Compare and contrast the three types of muscles, namely, skeletal, smooth and cardiac? A. We can consciously control skeletal muscle but not smooth muscles. Smooth muscles contracts slowly, whereas skeletal muscles contains both slow-twitch and fast twitch bundles. Cardiac muscle is found only in the heart, the other can be found throughout the body.
A&P Basics 1. Which of the following disciplines is MOST likely to concentrate on the structure and function of organelles? a. Gross anatomy b. Histology c. Cytology d. Embryology Which of the following disciplines is LEAST likely to require the use of a microscope? a.
What is a tendon made of? Tendons are made of dense, regular connective tissue. This form of connective tissue consists of densely packed bundles of collagen fibres. These fibres all run parallel to each other in the direction of the pull that is generated on the tendon What are agonistic muscles? Agonistic muscles are a classification used to describe a muscle that causes specific movement or possibly several movements to occur through the process of its own contraction.
Main tissues in the body There are four different types of tissue in the body, these are muscle, connective, nervous and epithelial; and for each type of tissue there are several sub-categories. In this essay I am going to describe the function of each type of tissue and the sub-categories. Muscle The muscle tissue has three different sub-categories which are striated, non-striated and cardiac. The muscle tissue is made up of muscle fibres, which can shorten, contracting and then returning to the pervious shape, which is known as relaxing. These movements cause the blood and other materials like urine, faeces and food, soft tissue and skeleton to move.
Stratified epithelial cells consist of two or more layers of epithelial cells. They are found found in areas where most of the wear and tear of the body takes place. Our body contains four different membranes (physical barriers), each with a specific function. Understanding their different roles and functions, please describe what you think would happen to the body if each was damaged? If each membrane is damaged, the epithelium would not be able to be held up.
[TYPE THE COMPANY NAME] DIFFERENCE BETWEEN THREE MUSCLE TYPES SKELETOL, SMOOTH AND CARDIAC MUSCLE ... GAOLATLHE THABISO KWENAMORE 24 SEPTEMBER 201101827 BIO 231 INTRODUCTION Muscles are multicellular contractile units. They are divided into three types which are skeletal muscle, smooth muscle and cardiac muscle and classification is done according to their structure, location and their function (Tortora and Derrickson,2011). Skeletal muscle is mainly responsible for the movement of the skeleton, but is also found in organs such as the globe of the eye and the tongue. It is a voluntary muscle, and therefore under conscious control, skeletal muscle is specialized for rapid and forceful contraction of short duration (Bevan et al,1996). In describing the cellular components of skeletal muscle, several specialized terms are used such as the plasma membrane of skeletal muscle is called the sarcolemma; its cytoplasm is known as sarcoplasm; the endoplasmic reticulum is called the sarcoplasmic reticulum.
Classification of Tissues Objective: The purpose of this lab exercise is was that know the various tissues found in the human body, and to familiarize myself with their composition and function. I learned that the four primary tissue types in the human body are epithelium, connective tissue, nervous tissue, and muscle tissue. These tissues have unique structures, patterns, and functions. I identified the subcategories of the tissues using a compound light microscope. I had to list the general functions and structural characteristics of the primary tissues.
Provide physical protection Control permeability Provide sensation Produce specialized secretions There are various specialized types of epithelia. They can be sorted by cell shape and the number of cells between the basement membrane and the exposed surface of the epithelium. The three basic shapes of epithelial are squamous, cuboidal, and columnar. If the basement membrane is only covered by one layer of cells it is called a simple epithelium. If the basement membrane is cover by several layers of cells it is called stratified epithelium.

3 Role in disease 4 Diagnostic investigation 5 Other websites [change] Histology (The cells in the salivary gland) There are two types of epithelial cells in salivary glands. They make either mucous or serous secretions. The parotid gland makes serous secretions. The submandibular and submaxillary glands have both types of cells. They make a mixture of mucous and serous.
