What is medulla oblongata ?

  • Medulla oblongata, also called medulla, the lowest part of the brain and the lowest portion of the brainstem.
  • The medulla oblongata is connected by the pons to the midbrain and is continuous posteriorly with the spinal cord, with which it merges at the opening (foramen magnum) at the base of the skull.
  • The medulla oblongata plays a critical role in transmitting signals between the spinal cord and the higher parts of the brain and in controlling autonomic activities, such as heartbeat and respiration
  • The medulla is divided into two main parts: the ventral medulla (the frontal portion) and the dorsal medulla (the rear portion; also known as the tegmentum).
  • The ventral medulla contains a pair of triangular structures called pyramids, within which lie the pyramidal tracts.
  • The pyramidal tracts are made up of the corticospinal tract (running from the cerebral cortex to the spinal cord) and the corticobulbar tract (running from the motor cortex of the frontal lobe to the cranial nerves in the brainstem)

vodomira [7]

Answer:

This question lacks options, options are:

A.They maintain the cell’s shape.

B.They regulate cell processes.

C.They protect the body from infectious agents.

D.They signal the immune system to destroy pathogens.

E.They speed up biochemical reactions.

F.They send electrical signals.

The correct answers are C and D.

Explanation:

B cells and T cells use different biological weapons to attack the pathogen. The first secrete proteins called antibodies, which are distributed via the blood or the exposed surfaces to the environment, such as mucous. Antibodies are glycoproteins that circulate in the bloodstream looking for antigens that cause some type of damage to the body. Antibodies recognize and neutralize pathogens in a highly efficient way. Once the antibodies are produced, they remain circulating in the bloodstream for several months, which generates immunity for a long period of time to a certain antigen, in other words, they are capable of recognizing other molecules (antigens) in a very specific way and forming stable complexes with them (immune complexes). Its appearance in plasma is part of the adaptive immune response, in what is known as a specific humoral response, constituting a very effective defense against pathogens.
