Mental Health-the brain

  1. Serotonin
    - Originate in the midbrain and extends into all brain regions, particularly the hypothalamus

    - Also present in the blood Platelets and the lining of the digestive tract

    - Regulates state of consciousness, mood, depression, and anxiety. It affects basic bodily functions such as appetite, sleep,and sexual behavior.

    - May contribute to aggression and schizophrenia.
  2. Dopamine
    Is present in the three nerve tracts that have different functions
  3. Norepinephrine
    • - Transmitter located in the sympathetic nerves of the peripheral and central nervous systems.
    • -Is secreted by the adrenal glands in response to stress or arousal
  4. Psychotropic drugs are attributed to?
    • 1. Acetylcholine - not on test
    • 2. norepinephrine
    • 3. Dopamine
    • 4. Serotonin
    • 5. Gamma (Gabba)
  5. Occipital lobes
    In charge of processing visual input
  6. Parietal lobes
    Receives sensory information from the body
  7. Temporal lobes
    • Affects gross motor skills and the integration of sensory input
    • ex:hearing,perception,and storage of memory
  8. Frontal Lobes
    • -Largest,govern personality, emotion,reasoning,learning, and speech.
    • -Motor control
    • -Decision making and purposeful behavior
  9. Cerebal Cortex
    - Surface of each hemisphere is an intricately folded layer of nerve cells.
  10. Cerebellum
    • Behind the brain stem and receives information from the muscles, joints, balance, skin, the eyes, and ears
    • - Controls bodily functions operating below the level of consciousness. ex: posture,balance, movement through space
    • -memory of certain kinds of simple learned responses may be stored
  11. Reticular formation
    • At the center of the brain stem and traveling it's full length is a core of neutral tissue
    • - controls the position and tension of muscles
  12. Pons
    • -Hind brain
    • -located just under the midbrain
    • -links the various areas of the brain with each other and the central nervous systems
  13. Cerebellum/brain stem
    • - controls coordinated movements
    • -involved in language and thinking
    • -links the brain to the spinal cord
    • -maintence of the unconscious life support functions
    • - Medulla oblongata
    •    -regulates vital functions - arousal, heartbeat,respiration, blood flow, muscle tone, movement of stomach, and intestines.
  14. 3 sections of the brain
    • - Hind brain
    • -Mid brain
    • -Fore Brain
  15. Pathway
    A serious of interconnecting neurons working together for some coordinated purpose
  16. Psychopharmacology
    -The study of drugs that affect a person's thinking, emotions, and behaviors
  17. Basal Ganglia
    • - Connects the cerebral cortex and the other parts of the brain.
    • When unintentionally affected by certain psychotropic medications adverse side effects happen 
    •   ex:parkinson's
  18. Thalamus
    • -Located near the center of the Forebrain
    • -relays sensory information from the body to the brain
    • -Helps initiate consciousness and make preliminary classifications of external information
  19. Hippocampus
    • - involved in learning
    • -memory - helps convert information short term to long memory
    • -emotions
  20. Amygdala
    • - involved in memory
    • -emotional responses
    • aggression
  21. Thalamus
    • - switching station for sensory information
    • -involved in memory
  22. Neurohormones
    • - produced by the hypothalamus
    • -influence motivation, sexual arousal, eating and drinking, sleeping, waking, certain chemical balances, and emotions important to survival.
  23. Consists of brain stem, cerebellum, and pons
  24. Forebrain
    • Largest section of the brain
    • Consists of many specialized areas
  25. Limbic System
    • - involved in emotion and homeostasis
    • -regulates body temperature, blood pressure, heart rate, and blood sugar levels.
  26. Hypothalamus
    • - limbic system
    • - relay station for internal regulatory systems
    • -monitoring information coming from the autonomic nervous systems
    • - influencing the body's behavior through pathway
    • -produces neurohormones
  27. Midbrain
    • - monitors and integrates various sensory functions
    • - serves as a center of visual and auditory stimulation
    • -on the upper surface of the midbrain, collections of cells relay specific information from sense organs to higher levels of the brain.
  28. Postsynaptic membrane
    • Is a membrane of the cell body, or dendrite, on which receptor sites are located
    • - the receiving area of the synapse on the dendrite of the nerby cell body.
  29. Presynaptic terminal
    - an axon nerve cell ending containing neurotransmitters that extend to the synopse
  30. Cell Body
    • - central area of the neuron
    • -metabolic center
    • -lipid (fatty) material, the cell membrane separates the contents of the cell from the fluid enveloping it.
  31. Binding
    • - Process by which a neurotransmitter crosses the snypatic cleft and attached to a receptor in the postsynaptic membrane which activates chemical changes in the postsynaptic membrane
    • - can encourage or discourage the production of nerve impulses
  32. How do drugs work?
    • - by modifying natural events in the synapses along pathways in certain areas of the brain
    •  1. altering presynaptic activity to prompt neurotransmitter release
    • 2.altering post synaptic activity to affect receptor binding
    • 3.interfering with normal reuptake process
    • 4.altering the manufacture of receptors
  33. Reuptake
    -After transmission is complete the neurotransmitter is either discarded as waste by the grial cells or enters the presynpatic terminal for storage and use at another time
