Sympathetic Nervous System
"Fight or flight" Stress response -Heart rate, blood pressure, pupil size -Think about realizing that you are about to be in a bad situation—as you realize this, your body goes into fight or flight. Thinking quick on feet. -Increased HR, BP, RR-because more oxygen is needed to figure out a strategic move and nutrients to muscles to help with the fight -Pupil size will dilate to let in as much information as possible.

Edema of the eyelids and conjunctival injection may be associated. Unilateral exophthalmos is seen in Graves disease or a tumor or inflammation in the orbit. "Dizziness" is a nonspecific term used by patients encompassing several disorders that clinicians must carefully sort out. A detailed history usually identifies the primary etiology. It is important to learn the specific meanings of the following terms or conditions:

After 20 seconds tap downwards on alternating arms -If abnormal arm will drift downward, palm pronates, or unable to find original point. Indicative if motor neuron disease or metabolic disease
Peripheral Nerve
BUNDLE OF FIBERS OUTSIDE THE CENTRAL NERVOUS SYSTEM (CNS); AND THERE ARE TWO TYPES OF FIBERS: AFFERENT: SENSORY MESSAGES TO THE CNS FROM SENSORY RECEPTORS (DANG THAT IS HOT) EFFERENT: MOTOR MESSAGES FROM THE CNS OUT TO THE MUSCLES, ORGANS, AND GLANDS. (THE MOTION OF MOVING YOUR HAND WHEN ITS HOT). --Effect of that feeling -AUTONOMIC NERVOUS SYSTEM

Conductive hearing loss
Migraine headaches
Process: Neuronal dysfunction, possibly of brainstem origin, involving low serotonin level, spreading cortical depression and trigeminovascular activation; types: with aura, without aura, variants Lifetime Prevalence: 10% of headaches; prevalence 18% of U.S. adults; affects ∼15% of women, 6% of men Location: Unilateral in ∼70%; bifrontal or global in ∼30% Quality and severity: Throbbing or aching, pain, moderate to severe in intensity; preceded by an aura in up to 30% Onset: Fairly rapid, reaching a peak in 1-2 hours Duration: 4-72 hours Course: Recurrent—usually monthly, but weekly in ∼10%; peak incidence early to mid-adolescence Associated symptoms: Prodrome: nausea, vomiting, photophobia, phonophobia; aura in 30%; either visual (flickering, zig- zagging lines), or motor (paresthesias of hand, arm, or face, or language dysfunction) Triggers/Factors That Aggravate or Provoke: Alcohol, certain foods, or stress may provoke; also menses, high altitude; aggravated by noise and bright light Factors That Relieve: Quiet, dark room; sleep; sometimes transient relief from pressure on the involved artery
Tension headache
Process: Process unclear—possibly heightened CNS pain sensitivity. Involves peri cranial muscle tenderness; etiology also unclear Lifetime prevalence: Most common headache (40%); prevalence about 50% Location: Usually bilateral; may be generalized or localized to the back of the head and upper neck or to the frontotemporal area Quality and severity: Steady; pressing or tightening; no throbbing pain; mild to moderate intensity Described in onset, duration, course Gradual onset Duration- 30 minutes to 7 days Sometimes photophobia, phonophobia; scalp tenderness; nausea absent Triggers/Factors That Aggravate or Provoke: Sustained muscle tension, as in driving or typing; stress; sleep disturbances Factors That Relieve: Possibly massage, relaxation
Ptosis
Ptosis is a drooping of the upper lid. Causes include myasthenia gravis, damage to the oculomotor nerve, and damage to the sympathetic nerve supply (Horner syndrome). A weakened muscle, relaxed tissues, and the weight of herniated fat may cause senile ptosis. Ptosis may also be congenital.
The nurse is testing the function of cranial nerve VII. Which of the following best describes the response the nurse would expect if the nerve is intact?

How do you inspect the ear canal in children?
Pull ear down and back to straighten ear canal
To inspect an adult's ear canal, what do we do?
Pull ear up and back to straighten the canal -Look for color, edema, discharge, and cerumen -Look at tympanic membrane color, perforation, and bulge
Neurological structure/function - reflexes
Reflexes (automatic = autonomic) - DTR (STRIKING THE KNEE WITH THE HAMMER) - Superficial (corneal reflex, abdominal reflex) -DON'T NORMALLY DO THIS TO PEOPLE AWAKE - Visceral (pupillary response to light, COUGH REFLEX, gag) - Pathologic- (abnormal: present Babinski in adult) -brain is decompensating to the form of an infant -Variant of normal—happening because of disease process REFLEXES ARE: - INVOLUNTARY - HELPS MAINTAIN MUSCLE TONE - PROTECTS- PERMITS QUICK RESPOSE TO BAD STIMULI
External auditory canal

Sensorineural
FAST
Signs of a stroke Facial drooping Arm weakness Speech differences Time to call 911
Eyes- objective data of visual acuity
Snellen vision acuity chart -Chart is 20 feet away from the patient. We are going to test by cover one eye during testing, then switch to the other eye, then both eyes -The larger the denominator= the poorer the vision -20/200= legally blind -Myopia: nearsighted Can't see things far away -Hyperopia: farsighted Can't see things that are close -Presbyopia: decreased accommodation with aging and needs to move object farther away to see it Ex: I have 20/100 vision means at 20 feet I can see what normal people can see at 100 feet
