Is the following the correct order of steps leading to muscle contraction? (Yes or No) If you think the order is incorrect, then what would be the correct order? a. secretion of acetylcholine by the motor neuron b. attachment of acetylcholine to receptors on the motor end plate of the sarcolemma c. opening of sodium channels in the sarcolemma d. depolarization of the sarcolemma e. action potential reaching the sarcoplasmic reticulum f. release of calcium ions by the sarcoplasmic reticulum...

Smooth muscle, like striated muscle, utilizes Ca2+ as a signal molecule that can allow contraction to occur. However, smooth muscle does not have troponin or tropomyosin. Therefore, Ca2+ must interact with other proteins. Describe these relationships.

Put these steps in neuromuscular junction synaptic transmission and excitation-contraction coupling in chronological order. (Type the letters in the appropriate order with no spaces between them). 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...

During the excitation phase of the skeletal muscle cell contraction, the following occurs: 1) the muscle fiber develops tension and shortens 2) the muscle fiber relaxes and returns to its original length 3) nerve action potentials lead to muscle action potentials A growing long bone in a child has only two types of cartilage at the epiphysis. These two areas are 1) elastic cartilage and epiphyseal plate 2) epiphyseal plate and epiphyseal line 3) primary and secondary ossification centers 4)...
