  1. Gonads
    Sex glands that create hormones
  2. Somatic
    Part of the PNS, picks up messages from the nerves and relays the information to the brain via spinal cord
  3. Agonists
    Mimic neurotransmitters
  4. Antagonists
    Block or disallow reuptake of neurotransmitters
  5. Parkinson's Brains lack this, Schizophrenic patients' brains have excess
    Dopamine
  6. the minimum level of stimulation required to fire a neuron
    Threshold
  7. a pair of endocrine glands that sit just above the kidneys and secrete hormones that help arouse the body in times of stress
    Adrenal Glands
  8. 2 lima bean sized neural clusters in the limbic system; linked to emotion
    amygdala
  9. the part of the peripheral nervous system that controls the glands and the muscles of the internal organ. Its sympathetic division arouses, its parasympathetic division calms.
    Autonomic Nervous System
  10. the neuron extension that passes messages through its branches to other neurons or to muscles or glands
    axon
  11. Brain and Spinal Cord
    Central Nervous System (CNS)
  12. The little brain at the rear of the brainstem. Processes sensory input
    Cerebellum
  13. the large band of neural fibers connecting the 2 brain hemispheres and carrying messages between them
    Corpus Collsum
  14. a neurons bush, branching extensions that receive messages and conduct impulses towar the cell body.
    Dendrite
  15. The bodys slow chemical communication system; a set of glands that secrete hormones in the blood stream
    Endocrine
  16. Chemical messengers that are manufactured by the endocrine glands. They travel through th blood stream and affect our tissues
    Hormones
  17. a neural structure lying below the thalamus; it directs sever maintenance activities, helps govern the enodcrine system via the pituitary gland, the end is linked to emotion and reward
    hypothalamus
  18. an are at the rear of the frontal lobe that controls voluntary movements
    motor cortex
  19. a fatty tissue layer segmentally enclosing the axons some neurons. It speeds up the transmission of a neural impulse.
    Myelin SHeath
  20. a nerve cell, basic building blocks of the nervous system
    Neurons
  21. Division of ANS that calms the body, conserving energy
    Peripheral Nervous System (PNS)
  22. the endocrine systems most influential gland. Under the influence of the hypothalamus, regulates growth, and controls endocrine glands
    Pituitary
  23. Encompasses part of the visual cortex, coordinates difficult activities such as multi tasking or playing music?
    Angular Gyrus
  24. executes speech
    Broca's area
  25. chemical messengers that cross the synaptic gaps between neurons. When released by the sending neuron, they travel across the synapse and bind to receptor site on the receiving neuron, there by influencing whether that neuron will generate a neural impulses.
    neurotransmitter
  26. a nerve network that travels through the brainstem and plays an important role in controlling arousal.
    Reticular Formation
  27. area at the front of the parietal lobes that registers and processes body touch and movement sensations
    Sensory Cortex
  28. a 2 way information highway connecting between the peripheral nervous system and the brain
    Spinal Cord
  29. division of the autonomic nervous system that arouses the body, mobilizing its energy in stressful situation
    Sympathetic Nervous System
  30. meeting point between neurons
    synapse
  31. the brains sensory switchboard, located on top of the brainstem; it directs messages to the sensory receiving areas in the cortex, transmits replies to the cerebellum and medulla.
    Thalamus
  32. controls the bodys metabolism
    thyroid
  33. interoperates and makes sense of what you hear
    wernicke's area
  34. influences movement, learning, attention, and emotion. Lack of it is found in parkinsens, excess is found in schizophrenia
    Dopamine
  35. affects mood, hunger, sleep, and arousal, lack of leads to depression
    Serotonin
  36. enables muscle movement, learning and memory.
    Acetylcholine
  37. natural opiates, like neurotransmitters they are linked to pain control and pleasure
    Endorphins
  38. a neural impulse, a brief charge that travel down the axon
    Action Potential
  39. Part of the PNS that controls the glands and muscles of the internal organs
    Autonomic Nervous System
  40. form junctions with other cells
    axon terminals
  41. a neural center located in the limbic system; helps process explicit memories for storage
    hippocampus
  42. portion of the cerebral cortex lying at the back of the head; areas the receive information from the visual fields
    Occipital Lobe
  43. portion of the cerebral cortex lying at the top of the head and toward the rear; receives sensory input for touch and body input
    Parietal Lobe
  44. an organ of soft nervous tissue contained in the skull of vertebrates, functioning as the coordinating center of sensation and intellectual and nervous activity
    brain
  45. potion of the cerebral cortex lying roughly above the ears; includes the auditory areas, each receiving information primarily from the opposite ear
    temporal lobe
  46. modulates our speech, orchestrates our sensee of self, helps with perceptual tasks
    Right Hemisphere
  47. life support center
    soma cell body
  48. a fluid- or air-filled cavity or sac, in particular
    vesicle
