Answer:
Pectoralis minor
Explanation:
Pecoralis minor is a thin, triangular muscle lies beneath the pectoralis major muscle. This muscle arises from the third ribs, fourth and fifth ribs.
The pectoralis muscles fans out from the shoulder upper ribs area. This muscle is involved in the coracoid process of scapula. The pectoralis muscle helps in the depression point of the shoulder.
Thus, the correct answer is option (D).
Answer:
D
Explanation:
The point of hands only CPR is to make it easier on those with a lack of training a give them a way to give care to someone who needs it even if they do not know how to, the point is that if you are not in sports med or EMT training then you will at least be able to help if no one else is around, otherwise use an AED
Answer:
High Blood Pressure. Hypertension increases one’s risk of cardiovascular disease as the blood vessel walls become irritated by the increased pressure exerted by the blood flowing through. As more and more damage is done to the vessel walls, plaque tends to form, in turn increasing the likelihood of atherosclerosis and coronary heart disease.
Answer:
1. dendrite = directs impulses toward the soma.
2. axon = conducts impulses toward the synaptic terminal.
3. perikaryon = region surrounding nucleus.
4. collateral branches = main branches of an axon.
5. synaptic terminal = enlarged end of an axon.
6. synaptic vesicles = contains neurotransmitters.
7. axon hillock = connects the cell body and axon.
8. Nissl bodies = clusters of RER and free ribosomes.
9. telodendria = fine branches of an axon.
10. myelinated internode = part of axon covered by Schwann cell.
11. neurilemma = Schwann cell's plasma membrane.
12. axolemma = membrane of the axon.
13. astrocyte = Forms the blood-brain barrier.
14. cell body = soma.
Answer:
Option (b).
Explanation:
Pulmonary ventilation is the mechanism of respiration in which the oxygen is inhaled in the body and carbon dioxide is exhaled out due to the pressure difference in the lungs and the environment.
The surface tension in the alveoli is decreased by the presence of surfactant. The increase in the surface tension of the alveoli increase the force that will require the additional muscles to work properly.
Thus, the correct answer is option (b).
