Endocrine System
Endocrine System (ES) Endocrine System: set of glands that secrete hormones into the bloodstream • instrumental in regulating: • mood • growth and development • tissue function • metabolism • sexual function • reproductive processes • Snail mail (ES) vs. E-mail (NS) • Responsible for slower processes like cell growth
Endocrine Terms to Know • Glands: a group of cells that produces and secretes, or gives off, chemicals (hormones) – Exocrine glands – ex. Sweat/salivary excrete in a specific sites of the body – Other glands: send chemicals through bloodstream to other cells in the body • Hormones: chemical messengers that transfer information and instructions from one set of cells to another – move through the bloodstream – each type of hormone is designed to affect only certain cells – Can influence our interest in sex, food, and aggression – Some are chemically identical to neurotransmitters
Adrenal Gland • Adrenal Glands: secrete epinephrine (adrenaline) and norepinephrine (noradrenaline) to arouse body in times of stress – Located on top of each kidney • Two parts: – Adrenal Cortex: helps to conserve sodium in the body, increase blood glucose levels, regulate sex hormones such as estrogen – Inner Medulla: secretes epinephrine (aka adrenaline) and norepinephrine in times of stress
Pituitary Gland • Pituitary Gland: ES’s most influential gland; regulates growth and controls other ES glands – **under the influence of the hypothalamus – Growth Hormone Production – Production of Hormones That Act on the Muscles and the Kidneys – Endocrine Function Regulation – Storage of Hormones Produced by the Hypothalamus
Let’s jump over to the brain… Brain hormones pituitary other glands
Brainstem The Brain • the oldest part and central core of the brain, beginning where the spinal cord swells as it enters the skull • responsible for automatic survival functions (breathing, etc. )
The Brainstem § Medulla [muh-DUL-uh] § base of the brainstem § controls heartbeat and breathing § Pons § Connects different brain regions together § Involved in facial expressions
The Brainstem § Reticular Formation § a nerve network in the brainstem that plays an important role in controlling arousal § Thalamus [THAL-uh-muss] § the brain’s sensory switchboard, located on top of the brainstem § it directs messages to the sensory receiving areas in the cortex and transmits replies to the cerebellum and medulla
The Brainstem § Cerebellum [sehr-uh. BELL-um] § the “little brain” attached to the rear of the brainstem § it helps coordinate voluntary movement and balance § Formulates implicit memories
The Limbic System • a doughnut-shaped system of neural structures at the border of the brainstem and cerebral hemispheres • associated with emotions such as fear and aggression and drives such as those for food and sex • includes the hippocampus, amygdala, and hypothalamus.
The Limbic System
The Limbic System § Amygdala [ah-MIG-dah-la] § two almond-shaped neural clusters that are components of the limbic system and are linked to emotion (specifically aggression and fear)
The Limbic System § Hypothalamus § neural structure lying below (hypo) the thalamus; directs several maintenance activities § Eating and drinking § Sex drive § body temperature § helps govern the endocrine system via the pituitary gland
Hypothalamus Stimulation § Electrode implanted in reward center of hypothalamus § Rat readily crosses to get stimulation
The Limbic System • Hippocampus: a structure in the limbic system linked to explicit memory (Clive Wearing example) • Pituitary Gland: master endocrine gland, linked to growth
