Concept explainers

Muscle Action

A change in the body or a bodily organ as a result of its functioning is referred to as an action. Muscle action can be defined as the specific movement of a bodily part generated by the contraction of a muscle. The muscle proteins actin and myosin are the important contractile proteins involved in muscle action. Muscle contraction, in addition to movement, serves several other important functions in the body, including posture, heat generation, and joint stability. Muscle contraction maintains posture, which includes standing and sitting.

Human Anatomy & Physiology I (BIO168) Sequence of Events for Muscle Contraction Practice Worksheet See if you can place the events that occur during muscle contraction and relaxation in their proper order. Insert numbers in the paces provided to order the events in the proper sequence. _____ A. An electrical impulse travels over the sarcolemma and inward along the T-tubules, causing sacs in the sarcoplasmic reticulum to release calcium. ____ B. The release of ACh stops and acetylcholinesterase breaks down any remaining ACh. _____ C. Troponin and tropomyosin prevent the myosin heads from grasping the thin filament, and the muscle fiber relaxes. _____ D. An electrical impulse causes small vesicles at the end of a motor neuron to release the neurotransmitter acetylcholine (ACh). _____ E. Calcium binds with the troponin on the actin filament, exposing attachment points. _____ F. ACh diffuses across the synaptic cleft, where it stimulates receptors in the…
ngs. QUESTION 25 What is the difference between ballistic and proprioceptive neuromuscular facilitation (PNF)? Ballistic stretching involves moving quickly, bouncing, or using momentum to produce a stretch. This type of stretch is often viewed as necessary for sport movements and should be reserved for coaching and conditioning athletes and not used in general physical education. An example would be bouncing down repeatedly to touch the toes. Proprioceptive Neuromuscular Facilitation (PNF) is a static stretch using combinations of active and passive stretching techniques. This specialized static stretch uses a contraction-relaxation combination of movements, taking advantage of reflexes and neuromuscular principles to relax the muscles being stretched. Proprioceptive Neuromuscular Facilitation (PNF) involves moving quickly, bouncing, or using momentum to produce a stretch. This type of stretch is often viewed as necessary for sport movements and should be reserved for coaching and…

Explain how hand dynamometry might be used to assess a patient's need for surgery to release carpal tunnel compression. O Hand dynamometry measures electrical activity of the median nerve, which will be reduced if the median nerve scompressed. Hand dynamometry measures grip strength, which will be reduced if the median nerve is compressed. O Hand dynamometry measures grip strength, which will be increased if the median nerve is compressed.
