structure and systems Flashcards
whats pseudopodia
It is when the mouth like peaks of when a cell eats something
what does gastrin do
it stimulates parietal cells ( release gastric juice) and pepsinogen (turns into pepsin to breakdown protein)
what secretes gastrin
g cells
what do cheifcells release
pesinogen and lipase
what is secretin? What stimulates the release of it?
it causes the release of bicarb in the stomach, is secreted when food enters duodenum
what do g cells secrete
gastrin
whats grehlin
increases hunger comes from stomach
whats saltory conduction
it AP jump from gap to gap on a neuron
where are crypts and what do they do
they release enzymes an make new enzyme, they are grooves located in intestines
3 parts of the small intestines
DJilleam
- duodenum
- jejunem
- illeam
what are kupffer cells
macrofages in the liver
what are oligodendrocytes
part of the central nervous system sheath
what stimulates gall bladder to release bile
cck
what stimulates the pancreas to secrete bicarb
secretin
whats leptin
released by fat to reduce hunger
what is epideymal cells
they are cells that cushion the CNS
what is a microglial cell
microphage cells around neurons
what is macroglial cells
- astrocytes (recycle nuerotrans)
- oligadendrocytes
- schwan
- epideymal cells
what do parietal cells do
they cause the secreation of gastric juices
what is the parietal lobe 4
for sensation
what are the layers of menengies
duramatter
pia matter
arachniod
what is the temporal lobe 4
for speach
what relays motor and sensory signals (part of the brain)
thalamus
what is the temporal lobe 4
for speech
what is IgD
nobody knows
what is IgA
found in breast milk
MHC 1 vs MHC 2
mhc everyone has MHC II are on antigent presenting cells
whats syntharthrosis
immovable joints
what cell releases histamines (WBC)
basophyl cells
whats langerhan cell and what does it do? what layer of skin is it found in
for immunity it is part of the spinosum
what gland is present everywhere but hands and feet
sebaceous
what layer of skin has hair follicle
dermis
what are lemallar bodies and what do they do
they make a water barrier in skin ( layer in granulosum)
hyaline vs fibrous cartilage
hyaline is support and fibrous is for cushion
synarthrosis what type of tissue is it made of
fibrous
mnomic for wbc
come lets get sun burt ( get some beer)
what layer of skin are merkel cells? langerhan? melanocytes?
merkel cells &melano cytes are in basale langerhan is in spinosum
whats lucanae
the space in between. the lamella
osteocytes live in the
lucanea
what summation causes tetanus
wave or temporal
what defines a motor unit
a single neuron attatching to multiple muscle fibers
the endomysium covers
sarcolema
what do cd8 and cd4 secrete
cd8 secrete porforine and granzyme cd4 secretes interluekin
IgG is for
oppsonization (tag for eating)
IgM is for
first antibody for compliment
CD4 have (MHC 1 or 2? what about cd4?
CD4MHC 2 and CD8 MHC1
BCR receptors attatch to
antigen
whats opsonization
tagging for eating
whats interpherons
released by sick cells
antigen presenting cells use what kind of receptor
TLR
whats a dendritic cell
its a antigen presenting cell
whas cceruminous
ear wax
whats diarthrosis
synovial joints
whats osteone
lammallea and haverson canal
whats canaliculi
small passage between haverson and lacunae
whats sesamoid bone
bone in tendon that helps mull muscle
what is the I band A band H zone M line
I band ( z disc thin filament) A band (Thick and thin) H zone (thick finalments and m line) M line (middle of thick filaments)
whats Ig E
allergies
whats mac
membrane attack complex —- poke hole in pathogen
what covers perimysium
fascle
what layer of skin has malanocytes
basale
what layer of skin has merkel cells and what the fuck are they
for touch in the basale
how do NK cells kill and how do granzymes killl
NK > with porforin
granzymes> with a apoptosis
what layer holds lammella bodies and what do they do
they make a water barrier and found in the granulosum
what antibody is for breast milk
IgA
what is amparthrosis & what kind of tissue is it made of
semi moveable cartilage
what is lamalla
layers of osteon
What does rhe pancreas release?
Bicarb, amylase, lipase, proteolytic enzymes ( trypsinogen, chynotripsinogen)
What does glutamate do
Excite central nervous system
What does dopamine do

Whats does the ossicle do
Transmit sound from air to cochlea fluid
What does the cochlea do
It interprets sounds
What does the organ of corti do
Interpret sounds
What does the thalamus do
It relays info from senses to cerebral cortex
