The flashcards below were created by user phantomr254 on FreezingBlue Flashcards. What would you like to do?


  1. Prosencephalon first layer
    • Telencephalon
    • Diencephalon
  2. Prosencephalon second layer
    • Cerebrum
    • Diencephalon
  3. Rhombencephalon first layer
    • Metencephalon
    • Myelencephalon
  4. Rhombencephalon second layer
    • cerebellum and pons
    • Medulla oblongata
  5. Cerebrum
    controls conscience sensations, intellect, memory, complex movement
  6. Cerebellum
    coordinates movement
  7. Diencephalon
    contains centers for emotions, autonomic functions, and hormone production
  8. Mesencephalon
    process visual and auditory sensory information
  9. Pons
    connects cerebellum to the brain stem and controls involved with somatic and visceral motor control
  10. Medulla Oblongata
    • Relays sensory information to the thalamus
    • autonomic functions of heart rate, blood pressure, and digestion
  11. Cranial meninges
    • 1. Dura mater
    • 2. Arachnoid
    • 3.┬áPia
  12. Cerebrospinal fluid
    cushions delicate structures, support the brain, transports nutrients, chemicals and wastes
  13. Epidural hemorrhages
    • are the most serous and fatal if not treated quickly
    • due to arterial bleeding which has vary high pressure causing severe distortion of tissues
  14. Subdural hemorrhages
    causes are from venous bleeding which has much lower pressure
  15. blood brain barrier exceptions
    • 1. portions of the hypothalamous (control hormones)
    • 2. Capillaries in pineal gland (hormone regulation)
    • 3. Capillaries of the posterior pituitary gland (hormones)
    • 4. capillaries of the choroids plexus (cell produce CSF)
  16. Gyri
    elevated ridges
  17. Sulci
    shallow depressions
  18. hemisphere of cerebrum
    • 1. central sulcus
    • 2. Lateral sulcus
    • 3. Parieto-occipital sulcus
  19. 3 key aspects to all hemisphere
    • 1) each cerebral hemisphere receives sensory info. and sends motor commands to the opposite side of the body
    • 2) Each hemisphere has a different function
    • 3) Assignment of specific function is imprecise
  20. Central white matter composed of major groups of axons
    • 1) associated fibers
    • 2) Commissural fibers
    • 3) Projection fibers
  21. somatosensory Association area
    monitors activity in the primary sensory cortex
  22. General interpretive area
    receives and analyzes sensory info
  23. Aphasia
    where an individual cannot talk or understand the language
  24. Speech center
    Regulates patterns of breathing and vocalization
  25. Prefrontal cortex
    preforms abstract functions such as predicting consequents of behavior, events or actions
  26. Cerebral nuclei
    Direct many subconscious activities
  27. limbic system
    establishing emotional states and related behavior drives
  28. Thalamus
    Filter sensory info
  29. Hypothalamus
    • 1. subconscious control of muscle contractions
    • 2. Control of autonomic function
    • 3. Coordinates activity of the nervous and endocrine system
    • 4. Secretes hormones
    • 5. Produces emotions and behavior drives
    • 6. coordinates voluntary and autonomic function
    • 7. regulates body temperature
  30. Techum
    Integrates visual info with other sensory imputes involuntary mote responses
  31. Inferior colliculi
    relay auditory info to the thalamus
  32. red nuclei
    involuntary control of tone and posture
  33. substantia nigra
    regulates activity of cerebral nuclei
  34. reticular formations
    Autonomic processing of incoming sensations and outgoing motor commands, maintains conscience
  35. Cerebral peduncles
    connects primary motor cortex with motor neurons in the brain and spinal cord
  36. 12 cranial nerves, function, and labeling
    You can do it!!!!
