Important — scope of this document: this set covers EMT 115 quiz 2 anatomy and physiology content only. It is a study aid designed to reinforce your understanding — not a brain dump or leaked exam. What's covered: Skeletal system – axial skeleton components including skull, vertebral column, and rib cage, facial bones including maxilla, mandible, nasal bones, zygomatic bones, palatine bones, lacrimal bones, inferior nasal conchae, and vomer, non-facial bones including temporal, parietal, frontal, and ethmoid, greater trochanter of the femur and muscle attachment Muscular system – skeletal muscle also called voluntary or striated muscle, smooth muscle, cardiac muscle, forearm movement including pronation and supination, radius and ulna function Respiratory system – oxygen percentage in room air at 21%, negative pressure breathing and diaphragm contraction, thoracic cavity volume changes, vital capacity decline in elderly, loss of lung elastic recoil, reduced respiratory muscle strength, right lung with 3 lobes and left lung with 2 lobes, hemoglobin binding to oxygen, oxygen and carbon dioxide exchange Cardiac system – sinoatrial (SA) node as natural pacemaker, electrical impulse initiation, atrioventricular (AV) node, Bundle of His, Purkinje fibers, cardiac conduction system, cardiac output determined by heart rate multiplied by stroke volume, preload and afterload, contractility of ventricles, heart rate increase during stress Nervous system – cerebrum responsible for higher brain functions including thought and sensory processing, occipital lobe for visual processing, temporal lobe, frontal lobe, parietal lobe, cerebellum for balance and coordination, brainstem, gray matter and cortex, foramen magnum and spinal cord connection, occipital condyle, sella turcica Endocrine system – hormone release for homeostasis, hormonal imbalances causing fatigue, weight changes, and mood swings, endocrine system regulation of bodily functions Circulatory system – blood volume loss compensation, increased heart rate, vasoconstriction, decreased blood pressure, immediate EMT action for trauma blood loss, intravenous fluids, tourniquet application Anatomical terminology – dorsal meaning posterior or back side, anterior, proximal vs distal, elbow proximal to wrist, wrist distal to elbow, prone position face down, supine position face up, lateral, medial Patient positioning – Trendelenburg position for increased venous return and improved blood flow to vital organs, supine with legs elevated higher than head, recovery position, Fowler's position Psychosocial development – adolescent identity formation and consolidation, antisocial behavior and peer pressure peaking in eighth or ninth grade, increased anxiety and peer pressure, toddler and preschooler rapid physical growth and motor skill development, preschool safety awareness compared to toddlers Aging and development – vital capacity decline with age, decreased cardiac output in elderly, chest wall rigidity, diaphragm weakness, age-related changes in respiratory and cardiac function Trauma and injury – foramen magnum injury and neurological deficits, occipital lobe injury and visual disturbances, zygomatic bone fracture and impaired facial symmetry and chewing, hip fracture and greater trochanter functional abilities
