Why do muscles need both an origin and an insertion point to properly function

Health
1 answer:
zzz [600]2 years ago

Answer: The origin is where the muscle joins the stationary bone. The insertion is where it joins the moving bone. ... At the bone, the fibres of the tendon are embedded in the periosteum of the bone. This anchors the tendon strongly and spreads the force of the contraction, so the tendon won't tear away easily.

What is responsible for the lub & dub sound that you hear when using a stethoscope?.
Aleks [24]

A continual "lub-dub, lub-dub" is a common way to characterize the sounds. The mitral valve and tricuspid valve closing is the source of the first "lub-dub." Following the first "lub-dub," the second "lub-dub" is made by the aortic and pulmonary valves shutting.

A blood backflow brought on by the heart's mitral valve failing to seal securely. When the mitral valve of the heart fails not close completely, blood can flow backward inside the heart, a condition known as mitral valve regurgitation. Breathing difficulties, weariness, dizziness, and an erratic, fluttering heartbeat are all symptoms. Treatment might not be  necessary for everyone. Between the heart's two right chambers is where the tricuspid valve is located. There are three little flaps of tissue that make up the tricuspid valve (called cusps, or leaflets). These valve flaps open to let blood to flow from the right atrium, which is the upper chamber, to the right chamber, which is the lower chamber (right ventricle).
