Biol 348 Exam 2 Muscles 1&2 Questions With Complete
Solutions
A Correct Answers Dark = thick filaments (___ bands)
Abduction Correct Answers Moves away from longitudinal
axis
Actions Correct Answers -Movements produced by muscle
contraction
-Body movements
-For example, flexion, extension, adduction, etc.
-Described in terms of bone, joint, or region
Adduction Correct Answers Moves toward longitudinal axis
Agonists, antagonists Correct Answers _____________ and
___________ work in pairs
When one contracts, the other stretches
Such as flexors-extensors, abductors-adductors, etc.
aponeurosis Correct Answers Tendons usually have a thick,
cordlike structure. Sometimes, the tendon forms a thin, flattened
sheet, termed an _______________.
applied force Correct Answers Muscles provide ________
(AF) to overcome load (L)
Articular Cartilages Correct Answers -Pads articulating
surfaces
, Articulations Correct Answers -Body movement occurs at
joints (______________) where two bones connect
-Determines direction and distance of movement
-Joint strength decreases as mobility increases
Atrophy Correct Answers Muscle ___________
-Lack of muscle activity
-Reduces muscle size, tone, and power
axon Correct Answers . Each motor neuron has a long
extension called an ___________, or nerve fiber that branches
extensively at its terminal end
Bipennate Correct Answers -Fibers on both sides of tendon
-For example, rectus femoris
Bursa (bursae) Correct Answers -Pouch or Pocket of synovial
fluid
-Cushion areas where tendons or ligaments rub
-Bursitis
Cartilages Correct Answers -Cushion the joint
Fibrocartilage pad = meniscus (articular disc)
Circular Muscles Correct Answers -Also called sphincters
-Open and close to guard entrances of body
-For example, orbicularis oris muscle of the mouth
Convergent Muscles Correct Answers -A broad area converges
on attachment site (tendon, aponeurosis, or raphe)
