Question

2) The difference between the upper and lower limits of a class interval is called its__________ and ___________​

Answer 1

Answer:

� tendon - cordlike attachment

� aponeurosis - thin flat sheet

� fascia - thin flat sheets of connective tissues that wrap and bind parts of the body together

� raphe - junction of two muscles at a band of connective tissue to form a line of fusion, such as the linea alba

Basis for muscle contraction:

� a muscle receiving no nervous stimulus is relaxed or in a resting state - soft shape retained by surrounding collagen fibers

� when nervous stimuli applied beyond muscle�s threshold level, contraction results and tensile force is generated, constituting the active state

� the attached bone and/or mass that must be moved represents the load - whether a muscle actually contracts depends on the relative balance between the tensile force of contraction and the load to be moved (Fig. 10.6, p. 351)

Major contractile characteristics of a muscle include how rapidly it reaches maximum tension and how long it can sustain this tension

Tension and strength are directly related to the number of cross-bridges between muscle filaments
