Which diagnostic test is used for the direct visualization of ligaments, menisci, and articular surfaces of joints?

Sati [7]

Arthroscopy is done for direct visualization of the ligaments, menisci, and articular surfaces of the joints. Thus, option A is correct.

<h3>What is the role of ligament?</h3>

Ligaments are type of connective tissue which help to connect bones, joints and organs. It provide support internal parts of the body.

It is made of a band of connective tissue, collagenous fibre and spindle-shaped fibrocytes which is an elastic fibers.

Ligaments holds bones together, stabilize it, provide strength to joints etc.

By the use of Arthroscopy doctors can diagnose and treat the joint’s structural problems like any dysfunction. Hence, Option A is correct.

Many motor and sensory functions are primarily controlled by the:

GalinKa [24]

<span>Many of the sensory and motor functions are controlled by the central nervous system and the brain. An example of this would be grabbing a hot pot from the stove. Your brain sends a signal to your hand to tell it to grab the pot. When you grab it your sensory nerves detect that the pot is hot and is burning your hand. The signal it sends back to the brain is one that there is pain and to release the pot.</span>

Select the five major mechanisms of antimicrobial resistance. Check All That Apply

Rudik [331]

Answer:

All the given statements are correct except b.

Antimicrobial resistance (AMR) refers to the ability of a microorganism to grow in the presence of drug or a chemical that would normally limit its growth or kill it.

It makes it difficult for the existing drugs to eliminate the infection as they become less effective against the microbe.

There are five major mechanisms by which a microbe attains resistance against antimicrobial chemical or drug:

Drug modification or inactivation: A microbial enzyme inactivates the antimicrobial agent. For example, few bacteria produce β-lactamases which provide multi-resistance against β-lactam antibiotics such as penicillin, cephalosporin etc.
Alteration or modification of target site: An altered target site prevents the antimicrobial agent from binding to its target. For example, alteration of penicillin binding protein (PBP) in Methicillin-resistant <em>Staphylococcus aureus </em>(MRSA).
Alteration of metabolic pathway: The microbe uses an alternative pathway to circumvent the blocked pathway. For example, sulfonamides-resistant bacteria started using preformed folic acid in place of para-aminobenzoic acid (PABA).
Decreased drug accumulation: Microbial efflux pumps remove the antimicrobial agent (before it could do any damage) by pumping it out of the cell.
Decrease in cell permeability: The permeability of the microbial envelope to the antimicrobial agent is decreased
