Answer: The nearby nerve that can be affected by this tumour is the FACIAL NERVE.
Explanation:
As stated in the question, the acoustic neuroma is a tumor that arises from the vestibular portion of the vestibulocochlear nerve which is the VIII ( 8th) cranial nerve.
VESTIBULOCOCHLEAR NERVE: These nerves are composed of two distinct sets of fibres, vestibular nerves and cochlear nerves.
The vestibular nerves arise from the semicircular canals of the inner ear and convey impulses to the cerebellum. They are associated with the maintenance of posture and balance. The cochlear nerves originate in the spiral organ in the inner ear and convey impulses to the hearing areas in the cerebral cortex where sound is perceived.
The Facial nerve, also called the 7th cranial nerve, which are the motor fibres that supply the muscles of facial expression. It lies adjacent to the vestibulocochlear nerve as they pass through the internal auditory canal which is located at the petrous part of the temporal bone. As the tumor grows, the facial nerve would be affected because it's the closest nerve to the VESTIBULOCOCHLEAR nerve..
You can use old pieces of paper as scratch paper, make papier mache, use it as padding for packages, or make origami.
Answer:
Osmosis is a process in which molecules pass from semipermeable membrane.
Explanation:
Osmosis is a biological process. The solvent molecules pass through semipermeable membrane and then solute particles move through the membrane with the help of water. These molecules are not capable of passing through the membrane in absence of water.
Answer:
gene therapy, cloning and genetic engineering
Explanation:
Gene therapy is the replacement of faulty defectie genes with the normal ones aimed at correcting genetic disorders. In somatical gene therapy, genetically modified organisms, e.g., viruses are used to carry the normal gene and introduce it into the affected cells. This is used to treat lung cystic fibrosis.
Cloning is a type of reproduction where a group of cells arise from single individual cells without fertilisation. The nucleus from a fertilised ovum is removed and replaced with a diploid nucleus of a cell from the mammary glands of another sheep.
Genetic engineering deals with identification of desirable genes, altering, isolating and transferring the gene from one living organism to another.
