3 Characteristics of Anterior pituitary hormones
1. Protiens
2. Acts thru 2nd messenger systems
3. Regulated by hormonal stimuli, and in most cases, neg feedback
Growth Hormone (GH)
General metabolic hormone
plays important role in determining final body size, effects geared towards bones
hypersecretion of GH after long bone growth has ended
Pituitary Dwarfism
Hyposecretion of GH during childhood, max adult height 4 ft
hypersecretion of GH during childhood 8-9ft
Thyriod stimulating Hormone TSH aka Thyrotropic Hormone
influences growth and activity of thyroid gland ANTERIOR PIT
Adrenocorticotropic Hormone ACTH
Regulates the endocrine activity of the cortex portion of the adrenal gland ANTERIOR PIT
Gonadotropins FSH, LH, ICSH
Regulates Ovaries and testies hormonal activity ANTERIOR PIT
Prolactin PRL
Protien hormone target tissue is breasts. After child birth it stimulates and maintains milk production in mother ANT PIT
Thyroid stim hormone TSH, Adrenocorticotropic hormone ACTH, Gonadotropins FSH LH ICSH, Prolactin PRL
Antidiuretic Hormone ADH
AKA Vasopressin Inhibits or prevents urine production, causes kidneys to reabsorb more H2O from the forming urine
Diabetes Insipidus
Hyposecretion of ADH leads to this condition of excessive urine output
s/s: thirst, drink excessively
Thyroxine T4 and Triiodothyronine T3
T4 is major hormone secreted by thyroid, both control rate of which glucose is burned and converted to heat and enerty *Made of IODINE
Myxedema aka Hypothyroidism
Physical and mentally sluggish, Puffy face, fatigue, poor muscle tone, lower body temp, cold, obesity, dry skin
Hyposecretion of thyroxine, lack of stimulation by TSH, results in Dwarfism
Graves Disease
One form of hyperthyroidism, usually result of tumor in thyriod
Thyrocalcitionin (Calcitonin)
lowers blood calcium levels by causing Calcium to be deposited in the bone
PTH parathyriod Hormone
most important regulator of Calcium Ions homeostasis in blood, stim bone to break down, and release Ca into bl.
Hypoparathyriodism vs Hyperparathyroidism
Hyper- Bone destruction
Hypo- Neurons become irritable and overactive, Tetney occurs
ALDOSTERONE, produced in adrenal cortex, important in NA+ content in the blood, target cells is kidney tubules
Atrial Natriuretic Peptide
prevents aldosterone release, gooal being to reduse blood vol and blood pressure
result of tumors, hyperactivity of adrenal cortex, excessive H2O and NA are retained leading to high BP and edema
Adrenal cortex produces, Helps body resist long term sterssors, Rases BGM
Addisons Disease
major s/s bronze tone of skin. because aldosterone levels are low NA and H2O are lost
Cushings syndrome
excessive output of glucocorticiods, results in moon face, buffalo hump etc
AKA Adrenaline, fight or flight, made by ADRENAL MEDULLA, Catecholamine
AKA noradrenaline, rest or digest, made by ADRENAL MEDULLA, Catecholamine
Adrenal Medulla
The central part of the gland, secretes catecholamines, epinephrine and norepi when stim by sympathetic and parasympathetic nervous sys
Adrenal Cortex
the outer part of the gland, secretes mineral corticoids, glucocorticoids and androgens
Produced in Pancreas islets in Beta cells, antag of Glucagon
produced by the Graafian follicles of ovaries
Pineal gland
small cone shaped gland found in the roof of the third vent of the brain, chem substances have been ID'd here
located upper thorax, posterior to sternum, Decreases in size with age, produces hormone called thymosin, acts as incubator for T cells
HCG Human chorionic gonadotropin
Produced by embryo and then by fetal part of placenta
A neuron who's primary function is to connect other neurons
an association neuron
Reticular Formation
The brain area located in the cerebral cortex controlling the state of wakefulness or alertness
Spinal reflex goes along what reflex arc?
Receptor, afferent neuron, internuncial neuron, efferent neuron, effector
Main function of the rods in the eye
vision in the dim light
Receptors for hearing
Information is carried within a neuron ...
Dendrite-Cell Body- Axon
