Muscle tissue Muscle tissue has a ability to relax and contrast and so bring about movement and mechanical work in various parts of the body. There are other movements in the body too which are necessary for the survival of the organism such as the heart beat and the movements of the alimentary canal. Muscles can be divided into three main groups according to their structure * Smooth muscle tissue. * Skeletal muscle tissue. * Cardiac (heart) muscle tissue.

Muscle Tissue 1. How is muscle tissue categorized? Muscle tissue is categorized by its shape‚ the number of nuclei‚ and the mechanism of stimulation. 2. a. Click the Smooth Muscle Tissue. Identify each of the following: Nucleus----- Smooth Fiber Muscle------------------ b. Describe smooth muscle control (voluntary or involuntary). Involuntary c. Name some smooth muscle functions (click the “Tissue Locations” button). Smooth

Enzymes All enzymes are globular proteins and round in shape They have the suffix "-ase" Intracellular enzymes are found inside the cell Extracellular enzymes act outside the cell (e.g. digestive enzymes) Enzymes are catalysts → speed up chemical reactions Reduce activation energy required to start a reaction between molecules Substrates (reactants) are converted into products Reaction may not take place in absence of enzymes (each enzyme has a specific catalytic action) Enzymes catalyse

Classification of Tissues Introduction Cells are the smallest units of life. In complex organisms‚ cells group together with one another based on similar structure and function to form tissues .Tissues provide the numerous functions of organs necessary to maintain biological life. This lab exercise seeks to introduce the various tissues found in the human body and to familiarize you with their composition and function. The study of tissues is called histology ‚ and is important to the understanding

Muscle Tissue Introduction * Motion * Results from alternating contraction (shortening) and relaxation of muscles * Skeletal system * Provides leverage and a supportive framework for this movement * Myology – study of muscles Muscle Tissue * Alternating contraction and relaxation of cells * Chemical energy changed into mechanical energy Types of Muscle Tissue * Skeletal muscle – primarily attached to bones * Striated and voluntary * Cardiac

Epithelial Tissue covers body surfaces (epi‚ on + thelium‚ surface). Epithelial tissue consists of cells attached to one another to form an uninterrupted layer of cells that separates the underlying tissues from the outside world. The body’s epithelium not only covers its obvious surfaces (such as the epidermis of the skin and the linings of respiratory‚ urinary‚ and digestive tracts) but also extends into all of the complex invaginations which form lungs‚ kidneys‚ sweat glands‚ digestive glands

Role and Functions of Law Introduction Over time man has evolved from an uncivilized primate to a technological driven working machine‚ but that evolution could not have occurred without law. Law gives the backbone a society needs to flourish in a civilized and more or less positive way. Although laws in most societies are not perfect‚ they keep society members in check and prevent chaos from running amok. In this paper I will discuss the major roles and functions of law will be discussed including

Chapter 6 Ossecous Tissue and Skeletal Structure The Skeletal system consists of bones and their associated connective tissues‚ including cartilage‚ tendon and ligaments. I. Function of the Skeletal System 1) Bone- The most rigid component of skeletal system a) Support- serves as a framework; Maintains body’s shape b) Protection- of critical internal organs‚ brain‚ heart and lungs c) Lever System- for muscles to produce body movements d) Mineral storage- e.g. Calcium and
