16 Cards in this Set

  • Front
  • Back
Receive chemical signals (neurotransmitters) and turn them into electrical impulses.
Dendrites
Carries the electrical impulse
Axon
Turn the electrical impulse into neurotrasmitters to be sent to the next neuron in the chain
Terminal Branches
The space between the terminal branches of one neuron and the dendrites of another is called
the Synapse
When no elecrical impulse is passing through a neuron, the neuron uses energy and a specialized protein to pump this out of the cell
three positive sodium ions (Na+)
When no electrical impulse is passing through a neuron, the neuron uses energy and a specialized protein to let in just two:
positive potassium ions (K+)
This build up of electrical voltage across the central membrane is called:
resting potential
When neurotransmitters from another neuron reach the dendrites of a cell they:
depolarize that region of the cell
When depolarization occurrs, this sets in motion a wavelike motion of these ions in and out of the cell, down the full length of the neuron to the terminal branches. This creates an electral voltage called the action potential.
NA+ and K+At the terminal branches, the arrival of the action potential causes the release of neurotransmitters int othe ____,
At the terminal branches, the arrival of the action potential causes the release of neurotransmitters int othe ________, starting the process in the next neuron.
synapse
Wraps around the axon of a cell to speed the passage of the action potential
myelin sheath
brain and spinal cord; controls basic life functions, such as breathing and circulation, as well as behavior and (in humans) abstract thinking and consciousness.
Central Nervous System (CNS)
The pathways of neurons that connect the central nervous system to the rest of the body.
Peripheral Nervous System (PNS)
This part of the Peripheral Nervous System carries information from the body to the central nervous system.
Sensory System. Neurons in this system are called sensory neurons.
This part of the Periheral Nervous System carries instructions to the muscles and causes those muscles to move by releasing the neurotransmitter acethylcholine.
Motor System
The Motor System can be divided into the ________ system that controls ovluntary movement, and the ________ system whic controls involuntary movement.
Somatic and Autonomic
