What are the functions of the CNS?

What are the functions of the CNS?

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 supporting cells of the CNS what are their functions?

In the central nervous system, there are four types of supporting cells.

• Oligodendrocytes. The axons of many neurons are insulated by a myelin sheath, which increases the rate at which an axon can conduct an action potential.
• Microglia. These types of cell are less common.
• Astrocyte.
• Ependymal cells.

What are the 3 elements of the CNS?

What are the parts of the nervous system?

• 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.

Whats is CNS?

The brain and spinal cord. Also called central nervous system. Enlarge. Anatomy of the brain, showing the cerebrum, cerebellum, brain stem, and other parts of the brain.

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 is the function of the central nervous system quizlet?

The main functions of the central nervous system is to PROCESS information received through sensory systems and other parts of the body and to activate appropriate actions to the external/internal stimuli.

What is CNS short answer?

Central nervous system (CNS): The central nervous system is that part of the nervous system that consists of the brain and spinal cord. The central nervous system (CNS) is one of the two major divisions of the nervous system. The other is the peripheral nervous system (PNS) which is outside the brain and spinal cord.

What are the 4 Neuroglia of the CNS?

Based upon their appearance, function, and origin, four types of glial cells have been identified in the central nervous system: astrocytes, oligodendroglia, ependymal cells, and microglia.

What are the two main parts of CNS?

The nervous system has two different major parts. The two parts are the central nervous system and the peripheral nervous. The central nervous system or the CNS contains the brain and the spinal cord. All together, the brain and the spinal cord serve the nervous system’s command station.

What are the functions of the three neurons?

The Basic Functions of a Neuron. All neurons have three basic functions. These are to: Receive signals (or information). Integrate incoming signals (to determine whether or not the information should be passed along). Communicate signals to target cells (other neurons or muscles or glands).

What are the most common CNS disorders?

These include a group of CNS disorders which consist of: Small artery stroke, large vessels ischemia, carotid atherosclerosis, ischemic shock etc. Cerebrovascular diseases include some of the most common and devastating CNS disorders: ischemic stroke and hemorrhagic stroke.

What structures are part of the CNS?

Basic Structures. The CNS consists of the brain and spinal cord, while the PNS includes all other nervous system tissue. All sensory receptors, sensory neurons and motor neurons are part of the PNS. The bones of the skull and spinal vertebrae encase all CNS neurons.
