Why do teens pose for photos by bending forward at the waist?
obviously cause they want to show what they dont have
Dihydropyridine refers to a class of chemical compounds that are derivatives of pyridine, specifically characterized by a saturated, six-membered ring containing five carbon atoms and one nitrogen atom. These compounds are primarily known for their use as calcium channel blockers, which are commonly prescribed to treat hypertension and angina by relaxing blood vessels. Examples of dihydropyridine drugs include amlodipine and nifedipine. Their mechanism involves inhibiting calcium influx into vascular smooth muscle and cardiac cells, leading to vasodilation and reduced cardiac workload.
What muscle controls breathing?
The diaphragm, the external intercostal and the interchondral portion of the internal intercostal muscles are the main muscles that control breathing. Other muscles are sometimes used, but only if the person has a breathing disorder or if the body needs energy very quickly.
What does muscle cells produce under anaerobic conditions?
It's causes lactic acid fermentation to take place, which causes a build up of lactic acid. Only 2 ATP are made in oppose to the 34-38 made by aerobic respiration through cellular respiration
What are examples of involuntary muscle movement?
heart, so cardiac muscle. Smooth muscle is also involuntary in the intestines.
Levator ani and coccygeus; strengthening these muscles helps in the delivery of the child by resisting downward forces when "pushing."
Are subthalamopallidal fibers and striatopallidal fibers the same thing?
No, they are not the same, but they share a common target (the pallidum).
Subthalamopallidal fibers project from the subthalamic nucleus to the globus pallidus.
Striatopallidal fibers project from the striatum into the globus pallidus.
What region contains only actin and no myosin?
The region that contains only actin and no myosin is the I band of a sarcomere, which is the structural unit of a muscle fiber. The I band appears lighter under a microscope and is located on either side of the Z line. It consists solely of thin filaments (actin) and is important for muscle contraction and relaxation. The presence of only actin in this region allows for the sliding filament model of muscle contraction to occur effectively.
What is voluntary restriction?
Voluntary restriction refers to the self-imposed limitations individuals or groups choose to adopt in order to achieve specific goals or maintain certain standards. This can manifest in various contexts, such as dietary choices, environmental practices, or ethical consumption. Unlike mandatory regulations, voluntary restrictions are made out of personal conviction or social responsibility, often reflecting a desire for positive change or self-discipline. Such choices can contribute to broader movements, like sustainable living or health improvement.
What is insertion loss in sound attenuator?
Insertion loss in a sound attenuator refers to the reduction in sound power level that occurs when a sound wave passes through the attenuator. It is typically measured in decibels (dB) and quantifies how much sound energy is lost due to the attenuator's materials and design. High insertion loss indicates effective sound attenuation, while low insertion loss suggests that the attenuator may not be as effective in reducing sound levels. This parameter is crucial for designing systems that require noise control, such as HVAC systems or industrial applications.
What is the strongest muscle in world?
Well, I would take this as the strongest man in the world so that's Edison Jones, Daniel Bruce and David Bruce.

How is the hypoglossus muscle attach to the hyoid?
there´s no any "hypoglossal muscle"!
do you mean HYOglossal muscle?
What is the advantage of having muscles that run in different angles in the stomach?
For structural support. If your look at any of the old Westerns where they show trains going over a bridge above a valley, you will see vertical supports (rectus femoris muscle) and diagonal supports (oblique muscles) and transverse beams (rectus abdominis muscle). The engineering that we use, even, today is based on basic physical principles that nature has been using for millions of years to build living organisms like our bodies.
What is the supine flexion position?
supine flexion is lying in supine (on your back) while "flexing" (bending) your knees into your stomach and keeping your head off the floor
Could the baby be in your rib cage?
yes The baby is not actually IN your ribcage, but towards the end of pregnancy, if it is a kicker they can really feel bruised.
