A&P ANS
Flashcards do conjunto (16)
- 1Parasympathetic"Rest and Digest"
-Conserves energy
-Promotes maintenance functions
-Craniosacral origins (Cranial and sacral or Head and sacrum)
-Ganglia closer to the tissue (further from spinal cord) - 2Sympathetic"Fight or flight"
-Uses energy
-Thoracolumbar origins (Thoracic and lumbar origins)
-Ganglia closer to the spinal cord
-Skin and adrenal glands are only in the sympathetic - 3The autonomic nervous system helps maintain homeostasis.IF YOU MODIFY ANYTHING OF THIS YOU WON’T FEEL GOOD
Regulated by the ANS
Heart rate
Breathing
Defecation
Thermoregulation
Blood pressure
Digestion
Urination
Osmoregulation - 4KNOW THIS CHART
- 5Control center-Control center is in the brain stem and spinal cord
-Everything goes through the spinal cord
-What your skeletal muscle does is due to your ANS
(Sensory neurons -> Control center -> ANS motor neurons -> Visceral effector) - 6Control centers
- 7Duel innervation-Receives 2 signals from 2 divisions (Parasym and Sym)
-Works together
-Uses both division - 8Dynamic antagonism-Changing often
-Works against each other
-Uses on system or the other - 9Parasympathetic responses"Rest and digest"
SLUDD
Increased when Parasympathetic is active
Salvation
Lactation
Urination
Digestion
Defecation
Decrease heart rate, bronchial diameter, and pupil diameter - 10Sympathetic"Fight or flight"
-Increase heart rate, bronchial diameter, and pupil diameter
-Lasting longer and widespread because of hormones and takes longer to leave your body
-"E situation" Excited, exercise, embarrassment, emergency - 11How they work togetherParasym - relaxs - blood flow in and out - erection
Sym - orgasms or ejaculation - 12Brain stem-Medullary centers regulate heart rate and blood vessel diameter, breathing rate and bronchiole diameter, as well as gastrointestinal activities.
-Midbrain controls muscles of pupil and lens. - 13Spinal cord-Controls defecation and urination, but are subject to conscious override
- 14Hypothalamus-Regulates everything then tells medulla what to do
-Anterior regions direct parasympathetic functions; posterior region directs sympathetic.
-Hypothalamic centers control heart activity, blood pressure, body temperature, water balance, and endocrine activity.
-Emotional responses activated through limbic system signal hypothalamus to activate the sympathetic nervous system. - 15Parasympathetic summary
