Problem 36

Consider the gedanken experiment discussed in Section2.6 in which a giant fl oodlight stationed 400 kmabove the Earths surface shines its light across themoons surface. How fast does the light fl ash acrossthe moon?

Step-by-Step Solution:
Step 1 of 3

Lecture objectives 15 Neuromuscular transmission 1. How does the movement of the myofibrils lead to muscle contraction Myosin head attaches to actin, ADP and P are released as myosin head pivots, moving to a low energy state. It pulls the actin filament with it towards the M line. ATP attaches to myosin, releasing it to the myosin head from the actin. As ATP is hydrolyzed to ADP and P the myosin head return to the pre stock high energy cocked position. 2. Describe and identify the motor unit A ​motor unit​ is made up of a​ otor​ neuron and the skeletal muscle fibers innervated by that ​ otor​ neuron's axonal terminals. Groups of​ otor units often work together to coordinate the contractions of a single muscle. A single branch motor neuron only contact a single muscle fiber. 3. What are the anatomical structures needed for muscle contraction Not answering specifically, found in all other answers. 4. ***Describe in detail the 3 phases of muscle contraction Phase 1 ​Neuromuscular Junction Stimulation Action potential arrives at the axon terminal of motor neuron. Voltage-gated Ca2+ channels open allowing Ca2+ which allows ACh to be released into the synaptic cleft via exocytosis. Ach then binds to reception on the sarcolemma/on junctional fold of the sarcolemma. ACh opens ion channels (nonselective monovalent cation receptors) that allow Na+ to enter the cell and K+ to exit the cell simultaneously. More Na+ goes in then K+ goes out which causes local change in membrane potential called the end plate potential. Termin
