Norepinephrine and dopamine are examples of transmitters whose synaptic activity

Question

Norepinephrine and dopamine are examples of transmitters whose synaptic activity is terminated by calcium influx. O degradation. reuptake. O passive diffusion. Which sequence presents presynaptic events in the correct chronological order? O Action potential reaches axon terminal calcium ion channels open exocytosis diffusion of neurotransmitter O Exocytosis calcium ion influx action potential reaches axon terminal membrane depolarization o calcium ion influx action potential reaches axon terminal vesicle fuses with membrane diffusion of neurotransmitter O Action potential reaches axon terminal calcium ion channels open neurotransmitter diffusion exocytosis The absolute refractory period refers to the brief period of time during which a postsynaptic receptor cannot bind another neurotransmitter following a response to any hyperpolarizing input after a neuron has fired an action potential, during which the same neuron cannot fire another action potential. after exocytosis and before the release of more neurotransmitter from the presynaptic cleft. In the knee-jerk reflex, the motor neuron releases acetylcholine to stimulate the sensory neuron the stimulus activates a sensory neuron with a cell body in the ventral horn of the spinal cord. there are two synapses from stimulation to muscle contraction. a muscle stretch receptor is activated by a spinal cord motor neuron.

Explanation / Answer

Norepinephrine and dopamine are examples of transmitters whose synaptic activity is terminated by

Which sequence presents presynaptic events in the correct chronological order?

The absolute refractory period refers to the brief period of time:

In the knee-jerk reflex:

The _____ predicts the voltage that develops when a semipermeable membrane separates different concentrations of ions. The measured value of the resting membrane potential varies slightly from this predicted value because the cell is somewhat permeable to

Which of the following is an example of divergence?

A patient has a seizure that does not involve the entire brain. Just before the seizure, the patient had an unusual sensation, and at the height of the seizure, the patient was unresponsive. This patient most likely experienced a ___ seizure.

Which characteristic is not associated with slow synapses?

The size of the gap between the presynaptic membrane and the postsynaptic membrane in a chemical synapse is

At the peak of the axon potential, the axonal membrane approaches equilibrium potential for

The resting membrane potential is
