What's the difference between muscle and quadriceps?

Muscle


Definition:

  • (n.) An organ which, by its contraction, produces motion.
  • (n.) The contractile tissue of which muscles are largely made up.
  • (n.) Muscular strength or development; as, to show one's muscle by lifting a heavy weight.
  • (n.) See Mussel.

Quadriceps


Definition:

  • (n.) The great extensor muscle of the knee, divided above into four parts which unite in a single tendon at the knee.

Example Sentences:

  • (1) The fasted rats also exhibited a threefold increase in glucose 1,6-diphosphate (G-1,6-P2) in the white quadriceps after 30 min of exercise, whereas no significant changes were observed in the red quadriceps or in liver.
  • (2) The morphometric data was not related to the age of the patient, disease duration, type of MND or muscle strength, thus suggesting that the progression and severity of MND and its prognosis cannot be judged on the basis of quadriceps muscle pathology alone.
  • (3) Protein and DNA content of quadriceps muscles from young adult rats were decreased by the low protein and protein-free diet.
  • (4) After 60 min recovery, exercise was performed for 8-10 min each at 20, 30, 40 and 50 W. Measurements of pulmonary oxygen uptake, heart rate, blood pressure, leg blood flow, and femoral arterial-venous differences of oxygen content and lactate were performed as well as determination of ATP, creatine phosphate (CP) inosine monophosphate (IMP) and lactate concentrations on biopsy material from the quadriceps muscle before and immediately after the intense exercise, and at 3, 10 and 60 min into recovery.
  • (5) Osteo-inductive activity of each protein fraction was determined by implantation in the quadriceps muscle pouch of mice.
  • (6) An interesting remark which should be done is the fact that the flexion of the neck inhibits the quadriceps myokymia whereas the extension makes them to appear and even worsen.
  • (7) Then, we evaluated G6PDH activity and RNA content in biopsied quadriceps muscle.
  • (8) Sixty-two healthy male and female volunteers were randomly assigned to four groups: (a) subjects who statically stretched the quadriceps muscle group before a step, (b) subjects who only performed a stepping warm-up, (c) subjects who both stretched and performed a stepping warm-up prior to a step test, and (d) subjects who only performed a step test.
  • (9) Quadriceps strength, relaxation rate, fibre-type composition and energy-turnover rate during a submaximal contraction have been measured in hypo- and hyper-thyroid patients and compared with findings in normal subjects.
  • (10) We report on the use of this flap to resurface the anterolateral aspect of the lower thigh and restore stability and extension to the knee joint following extensive damage to the quadriceps mechanism.

  • (13) A corrugated appearance of the patellar tendon on sagittal images indicates a reduction in the normal tensile force applied to it and indicates the need for careful evaluation of the patella and quadriceps tendon mechanism.
  • (14) The quadriceps had a reduced cross-sectional area, but the knee flexors were not reduced.
  • (15) As compared to the mean values of normal gravity controls, centrifuged dogs showed no differences in femur length; cross-sectional area, outer and inner radii at mid-shaft of the femur; dry weights of the biceps femoris, quadriceps femoris, and gastrocnemius muscles.
