If the cost of electrical energy is at the rate of ₹4 per kWh, then what would be the decrease in the power of all fans to decrease the electricity bill by 50% ? (Take 1 month = 30 days)

Give four examples. Answer: The difference between the action of a beating heart and reflex action is given in the following table: Beating of a heart Reflex Actions Involuntary action that cannot be controlled by will Reflex actions are actions which occur in sudden response to stimulus . It does not require any stimulus to work. Require the occurrence of stimuli Regulated by the brain Regulated by the spine Do not involve the use of Skeletal Muscles . Use Skeletal Muscles . Performed throughout the course of one’s life . Are performed in response to stimulus in cases of emergency Can be quick or slow Reflex actions are always quick .

Involuntary actions Reflex actions Involuntary actions are the actions which are not controlled by our will. Reflex actions are the sudden action in response to something. They do not need any kind of stimulus to work. They required stimulus for its action. These actions are regulated by the brain. These actions are regulated by the spinal cord. They do not involve skeletal muscle. They do involve skeletal muscle. These actions are performed throughout one’s life. These actions are produced in response to an event of an emergency. This action may be quick or slow. Reflex actions are always quick. For example - The beating of the heart is an involuntary action.- Salivating when food is put in the mouth. For example- Immediate withdrawal of hands upon touching a hot cup of tea.- Closing the eyes, when bright light is focused. Note: An involuntary action is performed without the control of the nervous system.An involuntary action is unintentional and we cannot do it by thinking about it even if we wanted to. In the medical field, reflexes are often used to assess the health of thenervous system. We might imagine that reflexes are immutable (unchangeable). But in reality, however, most reflexes are flexible and can be substantially modified to match the requirements of the behaviour.

Learning Objectives By the end of this section, you will be able to: • Compare the structure of somatic and autonomic reflex arcs • Explain the differences in sympathetic and parasympathetic reflexes • Differentiate between short and long reflexes • Determine the effect of the autonomic nervous system on the regulation of the various organ systems on the basis of the signaling molecules involved • Describe the effects of drugs that affect autonomic function The autonomic nervous system regulates organ systems through circuits that resemble the reflexes described in the somatic nervous system. The main difference between the somatic and autonomic systems is in what target tissues are effectors. Somatic responses are solely based on skeletal muscle contraction. The autonomic system, however, targets cardiac and smooth muscle, as well as glandular tissue. Whereas the basic circuit is a reflex arc, there are differences in the structure of those reflexes for the somatic and autonomic systems. The Structure of Reflexes One difference between a somatic reflex, such as the withdrawal reflex, and a visceral reflex, which is an autonomic reflex, is in the efferent branch. The output of a somatic reflex is the lower motor neuron in the ventral horn of the spinal cord that projects directly to a skeletal muscle to cause its contraction. The output of a visceral reflex is a two-step pathway starting with the preganglionic fiber emerging from a lateral horn neuron in the spinal cord, o...
