Sannu’s Story A. In Sannu’s case why is there both sensory loss and muscle weakness? Leprosy is a disease that has been known since biblical times. It causes skin sores‚ nerve damage‚ and muscle weakness that gets worse over time. Leprosy is caused by the bacterium Mycobacterium leprae. It is not very contagious and it has a long incubation period (time before symptoms appear)‚ which makes it hard to know where or when someone caught the disease. Children are more likely than adults to get the

BIOLOGY 2113 Unit IV Review Guide Chapters 13-17 Chapter 13 – True or False 1. The nervous system consists of the brain‚ spinal cord‚ and nerves. 2. The afferent nervous system consists of all outgoing motor pathways. 4. Ependymal cells engulf and destroy microbes and cellular debris in inflamed or degenerating brain tissue. 5. Oligodendrocytes form myelin sheaths around nerve fibers in the CNS. 6. Nerve fibers with many Schwann cells forming a thick myelin sheath are called myelinated fibers

BIOLOGICAL FOUNDATIONS Heredity Heredity refers to the process of transmitting genetic characteristics from parents to offspring. Physical traits and even physical defects are known to be hereditary. Also‚ some mental traits and mental defects are known to be hereditary.

Part I: Origins of Psychology In psychology there are several perspectives that are used to describe‚ predict‚ and explain human behavior. The three major psychological perspectives are functionalism‚ structuralism‚ and behaviorism. Functionalism stressed the importance of how behavior functions to allow people and animals to adapt to their environments. They included research that involved direct observation of living creatures in their natural settings. They also studied how psychology could be
