Nervous System Flashcard

Front

What do adrenergic receptors do in the body to the eyes?

Back

Adrenergic receptors dilate pupils.

Front

How do adrenergic agonists treat patients during shock?

Back

Adrenergic agonists increase blood pressure.

Front

What are the three receptors associated with the sympathetic nervous system (SNS)?

Back

The three receptors are Alpha, Beta, and Gamma.

Front

What are the effects of an adrenergic blocker?

Back

Adrenergic blockers decrease blood pressure.

Front

What effect does the parasympathetic nervous system have on heart rate?

Back

The parasympathetic nervous system decreases heart rate.

Front

Define adrenergic receptors.

Back

Adrenergic receptors are proteins that respond to adrenaline and noradrenaline, mediating the effects of the sympathetic nervous system.

Front

What is the role of the sympathetic nervous system?

Back

The sympathetic nervous system prepares the body for 'fight or flight' responses, increasing heart rate and blood flow to muscles.

Front

What is the role of the parasympathetic nervous system?

Back

The parasympathetic nervous system promotes 'rest and digest' activities, decreasing heart rate and increasing digestive activities.

Front

What is the function of alpha receptors?

Back

Alpha receptors primarily cause vasoconstriction and increase blood pressure.

Front

What is the function of beta receptors?

Back

Beta receptors primarily cause vasodilation and increase heart rate.
