Show Answers:

  1. cerebral spinal fluid
    preforms a liquid cushion that gives bouancy to the brain, protects and nourishes the CNS. made in the choricoid plexus
  2. blood brain barrior
    regulates the substances that can enter the interstical fluids of the brain.
  3. ganglion
    cluster of neuron bodies within the PNS
  4. center
    group of CNS neuron cell bodies with a common function.
  5. nucleus
    center that displays discrete autonomic boundries
  6. nerve
    axon bundle extending through the PNS
  7. Nerve plexus
    network of nerves
  8. tract
    CNS axon bundle in which the axons have a similar function and share a common origin and destination.
  9. funiculus
    groups of tracts in a specific area in the spinal cord
  10. pathway
    centers and tracts that connects the CNS with the body organs and systems.
  11. meninges
    it fuctions to cover and protect the CNS. protect the blood vessels and enclose venous sinuses, has a cushioning of CSF called the arachnoid. The brain has pia mater and covering that is the dura mater.
  12. frontal lobe
    involved in voluntary motor function, concentration, verbal communication, decision making, planning and personality.
  13. parietal lobe
    involved with general sensory functions.
  14. temporal lobes
    involved with hearing and smell.
  15. occipital lobe
    processes incoming visual information and stores visual memories.
  16. insula
    involved in memory and interpretation of taste.
  17. precentral gyrus
    primary motor cortex for muscle memorie stuff
  18. post central gyrus
    primary sensory cortex
  19. cortex
    • made out of grey matter(unmyelinated) is the outer part of the cerebrum function is for higher thinking
    • underneath is white matter myelinated has association tracts and areas. (tracts= CAP)
  20. diencephalon
    3 areas- epithalamus, epithalamus, hypothalamus
  21. thalamus
    blocks out all the white noise around you so that you can focus on what you want to listen too. so sensory wont get over loaded.
  22. epithalamus
    has the pineal body that creates the melatonin that starts the circadian rhythm; the habenular nuclei connects smells and visual cues with memories.
  23. hypothalamus
    controls the ANS, control of the endocrine system, regulates body temp., controls emotional behavior, control food and water intake, and it leads down the fundibulum to release the hormones to the pituitary gland to be released.
  24. brainstem
    • Pons- regulate the rate and depth of breathing.
    • medulla oblongata- cardiac center- regulates heart rate and strength of contraction.
    • vasomotor center
    • respiratory center- modifys the pons
  25. substantia nigra
    dark part that creates dopomine
  26. the cerebrellum
    • makes up 11% of the brains mass
    • provides precise time and appropriate patterns of skeletal muscle contraction or else the person is all jerky and cant get the spoon to the mouth.
  27. the nerves
    • OH- olfactory
    • ONCE- optic
    • ONE-oculomotor
    • TAKES-trochlear
    • THE- trigeminal
    • ANATOMY- abducens
    • FINAL- facial
    • VERY - vestibulocholear
    • GOOD- glossopharangeal
    • VACATIONS- vagus
    • ARE- accessory
    • HEAVENLY- hypoglossal
