Presentation Transcript

Neurons hormones behavior
Neurons + Hormones  Behavior

  • Releasing sites inside the central nervous system

    • Hypothalamus

    • neurotransmitters, neuropeptides

  • Neurosecretory factors released into bloodstream

    • Pituitary gland

    • neurosecretory factors

  • Target sites outside the central nervous system

    • Major organs

    • hormones


Neurons and hpo axis hypothalamic pituitary organ
Neurons and HPO Axis(hypothalamic-pituitary-organ)







Neurosecretory factors
Neurosecretory Factors

  • Two types

    • short route: signal originates in posterior pituitary (eg. oxytocin, vasopressin)

    • long route: signaling originates in hypothalamus, synapses in anterior pituitary (eg. everything else)


Long route
Long Route

Hypothalamus  Median Eminence  Hypophyseal Portal  Pituitary






Hormones
Hormones

  • Two types

    • Steroidal: binding sites in cell nucleus

    • Non-steroidal:binding sites on cell surface




Steroids alter b rain s tructure and behavior
Steroids alter brain structure and behavior
