Sequence of Events at the Neuromuscular Junction The site where a motor neuron excites a skeletal muscle fiber is called the neuromuscular junction. This activity will test your understanding of the sequence of events that occur at the neuromuscular junction. Using the images for help, place in the correct order of occurrence from left to right the events that occur at the neuromuscular junction after the action potential reaches the axon terminal. Termination of Neural Transmission Which of the following...

Choc Muscle fiber nucleus Myofibrilot muscle fiber Figure 10.15. Details of the neuromuscular junction. Label the structures labeled with capital letters. The numbers 1-4 indicate the chain of events that occur at the neuromuscular junction. Put these events in chronological order by placing a l in the blank before the first event, etc. Refer back to Figure 10.15 for information. Acetylcholine diffuses across the synaptic cleft. Nerve impulse reaches the axon terminal. Synaptic vesicles release acetylcholine into the synaptic cleft....

6. Draw the Neuromuscular junction and label the Following structures. Include the three substances that interfere with normal muscle contraction (both toxic and therapeutic). ID synapse, neurotransmitter synaptic cleft, axon terminal, synaptic bulb, synaptic vesicles, motor end plate, acetylcholine receptors, Junctional folds, acetylcholinesterase. 7. Describe or draw each of the contractile proteins (actin/myosin) and regulator proteins (troponin & tropomyosin). Explain the set up and how each participate in muscle contraction. Name the protein that attaches the sarcomere to the sarcolemma...

Put these steps in neuromuscular junction synaptic transmission and excitation-contraction coupling in chronological order. A. Ryanodine receptors open B. Voltage-gated Na+ channels open in the muscle cell membrane near the neuromuscular junction C. Tropomyosin rotates into the groove of the thin filament (out of the way of the myosin binding site) D. Depolarization of motoneuron axon terminal E. Ca2+ dissociates from troponin F. [Ca2+] rises in the muscle cell cytoplasm G. An EPSP occurs in the muscle cell H. Myosin...

True or False: The striations in skeletal muscle are formed by the arrangement of thick and thin filaments. 2. True or False: In skeletal muscle cells, the sarcoplasmic reticulum is continuous with the sarcolemma. 3. The interval between two Z lines is called a ________________. 4. At a neuromuscular junction, the space between the plasma membrane of the synaptic terminal and the motor end plate is the __________________. 5. An action potential (electric impulse) is transferred from a...

2. Curare blocks acetylcholine receptors at the motor end plate. This would result in: (1) Inability of the muscle fiber to respond to nervous stimulation (2) Increased muscle stimulation (3) Increased actylcholinesterase production (4) Lack of calcium uptake by the muscle fiber 3. The structure that is analogous to the Zline of skeletal muscle is the __ of smooth muscle. The structure that is analogous to troponin of skeletal muscle is _ muscle is ___ of smooth muscle. 4. Draw...

Part I—The Hospital At last the day had come. Mr. Th ompson was having his wisdom teeth removed. He was tired of the aches and pains and the sight of his puff y face in the mirror every morning. He felt helpless, lying on the gurney watching the ceiling lights whiz by as he was being wheeled to surgery. Mr. Th ompson had selected this particular oral surgeon because of the sign outside his practice that read: “We cater to...

The Brain on Mind Altering Drugs Psychoactive drugs alter brain function by acting at synapses in the brain, where they may mimic, enhance, or block the effects of natural signaling molecules (neurotransmitters). The neurotransmitter dopamine plays a particularly important role in creating the dependency aspect of both drug and behavioral addictions. Natural behaviors which enhance survival and/or reproduction, such as eating or engaging in sex, result in a surge of dopamine. Normally, this response helps individuals learn to repeat beneficial...
