Study Notes
Behaviour Response
- Eye-opening responses are categorized as:
- Spontaneous (4)
- To speech (3)
- To pain (2)
- No response (1)
- Verbal responses include:
- Oriented (5)
- Confused (4)
- Inappropriate words (3)
- Incomprehensible sounds (2)
- No response (1)
- Motor responses are assessed by:
- Obeying commands (6)
- Moving to localized pain (5)
- Flexing to withdraw from pain (4)
- Abnormal flexion (3)
- Abnormal extension (2)
- No response (1)
Reflex Arc
- Pain receptors in the skin detect heat and send signals through:
- Afferent neurons to the spinal cord
- Interneurons connect to efferent neurons
- Efferent neurons cause muscle contraction to withdraw from harm
- Afferent neurons transmit impulses toward the central nervous system (CNS)
- Efferent neurons transmit impulses away from the CNS
- The withdrawal reflex is a protective involuntary response.
Cranial Nerves
- Cranial nerves originate from the brain stem, carrying information to and from the body.
- Key functions of cranial nerves include:
- Olfactory: Smell
- Optic: Visual acuity
- Oculomotor: Eye movement and pupil dilation
- Trochlear: Vertical eye movement
- Trigeminal: Facial sensation and expression
- Abducens: Lateral eye movement
- Facial: Taste and facial expression
- Auditory: Hearing and balance
- Glossopharyngeal: Taste and swallowing
- Vagus: Throat sensation and visceral muscle function
- Accessory: Head and shoulder movement
- Hypoglossal: Tongue movement
Spotting a Stroke - BEFAST
- Balance loss: Difficulty maintaining stability
- Eyesight changes: Blurred or altered vision
- Face drooping: Asymmetry or weakness in facial muscles
- Arm weakness: Inability to raise both arms equally
- Speech difficulty: Slurred or incomprehensible speech
- Time to call 911: Immediate action required for potential stroke
Autonomic Nervous System
Parasympathetic Division
- Functions include:
- Pupils constrict
- Heart rate slows
- Digestion stimulates
- Bladder constricts
Sympathetic Division
- Functions include:
- Pupils dilate
- Heart rate increases
- Airways dilate
- Liver releases glucose
Differences Between Sympathetic and Parasympathetic
- Parasympathetic actions generally promote rest and digestion, while sympathetic actions prepare the body for 'fight or flight' responses.
Cranial Nerve Tests
- Tests include a variety of sensory and motor evaluations for each cranial nerve to assess neurological function.
- Common tests involve visual assessments (Snellen chart), facial expressions, and responses to sensory stimuli.
Brain Herniation Types
- Transcalvarial: Brain displacement through skull defects.
- Ascending transtentorial: Cerebellum compression and midbrain issues lead to coma.
- Tonsilar: Downward displacement causing respiratory issues.
- Subfalcine: Compression leading to behavioral changes and weakness.
- Central transtentorial: Progressive downward displacement results in severe symptoms including coma.
- Uncal transtentorial: Medial temporal lobe displacement causing various neurological symptoms.
