Moment 2 Flashcards
head lies near duodenum
pancreas
pancreas made up of___tissue
exocrine and endocrine tissue
exocrine tissue in pancreas secretes
digestive enzymes
main pancreatic duct connects
common bile duct near duodenum
endocrine tissue in pancreas secretes (think endocrine)
hormones (such as insulin) into blood
blood supply to pancreas from…(blood GSS in pancakes)
splenic artery, gastroduodenal artery and superior mesenteric artery
pancreas assists in digestion by..
secreting enzymes that break down food, mostly fats and proteins
zymogens in pancreas (gems in pancakes) AND become active when they enter…
produced by exocrine cells and converted to active version - lipase and amylase - when they enter the small intestine.
secretes large amounts of sodium bicarbonate
pancreas - to neutralize stomach acid that reaches small intestine
exocrine functions in pancreas controlled by…(not ans)
hormones released by stomach and small intestine (duodenum) when food is present.
most nutrients are absorbed in the..
small intestine. enzymes come from pancreas, liver, and stomach.
bile is secreted from the..
liver
bile is stored in the…
gall bladder
bile is useful for breaking down…
fats
small intestine lining is covered with…
villi and microvilli, which increases surface area for interaction with chyme.
main absorption organ of the digestive tract
small intestine
large intestine also called the
colon
large intestine functions - (cement)
concentrates, mixes, and stores waste material. attaches to rectum
3 general types of neurons (MIS neurons)
sensory, motor and interneurons
sensory neurons transmit signals to the…
CNS from touch, pain, temp, smell, hearing, sight and taste
motor neurons
transmit signals from CNS to rest of body by signaling muscles
interneurons transmit signals….
between neurons.
dendrites transmit signals towards…
the cell body, received from sensory receptors and interneurons
axon transmits impulses…
away from the cell body
axon is insulated by
oligodendrocytes and myelin sheath, has nodes of ranvier. it terminates at the synapse
brain consists of (HMF)
hindbrain, midbrain and forebrain
hindbrain parts (CMP in the hind)
medulla oblongata, cerebellum and pons
midbrain does what? (meet in the middle)
integrates sensory signals and responses
forebrain (for THC)
cerebrum, thalamus, hypothalamus
cerebral cortex
thin gray matter covering cerebrum
4 lobes in brain
frontal, parietal, occipital and temporal
frontal lobe functions
short term and working memory, decision making, planning, judgement
parietal lobe
sensory input and spatial positioning of body
occipital lobe
visual input, processing and output
temporal lobe
auditory input and output
cerebellum - type of memory (belly implies)
implicit memories. damage to cerebellum - don’t blink when air blown in eye. Also balance.
posterior area of brain is called…
brain stem
3 parts of brain stem (pmm rose stem)
midbrain, pons and medulla oblongata
brain stem important for..(crud stem - CRD)
respiration, digestive and circulatory functions
midbrain (TTT chub middle)
tectum, tegmentum, and ventral tegmentum.
midbrain important for..(midway btwn sight and hearing)
helps relay info. regarding vision and hearing
information sent from cerebrum to…(cpm c)
pons, then medulla and cerebellum
medulla oblongata connects…(obvious)
connects spinal cord to brain
medulla oblongata important for..(2 systems)
circulatory and respiratory system
peripheral nervous system - parts
sympathetic and parasympathetic
autonomic nervous system maintains..(balance)
homeostasis
ANS controls___(BOGS) through the direction of the____
internal organs, blood vessels, smooth muscle tissue, and glands, though the direction of the hypothalamus
ANS is controlled by the..
hypothalamus
ANS maintains homeostasis of…(HBBB)
heart rate, breathing rate, body temp, and blood ph, digestion and breathing
somatic nervous system
controls 5 senses and voluntary movement of skeletal muscle
efferent nerves bring signals from… (somatic)
CNS to sensory organs and muscles
afferent nerves bring signals from…(somatic) (opposite of away)
sensory organs and muscles to the CNS
reflexes are___of the___system
involuntary movements of the CNS
reflex arc bypasses the…
brain and is controlled by spinal cord, I.e. knee jerk
3 types of muscle tissue (SCS)
skeletal, cardiac and smooth
3 properties of muscles - EEC
excitability, contraction, and elongation
skeletal muscle is….
striated, made up of muscle fiber bound together in bundles
smooth muscle is…
involuntary, non-striated, shorter and wider than skeletal muscle.
muscle fiber contain bundles called___composed of____
myofibril, composed of repeating units called sarcomeres.
myofibrils contain which filaments?
2 protein microfilaments - thick and thin filaments
thick filament is composed of…(my thick hair)
myosin
thin filament is composed of…(act thin)
actin
action potential - muscle
Ca is released and binds to myosin and actin, myosin head of thick binds to actin of thin, and adenosine triphosphate released from glucose, contraction occurs.
testes are the…
male gonads
epididymis (didy)
stores sperm as it matures
seminal vesicles secrete…(seminary alchy)
alkaline fluid into ejaculatory duct
prostate gland secretes…(pro-state)
white fluid as part of semen
bulbourethral (cowpers - male) (bulb)
secretes fluid into urethra to neutralize acidity
FSH in men stimulates…(fish)
spermatogenesis
luteinizing hormone in males stimulates…(test loot)
testosterone production
