More on the Brain
100
The system is made up of the brain and spinal cord.
What is the nervous system?
100
These are cells that can transfer an impulse.
What is a neuron?
100
An immediate inborn reaction to a stimulus.
What is a reflex?
100
The largest portion of the brain that is divided into two dome-shaped halves.
What is the cerebrum?
100
This lobe is located in the back of the cerebrum and receives impulses from the nerves of the eye and interprets them as vision.
What is the occipital lobe?
200
This system includes the sense organs, such as the eyes, ears, and so on.
What is peripheral nervous system?
200
These branch off the cell body of the neuron as extensions.
What are dendrites and axons?
200
This controls reflexes in your body.
What is a reflex arc?
200
The two-dome shaped halves of the brain.
What are hemispheres?
200
These are located under the parietal lobe and receive impulses from the ear and interpret sound.
What are the temporal lobes?
300
These are the two main systems that control and coordinate the body's various activities.
What are the nervous system and the endocrine system?
300
These are short branchlike extensions that carry imulses toward the cell body.
What are dendrites?
300
This is responsible for sensing stimuli and carrying impulses to the central nervous system.
What is a reflex arc?
300
The outer layer of the cerebrum.
What is the cerebral cortex?
300
These are immediately behind the frontal lobes and deal with sensations such as pain, pressure, temperature, touch, and part of taste.
What are the parietal lobes?
400
The central nervous system is made composed of these two organs.
What are the brain and the spinal cord?
400
These are longer extensions and carry impulses away from the cell body.
What are axons?
400
These neurons act as a go-between for the sensory neuron and the motor neurons.
What is an interneuron?
400
Deep folds divide each hemisphere into four...
What are lobes?
400
This is the second largest part of the brain. It monitors and controls bodily movements without your body knowing about it.
What is the cerebellum?
500
This system branches off the central nervous system.
What is the peripheral nervous system?
500
These long, thin branches go to sensory organs, muscles, and many other structures of the body and are located outside the central nervous system
What are nerves?
500
This neuron receives the impulse from the interneuron and is responsible for producing movement.
What is a motor neuron?
500
This lobe controls consciousness and primary body movements.
What is the frontal lobe?
500
This is below and between the cerebrum and the cerebellum and helps control breathing, heartbeat, blood, pressure, coughing, sneezing, and swallowing.
