Advantages of using nose hair trimmers over scissors Nose hairs main function is to stop dirt from entering your body. But they become a nuisance when they grow too long and start protruding through the nose, thereby affecting your appearance. The Best Nose Hair Trimmer will do a good job of maintaining the length of your nose hair. It will not remove all the hairs but trim just the hairs that can be seen. Scissors have to be handled carefully to avoid the risk of injuring the nose. Whereas, nose

Chapter 1 The Human Body: An Orientation Multiple Choice The correct sequence of levels forming the structural hierarchy is (c) Chemical, cellular, tissue, organ, organ system, organismal The structural and functional unit of life is (a) cell Which of the following is a major functional characteristic of all organisms? (e) all of these Two of these organ systems bear the major responsibility for ensuring homeostasis of the internal

An Overview of Anatomy Exercise 1: Anatomical Position QUESTION: A. Explain why it is important to have a universally accepted anatomical position when studying the structure of humans. Having a universally accepted anatomical positional is important to avoid confusion. It creates a reference point so that no matter language or background of different people, they can still communicate efficiently. Exercise 2: Surface Anatomy A. Review Figure 3. Complete the table by placing

“How much do a mouthful of implants cost?”. “How much does each tooth cost?” (It is assumed that you need an implant for every tooth, which usually isn’t true) “How much will it cost to have all my teeth out and implants put in?” “Why do implants cost so much?” Every patient has the right to know what the total treatment will cost and how much they are responsible for. In order to provide this information, the dentist has to know exactly what the treatment is. When someone that has

Task 1 – Bones and Connective Tissue 1.1 Explain the structure and composition of bone tissue A long bone is composed of 6 main parts. The diaphysis, epiphyses, metaphyses, articular cartliage, the periosteum and medullary cavity. (Tortora and Derrickson, 2011). The epiphyses are the proximal and distal ends of a bone that consists mainly of spongy bone. (Tortora and Derrickson, 2011). Originally the epiphyses are separated from the diaphysis by a layer of cartilage that later fuses together

the shaft enlarge. Nutrients can no longer diffuse once the matrix becomes sufficiently calcified and the chondrocytes subsequently die. This creates cavities within the bone. Elsewhere, the cartilage remains healthy and continues to grow briskly, causing the model to elongate. During the third stage which is in month 3, the forming cavities are invaded by a collection of elements called the periostial bud, which contains a nutrient artery and vein, lymphatic vessels, nerve fibers, red marrow

Canine bone development and developmental bone diseases are of growing interest to researchers and consumers. In order to produce healthier canines and to reduce the incidence of diseases commonly found in canines, it is important to understand what bone development is and how it occurs, factors that influence bone development, and developmental diseases. Development can be defined as a series of changes that takes place in an animal beginning in the embryonic state and lasting until maturity. These

Chapter 5: The Skeletal System I. Introduction. The skeletal system consists of the bones, along with the cartilage and fibrous connective tissue that make up the ligaments that connect bones to bone at joints. A. Functions of the Skeleton. 1. The skeleton supports the body. 2. The skeleton protect soft body parts. The skull protects the brain, the rib cage protects the heart and lungs, and the vertebrae protect the spinal cord. 3. The skeleton produces blood cells. Red bone marrow contains

There are a wide variety of cancers affecting people and their loved ones everyday such as breast, lung, brain, and skin cancer just to name a few. Bone cancer is a rare type of cancer not talked about quite as often, but it still affects a large number of people. It is important to learn about bone cancer and its many manifestations in order to make quicker diagnoses and hopefully move closer towards finding a cure. The first step in becoming familiar with bone cancer is to understand what bones

vertebral body c. Proximal Closer to the origin of the body. In this case the fracture at the proximal diaphysis means the part of the shaft closer to the origin of the humerus (the shoulder) d. Diaphysis The shaft of the bone which surrounds the medullary cavity. In this patients case the diaphysis (shaft) of the humerus has been fractured 
 2. One way bones are classified is by
