Flashcards in A&P - 2 Deck (31):
1

Auditory Assoc Area

Temporal lobe

2

Wernicke's Area

L temp lobe & parietal lobes

3

Prefrontal Cortex

Ant portion of the Frontal Lobe

4

CN I

Olfactory
Sensory
Smell

5

Optic
Sensory
Vision

6

Vestibular: equilibrium
Cochlear: Hearing

12

CN IX

Glossopharyngeal
Both
S: taste + sensation POST 1/3 TONGUE
M: elevates phalanx during speech
A: stims saliva secretion

13

Accessory
Motor
Mvmt of head + pectoral girdle (traps, rot cuff, etc.)

15

CN XII

HYpoglossal
Motor
Mvmt of tongue during speech + swallowing

16

Contractile mm fibre proteins

"Generate force during mm contractions"

-Myosin: thick filament, binds to actin molecules of the thin filament during contract

- Actin: thin filament, myosin binding site on each - binds during mm contraction

17

Regulatory mm fibre proteins

"Helps switch mm contraction processes on/off"

-Tropomyosin: thin filament, when mm is relaxed, it covers myosin binding sites on actin molecules preventing from binding

- Troponin: Think filament, Ca+ binds to Troponin = changes shape = moves Tropomyosin away from binding sites on actin = mm contraction begin

18

Structure mm fibre proteins

"Elasticity/extensibility"
Titin
@ actin
My onesie
Neburin
Dystrophin

19

Ant pituitary Hormones

HGH--> liver - stims insulin growth factor + growth of body
TSH--> thyroid - stims synth + secretion of Thyroid hormones
FSH--> ovaries/testies - oocytes/sperm production
LH--> " /" - estrogen + progesterone + Luteum formation/ testosterone in males
Prolactin--> mammary glands
ACTH--> Adrenals - stims cortisol secretion
MSH --> Brain

20

Post Pituitary Hormones

Oxytocin--> mammary + uterus

ADH / vasopressin-->Kidneys - conserves. H2O in body
(Also affects sweat glands, arterioles)

21

Thyroid Gland Hormones

T3 + T4 from Follicular cells--> stims release of TSH from Ant pituitary - increases basal metabolic rate

Calcitonin from parafollicular cells--> high blood Ca+ levels stim secretion - lower blood Ca+ levels by stim Osteoblasts

22

Parathyroid hormone

PTH from Cheif cells - low blood Ca+ stim secretion - increase osteoclasts activity (resorption)

23

Adrenal Hormons

Aldosterone-->increases blood K+ & angiotensin II stim - increase blood Na+/H2O

Cortisol--> stims gluconeogenesis + Lypolysis - stress resist

Epinephrine / NOepinephrine -->symp pre gg relapse ACh - stims secretion- enhances ANS surfing stress

24

Pancreatic Islet Hormones

Glucagon via alpha cells-->raise blood glucose via converting stored glycogen into glucose in liver

Insulin--> lower blood glucose levels by accelerating glucose into cell to be used for ATP. Increase lipogenesis also

25

Hormones of ovaries & testies

Ovaries
Estrogen / progesterone: (ant pit)
Relaxin
Inhibin: inhibits FSH from ant pit

Testies
Testosterone: spermatogenesis & develop sex organs
Inhibin

26

Pineal Gland Hormone

Melatonin = sleep

27

GI tract hormones

Gastrin-->gastric so juice + digestive mvmts
Secretin--> panc juices + bile
GIP--> stims insulin release
Cholecystokinin --> reg bile from gallbladder, fullness feeling

28

Hormones of Kidneys

Renin-->raises BP via vasoconstriction + secrete Aldosterone

EPO-->increase RBC formation

Calcitriol--> increase absorption of Ca+ from GI tract

29

Hormone of Heart

ANP--> decrease BP

30

Hormone of Adipose tissue

Leptin--> suppresses apetite

31

Stages of Wound Healing:

1 - Inflam phase: blood clot, Inflam, vascular response, macrophages, fibroblasts

2- Migratory Phase: scab, migration, scar tissue forms (via collagen), BVs regrow, GRANULATION

3- Proliferation: deposition of collagen/fibroblasts Radom order

4- Maturation: scab sloughs off, BVs restored, tissue become more organized
