Autonomic Nervous system Flashcards
System that controls the involuntary smooth muscle, cardiac muscle and glandular tissue
Autonomic Nervous system
Autonomic Nervous system is highly integrated by what part of the brain
Hypothalamus
Reflex in ANS often involve what structures
Medulla oblongata
Spinal cords
2 Divisions of ANS
Parasympathetic
Sympathetic
Parasympathetic is also known as
Rest or Digest
Origin of Parasympathetic
Craniosacral (S2-4)
Neurotransmitter in the Pre-Ganglionic of ANS
Acetylcholine
Neurotransmitter in the Post-Ganglionic of ANS
Acetylcholine
Receptor cells in ANS
Nicotinic
Muscarinic
Nicotinic receptor cells are found
Skeletal muscle
Adrenal gland
Skeletal muscle contraction in parasympathetic
Decreased
Chromaffin cell activity in Parasympathetic
relaxes
Muscarinic receptors are found
M1-CNS, Gastruc parietal cells, Salivary gland
M2- Heart
M3- Glands (Lacrimal, salivary, Gastric, Sweat and Bronchial glands) Smooth muscle (Brinchioles, Eyes, GI smooth muscle, Vascular endothelium, Bladder, Genitalia)
Acid secretion in stomach of parasympathetic
Increased
Peristaltic activity in Parasympathetic
Increased
What is peristalsis?
contraction of intestines
Contraction of Urinary Bladder in Parasympathetic
Increased
Pupil during parasympathetic
Miosis
Cardiac output in Parasympathetic
Bradychardia
Respiratory rate in Parasympathetic
Bradypnea
Salivary gland production in Parasympathetic
Increased
Condition of male reproductive organ (penis) during parasympathetic
Erect
Glands that are controlled by sympathetic fibers but with Cholinergic receptor cells
Sweat gland
Adrenal gland
Also known as the fight or flight response
Sympathetic
Other term for sympathetic
Fight or flight
Adrenaline rush
Origin of Sympathetic
Thoracolumbar
Pre-Ganglionic neurotransmitter of sympathetic____
Post-Ganglionic _______
Acetylcholine
Norepinephrine
Receptor cells of sympathetic
Alpha
Beta
Sympathetic receptor cell responsible for vasoconstriction
Alpha1
sympathetic receptor cell responsible for decreased acid secretion and decreased peristaltic activity
Alpha 2
immediate precursor of epinephrine
Norepinephrine
T/F: Epinephrine is less potent than Norepinephrine
False
T/F: Epinephrine is more toxic than Norepinephrine
True
Chromaffin cells produces what neurotransmitters
Epinephrine and Norepinephrine
Sympathetic receptor that produces tachycardia and decreases salivary secretion.
Beta 1
Beta 1 more common in what organ?
Heart
Type of mucus produce during sympathetic state
Mucus production
Sympathetic receptor cell that is responsible for tachypnea, increased muscle contraction
Beta 2
T/F: Ejaculation occurs during Sympathetic
True
