Nerve impulses in the heart

In a healthy heart, nerve impulses originate solely within the heart itself. The wall of the right atrium contains special cells for this purpose. Specifically, in the sinus node, the natural pacemaker of the heart. Authors: ZDF/3sat/nano/Südkino F i l m p r o d u k t i o n GmbH/Berndt Welz/Hannah

Visual Perception – How It Works

Click here to see more videos: https://alugha.com/mysimpleshow Every day we perceive many visual impressions. We can differentiate a multitude of colors in a bunch of flowers, and we can respond in a matter of seconds when driving a car. But what do we actually know about visual perception? Learn t

The Polarimeter - Setup and Measurement

The polarimeter is an important measuring instrument for determining the specific angle of rotation of an optically active substance. This first video is exclusively about the construction of a polarimeter. Afterwards, a short measurement is also carried out. Only in another video will I explain how

The Polarimeter - How it works

This second video about the polarimeter is all about how it works. In particular, the polarization foils, polarization and analyzer are named, considered and described. Furthermore, it is discussed how the oscillation plane of linearly polarized light changes. Original: "Wolfgang Dukorn" Original:

Anatomy and function of the penis

The male penis consists of the root, shaft and glans. When a man is sexually aroused, his brain sends signals to the nerves in the erectile tissue in the shaft. The penis becomes stiff and erects. Translation and dubbing: alugha Click here to see more videos: https://alugha.com/TerraX Thumbnail

Endogenous Cannabinoids

When there is a chemical imbalance in the body, such as during stress, endocannabinoids are released. They bind to the matching receptors, regulating the activity of the nerve cells. This allows the body to counteract the imbalance. Authors: ZDF/Terra X/J. v. Kalkreuth/M. Richter-Jähring/D. da Cruz

Q 11 Mutarotation in glucose

alpha-glucose and beta-glucose are in balance. This can be demonstrated by measuring the angle of rotation of linearly polarized light. Original: "Wolfgang Dukorn" Original: German. All translations in this video have been done by the alugha AI.

What Causes the Halo Phenomenon?

When ice crystals at high altitudes in cirrus clouds refract sunlight, a halo appears. But a classic halo is only visible when the light exits at an angle of 22 degrees. Autor: ZDF/Terra Xpress/Autorenkombinat/Birthe Heer/Sebastian Kerz/Tobias Schönke/Maximilian Heß Translation and dubbing: alugha
