Neurons
What is the type of neuron we went over in class?
Motor Neuron
stimuli
What are the two main parts of The Human Nervous System?
Central Nervous System and Peripheral
What is the CNS made up of?
Brain and Spinal Cord
There is a gap between one neuron to another during synapses. If false, explain.
True
Axons transmit electrical impulses away from cell body to other cells.
listeners that pick up "gossip" from other cells and convey info to cell body. Is involved with synapses.
What does the nervous system do?
Coordinates all of the activities in the body
What is the PNS made up of?
Nerves that extend from and connect the CNS to the rest of the body.
You guys have homework!
YES
What are the three main parts of a neuron?
1) Cell Body
2) Dendrites
3) Axons (includes nerve ending)
Effectors
parts of the body that respond to the stimuli
What does the CNS do?
Coordinate the electrical impulses traveling through the nervous system.
What do the Cell body consist of? (name 3)
Nucleus, Mitochondria, and Cytoplasm, ribosomes, cell membrane, DNA
Relay neurons connect sensory neurons to motor neurons within the PNS. If false, say why.
False, it is in the CNS.
Difference between neurone and nerves.
What are Reflex Arc?
the pathway our nervous system takes to automatically react to a stimulus.
Difference between voluntary vs. involuntary movement. Give an example of each.
Voluntary- brain makes decision and then reaches motor neuron.
Involuntary- Automatic movements that only reach spinal cord then to motor neurone.
When do neurones use chemical signals?
During synapses.
The way neurons talk is from nerve ending to nerve ending. If false explain how.
False, it is from the nerve ending of one neurone to dendrites of another.
