The Primary Problem in Hyperkalemia Is

question 185

Multiple Choice

The primary problem in hyperkalemia is

• A) that neurons are harder to excite because their resting potential is hyperpolarized.
• B) that neurons are hyperexcitable because their resting potential is closer to threshold.
• C) that neurons respond too quickly to smaller graded potentials.
• D) neurons are harder to excite because their resting potential is hyperpolarized and neurons respond too quickly to smaller graded potentials.
• E) neurons are hyperexcitable because their resting potential is closer to threshold and neurons respond too quickly to smaller graded potentials.

Definitions:

Chemical Synapses

Sites where neurons communicate with each other or with effector organs through chemical messengers.

Electrical Synapses

Specialized junctions between cells that allow for the direct passage of ions and electrical signals, facilitating rapid communication.

Amine Neurotransmitters

Amine neurotransmitters are chemical messengers derived from amino acids that transmit nerve impulses across synapses, including serotonin, dopamine, and norepinephrine.

Sensory Synapses

The connection points between sensory neurons and their target cells, where the transmission of sensory information takes place.
