What else can I help you with?
What is the central nervous?
The central nervous system is the brain and spinal cord. The branches from the brain and cord are called the peripheral nervous system.
What is the main control area of the nervous system called?
The central nervous system or CNS
What are the brain and nervous system collectively called?
Those parts of the body are simply called the central nervous system.
Information entering the central nervous system from the external environment is called what?
Information entering the central nervous system from the external environment is called external stimuli. External stimuli are factors which are detected by the body and communicated to the central nervous system such as temperature and scents.
What is the name of the protective insulation that surrounds parts of neurons and speeds the transmission of electrical impulses along brain cells?
The protective insulation surrounding neurons is called myelin. Myelin is produced by cells called oligodendrocytes in the central nervous system and Schwann cells in the peripheral nervous system, and it helps to increase the speed and efficiency of electrical impulse transmission along the neuron.
What best describes the waxy-appearing material called myelin?
Myelin is a fatty substance that forms a protective sheath around nerve fibers, helping to increase the speed and efficiency of nerve signal transmission. It is produced by specialized cells called oligodendrocytes in the central nervous system and Schwann cells in the peripheral nervous system. Its waxy appearance comes from its high lipid content.
What is the division of the nervous system that controls the brain and spinal cord called?
The Central Nervous System
What is the brain and spinal cord collectively called?
The Brain and Spinal Chord comprise the Central Nervous System.
The fluid in the central nervous system is called?
Cerebrospinal Fluid
What the support cell in central nervous system?
These are called neuroglia.
What do the brain and the spinal cord together make up?
The brain and the spinal cord make up what is called the central nervous system.
What is a group of nerve fibers in the central nervous system is called a?
nucleus
