topic 7 ppt notes

What is the role of a sensory (afferent) neuron?

• Transmits signals from the CNS to effectors

• Transforms energy from one form to another

• Transmits signals from receptors to the CNS

• Uses action potentials as energy

What does the term "transduction" refer to in the context of neurons?

• Using action potentials as energy

• Transforming energy from one form to another

• Transmitting signals from effectors to the CNS

• Transmitting signals from the CNS to effectors

What is the function of an interneuron?

• Transmits signals from receptors to the CNS

• Connects sensory and motor neurons

• Transmits signals from the CNS to effectors

• Uses action potentials as energy

How do we bring the sensory neuron to threshold?

• By increasing the action potential

• By transforming energy from one form to another

• By connecting it to an effector

• By using action potentials as energy
