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
