The SA Node is the heart's normal pacemaker. When the SA Node depolarizes, electrical signal spreads through the atrial muscle causing contraction.
Explanation:
Inherent rhythmicity / automaticity - The property of the pacemaker cells of the heart to start electrical sequence of depolarization and repolarization.
SA Node or Sino-atrial Node generates the electrical signal.
The electrical signal passes through internodal pathways, atrial fibres, atrioventricular node (AV Node), the bundle of His, Purkinje fibres, right bundle branch, left bundle branch.
Systole - Contraction of cells when the electrical signal of depolarization reaches the contractile cells.
Diastole - Relaxation of cells when the electrical signal of repolarization reaches the myocardial cells.
Answer:
A, C, D and E
Explanation:
In the assessment of legs, there are many systems that are combined for that part of the body to function optimally.
The reason that all the options are relevant in this question (except for B) specifically referring to legs, is that option B (the cardiovascular system) is not a main indicator of a problem with that part of the body specifically.
If something is wrong with the leg of a patient, there is a small likelihood of it being related to the cardiovascular system, because if the cardiovascular system is causing something to be wrong in the legs, it should not be limited to that section of the body. Hence, the other options are correct, but not option B.
Answer:
Brain
Explanation:
The parietal lobe is located near the center of the brain, behind the frontal lobe, in front of the occipital lobe, and above the temporal lobe. The parietal lobe contains an area known as the primary sensory area. This is where impulses from the skin, such as warmth, cold, pain, and touch, are interpreted.
Answer: A : yelling at a patient
Explanation:
Nonverbal communication (NVC) is the transmission of messages or signals through a nonverbal platform such as eye contact, facial expressions, gestures, posture, and the distance between two individuals. If yelling a a patient is making him pay attention then its A.
Answer:
The answer is Estradiol; LH and FSH; progesterone
Explanation:
during the menstrual cycle, Estradiol peaks first, LH and FSH peak next, and finally progesterone peaks.
