How does your integumentary system synthesize vitamin d? The epidermal layer of human skin synthesizes vitamin D when exposed to UV radiation. In the presence of sunlight, a form of vitamin D3 called cholecalciferol is synthesized from a derivative of the steroid cholesterol in the skin.
What part of the integumentary system produces vitamin D? Vitamin D is produced in the two innermost strata of the epidermis, the stratum basale and stratum spinosum. Vitamin D3 is made in the skin when the 7-dehydrocholesterol reacts with ultraviolet light of UVB type at wavelengths between 280 and 315 nm, with peak synthesis occurring between 295 and 297 nm.
How vitamin D is synthesized and activated in the body? Vitamin D from the diet, or from skin synthesis, is biologically inactive. It is activated by two protein enzyme hydroxylation steps, the first in the liver and the second in the kidneys.
Where does vitamin D synthesis occur in the skin? Upon exposure to UVB radiation, previtamin D3 is synthesized from 7-DHC in the skin, primarily in keratinocytes of the stratum basale and stratum spinosum layers of the epidermis.

What is full frame and crop sensor?
A full-frame sensor is a digital sensor that replicates the size of classic 35mm film cameras (36 x 24mm). A crop sensor is smaller, which means it crops the edges of your photo to produce a tighter field of view. The extent of this crop is called the crop factor.

What is the o2 sensor for?
Every new car, and most cars produced after 1980, has at least one oxygen sensor. Its job is to help the engine keep a certain air-to-fuel ratio that balances power, fuel economy and emissions. The O2 sensor checks the amount of oxygen in the exhaust, compared to the amount in the air.
How does an electronic gyro sensor work?
A gyroscope sensor works on the principle of conservation of angular momentum. It works by preserving the angular momentum. In a gyroscope sensor, a rotor or a spinning wheel is mounted on a pivot. The pivot allows the rotation of the rotor on a particular axis which is called a gimbal.
How to check speedometer sensor?

What does nike ipod sensor do?
The Nike+ iPod sensor sends information to the receiver using a built-in transmitter and antenna. It broadcasts its data at a radio frequency of 2.4 gigahertz using a proprietary protocol. In addition to transmitting data about a person’s running stride, it transmits a unique code that it uses to identify itself.
How do tire psi sensors work?
How does the Tire Pressure Monitoring System work? … Direct TPMS uses a sensor mounted in the wheel to measure air pressure in each tire. When air pressure drops 25% below the manufacturer’s recommended level, the sensor transmits that information to your car’s computer system and triggers your dashboard indicator light.
