The signal transmission process of the myoneural junction involves the following parts: axon terminals, pre-synaptic cell, synaptic cleft, receptors, and post-synaptic cell. Firstly, a nerve impulse will go to the axon terminals. Once it reaches the terminals, a molecule, called the neurotransmitter will be released. This neurotransmitter is stored in the pre-synaptic cell, which is attached to the axon terminals. For this process, the specific neurotransmitter ejected is called acetycholine or Ach. This Ach will then proceed to the synaptic cleft, the gap between the pre-synaptic cell (motor neuron) and the post-synaptic cell (muscle cell), and then bind to the receptors of the muscle cell.
Acetylcholine will diffuse and once adequate amount of Ach is ejected, the sarcolemma, or the membrane of the muscle cell, will be open to positive sodium (NA+) ions to enter the cell and positive potassium (K+) ions to be excreted out from the cell. Since NA+ enter more into the muscle cell than K+ leaving out of the cell, the sarcolemma will have a plethora of positive ions thus changing the electrical state of the sarcolemma causing it to have additional pathways solely for NA+ entrance. This occurrence would generate an electric current called action potential. When this current goes out of hand, the entirety of the sarcolemma would be conducted by electric impulses which results to muscle contractions. <span />
Answer:
This inventory system is usually used to manage instruments and supplies for individual surgical procedures. A cart filled with instruments and supplies is assembled for each specific procedure and delivered to the user unit, usually the operating room.
Explanation:
CPR is an emergency method of heart pumping in case of attacks and includes artificial ventilation. 100 compressions should be performed every minute.
<h3>What is CPR?</h3>
CPR is a cardiopulmonary resuscitation method of an emergency first aid tool used as a life-saving technique in case of heart attacks and drowning.
CPR is given to a person when the heart rate is very less and the pulse rate is very faint. The rate of the compression varies for age groups and should be given with a perfect rhythm and sync.
Cardiopulmonary resuscitation should be given as 30 compressions and then artificial breath or ventilation in between followed by another 30 compressions.
Therefore, option C. 100 compression in 1 minute is correct.

An individual's right to take risks should be exercised carefully considering themselves as well others.
<h3>What are the effects of individual's decisions on others?</h3>
An individual's right always have an effect on others, either positively or negatively.
An individual's right to take risks for example can endanger the person's life as well as the loves of others.
For example, individuals taking risks while driving can put their life at risk of accidents which could also affect others.
Therefore, it is important that an individual exercises his or her right to take risks carefully considering themselves as well others.
