A&P mid pract 9 20 23 Answer Section MULTIPLE CHOICE 1. ANS: B The thigh is proximal to the foot (closer to the point of attachment to the torso). PTS: 1 2. ANS: A The sagittal plane divides the body into a right and left halves. PTS: 1 3. ANS: C The electrons are in orbits surrounding the nucleus. The protons and neutrons are located within the nucleus. PTS: 1 4. ANS: C An anion is a negatively charged ion (Cl - ). PTS: 1 5. ANS: D [H+] refers to hydrogen ion concentration; the brackets mean concentration. PTS: 1 6. ANS: D The word ferrous refers to iron (FE 2+ ). PTS: 1 7. ANS: C An isotope is an atom that has the same atomic number (numbers of protons) but a different atomic weight (differing numbers of neutrons). PTS: 1 8. ANS: B The nucleus is the control center of the cell because it contains most of the DNA, the molecule that holds the genetic code that determines protein synthesis. PTS: 1 9. ANS: B Diffusion is a passive transport process causing water and solute to diffuse down their concentration gradients. PTS: 1 10. ANS: B DNA, the double-stranded nucleotide that carries the genetic code, is called the blueprint for life.

PTS: 1 11. ANS: B Transfer RNA (tRNA) transfers the amino acids from the cytoplasm to the ribosomes where the protein is assembled. PTS: 1 12. ANS: B Gluconeogenesis is a process (usually in the liver) that makes glucose from protein. PTS: 1 13. ANS: B Athlete’s foot and ringworm are localized fungal (mycotic) infections. PTS: 1 14. ANS: D The visceral (referring to organs) pleura form the outer lining of the lungs. PTS: 1 15. ANS: C The intercellular matrix of bone (osseous tissue) is the hardest of all connective tissue. PTS: 1 16. ANS: A The epidermis has five layers or strata, including the stratum germinativum (innermost) and stratum corneum (outermost). PTS: 1 17. ANS: C Freckles and moles result from a collection of melanin. Vernix caseosa is a white cream cheese  like covering. Bilirubin causes a yellowing of the skin. PTS: 1 18. ANS: B Both glands are classified as modified sweat glands; mammary glands secrete milk; ceruminous glands secrete ear wax. Despite the fact that they are sweat glands, they do not regulate body temperature. PTS: 1 19. ANS: D Fontanels are holes in the fetal and infant skull that eventually fuse. They allow for the growth of the brain (expansion of the infant skull). PTS: 1 20. ANS: C The epiphysis is located at the end of a long bone. The diaphysis is the shaft of a long bone. The periosteum is the outer connective tissue membrane surrounding the diaphysis of the long bone. PTS: 1

21. ANS: B The ischial tuberosity is part of the coxal bone; the ischium contains the ischial tuberosity (the part of the coxal upon which you sit). PTS: 1 22. ANS: B Fontanels are called the baby’s “soft spots.” They are areas where there are no skull bones. PTS: 1 23. ANS: B Actin is a contractile protein located within the sarcomeres of the muscle cell; it is also called the thin filament. PTS: 1 24. ANS: B A tendon is a connective tissue band that attaches muscle to bone. PTS: 1 25. ANS: C You sit on your gluteus maximus. The latissimus dorsi is located on the lower back. The rectus femoris is located in the thigh and the gastrocnemius, in the leg. PTS: 1 26. ANS: D Recruitment refers to the use of additional muscle cells to increase the force of contraction. A twitch is a single muscle contraction. A contracture develops as muscle tissue is replaced with connective tissue during periods of immobilization. Ossification refers to bone formation. PTS: 1 27. ANS: C The nodes of Ranvier are areas of the axon that are not covered by myelin sheath. The exposed axonal membranes (nodes of Ranvier) allow the action potential to jump from node to node, thereby increasing conduction velocity. PTS: 1 28. ANS: C The outward leak of K + from the resting (unstimulated) cell causes the inside of the neuron to become negative. K + is a positively charged ion (cation) so its loss from the neuron allows the intracellular anions (negative ions) to dominate. The internal negativity of the unstimulated neuron is called the resting membrane potential. PTS: 1 29. ANS: D The corpus callosum connects the right and left cerebral hemispheres. PTS: 1 30. ANS: C

Spinal anesthesia is injected into the subarachnoid space (lumbar region) where it “deadens” the nerves to the lower part of the body. PTS: 1 31. ANS: A The oculomotor, trochlear, and abducens nerves all innervate the extrinsic eye muscles. PTS: 1 32. ANS: D The gag reflex is mediated by the glossopharyngeal nerve (CN IX). PTS: 1 33. ANS: A A person with Bell’s palsy is unable to blink on the affected side, so requires eyedrops in order to moisten the cornea and prevent corneal ulceration. PTS: 1 34. ANS: C A cholinergic fiber secretes acetylcholine (ACh) as its neurotransmitter. Norepinephrine is secreted by the adrenergic fibers; epinephrine (adrenalin) is secreted by the adrenal medulla. PTS: 1 35. ANS: A A nociceptor detects pain. H + is detected by chemoreceptors; light is detected by photoreceptors. Humans do not have receptors that detect radiation. PTS: 1 36. ANS: B The middle ear contains three tiny ossicles (malleus, incus, and stapes) that are concerned with sound transmission (bone conduction). PTS: 1 37. ANS: D The temporal lobe is concerned with hearing. The occipital lobe is concerned with vision; the cerebellum is primarily concerned with skeletal muscle coordination. PTS: 1 38. ANS: B The vitreous humor, the gel in the posterior cavity of the eyeball, maintains the shape of the eyeball. It also gently pushes the retina against the choroid, thereby maintaining blood flow to the retina. PTS: 1 39. ANS: A Contraction of the radial muscles (iris) causes pupillary dilation or mydriasis. Movement of the eyeball is achieved by contraction of the extrinsic eye muscles. PTS: 1 40. ANS: B

Pinpoint pupils are caused by contraction of the circular muscles of the iris. Darkness, the use of mydriatic drugs, and contraction of the radial muscles cause mydriasis (dilation of the pupils). PTS: 1
