Muscle Test #1 Study Guide 1. What are the primary functions of muscles? What are skeletal muscles made of? Five Skeletal Muscle Functions 1.Produce movement of the skeleton •By pulling on tendons that then move bones 2.Maintain posture and body position 3.Support soft tissues •With the muscles of the abdominal wall and the pelvic floor 4.Guard entrances and exits •In the form of sphincters 5.Maintain body temperature •When contraction occurs‚ energy is used and converted to heat

How long is the latent period? _2.78_ msec What occurs in the muscle during this apparent lack of activity? The muscle is reacting internally and getting the signals to contract.

types of muscle skeletal which are voluntary‚ smooth muscle which are involuntary and cardiac muscle. Muscle is made up of protein filaments‚ myosin and actin. These filaments slide past each other to produce a contraction which changes both the length and shape of the cell. The primary function of the muscle is to produce both movement and force. Skeletal muscle is composed of bundles of muscle fibres containing myofibrils of thick and thin filaments (myosin and actin). Skeletal muscle have distinct

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)

1 Histology is the study of tissues: in our case‚ it means study of tissues which make up the human body. Tissue is defined as a group of cells which perform a common function. All the cells in a given tissue are not necessarily identical or similar e.g. blood is a type of connective tissue but it has many different types of cells. However‚ tissue also contains two other components i.e. ground substance (or matrix) and fibres. Despite the complexity of the human body and the diversity of organs

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
