Do cardiac muscle Conscious control?
Cardiac muscle is not under conscious control; it operates autonomously. It is regulated by the autonomic nervous system and intrinsic conduction system, which manage heart rate and rhythm without requiring conscious input. This allows the heart to continuously pump blood efficiently, even when a person is not actively thinking about it.
Where are circadian rhythms located?
Circadian rhythms are regulated by the suprachiasmatic nucleus (SCN) in the brain, located in the hypothalamus. The SCN receives input from light-sensitive cells in the retina, helping to synchronize internal body clocks with the external environment.
What are another names for input and output?
Input is often referred to as "data entry," "information input," or "user input," while output is commonly called "data output," "results," or "information output." In computing contexts, input can also be termed "feed" or "source data," and output might be described as "display," "results set," or "feedback."
How efficiency of linear regulated power supply calculated?
The efficiency of a linear regulated power supply is calculated by dividing the output power by the input power and multiplying by 100 to express it as a percentage. The output power is determined by the product of the output voltage and output current, while the input power is the product of the input voltage and input current. The formula can be expressed as: [ \text{Efficiency} (%) = \left( \frac{\text{Output Power}}{\text{Input Power}} \right) \times 100 ] Due to the inherent voltage drop across the regulator, linear power supplies typically have lower efficiency, especially when there is a significant difference between input and output voltages.
Why series resonance is termed as selective circuit?
Because they can be used to obtain or get an output (on a series connected resistance with them) for a specific frequency of the input signal. This is the ideal case, but in fact, the resonance circuit passes a band (not a single frequency) of input signals' frequencies to take them at the output terminal. They are also termed as ( filters or filtering circuits ). They are called selective as they function as if they select signals of specific frequencies to be passed to the output.
What current does the input required to give an output on Lm741?
It depends on the shunt feedback resistor on the op-amp, for example with a 10k feedback resistor connecting the output to the inverting input, 1 mA input current gives 10 volts signal output. The input terminal stays near zero voltage because of the high open-loop gain of the op-amp, so the inverting input is termed a 'virtual earth'.
What is the purpose of SMPS?
An SMPS is a switched-mode power supply. It is used to convert an unregulated power input into a regulated power output, often altering the voltage. In a modern computer, several components may be powered from the same power supply but will often require different regulated voltages. The SMPS fulfils this role.
What type of muscle would be considered autorhythmic?
Cardiac muscle is considered autorhythmic, meaning it has the ability to generate its own electrical impulses without the need for external stimulation. This property allows the heart to beat independently of nerve input.
Why is a common collector amplifier is called buffer?
Since its input impedance is much higher than its output impedance it is also termed a "BUFFER" for this reason it is also used in digital circuits with basic gates...
Which effector is not directly controlled by the autonomic nervous system?
Skeletal muscle is not directly controlled by the autonomic nervous system. Skeletal muscles are under voluntary control, with motor neurons from the somatic nervous system providing the neural input for their activation. Autonomic nervous system controls smooth muscle, cardiac muscle, and glands.
How does organization work?
The organ system work together as the nervous system recieves sensory input from internal and external sensory reports and directs the musculoskeleton system and gland to response the outside stimuli.
