Anp 1111 muscles part 1 - Midterm 2
Test Questions and All Correct
Answers 2025-2026 Set.
what do most muscles span? - Answer - joints
what is the origin? - Answer - the proximal attachment
- the end of the muscle attached to the immovable part
what is the insertion? - Answer - the distal attachment
- where the bone and muscle attach at the moveable part
what are muscles indirectly attached by? - Answer - tendons
- an aponeurosis
what wraps around a single muscle fiber? - Answer - endomysium
what wraps around a fascicle? - Answer - perimysium
what wraps around the whole muscle? - Answer - epimysium
do all skeletal muscles have fascicles? - Answer - yes
what are the 4 basic patterns of fascicles in skeletal muscles? - Answer 1. parallel
2. pennate
3. convergent
4. circular
describe parallel arrangement of fascicles - Answer - can be straplike (ex. sartorius)
- can be fusiform (fat then skinny) (ex. biceps brachii)
, - multipennate (ex. deltoid)
describe convergent arrangement of fascicles - Answer - muscle is triangular or fan-shaped
- ex. pectoralis major
describe circular arrangement of fascicles - Answer - concentric rings surround external
openings and contract to close openings
- ex. orbicularis oris
what are the 3 functional groups of muscles? can muscles change their roles? - Answer 1.
prime movers
2. antagonists
3. synergists
- they can change their roles based on movement
describe the prime mover and give an example - Answer - the muscle (can be multiple) that
does the main function
- ex. biceps brachii with elbow flexion
describe the antagonist and give an example - Answer - counter acts the prime mover
- can provide resistance to prevent overshoot or control rate of movement
- ex. biceps brachii and triceps brachii
describe the synergist and give an example - Answer - muscles that help the prime mover by:
- promoting the same movement
- reducing undesirable movements
- (some are fixators - muscles involved in posture)
- ex. rectus femoris in flexing the hip joint
what are the 7 ways we name skeletal muscles? - Answer 1. location (intercostals = rib cage)
2. shape (right and left trapezius = trapezoid)
3. size (maximus, medius, minimus, longus, brevis)
