Summary Introduction

Introduction:

The muscles of humans and other mammals are mixed and contain different proportions of slow and fast muscle fibers, depending upon their functions. Based on their rate of contraction and resistance to fatigue, they are classified as slow fibers, fast aerobic fibers, and fast anaerobic fibers.

One of the primary reasons that one individual is faster in a 50-meter sprint than another is a. a greater number of muscle fibers of smaller diameter. b. more oxidative fibers in the lower limb muscles. c. an enhanced ability to deliver oxygen to the muscles. d. a greater percentage of fast-twitch fibers in the lower limb muscles.
Most of the muscles of the skeleton are attached to areas very close to the joints, so their arms, although they are very small, their mechanisms allow the movement of the human body. (a) How are they considered from the point of view of force efficiency? (b) What are the biomechanical benefits?
A bacterial toxin is known to block the release of ACh at the motor end plate of skeletal muscle. Consequently, a. the skeletal muscle contracts with increasing force. b. the skeletal muscle contracts with increasing frequency. c. the ability to stimulate the muscle is impaired. d. other neurotransmitters would stimulate the muscle.
