initiate appropriate responses throughout the body.

What are the two processes of a neuron?

Two processes present in neuron is Axon and dendrites. Dendrites are responsible for receiving signals coming towards the cell body. Axons help in transmitting this impulses to a long distance from the cell body towards the axon terminal.

What are the 4 types of Neuroglial cells and their functions?

Terms in this set (4)

  • Astrocytes. attach to blood vessels, star-shaped cells, provide nourishment and support.
  • Oligodendrocytes. form myelin in brain and spinal cord.
  • Microglia. fagocytic- if bacteria comes in brain it will clean them out/ help fight brain damage.
  • Ependymal.

What tissue is conductive and acts as the functional unit of the nervous system?

Neurons are the conductive cells of nervous tissue. Neurons are the functional unit of nervous system because various functions of the neural systems are basically the functions of neurons. On an average, human brain is made up of more that 100 billion neurons.
