What is the major organ of the central nervous system?

What is the major organ of the central nervous system?

The brain and spinal cord together form the central nervous system, or CNS. The CNS acts as the control center of the body by providing its processing, memory, and regulation systems.

What organs compose the central nervous system?

The brain and the spinal cord make up the central nervous system. The nervous system is the most complex and highly organized body system. It receives information from the sensory organs via nerves, transmits the information through the spinal cord, and processes it in the brain.

What is the most important organ in the nervous system and why?

While your heart is a vital organ, the brain (and the nervous system that attaches to the brain) make up the most critical organ system in the human body. The human nervous system is responsible for coordinating every movement and action your body makes.

Is the central nervous system an organ?

The brain and spinal cord are the organs of the central nervous system. Because they are so vitally important, the brain and spinal cord, located in the dorsal body cavity, are encased in bone for protection.

What are the main divisions of the nervous system what organs belong to each?

The central nervous system (CNS) is the brain and spinal cord, and the peripheral nervous system (PNS) is everything else (Figure 1). The brain is contained within the cranial cavity of the skull, and the spinal cord is contained within the vertebral cavity of the vertebral column.

What organelle are in the nervous system?

Organelle systems. The five cirri at the rear of the organism are connected to the anterior end in an area known as the motorium . The fibres of the motorium apparently provide coordination between the cirri and the membranelles. The membranelles, cirri, and motorium constitute a neuromotor system.

What connects your body to the central nervous system?

A “plexus” is an integral part of the nervous system where nerves are bunched together in small groups. These nerve clusters connect the peripheral and central nervous systems, allowing electrical signals to travel from the brain and spinal cord to the rest of the body.

What are the parts and functions of the nervous system?

Parts of the nervous system, the system of the body that oversees the function of all other systems, include its main organ, the brain; its vessels, the spinal cord and peripheral nerves; and its cells, known as neurons, which transmit the electrical signals that are nerve impulses.

What does the spinal cord do for the central nervous system?

The spinal cord is a track of nerves in the back. This crucial member of the central nervous system utilizes nerve cells and nerve tracts to function in several important ways. Vital spinal cord functions include providing a brain-body connection, directing movement, and housing the body’s reflex system.
