Term
List the parts to a neuron
Definition
Cell Body, Dendrite, Axon
Term
What makes up the Central Nervous System?
Definition
The Brain and its cranial nerves and the spinal cord
Term
Describe a Neuron.
Definition
It has a several short dendrites that receive messages, a cell body that contains the nucleus, and a long axon that sends messages to the next structure
Term
Where is the nucleus in a neuron?
Definition
In the cell body
Term
Which structure receives messages from other neurons or structures?
Definition
the dendrites
Term
Which structure sends messages to another neuron or structure?
Definition
the axon
Term
What is a synapse?
Definition
This is the gap between one neuron and the next
Term
What is a neurotransmitter?
Definition
This is a chemical substance that sends the message from one neuron to the next
Term
What is a neurotransmitter?
Definition
This is a chemical substance that sends the message from one neuron to the next
Term
What is the brain stem?
Definition
This is a structure attached to the brain that is responsible for basic and automatic activities such as breathing, swallowing, heartbeat, and blood pressure.
Term
What is the cerebellum?
Definition
This is the largest part of the human brain. Its functions include being responsible for thought, language, the 5 senses, voluntary movement, and memories.
Term
What is the spinal cord?
Definition
It is a long column of nerves that is encased in the vertebrae and runs from the brain all the way to the tailbone.
Term
What is the limbic system?
Definition
This is a part of the cerebrum in the brain that is responsible for functions related to emotion and behavioral responses.
Term
What is the grey matter?
Definition
This is the part of the brain tissue that is responsible for the activities associated with higher thought.
Term
What is white matter?
Definition
This is nervous tissue that is covered in myelin which is a fatty insulating tissue.
Term
What makes up the Peripheral Nervous System?
Definition
This is made up of all the nerves throughout the body (outside the Central Nervous System).
Term
What is a sensory nerve?
Definition
This is a nerve that carries messages from the body to the brain. These will indicate sensations such as pain, pressure, and temperature.
Term
What is a motor neuron?
Definition
These are nerves that carry messages from the brain to the body that activate a movement in response to a stimulus.
Term
What is paralysis?
Definition
This is when there is a loss of sensation and a loss of the ability to move a body part - this is usually due to an injury to the brain or spinal cord.
Term
What is a concussion?
Definition
This is caused by a hard blow to the head and can cause a a temporary disturbance to the the brain's function.
Term
What is Parkinson's Disease?
Definition
This is caused when there is not enough neurotransmitter produced so messages are not transmitted properly. This can cause tremors and rigid muscles.
Term
What is Alzheimer's Disease?
Definition
This is related to a gradual shrinking of neurons in the cerebrum of the brain. This can result in problems such as memory loss, emotional disturbances, and the inability of function on your own.
Term
What is Epilepsy?
Definition
This is when there is an abnormal transmission of messages between neurons in the brain. This results in seizures.
Term
What are the 5 senses?
Definition
Smell, sight, touch, taste, and hearing
