The nervous system contains: - ANS brain, brainstem, and nerves
-divided into two structural systems:
• CNS
• PNS
CNS - ANS Central nervous system
-structure: brain and spinal cord
-function: integrative and control centers
PNS - ANS Peripheral nervous system
-Structure: cranial nerves and spinal nerves
-function: communication lines between the CNS & rest of the body
Sensory (afferent) division - ANS -conducts impulses from receptors to the CNS
-somatic & visceral sensory nerve fibers
Motor (efferent) division - ANS -conducts impulses from the CNS to effectors (muscles &
glands)
-motor nerve fibers

Sympathetic division - ANS mobilizes body systems during activity
-fight or flight
Parasympathetic division - ANS -conserves energy
-promotes "housekeeping" functions during rest
Autonomic nervous system (ANS) - ANS -conducts impulses from the CNS to cardiac muscles,
smooth muscles, and glands
-visceral motor (involuntary)
Somatic nervous system - ANS -somatic motor (voluntary)
-conducts impulses from the CNS to skeletal muscles
Which symptom warrants a focused neurological exam?:
acute onset headaches
fatigue
difficulty swallowing
fever for 48 hours
hand tremors
frequently dropping objects
indigestion - ANS acute onset headaches
difficulty swallowing
hand tremors
frequently dropping objects
Rationale: Acute onset headaches, difficulty swallowing, hand tremors, and frequently dropping
objects are common neurological symptoms that would prompt a focused neurological exam.
Fever alone is not an indication for a neurological exam; however, fever in the presence of a

stiff neck and headache could indicate meningitis. Indigestion and fatigue are unrelated
symptoms that would not require a neurological exam.
nervous system is responsible for: - ANS generating and sending electrochemical signals
throughout the body
-enable the body to detect and respond to stimuli from the outside world
-Nerve signals control most bodily functions
• sensation, movement, and metabolic and digestive processes
Common Neurological Symptoms - ANS headache
dizziness or vertigo
weakness
numbness or altered sensation
fainting and syncope
seizures
tremors or involuntary movement
Neurological Assessment: Warning Signs - ANS Headaches, common client complaint, req
careful examination to rule out secondary, life-threatening causes such as meningitis,
subarachnoid hemorrhage, or a lesion
-misdiagnosis of a secondary headache can result in permanent neurologic deficits and death
-mnemonic SNOOP is a helpful red flag detection tool for identifying high-risk features in
secondary headaches
• presence 1+ red flags warrants immediate intervention
SSSNOOPPP mnemonic - ANS Systemic Symptoms & Secondary risk factors
-fever, weight loss, fatigue
-HIV, cancer, immune suppression

-infection, inflammation, metastic cancer, carcinomatous meningitis
Neurologic symptoms/signs
-altered consciousness & local deficits
-encephalitis, mass lesion, stroke
Onset
-thunderclap & abrupt
-subarachnoid hemorrhage (SAH), intraparenchymal hemorrhage (IPH), reversible cerebral
vasoconstriction syndrome (RCVS)
Order
-signs & symptoms that are new after the age of 50
-temporal arteritis
Positional, Prior headache, & Papilledema
-from upright to lying, changing neck position
-diff. in quality & progressive worsening
-papilledema: visual obscurations
-intracranial hypotension, dysautonomia, cervicogenic headache, intracranial hypertension,
posterior fossa pathology
Migraine Headache - ANS -Pain is throbbing
-May have an aura with temporary vision changes or numbness, speech problems, or muscle
weakness
-Described as moderate to severe and unilateral
-Generally lasts 4 to 72 hours
