The Endocrine System Unit 2 Lesson 6

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

Control Center Hypothalamus  In Forebrain  Regulates pituitary gland

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
