Regeneration, Aging & Disorders

This module focuses on Regeneration, Aging & Disorders within Anatomy & Physiology I — Cell Division, Tissues & Skin. The module concentrates on Aging and If a cell. Learners move through Regeneration, Aging & Disorders. Key topics include Aging is accompanied by motor neuron attrition and reinnervation failure, If a cell is damaged to a greater extent than can be repaired by satellite cells, the muscle fibers are replaced by scar tissue in a process called fibrosis, and Smooth muscle tissue can regenerate from a type of stem cell called a pericyte, which is found in some small blood vessels.
