Excel in the Portage Learning Anatomy and Physiology final exam with this comprehensive study guide featuring questions and verified answers for 2026/2027. Master all essential A&P topics including neurophysiology (action potential all-or-none principle, frequency and neuron number determine intensity, sensory neurons, motor neurons, interneurons, afferent vs efferent, neurotransmitter synthesis and storage, acetylcholine release at neuromuscular junction, dopamine emotional responses and muscle tone, botulism flaccid paralysis mechanism), reflexes (stretch reflex muscle spindle, patellar tendon reflex pathway, flexor withdrawal reflex excitatory and inhibitory interneurons), nervous system organization (CNS vs PNS, ganglia, ventral root motor neurons, pia mater, astrocytes blood-brain barrier, axon regeneration in peripheral nerves Schwann cells, membrane potential resting -70mV, depolarization sodium gates, sodium-potassium pump), brain anatomy (cerebrum largest portion, ventricles produce CSF, hypothalamus functions except filtering sensory information, association areas, Broca's area speech production, cerebellum coordination, limbic system memory, brainstem, CVA hemorrhagic vs ischemic), cranial nerves (optic vision, oculomotor eye movement, trigeminal maxillary branch, facial anterior taste, vestibulocochlear hearing, glossopharyngeal posterior taste, vagus digestive sensation, spinal accessory shoulder movement, hypoglossal), spinal nerves (phrenic nerve ventilator, radial nerve wrist extension, sciatic posterior thigh sensation, lumbar plexus T12-L04), autonomic nervous system (sympathetic fight or flight, parasympathetic rest and digest, ciliary ganglion pupil reflex), special senses (eye layers sclera cornea, middle layer ciliary body iris, light pathway cornea lens vitreous retina, optic chiasm, lateral geniculate nucleus LGN visual fields, abducens lateral rectus, cataracts, ear external auricle meatus, middle ear ossicles tympanic membrane, inner ear cochlea semicircular canals, conductive deafness malleus injury, taste pathway circumvallate fungiform papillae gustatory cells facial glossopharyngeal nerves parietal lobe, agusia), cardiovascular system (pericardium anchors heart, mitral valve left atrium to ventricle, coronary arteries left anterior intraventricular, arteries stretch recoil, subclavian artery strong pulse, blood flow artery arteriole capillary venule vein, tunica media muscular layer, circle of Willis vertebral internal carotid basilar posterior cerebral, formed elements, osmotic pressure, coagulation cascade prothrombin thrombin, systemic circuit, SA node pacemaker right atrium, EKG T-wave ventricular repolarization, atrial systole SA node, cardiac cycle ventricular contraction longer, left heart failure pulmonary edema, right heart failure peripheral edema swollen ankles, atherosclerosis thromboembolism risk, coronary artery bypass), lymphatic system (thoracic duct, lymph flow interstitial to lymph capillaries to vessels to duct to veins, lymphedema, lymph nodes efferent vs afferent vessels, spleen splenic artery, hepatic portal system liver, tonsils crypts, thymus T cells), immune system (nonspecific response normal flora cytokines interleukins, fever pyrogens interleukins, interferons viruses, neutrophils most abundant phagocytosis, eosinophils basophils macrophages monocytes, memory B cells, MHC glycoprotein receptors, cell-mediated immunity macrophages cytokines enzymes phagocytosis, graft rejection, multiple sclerosis myelin sheath, anaphylaxis hives difficulty breathing), reproductive system (ovaries oogenesis primary oocyte secondary oocyte, ovulation ovarian follicle, fimbriae, myometrium uterine contraction, vagina functions except progesterone, cervix sperm viability seal dilation 10cm, secretory phase progesterone estrogen, testes sperm production, seminal vesicles ejaculatory duct vitamin C prostaglandins, prostate alkaline fluid, bulbourethral glands alkaline first secretion, testosterone, LH anterior pituitary, sperm midpiece mitochondria, fertilization acrosome corona radiata, gametes haploid, blastocyst ectoderm epidermis neural tube endoderm glands mesoderm cardiovascular, embryonic development first trimester heartbeat second trimester eyes light dark fingerprints third trimester fat, neurotization ectoderm convergence neural groove neural tube spinal cord), renal system (kidney location T12-L3, renal capsule tough fibrous protection, renal cortex nephrons, interlobular arteries afferent arterioles, efferent arterioles, bladder location anterior to vagina, bladder expansion elastic tissue ruggae, male urethra spongy region, glomerular capillaries high pressure afferent larger than efferent, colloid osmotic pressure proteins, emergency blood flow nervous system epinephrine afferent constriction, RAA system responds to low blood pressure, PCT reabsorption, loop of Henle water leaves descending not ascending, ADH dilute urine false, osmolarity PCT 300 mOsm/L loop of Henle 1200 mOsm/L, aldosterone release high K+ low Na+, diuretic increases nephron flow, cardiovascular baroreceptors, abnormal urine solute bile pigment, body water intracellular compartment, urine pH 5.0 normal acidic, chemical buffer systems bicarbonate phosphate protein, hypoventilation respiratory control alkaline pH, renal control remove acids bases, acidosis metabolic compensated hyperventilation). Perfect for Portage Learning students and A&P final exam preparation.
