Transcript of The Endocrine System Unit 2 Lesson 6. Objectives Explain how glandular system can affect behavior....
Objectives
Explain how glandular system can affect behavior.
Distinguish between endocrine and exocrine.
Locate major endocrine structures.
Warm Up
Although we use behavioral animal studies (like ethology and sociobiology) to explain some human behaviors, what really separates us from lower animal species?
Review: Brain Damage/Disorders
Visual Cortex?
Cerebral Cortex?
Hypothalamus?
Auditory Cortex?
Cerebellum?
Medulla?
Concussion?
Stroke?
Epilepsy?
Alzheimers?
Meningitis?
Tourettes?
Sending Info To & From Brain
Nervous System EC signals,
neurotransmitters, from neuron to neuron
Rapid
Short-lived effects
Endocrine System Chemicals, hormones,
sent thru bloodstream
Slow
Long-lasting effects
Glandular System- Produce hormones
Exocrine System
Glands w/ ducts
Saliva, sweat, tears exit body through ducts
Endocrine System
Ductless glands
Hormones into bloodstream, travel to receptor sites w/in body
Major Glands
Pituitary Gland In brain “Master gland” Controls output of
hormones by other glands
Growth hormone Homeostasis
Pineal Gland In brain
Hormone = melatonin Sleep, SAD
Major Glands
Thyroid In neck Hormone = thyroxine Controls rate of
metabolism
Parathyroid In thyroid Control calcium levels in
blood
Major Glands
Adrenal Glands One on each kidney Hormone = Adrenaline
Oradrenaline
Reinforce SNS responses
Pancreas Above stomach Hormone = Insulin Regulates blood sugar
Major Glands
Gonads In lower abdomen Control reproduction
and secondary sex characteristics
Male: Testes Testosterone
Female: Ovaries Estrogen and
progesterone
