The cytokines interleukin-1 (IL-1) and tumor necrosis factor alpha (TNFα) are produced by sentinel cells in response to extracel

lular bacteria. They are important for initiating inflammation and the formation of pus. Tissue-resident sentinel cells express pattern recognition receptors that are essential for initiating IL-1 and TNFα signaling.What is the likely localization of these pattern recognition receptors within or on sentinel cells?

Answer:

Cell membrane.

Explanation:

Cytokines may be defined as the small molecules that plays an important role in the cell signalling as well as in the immune system as well. They are made of the peptides.

Pattern recognition receptor are important molecules that plays an important role in the innate immunity. These receptors are present on the surface of the cells like macrophages and monocytes. These receptors are made of the proteins and cannot pass the lipid bilayer. Hence, these receptors are located on the surface of the cell membrane.

Thus, the answer is cell membrane.

Which of the following is responsible for muscle relaxation?
Cloud [144]

Answer:

Option-C

Explanation:

The process of muscle contraction and relaxation is very complex and involves the electrical signals, calcium ions, ATP, proteins- actin, myosin, troponin, tropomyosin, and many others.

The process of muscle contraction begins when the neural signals lead to the release of the sarcoplasmic calcium ions and then calcium binds to troponin and allows the binding of the tropomyosin and formation of cross-bridge.

The muscle relaxes when the signals from the brain stop the release of the calcium ions from the sarcoplasmic reticulum and the released ions are pumped back in the reticulum.

Thus, Option-C is the correct answer.

<h2>Upper limb,Pectorial girdle and Axial skeleton</h2>

Explanation:

Upper limb-

  • The muscles of the upper appendage can be divided  into 6 distinct areas such as <em>pectoral, shoulder, upper arm, front lower arm</em>, <em>back lower arm, and the hand</em>
  • There are 4 muscles of the pectoral locale <em>pectoralis major, pectoralis minor, serratus foremost and subclavius  </em>

Pectorial girdle-

  • The <em>shoulder </em>girdle <em>or pectoral </em>girdle is the arrangement of bones in the attached skeleton which interfaces with the arm on each side
  • In many of the it comprises of the <em>scapula and clavicle</em>
  • In many <em>species  have three bone found in the shoulder, it connected of the coracoid and clavicle   and scapula</em>

Axial skeleton function-

  • The pivotal skeleton underpins and ensures the <em>mind, spinal rope and huge numbers of the interior organs</em>
  • It likewise gives locales to the connection of different bones and muscles in the body and shields the nerves and veins from the <em>cerebrum and spinal line.</em>
