Question

An electrocardiogram actually records The contraction and relaxation of the myocardium electrical changes that occur in the myocardial cell blood flow through the heart changes in pressure in the left ventricle The action of sympathetic nervous system _____________ blood pressure, and the actions of parasympathetic nervous systems ______________ blood pressure. Increase; decrease Increase; increase Decrease; increase Decrease; decrease The QRS complex on an EKG represents depolarization of the atria repolarization of the atria depolarization of the ventricle repolarization of the ventricle The sounds heard in an artery when measuring the blood pressure are called Bruits sounds of korotkoff doppler wave murmur Control of the blood pressure is coordinated by this part of brain cerebrum pons medulla oblongata cerebellum Lymph node contain red and white pulp have germinal center where lymphocyte divides filter the blood are attached to the blood vessels

Explanation / Answer

1

records electrical changes that occur in the myocardial cell

2

Increases ; decreaess

3

QRS complex represents depolarization. of ventricular.

4

Korotkoff

5

medulla oblongata

6

Contains white pulp and red pulp.

sympathetic nervous system : it can quicken heart rate; augment bronchial sections; diminish motility (development) of the internal organ; contract veins; increment peristalsis in the throat; cause pupillary widening, piloerection (the creeps) and sweat (sweating); and raise pulse

=======================

The medulla oblongata (or medulla) is situated in the hindbrain, front to the cerebellum. It is a cone-formed neuronal mass in charge of autonomic (automatic) capacities going from heaving to wheezing. The medulla contains the cardiovascular, respiratory, heaving and vasomotor focuses and along these lines manages the autonomic elements of breathing, heart rate and circulatory strain.

The knob is an old term for the medulla oblongata and in cutting edge clinical use the word bulbar (as in bulbar paralysis) is held for terms that identify with the medulla oblongata, especially in reference to therapeutic conditions. The word bulbar can allude to the nerves and tracts associated with the medulla, furthermore by relationship to those muscles innervated, for example, those of the tongue, pharynx and larynx.

===============================================

Lymph hubs are little, bean-molded organs all through the body. They are a piece of the lymph framework, which conveys liquid (lymph liquid), supplements, and waste material between the body tissues and the circulation system. The lymph framework is a vital part of the insusceptible framework, the body's protection framework against ailment.
