Anatomy
Part of the brain responsible for muscle tone, coordination, and maintaining balance
What is the cerebellum?
Part of the neuron leading from the cell body; some are covered in myelin, which helps speed up the impulse
What is the axon?
The brain and spinal cord compose the section of the nervous system
What is the central nervous system?
Not a characteristic of ALS
Loss of hearing, sight, speech, taste, or bladder control
When doing a reflex test on the pupils of the eye, what are you testing?
What is the Optic Nerve. Testing for nerve damage or a head injury
Part of the brain that controls breathing, heartbeat and the size/diameter of blood vessels
What is the medulla oblongata?
Chemical substances at the end of an axon which help the nervous impulse cross the synapse to the next neuron
What are neurotransmitters?
The cranial and spinal nerves are part of this section of the nervous system
What is the peripheral nervous system?
Commonly known as 'seizure disorder'
What is epilepsy?
Test involving recording the electrical activity of the brain
What is an EEG/electroencephalogram?
Part of the nerve cell/neuron that first receives the impulse/message
What is dendrite?
White lipid coating on some axons which helps speed up the transmission of the nerve impulse
What is myelin/myelin sheath?
Section of nervous system that is responsible for the 'fight or flight' response
What is the sympathetic nervous system?
BONUS x2 - What does the acronym F A S T stand for (each Letter)
What is:
F - Face A - Arm S-Speech T-Time
Disorder involving deficiency of the neurotransmitter dopamine; classic signs are shuffling gain, tremors, 'pill-rolling', lack of facial expression
What is Parkinson's Disease?
Space between nerve cells
What is the synapse?
Characteristic of the myelin sheath
There can be up to 300 layers
Insulates the axon
Speeds the never impulse
'Rest and digest' describes the actions of the section of the nervous system
What is the parasympathetic nervous system?
Disorder which involves gradual loss of control over voluntary and then involuntary muscles; mind is not affected; no cure
What is ALS/Lou Gehrig's disease?
A type of neural tube defect where the spinal cord may protrude through malformed vertebrae (occurs during fetal development); most of these can be prevented by adequate Vitamin B9 intake by the mother
What is spina bifida?
Neurotransmitter involved in Pleasurable Experiences
Dopamine
Not a type of Neuron -
Interneuron
Anterior Neuron
Sensory Neuron
Motor Neuron
Anterior Neuron
The two main divisions of the peripheral nervous system
What are the somatic and autonomic divisions of the nervous system?
Autoimmune disorder which involves demyelination of neurons/axons
Gradual, progressive dementia with amyloid deposits and senile plaques present in the brain
What is Alzheimer's?
