Rio Salado Bio 201 Exam 2 Questions With
Answers Verified By Expert
Why are the paranasal sinuses at greater risk for infection? -
ANSWERS-their location adjacent to the middle ear cavity often
creates a high risk for infection
The tibia is in contact with which tarsus? - ANSWERS-talus
Ostealgia - ANSWERS-pain in the bone
Carpal bones - ANSWERS-trapezium, trapezoid, capitate,
hamate, scaphoid, lunate, triquetrum, pisiform
Tarsal bones - ANSWERS-calcaneus, talus, navicular, medial
cuneiform, Intermediate cuneiform, lateral cuneiform, cuboid
Chondromalacia patellae - ANSWERS-softening of the posterior
patella surface
Fibrous Joints - ANSWERS-joined by fibrous tissue, lack a joint
cavity
,Suture - ANSWERS-Type if fibrous joint, immovable, only in skull
Snydesmosis - ANSWERS-type of fibrous joint, slightly moveable
Gomphosis - ANSWERS-type of fibrous joint, peg in socket
Cartilaginous joints - ANSWERS-joints united by cartilage, lack a
joint cavity
Synchondroses - ANSWERS-Type of cartilaginous joint, united by
hyaline cartilage
Symphyses - ANSWERS-type of cartilaginous joint, united by
synovial fibrocartilage
joints - ANSWERS-found where articulating bones are separated
by a fluid-containing joint cavity, freely moving joints
rheumatoid arthritis - ANSWERS-accumulation of synovial fluid
skeletal muscle - ANSWERS-multinucleate cells, attach to bone
cardiac muscle - ANSWERS-walls of the heart, branching chains
of uni or binucleate cells
, Smooth muscle - ANSWERS-walls of hallow organs, uninucleate,
no striations, no presence of myofibrils of t tubules
Organization of skeletal muscles from microscopic to gross
anatomy - ANSWERS-Myofilaments create a sarcomere. Bundled
together, myofilaments form myofibrils, which bundle together to
form a muscle fiber (or muscle cell). Muscle fibers together form a
fascicle, which are further bundled together to form a full muscle.
Thick filaments - ANSWERS-myosin heads that contain actin
binding sites
Thin filaments - ANSWERS-two strands of actin subunits
resting membrane potential - ANSWERS-90 mV
wave summation - ANSWERS-the situation in which contractions
become stronger due to rapid stimulation rate. partial relaxation
occurs between contractions
multiple motor unit summation - ANSWERS-how a smooth
increase in muscle force is produced
treppe - ANSWERS-the pheromone in which the contraction
strength of a muscle increases, due to increased enzyme
efficiency during the warm-up
