The Muscular System: Neuromuscular Junction 1. What insulates each muscle cell? __________endomysium_______________ 2. Synaptic vesicles in the axon terminal of a motor neuron contain what neurotransmitter? __________acetylcholine_______________ 3. An action potential in the axon terminal of a motor neuron opens what type of ion channels? ____________Voltage-gated Calcium_____________ 4. By what means of membrane transport does the neurotransmitter leave the axon

myelination can all have an effect on the sciatic nerve and therefore the peak contractile force of B. Marinus. The diameter of the axon in the sciatic nerve would impact how fast the action potential is conceived down the axon to the synaptic cleft and muscle (Firmin‚ L. 2014). If one of the toads had a smaller axon diameter it would allow for resistance to movement to occur due to friction. The diameter of the axon in the sciatic nerve would therefore cause the peak contractile force to be reached at

a larger heart‚ and capillaries to circulate blood flow better to the muscles. So how does say athlete acquire these traits? Is it through genetics or just sheer hard work? “Until quite recently researchers commonly believed that percentages of muscle fiber types and aerobic power are more than ninety percent determined by heredity for males and females" (Ericcson 364). What this could mean is that speed process‚ ease of muscle growth‚ and even memory retaining are all passed down through our genes

ions during contraction of a skeletal muscle? Calcium is an important element for live. Calcium is found in the bones of animals and humans. In muscle contraction is produce as a result of Calcium ions ‚ Ca2+‚ It comes from rapid release from the cisternae of the sarcoplasmic reticulum which cause a chemical reaction between ATP and the myofilaments. Another important function of Calcium ions occurs during the state of resting muscle. During the state of resting muscle‚ calcium Ion is “maintaining

enzyme activity in skeletal muscle‚ particularly the activity of lactate dehydrogenase (LDH). LDH is a glycolytic enzyme which converts pyruvate to lactate in the following equation: LDH Pyruvate+ NADH ------------ Lactate + NAD The reaction above can move in both directions‚ forward (favored by Type II skeletal muscle) and reverse (favored by Type I skeletal muscle and the heart). Enzyme

Virtual lab 9 Activity 2: Determining the Latent Period 1. How long is the latent period? 2.78 msec. 2. What occurs in the muscle during this apparent lack of activity? Ca++ is being released from the sacroplasmic reticulum and filament movement is taking up slack. Activity 3: Investigating Graded Muscle Response to Increased Stimulus Intensity 1.
