Neurons and Structure
These receive signals.
What are dendrites?
These make up the CNS.
What are the brain and spinal cord?
This division controls voluntary actions.
What is the somatic nervous system?
This processes reflexes first.
What is the spinal cord?
This disease destroys myelin.
What is multiple sclerosis?
This part contains the nucleus.
What is the cell body?
This acts as the relay station for sensory information.
What is the thalamus?
This division controls involuntary functions.
What is the autonomic nervous system?
Correct reflex arc pathway.
What is receptor → sensory neuron → spinal cord → motor neuron → effector?
Lack of oxygen to the brain results in this.
What is a stroke?
These conduct impulses away from the cell.
What are axons?
This maintains homeostasis.
What is the hypothalamus?
This is an example of autonomic control.
What is heartbeat?
Damage here most affects reflexes.
What is the spinal cord?
This inflammation affects the meninges.
What is meningitis?
This fatty substance speeds up transmission.
What is the myelin sheath?
This controls balance and coordination.
What is the cerebellum?
These cells support and protect neurons.
What are neuroglia?
If dendrites are damaged, this is affected.
What is signal reception?
This disease causes tremors and shuffling gait.
What is Parkinson’s disease?
These allow impulses to jump, speeding conduction.
What are Nodes of Ranvier?
This controls vital life functions like heart rate.
What is the brainstem?
These connect sensory and motor neurons.
What are interneurons?
If axon terminals are blocked, this happens.
What is signals cannot reach the next neuron?
Loss of myelin causes this effect.
What is slower impulse transmission?
