Question

The most common form of reflex arc is the three-neuron arc, which consists of a sequence of neurons receiving sensory information, transmitting this information into the central nervous system for processing, and finally signalling muscles. What is the correct orderf neurons in such a reflex? unipolar- multipolar ntermeuron efferent- interneuron unipolar afferent+ interneuron bipolar efferent afferentinterneuron-

Answer 1

Ans) afferent --> interneuron--> efferent

Explaination:

Three types of neurons are involved in this reflex arc, but a two-neuron arc, a reflex is called the reflex arc. It consists of an afferent (or sensory) nerve, usually one or more interneurons within the central nervous system, and an efferent (motor, secretory, or secreto-motor) nerve.

Ans) neurotransmitter

Explaination:

At a chemical synapse, one neuron releases neurotransmitter molecules into a small space (the synaptic cleft) that is adjacent to another neuron. The neurotransmitters are contained within small sacs called synaptic vesicles, and are released into the synaptic cleft by exocytosis.

Ans)Acute bacterial meningitis must be treated immediately with intravenous antibiotics and sometimes corticosteroids. This helps to ensure recovery and reduce the risk of complications, such as brain swelling and seizures. The antibiotic or combination of antibiotics depends on the type of bacteria causing the infection.

As immediate action is needed orally administering antibiotics becomes Ineffective.

Ans) Function of sodium and potassium in the generation of action

As the membrane potential is increased, sodium ion channels open, allowing the entry of sodium ions into the cell. This is followed by the opening of potassium ion channels that permit the exit of potassium ions from the cell. Thus, the cell fires, producing an action potential.
