Study Notes

Brain Lateralization

  • Brain lateralization refers to the division of responsibilities between the left and right hemispheres of the brain.
  • The left hemisphere is dominant for logic, language, and mathematical skills.
  • The right hemisphere is associated with creativity, intuition, and musical abilities.
  • Communication between hemispheres occurs primarily through the corpus callosum.

Cerebral Cortex and Lobes

  • The cerebrum's outer layer, the cerebral cortex, consists of gray matter and is responsible for higher functions such as emotions, memory, and consciousness.
  • The frontal lobe is located at the front of the brain and handles concentration, memory storage, abstract thought, and motor functions.
  • Broca's area, within the frontal lobe, is crucial for language and motor control of speech.

Peripheral and Cranial Nerves

  • Peripheral nerves can be sensory, transmitting impulses to the brain, or motor, conducting signals from the brain to initiate movement.
  • Cranial nerves are directly connected to the brain, facilitating motor and sensory functions in the head and neck.
  • There are 12 cranial nerves, each with specific sensory or motor functions, such as the olfactory nerve (smell) and the vagus nerve (homeostatic functions).

Autonomic Nervous System

  • The autonomic nervous system regulates involuntary body functions essential for homeostasis, including respiration, digestion, and heart rate.
  • It comprises two main divisions: the sympathetic nervous system (activates "fight or flight" response) and the parasympathetic nervous system (promotes rest and digestion).
  • Regulation of the autonomic nervous system occurs in the hypothalamus, brain stem, and spinal cord.

Physical Effects of Neurological Impairments

  • Neurological impairments can lead to dizziness, balance issues, dysphagia, muscle weakness, paralysis, and loss of senses.
  • Activities of Daily Living (ADLs) may become difficult, significantly impacting independence.
  • Sensory impairments can endanger safety (e.g., poor vision or hearing).
  • Autonomic dysfunction can cause issues like orthostatic hypotension, resulting in light-headedness when changing positions.

Safe Patient Environments

  • Nurses should create environments that support patient independence with ADLs, particularly for those with neurological impairments.
  • For patients experiencing dizziness or balance issues, careful position changes are essential to avoid falls.
  • Understanding medication side effects, such as those from Lasix leading to orthostatic hypotension, can help manage symptoms effectively.
