The flashcards below were created by user michaelirby98 on FreezingBlue Flashcards. What would you like to do?


  1. Cortex
    cortex superficial surface (grey
  2. Corpus callosum
    Connects the two hemispheres for communication (white)
  3. Gyri and sulci
    • Gyri: Ridges
    • Sulci: shallow groves
  4. 4 lobes of the brain
    • Frontal
    • Temporal
    • Parietal 
    • Occipital
  5. Frontal Lobe
    • Coordinates movements (skeletal muscle)
    • Reasoning
    • Emotion
  6. Temporal Lobe
    • Receives and monitors auditory stimuli
    • Memory
    • Speech
    • Primary motor
  7. Parietal Lobe
    • Receives and monitors general somatic sensory information (touch, pain, temp) 
    • Primary sensory cortex
  8. Occipital Lobe
    Receives and integrates visual information
  9. Cerebellum
    Automatic control of posture coordination of body movements
  10. Diencephalon
    • Links cerebral hemispheres to the rest of the CNS
    • Includes thalamus and hypothalamus
  11. Thalamus
    Relays and processes sensory information
  12. Hypothalamus
    Roles in emotion, regulating temp, H20 balance, metabolism, hormones, Day-Night cycles
  13. Brain stem
    • Midbrain: process visual information
    • Pons: Regulates breathing
    • Medulla Oblongata: Regulates heart rate blood pressure, breathing, swallowing, vomiting
  14. Right brain
    • Function: Movement and sensory perception for left side of body
    • Associated with creativity, music, spatial orientation, dream imagery, intuition
  15. Left Brain
    • Function: Movement and sensory information for the right side of the body
    • Associated with logic, analytical processing, language, math
  16. How sensory information converts
    Stimuli -> impulse -> brain
  17. What is perception
    Conscious interpretation of the external world
  18. Function of sensory receptors
    • Detect specific modalities from environment -> impulse 
    • Modality: different energy forms
    • (photons, chemicals, sound waves, pressure, temp)
  19. Law of specific nerve energies
    Each receptor is specific for a particular modality -> adequate stimulus modality that receptor responds best
  20. 4 classes of sensory receptors
    • Photoreceptors
    • Chemoreceptors 
    • Thermoreceptors
    • Mechanoreceptors
