Which Gland??
The gland that that contains your fight or flight response is the ...
What is Adrenal Medulla
What is down regulation?
the cell loses the ability to respond to receptors due to nutrient deficiency
release hormones
Name the structure, target tissue, and response of GHRH
Structure - peptide
Target Tissue - anterior pituitary cells that secrete growth hormone
Response - increased growth, hormone secretion
name the 5 senses
olfaction, gustation, vision, hearing/ equilibrium
The Adrenal Cortex layers
What is Zona Glomerulosa, Zona Fasciculata, Zona Reticularis?
What is up regulation?
Increase concentration of receptors due to a signal
Endocrine glands
secretes hormone into the blood stream
Name the structure, target tissue, and response of GHIH
Structure: small peptide
Target Tissue: anterior pituitary cells that secrete hormone growth
Response: decreased growth hormone secreation
vision accessory structures
eyelids, eyelashes, lacrimal glands
What are the parathyroid glands, and what do they do?
PTH, increases blood calcium, affects bones and kidneys,
What are the receptor mechanisms?
Membrane-bound receptors, intracellular receptors
Exocrine glands
secrets substances like sweat & digestive systems
Name the structure, target tissue, and response of TRH
structure: small peptide
target tissue: anterior pituitary cells that secrete thyroid stimulating hormone
response: increased thyroid hormone secretion
Hearing pathway
sound waves --> tympanic membrane --> ossicles --> oval window --> cochlea --> spiral organ --> cochlear nerve --> auditory cortex
What are the parts of the pituitary gland?
Hypothalamus regulation, anterior pituitary gland, and posterior pituitary gland
What are the hormone interactions?
Synergistic, Antagonistic, Permissive
Give me a run down of hormonal stimuli
Certain hormones are secreated in response to anotehr hormone
Name the structure, target tissue, and response of CRH
structure: peptide
target tissue: anterior pituitary cell
Response: increased adrenocortropic hormone secretion
taste bud structure
gustatory cells with microvilli, supporting cells, basal cells
Name all the hormones in the anterior pituitary gland
GH, TSH, ACTH, LH, FSH, PRL
What are the stimulatory influences on hormone secretion and what do they do?
Humoral - blood levels of ions and nutrients
Neural - nervous systems stimulation
Hormonal - one hormone regulates another
Neuropeptides
small chains if amino acids that are synthesized and released by neurons
Name the structure, target tissue, and response of GnRH
structure: small peptide
target tissue: secrete luteinizing hormone and follicle stimulating hormone
response: increased serotonin of luteinizing hormone
Action Potential stimulation
odorant molecules dissolve in mucus --> bind to receptors --> generate action potentials in the olfactory nerves
