Question
choose the one alternative that best completes the statements or answer the question. Which of the following is not a function of the nervous system? A) direct long-term functions, such as growth B) integrate sensory information C) sense the internal and external environments D) control peripheral effectors E) coordinate voluntary and involuntary activities The part of the peripheral nervous system that carries sensory information to the CNS is designated A) efferent. B) autonomic. C) afferent D) motor. E) somatic. Which of the following are a type of glial cell found in the peripheral nervous system? A) microglia B) astrocytes C)ependymal cells D) satellite cells E) oligodendrocytes Functions of astrocytes include all of the following, except A) conducting action potentials. B) forming a three-dimensional framework for the CNS. C)responding to neural tissue damage. D) guiding neuron development. E) maintaining the blood-brain barrier. Small, wandering cells that engulf cell debris and pathogens in the CNS are called A) satellite cells. B) oligodendrocytes. C) astrocytes. D) microglia. E) ependymal cells. Which of the following is not a recognized structural classification for neurons? A) pseudopolar B) anaxonic C) bipolar D) multipolar E) unipolarExplanation / Answer
1. nervous system are the sensory, communicative, integrative and motor functions. Nervous system coordinate the functioning of body and communicates that information to the brain and spinal cord. It does not function in direct long-term function such as growth (a).
2. Motor
3. Satellite: in CNS, glial cells are oligodendrocytes, astrocytes, ependymal cells and microglia while PNS Schwann cells and satellite cells.
4. Astrocytes are the star-shaped glial cells in the brain and spinal cord. They forms blood–brain barrier, provision of nutrients, repair the brain and spinal cord following traumatic injuries, conducting action potential, guiding during neuron development (b).
5. Microglia engulf drbris and pathogen from CNS.
6 Anaxonic
