Does neural processing input either travel along one single pathway to a specific destination or it travels along several different pathways to integrate in different cns regions but not both?
False
Does neural impulses travel faster than hormonal messages?
Nerve impulses move at nearly the speed of light. Hormones are chemicals that are released over a period of time to Crete changes in a multicellular organism. So, naturally, nerve impulses are faster.
What is the term for the conversion of physical energy into neural information?
transduction
What is another word for brain waves?
cranium rollercoasters
What is the auditory receptors where sound waves finally become neural impulses?
basilar membranes
The message that travels through a neuron?
A neural impulse. Specifically, once it fires, an action potential.
What is neural impulse?
A neural Impulse is a spike of electrical activity.
What are also called neural impulses?
Action potential is a neural impulse.
Are also called neural impulses?
Action potential is a neural impulse.
Neural impulses speed increases when the axon is encased by what?
Myelin Sheath
What generate and transmit nerve impulse?
A sensory stimulus can generate a neural impulse, as can repeated or multiple inputs of neural signals from other neurons.A neural signal is transmitted from one neuron to anotheracross a synapse via chemicals called neurotransmitters, and a neural impulse is transmitted along an axon of a neuron by either an action potential (in an unmyelinated axon) or by saltatory conduction (in a myelinated axon).
Where are action potentials regenerated as they propagate along a myelinated axon?
First at the axon hillock where the neural impulse is initially triggered, and then at the nodes of Ranvier as the impulse continues to travel along the axon.(Note that the impulse travels as electrotonic conduction between the nodes of Ranvier, underneath the glial cells which myelinate the axon.)
The state of the neuron when not firing a neural impulse is known as?
Resting potential
What do you call the state of a neuron when it is firing a neural impulse?
Resting potential.
What do you call the state of a neuron when it is not firing a neural impulse?
Resting potential.
How are hormones similar to neurotransmitters?
A neural impulse is similar to an electrical signal in three ways: 1. there are electrical voltages involved in the movement of the neural impulse; 2. an electrical signal can convey information, as can a neural impulse; 3. an electrical signal can cause an action, like a car starter switch starting the engine, and a neural impulse can cause a muscle to contract to move a limb. (note that with respect to the voltages involved in the neural impulse, the voltages are created by the movement of chemicals, charged particles called ions, somewhat similar to how batteries produce voltages.) (also note that the neural impulse is the signal which moves along the axon, as an action potential.)
What is it called when another neural impulse cannot occur?
THe absolute refractory period
