Answer:

Binding of acetylcholine to the receptor protein converts the protein to an open ion channel

Explanation:

Ionotropic receptors are those receptors that have binding sites for their messenger ligands and also have the capacity to alter shape enough to become an open ion channel,and thus allowing an increase in cross-membrane traffic of ions, thus altering the membrane potential.
Therefore, <em><u>Acetylcholine receptors on skeletal muscles are described as being ionotropic receptors because the binding of acetylcholine to the receptor protein converts the protein to an open ion channel</u></em>

Neurons in the ______ , control motor reflexes.

yan [13]

Neurons in the <u>spinal cord</u>, control motor reflexes, which allows rhythmic and automatic movements to be carried out.

The spinal cord represents the lowest level in the hierarchical system that regulates reflex motor activity, voluntary movements, and body posture.

Therefore, their neurons have been organized into circuits that participate in simple automatic gait movements and simple defensive movements (withdrawal of the muscle in the event of any aggression) through reflex responses.

The motor neurons of these circuits are located in the anterior horns where they are arranged forming the so-called "poles" of motor neurons, equivalent to true motor neuron nuclei.

Alpha motor neurons their axons are myelinated and they group together in the medulla and form columns that are known as motor nuclei.

Gamma (γ) motor neurons innervate muscle fibers of the muscle spindle.

Interneurons can be excitatory or inhibitory.

Therefore, we can conclude that neurons in the spinal cord, control motor reflexes, they present functional interactions between them and this allows rhythmic and automatic movements to be carried out with ease through reflex responses.

Use the normal ecg trace below to determine how many seconds the trace represents as well as the heart rate.

mezya [45]

Attached is the image of the concerned ECG reading.

In reading the ECG, first you read the heart rate. To read the heart rate, you must count for the number of small boxes in between QRS complexes, specifically R-R intervals. These number of small boxes will then be used to divide 1500. In this example, there are 20 small boxes between R-R intervals. 1500 divided by 20 is 75, so the heart rate of this ECG reading is 75 beats per minute.

<em>Another way, albeit less accurate, is to count the big squares between R-R intervals and instead of dividing it by 1500, you divide it by 300.</em>
