Frage 1
Frage
How are skeletal muscles named?
Antworten
-
Shape (eg. deltoid = triangle; trapezium = trapezoid) and relative size (eg. Maximus = largest, minimus = smallest, longus = long)
-
Direction of fibers or fascicles - eg. Rectus (fibers run straight), transversus and oblique (fibers run at angles to an imaginary defined axis) and ACTION (eg. flexor or extensor = muscles that flex or extend)
-
Location (eg. Bone or body region associated with the muscles) and number or origins (eg. biceps = 2 origins, triceps = 3 origins)
-
All of the above plus location of attachments (named according to point of origin or insertion)
Frage 2
Frage
What are the different arrangements of fascicles?
Frage 3
Frage
What is a circular arrangement of fascicles?
Antworten
-
Fascicles arranged in concentric rings (e.g., orbicularis oris)
-
Fascicles converge toward a single tendon insertion (e.g., pectoralis major)
-
Fascicles parallel to the long axis of a straplike muscle (e.g., sartorius)
-
Spindle-shaped muscles with parallel fibers (e.g., biceps brachii)
Frage 4
Frage
What is a convergent arrangement of fascicles?
Antworten
-
Fascicles converge toward a single tendon insertion (e.g., pectoralis major)
-
Fascicles parallel to the long axis of a straplike muscle (e.g., sartorius)
-
Spindle-shaped muscles with parallel fibers (e.g., biceps brachii)
-
Short fascicles attach obliquely to a central tendon running the length of the muscle
(e.g., rectus femoris)
