Chapter 29, Problem 10WIO
Summary Introduction
To explain:
The process how the muscles lengthen when you stretch.
Concept Introduction:
Muscles are composed of the thick band of myosin and thin band of actin. There are other proteins involved in the movement of the muscles like troponin, and tropomyosin. These muscles respond to the stimulus of contraction and relaxation by the transmission of the signal waves of impulse across the neuromuscular junctions at the nerve endings. The action potential is generated and moves ahead in the neurons.

Concentric, isometric or eccentric? Don't copy from Googlearrow_forward
- In an isometric contraction, how can the muscle stay the same length when the muscle is contracting? Can choose more than one - The muscle is not able to generate more (or the same amount) force than the load, preventing shortening of the muscle. - Calcium stops entering the sarcoplasm when the desired length is reached. - Elastic elements of the muscle stretch in response to the contraction of the muscle, so that the muscle stays the same size despite shortening sarcomeres. - The myosin heads detach from actin when they reach the desired length.arrow_forwardIndicate which of the following are true. Chronically shortened muscles will lose sarcomeres in series in order to maintain ideal amounts of myofilament overlap. Contractile force is proportional to the length of a muscle. Muscle organ contraction is all or nothing. Muscle cells are surrounded by an endomysium. Actin is the thick filament and Z-lines are where the cross-bridges zig-zag to adjacent actin filaments. Muscles with fewer motor units are weaker, i.e., capable of less force. A nerve impulse, calcium, and ATP are necessary for muscle contraction. Tendons attach bones to bones and help to limit the range of motion at joints. Muscle tissue is very dynamic and will respond to chronic stress by becoming stronger (making more myofilaments), chronic contraction by becoming shorter (losing sarcomeres in series), and stretching by becoming longer (adding sarcomeres in series). Myofilaments are actually long strands of proteins.arrow_forwardWhat stimulates Golgi tendon organs? A muscle is contracting with minimal tension. A muscle is stretched nearly to its limit. A muscle has become metabolically active. A muscle starts to relax after strenuous exercise.arrow_forward
- After learning about muscle fiber types in his anatomy and physiology class, Alex started to notice differences in the color of the turkeymeat he ate for lunch. Some of the meat was very white and someof it was much darker. From the color of the meat, Alex guessedwhich muscles the bird used for maintenance of posture and/or slowmovements, such as walking, and which muscles it used for quickermovements, such as running or flying. What type of muscle fiberpredominates in white meat? In dark meat? Explain how the colorof the meat relates to the function of the muscle.arrow_forwardWhat will happen in a muscle cell that has used up its supply of oxygen and ATP whenyou are exercising?

Use the sliding filament model to draw how thin filaments, thick filaments, and Z lines move during muscle contraction. Predict how perturbations of acetylcholine release, reception, or breakdown will influence muscle contraction. Predict how perturbations of actin, troponin, tropomyosin, myosin, or calcium would influence muscle contraction. Distinguish between the sympathetic and parasympathetic nervous system. Predict how changes in stress levels or situations would affect activation of the sympathetic and parasympathetic nervous system, levels of epinephrine and norepinephrine, and blood pressure.arrow_forward
- Place the steps leading to muscle contraction in the correct order. Calcium allows myosin to bind to the actin. A message travels down the axon of a nerve. Myosin pulls on the actin causing the muscle to shorten. An electrical wave of the action potential travels across the muscle cell and deep into the interior of the cell. The end of the axon of the nerve releases the neurotransmitter, acetylcholine. The electrical charge causes calcium to be released into the cytoplasm of the muscle. The neurotransmitter, acetylcholine travels across the space between the axon ending and the muscle. The neurotransmitter, acetylcholine, binds to receptors on the muscle.arrow_forwardGiven what you know about the functions of each muscle type, which one would be associated with the small intestine to help to move chyme through the digestive system?
