Sensory
Vestibular: equilibrium
Cochlear: Hearing
CN IX
Glossopharyngeal Both S: taste + sensation POST 1/3 TONGUE M: elevates phalanx during speech A: stims saliva secretion

Motor
Mvmt of head + pectoral girdle (traps, rot cuff, etc.)
CN XII
HYpoglossal
Motor
Mvmt of tongue during speech + swallowing
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
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
Structure mm fibre proteins
"Elasticity/extensibility" Titin @ actin My onesie Neburin Dystrophin
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
Post Pituitary Hormones
Oxytocin–> mammary + uterus
ADH / vasopressin–>Kidneys - conserves. H2O in body
Also affects sweat glands, arterioles
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
Parathyroid hormone
PTH from Cheif cells - low blood Ca+ stim secretion - increase osteoclasts activity (resorption)
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
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
Hormones of ovaries & testies
Ovaries
Estrogen / progesterone: (ant pit)
Relaxin
Inhibin: inhibits FSH from ant pit
Testies
Testosterone: spermatogenesis & develop sex organs
Inhibin
Pineal Gland Hormone
Melatonin = sleep
GI tract hormones
Gastrin–>gastric so juice + digestive mvmts
Secretin–> panc juices + bile
GIP–> stims insulin release
Cholecystokinin –> reg bile from gallbladder, fullness feeling
Hormones of Kidneys
Renin–>raises BP via vasoconstriction + secrete Aldosterone
EPO–>increase RBC formation
Calcitriol–> increase absorption of Ca+ from GI tract
Hormone of Heart
ANP–> decrease BP
Hormone of Adipose tissue
Leptin–> suppresses apetite
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
