What system is most crucial for calcium?
The skeletal system is most crucial for calcium, as it provides structural support and stores 99% of the body's calcium. Calcium is essential for functions such as muscle contraction, nerve transmission, and blood clotting.
What is the methyl skeletal structure of the compound in question?
The methyl skeletal structure of a compound refers to the arrangement of carbon and hydrogen atoms in the molecule. It shows how the carbon atoms are connected to each other and to the hydrogen atoms.
How does crystal meth affect the skeletal system?
Crystal meth can have various effects on the skeletal system, including causing damage to bones and teeth through the reduction of blood flow and stimulation of bone resorption. Prolonged use of crystal meth can also lead to nutritional deficiencies that negatively impact bone health. Additionally, the drug's impact on appetite and overall health can contribute to skeletal issues.
What types of atoms are shown in a skeletal model of an organic molecule?
These are atoms of carbon.
What is the difference between a line bond and a skeletal structure in organic chemistry?
In organic chemistry, a line bond structure shows all the atoms and bonds in a molecule, while a skeletal structure only shows the carbon atoms and their connections.
Is epinephrine a vasodilator or vasoconstrictor?
Epinephrine is mainly a vasoconstrictor. It acts on alpha-adrenergic receptors in blood vessels, causing constriction and increasing blood pressure. However, it can also dilate blood vessels in certain tissues, like skeletal muscle, through its actions on beta-adrenergic receptors.
What is the target organ of epinephrine and norepinephrine?
The target organ for epinpehrine are many different organs and tissues, some of which include: the heart, blood vessels in skeletal muscle, blood cessels in skin and viscera, intestines, bronchioles, and the liver. Norepinephrine is the same for epinephrine.
What classification of drugs increases skeletal growth in children?
growth hormone replacements
What Neurotransmitter that activates skeletal muscle fibers?
Acetylcholine is the neurotransmitter that activates skeletal muscle fibers at the neuromuscular junction. It plays a crucial role in transmitting signals from motor neurons to muscles, leading to muscle contraction.
What is the relationship between the load attached to skeletal muscle and the initial velocity of skeletal muscle shortening?
The relationship between the load attached to skeletal muscle and the initial velocity of skeletal muscle shortening is inverse. As the load increases, the initial velocity of muscle shortening decreases. This is due to the increased force required to move a heavier load.
What is the sympathetic division also called?
increases blood flow to skeletal muscle.
What are the effect of aerobic and resistance exercise on skeletal muscles and other body organs?
increases bone strength and denserty
Why are calcium ions necessary for skeletal muscle contractions?
calcium increases the action potential transmitted along the scarcolemma
What does epinephrine do when binding to beta 1 receptors?
It stimulates both receptor with almost the same affinity
How can massage help the skeletal system?
Increases blood circulation which nourishes skeletal cells.Improves muscular balance .Can aid functional efficiency in terms of structural support / posture .Aids in healing of the affected tissue.
What happens to the strength of contraction during wave summation?
It increases about to about four times greater than a normal contraction for skeletal muscle.
A contraction in which a skeletal muscle does not shorten but its tension increases is called isometric?
An isometric contraction is the name given to a skeletal muscle that does not shorten, but increases tension. The muscles generate force to protect themselves.
