Psychology6.3 The Limbic System and Endocrine System
• The Emotional Brain Structures lying deep within
the cerebral hemispheres.
Coordinates behaviors needed to satisfy motivational and emotional urges arising in the hypothalamus.
Also involved in memory
•Limbic SystemOverview
•Limbic SystemWhat does emotional brain mean?
Intense game + Friend/Phone Interrupting = yea……
The Endocrine System
• Consists of a group of glands that produce hormones
• Works with nervous system to control and coordinate all other body systems
• Effects body systems by chemical stimuli
Hormones
• Chemical messengers with regulatory effects on cells or organs
• Some affect many tissues• Growth hormone• Thyroid hormone• Insulin
• Some affect a specific tissue (target tissue)• Thyroid-stimulating hormone (TSH)• Adrenocorticotropic hormone (ACTH)
Other Hormone-ProducingTissues
Substances that regulate body actions are also produced by• Stomach• Small intestine• Kidneys• Brain• Atria of heart• Placenta

Thalamus:Relay Center for SensoryInformation
• Set of glands that regulate the flow or hormones into the bloodstream
• Relatively slow communication system• Interconnected with the nervous system• Pituitary, thyroid, parathyroid, adrenal glands, pancreas, ovaries, testes
•Endocrine System
•Endocrine SystemHypothalamu
sPituitary
Thyroid
Adrenal cortex
Adrenal medulla
Pancreas
Ovaries (female)
Testes (male)
•Endocrine
Hypothalamus:It controls body temperature, hunger, thirst,
fatigue, sleep and circadian cycles.
Controls the pituitary gland
•Endocrine
Pituitary • Regulates growth• Controls thyroid, ovaries or testes,
pancreas, and adrenal cortex• Regulates water and salt
metabolism• The “master gland”
•Endocrine
Thyroid Controls the metabolic rateThe function of this gland is to cause lymphocytes (white blood cells) to become T -cells -the cells which become part of the body’s defence against infection.
•Endocrine
Adrenal Regulates carbohydrate and salt metabolism
• Prepares the body for action• Secretes stress hormones
• The hormones produced by the adrenals prepare the body for stress. For example, the hormone epinephrine (or adrenaline) increases pulse rate and rate of breathing; also speeds up the conversion of food into energy.
•Endocrine
Pancreas• Controls levels of insulin and
glucagon• Regulates sugar metabolism• produce the hormones
glucagon and insulin. Insulin lowers blood sugar level while glucagon raises blood sugar level. So, the hormones in the pancreatic islets regulate the sugar level of the blood.
•Endocrine
Ovaries (female)Affect physical development, reproductive organs, and sexual behavior- Produce Estrogens- prepare for fertilized eggs.
•Endocrine
Testes (male)Affect physical development, reproductive organs, and sexual behavior-Produce Testosterone
