Cards

Term
Modified tyrosine:
Definition
T4
T3
Epinephrine
Term
cholesterol derivatives (steroids)
Definition
testosterone (testes)
estrogen (ovaries)
progesterone (ovaries)
aldosterone (adrenal cortex)
cortisol (adrenal cortex)
Vitamin D3 (Skin liver Kidney)
Term
Hypothalamic releasing hormones
Definition
GnRH = gonadotropin releasing hormone
CRH = corticotropin releasing hormone
TRH = thyroid hormone releasing hormone
GHRH = growth hormone releasing hormone
Term
Pituitary hormones:
Definition
Term
four hormone binding domains
Definition
Hormone-binding domain:the hormone binds near the carboxy terminus of the receptor

Nuclear binding domain: contains an amino acid sequence that targets the receptor to the nucleus.

DNA binding domain: allows the receptor to bind to the DNA

transactivation domain:alters the DNA structure to initiate transcription
Term
2nd messengers
and where are they involved?
do what?
Definition
CA concentration, cAMP production, IP3, DAG

g couple protein receptors

signal amplification
Term
hypothalamus
Definition
vasopressin (ADH) and oxytocin- neuron that extended into the posterior pituitary portion

Contains neurons that release hormone releasing factors
Term
Kinases
make up what? Which is a what?
Definition
Serine
threonine
tyrosine

Make up the receptors of a cell surface receptor for protein/peptides
Term
epinephrine comes from?
Definition
adrenal medulla
Term
Receptor signaling cascade/ all processes affected by cell surface receptors
Definition
protein transport
protein synthesis
secretion
ion channels
gene expression (Slow as shit)
Term
physiological changes in the cell
Definition
cell growth and differentiation
glucose metabolism
glucose transport
gene expression
Term
peptide hormone groups
Definition
All hypothalamic releasing hormones
All pituitary hormones
All GI hormones
All pancreatic hormones
Calcitonin
and Parathyroid hormon (PTH)
Term
benefits of cell surface receptors
Definition
instant physiological change/cascade

signal amplification (2nd messengers)
Term
3 parts of the hormone
Definition
pre- localizing signal

pro- protector

hormone- GnRH 10 amino acids
Term
adrenal medulla

adrenal cortex
Definition
epinephrine

Corticol
Aldosterone
Term
fatty acid process
Definition
1.stimulus activate across the membrane
2. activating the phospholipase
3. Arachonic
4. Cyclooxgenase
Term
cholesterol structure
Definition
27 carbons
Term
production of steroid hormones
Definition
1. cholesterol (27 carbons
2. side chain cleavage (mitochondria and rate limiting)
3. Pregnenolone (21 carobs)
4. Launching point for protein production
Term
controller
master gland
final target
Definition
hypothalamus

anterior pituitary (anterior only)

thyroid, gonads, adrenal, breast, liver
Term
anterior portion of the pituitary gland
Definition
gonadotrops
thyrotropes
somatotropes
corticotropes
lactotropes
Term
lactotropes
Definition
produces prolaction
affects lactation
negatively related to dopamine
Term
target tissue: CRH/corticotropes
Definition
adrenal cortex

Release of Cortisol
Term
three types of cartilage
Definition
hyaline- Lots of collagen

elastic- Elastin protein, ears

fibrocartilages- Rich in collogen, Between vertibrates, Meniscus of the knees
Term
Connective tissue proper: Types
Definition
Three Types
1. Tendons
2. Ligaments
3. Dermis of Skin
Term
Connective tissue proper: Uses what?
Definition
collagen
elastic
fimbrin
transmembrane protein
Term
Cartilage: extracellular matrix
Definition
collagen

elastin

GAG
Term
4 tissues
Definition
nerves
muscles
epithlium
connective tissue
Term
Layers of skin: epithilium
Definition
all made of keratinocytes

Stratum Basale: live close to basal lamina, Live cells, melanocytes, production of vitamin d

Stratum Spinosum: live/dead cells,

Stratum Granulosum: Dying cells, release glycolipids, waterproofing

Stratum Corneum: Dead Cells
Protection, hornea against bacteria
Term
melanocytes
Definition
Crossing with the basil lamina and basale
provide pigment,
protect from UV
prevents production of vitamin D
Term
junctions
Definition
Anchoring
tight/occluding
communicating/gap
Term
Epithelium characteristics
Definition
Form linings
At junctions
Attached to extracellular protein structure
Not vascularized
Cellular-> Continuous sheet of cells
Polarized -> Top (Apical) and bottom (basilar)
Regenerate
Term
anchoring junctions
Definition
uses keratin to hold onto the cytoplasm of the cells

Desmosomes: attaching to neighboring cells using cadherens (transmembrane proteins to hook)

Hemidesmosomes: used to anchor to the basil lamina. Uses intergrin.
Term
The functions of connective tissue are:
Definition
1 support (as in bone, ligaments, and tendons)
2 protection (as in bone, and cells of the immune system)
3 insulation (as in adipose tissue)
4 transportation (as in blood)
