The skin is the largest organ of the body. On the average person‚ the skin is approximately 3000 square inches and weighs approximately seven pounds. While the eyes are the “windows of the soul”‚ the skin is the “window to the body” because it is the only organ that can be seen. The skin contains 25% of the body’s blood supply‚ which flow completely through the skin once every minute. The skin is the body’s largest organ of immunity. It is the body’s first line of defence‚ the boundary where

10.1 OVERVIEW OF MUSCULAR TISSUE Types of muscular tissue There are 3 types of muscular tissue: skeletal‚ cardiac‚ & smooth. All 3 may share some things but they differ from one another in their microscopic anatomy‚ location‚ & how they are controlled by the nervous and endocrine systems Skeletal muscle tissue function of most is to move bones of the skeleton (are few that attach to other structures ex--the skin). Muscle tissue is striated b/c alternating light and dark protein bands (striations)

A patient is admitted for electroconvulsive treatment (ECT). The physician orders the neuromuscular blocking agent metocurine iodide (metubine) to reduce trauma by relaxing skeletal muscles. Explain the process of muscle contraction and how a neuromuscular blocking agent‚ such as metubine‚ would interfere with muscle contraction. According to the Mayo Clinic website electroconvulsive treatment is the use of an electrical signal that sent through the brain to intentionally induce a brief seizure
