Central Nervous System - -brain
-spinal column
Peripheral Nervous System - -sensory nerves
-motor nerves
Cranial nerves important for OMS - -trigeminal nerve (5th)
-facial nerve (7th)
-vagus nerve (10th)
Trigeminal nerve - -sensory/motor
-Ophthalmic
-Maxillary
-Mandibular
Facial nerve - -motor nerves for facial expression
Spinal nerves - -motor/sensory nerves that leave various tracts throughout the body
Autonomic Nervous System - -sympathetic
-parasympathetic
Sympathetic Nervous System - -fight/flight
-speeds things up
-vasoconstriction
-increases hr
-MAINTAINS BP
Parasympathetic Nervous System - -rest/digest
-slows things down
-vagus nerve (slows hr and cardiac output)
-increases digestion
-increase saliva/pharyngeal production
, baroreceptors - -regulates bp with positional changes
Sympathetic (Adrenergic) - -alpha (vasoconstriction)
-beta 1/ beta 2
Beta 1 - -heart
-increase hr and strength of contraction
Beta 2 - -lungs
-bronchodilation
atria - -receive blood
right atrium - -receives blood from body peripheral circulation
-oxygen poor
left atrium - -receives blood from lungs via pulmonary vein
-oxygen rich
ventricles - -receive blood from atria
right ventricle - -deoxygenated blood to lungs
left ventricle - -sends oxygenated blood to the body
-pumps harder, thicker walls
Right atrium recieves blood from these oxygen depleted sources - -superior vena cava
-inferior vena cava
-coronary sinus
Pulmonary vein - -Oxygen rich blood
arteries - -away from heart
-thicker walls
-elastic for constriction and dilation
vein - -leading to the heart
-deoxygenated blood back to heart
ischemia - -weakened heart
-decreased oxygen supply
-angina pectoris (chest pain)
myocardial infarction - -heart attack
-death of tissue, lack of blood
