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)

ASHA 777 [7]

Answer:

There are two alleles, the recessive yellow allele and the dominant brown allele. The female is hom0zygous recessive while the male is heterozygous, this means that half of their children will be hom0zygous recessive and be yellow. The other half will be brown and heterozygous, meaning they have a yellow allele and a brown allele. If the female mated with a hom0zygous dominant male, then all of their offspring will end up being heterozygous and brown.
