Anatomy Stack 2
| Question | Answer |
|---|---|
| "What are the two classification schemes for joints?" | "Structural classification (based on connective tissue type or presence of joint capsule) and functional classification (based on degree of movement allowed)" |
| "What are sutures?" | "Found only in the skull; teethlike projections from adjacent bones interlock with each other" |
| "What is the origin of a muscle?" | "Point of attachment that does not move when the muscle contracts" |
| "What is the insertion of a muscle?" | "Point of attachment that moves when the muscle contracts" |
| "What are extrinsic foot muscles?" | "Muscles in the leg that pull on tendons that insert on bones in the ankle and foot; responsible for dorsiflexion |
| "What are intrinsic foot muscles?" | "Muscles located within the foot; responsible for flexion |
| "What are T tubules?" | "Transverse tubules that extend across the sarcoplasm at right angles to the long axis of the muscle fiber; formed by inward extensions of the sarcolemma; allow electrical impulses to move deeper into the cell" |
| "What is a triad?" | "A triplet of tubules—a T tubule sandwiched between two sacs of sarcoplasmic reticulum; allows an electrical impulse traveling along a T tubule to stimulate the membranes of adjacent sacs" |
| "What is the enteric nervous system (ENS)?" | "Located within intestinal wall; regulates digestive function; has some independent integration abilities |
| "What are glia (neuroglia)?" | "Glial cells that support the neurons" |
| "What is the sodium-potassium pump?" | "Active transport mechanism in plasma membrane that transports Na⁺ and K⁺ in opposite directions and at different rates; maintains an imbalance in distribution of positive ions |
| "What are local potentials?" | "Slight shift away from the resting membrane in a specific region of the plasma membrane" |
| "What are sympathetic rami?" | "Splitting and rejoining of autonomic fibers; autonomic motor fibers split from ventral ramus and head toward sympathetic chain ganglion" |
| "What are nerve plexuses?" | "Complex networks formed by the ventral rami of most spinal nerves (not T2 through T12) subdividing and then joining together to form individual nerves" |
| "Why do plexuses exist?" | "Spinal nerve fibers are rearranged according to their ultimate destination |
| "What are sympathetic chain ganglia?" | "Most sympathetic division ganglia that lie along either side of the anterior surface of the vertebral column; joined with other ganglia on same side; each chain runs from second cervical vertebra to level of coccyx" |
| "Describe the olfactory pathway" | "When odorants reach threshold level: receptor potential and action potential generated → passed to olfactory nerves in olfactory bulb → impulse passes through olfactory tract → thalamic and olfactory centers of brain for interpretation |
| "What are gustatory cells?" | "Sensory cells in taste buds; gustatory hairs extend from each gustatory cell into the taste pore" |
| "What are endocrine glands?" | "'Ductless glands'; many are made of glandular epithelium whose cells manufacture and secrete hormones; a few are made of neurosecretory tissue" |
| "What are tropic hormones?" | "Hormones that target other endocrine glands and stimulate their growth and secretion" |
| "What are sex hormones?" | "Hormones that target reproductive tissues" |
| "What are anabolic hormones?" | "Hormones that stimulate anabolism in target cells" |
| "What is follicle-stimulating hormone (FSH)?" | "In females: stimulates primary follicles to grow toward maturity; stimulates follicle cells to secrete estrogens; In males: stimulates development of seminiferous tubules of testes and maintains spermatogenesis" |
| "How long do RBCs live?" | "About 4 months" |
| "How long do WBCs live?" | "Few days (granular) to over 6 months (agranular)" |
| "What is blood volume in a young adult male?" | "Approximately 5 liters" |
| "What is the first heart sound (systolic sound)?" | "Believed to be caused primarily by contraction of ventricles and by vibrations of closing AV valves" |
| "What is the clinical significance of heart sounds?" | "Provide information about the functioning of the valves of the heart" |
| "What are the four chambers of the heart?" | "Two atria (superior 'receiving chambers' that receive blood from veins) and two ventricles (lower 'pumping chambers' that push blood into large vessels)" |
| "What is the formula for cardiac output?" | "CO (volume/min) = SV (volume/beat) × HR (beats/min)" |
| "What is stroke volume (SV)?" | "The volume of blood pumped per heartbeat." |
| "What is cardiac reserve?" | "The amount cardiac output can increase above resting CO |
| "How do lymphatic vessels begin?" | "They begin blindly in the intercellular spaces of soft tissues and do not form a closed circuit." |
| "What does adaptive immunity provide?" | "A specific defense against specific threatening agents." |
| "Where are lymphocytes densest?" | "Where they develop—in bone marrow |
| "What forms the external nose?" | "Bony and cartilaginous frame covered by skin containing sebaceous glands." |
| "What is the respiratory pressoreflex mechanism?" | "Arterial blood pressure controls breathing through this mechanism." |
