When the vasomotor center of our brain wishes to increase blood pressure, it increases ____________ signals causing ______.

dlinn [17]

When the vasomotor center of our brain wishes to increase blood pressure, it increases the heart rate signals causing The greater contraction of the heart causes more blood vessels to constrict, increasing the blood vessels' resistance.

By speeding the heartbeat, making the heart beat harder, and constricting some blood vessels, the sympathetic nervous system increases blood pressure. This will enhance the vessels' resistance.

What controls blood pressure by the vasomotor center?

The vasomotor center modifies the tone of the vascular smooth muscle. Both the local and systemic blood pressure are impacted by this. The vasomotor center produces increased sympathetic tone when blood pressure lowers. This causes an increase in blood pressure.

How is blood pressure regulated?

The autonomic nervous system has short-term control over blood pressure (ANS). Baroreceptors are capable of detecting changes in blood pressure. These are situated in the carotid sinus and aortic arch. High arterial pressure causes the blood vessel wall to stretch, activating the baroreceptors.

What systems regulate peripheral resistance in the vasomotor center?

The vasomotor center in the tunica media regulates smooth muscle contraction or vessel tone. Circulating output is impacted by changes in peripheral resistance, pressure, and flow. The majority of these neurons are in charge of causing sympathetic neurons to release the neurotransmitter norepinephrine.

The brain of an alzheimer's victim displays plaques, which are _____, and tangles, which are _____.

pav-90 [236]

Scientists can also glimpse the awful effects of Alzheimer's disease when they look at brain tissue beneath the microscope:

Alzheimer's tissue has numerous fewer nerve cells and synapses than a well brain.

Plaques, unusual clusters of protein particle, which are construct up between nerve cells. Dead and dying nerve cells contain tangles, which are produce of twisted strands of a further protein.

Scientists are not absolutely sure what causes cell death and tissue deficiency in the Alzheimer's brain, but plaques and tangles are key suspects.

State the level of organization of euglena onion bulb and blood

saw5 [17]

Answer:

The correct answer is -

Euglena - single-cell organism

Onion bulb - organ

Blood - tissue (connective tissue)

Explanation:

The level of organization of an organ, or organism could be cellular level, tissue level, the organ level, organ system, or a complete organism. These levels are formed by assembling the lower level of the organization.

Euglena is a single-cell eukaryotic organism found in freshwater. These organisms have a very simple level of an organism which is cellular level. The onion bulb is the organ of the onion plant composed of shortened, compressed, underground stems (tissue) that are an organ-level organization.

The blood is considered as connective tissue due to the blood cells present in the matrix called plasm thus, blood is connective tissue.
