Monica Tyler Chapter 5 Integumentary System 1 Which epidermal cell type is most numerous a keratinocyte 2 Which cell functions as part of the immune system c dendritic cell 3 The epidermis provides a physical barrier due largely to the presence of d keratin 4 Skin color is determined by d all of these amount of blood pigments oxygenation level of the blood 5 The sensations of touch and pressure are picked up by receptors located in b the dermis 6 Which is not a true statement about the papillary layer of the dermis b it is most responsible for the toughness of the skin 7 Skin surface markings that re ect points of tight dermal attachment to underlying tissues are called c exure lines 8 Which of the following is not an epidermal derivative c sensory receptor 9 An arrector pili muscle b can cause a hair to stand up straight 10 The product of this type of sweat gland includes protein and lipid substances that become odoriferous as a result of bacterial action a apocrine gland 11 Sebum d all of these lubricates the surface of the skin and hair consists of cell fragments and fatty substances in excess may cause seborrhea 12 The rule of nines is helpful clinically in b estimating the extent of a burn l 10 ll 12 13 14 Chapter 6 Bones and Skeletal Tissues Which is a function of the skeletal system e all of these support hematopoietic site storage providing levers for muscle activity A bone with approximately the same width length and height is most likely b short bone The shaft of a lone bone is properly called the c diaphysis Sites of hematopoiesis include all but 1 medullary cavities in bones of a healthy adult An osteon has e all of these a central canal carrying blood vessels concentric lamellae osteocytes in lacunae canaliculi that connect lacunae to the central canal The organic portion of matrix is important in providing all but b hardness The at bones of the skull develop from c brous connective tissue The remodeling of bone is a function of which cells b osteoblasts and osteoclasts Bone remodeling in adults is regulated and directed mainly by d mechanical stress e PTH Where within the epiphyseal plate are the dividing cartilage cells located c between the resting zone and the hypertrophic zone Wolff s law is concerned with b the shape of a bone being determined by mechanical stresses places on it Formation of the bony callus in fracture repair is followed by c bone remodeling The fracture type in which the bone ends are incompletely separated is a greenstick The disorder in which bones are porous and thin but bone composition is normal is b osteoporosis Chapter 8 Joints 1 1 exhibit a joint cavity c synovial joints 2 types are sutures and syndesmoses a brous joints 3 bones connected by collagen fibers a brous joints 4 types include synchondroses and symphyses b cartilaginous joints 5 all are diarthrotic c synovial joints 6 many are amphiarthrotic b cartilaginous joints 7 bones connected by a disc of hyaline cartilage or fibrocartilage b cartilaginous joints 8 nearly all are synarthrotic a fibrous joints 9 shoulder hip jaw and elbow joints c synovial joints 2 Freely movable joints are b diarthroses 3 Anatomical characteristics shared by all synovial joints include all except 1 presence of brocartilage 4 Factors that in uence the stability of a synovial joint include 1 all of these shape of articular surfaces presence of strong reinforcing ligaments tone of surrounding muscles 5 The description Articular surfaces deep and secure capsule heavily reinforced by ligaments and muscle tendons extremely stable joint best describes b the hip joint 6 Ankylosis means 1 immobility of a joint due to fusion of its articular surfaces 7 An autoimmune disorder in which joints are affected bilaterally and which involves pannus formation and gradual joint immobilization is d rheumatoid arthritis U l 0 Chapter 9 Muscles The connective tissue covering that encloses the sarcolemma of an individual muscle fiber is called the c endomysium A fascicle is a b bundle of muscle bers enclosed by a connective tissue sheath Thick and thin myofilaments have different compositions For each descriptive phrase indicate whether the filament is a thick or b thin b 1 contains actin a 2 contains ATPases b 3 attaches to the Z disc a 4 contains myosin b 5 contains troponin a 6 does not lie in the I band The function of the T tubules in muscle contraction is to c transmit the action potential deep into the muscle cells The sites where the motor nerve impulses is transmitted from the nerve endings to the skeletal muscle cell membrane are the a neuromuscular junctions Contraction elicited by a single brief stimulus is called a a twitch A smooth sustained contraction resulting form very rapis stimulation of the muscle in which no evidence of relaxation is seen is called 1 fused tetanus Characteristics of isometric contractions include all but a shortening During muscle contraction ATP is provided by 1 which provides ATP fastest a a coupled reaction of creatine phosphate with ADP 2 Which does do not require that oxygen be available a c a coupled reaction of creatine phosphate with ADP anaerobic glycolysis 3 Which provides the highest yield of ATP per glucose molecule b aerobic respiration of glucose 4 Which results in the formation of lactic acid c anaerobic glycolysis 5 Which has carbon dioxide and water products b aerobic respiration of glucose 6 Which is most important in endurance sports b aerobic respiration of glucose 10 The neurotransmitter released by somatic motor neuron is a acetylcholine 11 The ions that enter the skeletal muscle cell during the generation of an action potential are c sodium ions 12 Myoglobin has a special function in muscle tissue It c holds a reserve supply of oxygen in the muscle 13 Aerobic exercise results in all of the following except c increased size and strength of existing muscles cells 14 The smooth muscle types found in the walls of digestive and urinary system organs and that exhibits gap junctions and pacemaker cells is b unitary
