Whenever a mineral is needed hormone signals are sent to the bones and the mineral that is needed is released into the blood stream. Vitamin D is needed for bones to properly absorb and store these minerals. 2) Flat bones provide extensive surfaces for muscles to attach. Muscles attach to flat bones to help provide movement of the arms and legs. Flat bones provide protection for the internal organs including the brain, heart, lungs, liver and kidneys.
Describe the structure and development of bone and the factors that influence it. Bone is living tissue that makes up the body's skeleton. The bone consists of blood vessels, nerve cells and living bone cells. Bones are made up of calcium, phosphorus, sodium, and other minerals, as well as the protein collagen. Calcium is needed to make bones hard, which allows them to support your weight.
This article provides the details of how bones really heal themselves within the body, and all the different terms for each process. Discussion: I will discuss the details the article provides for each function and process the bone goes through. The main function of bones is to create structure for the body but also the body stores minerals in the compact bone. The red marrow is also used to produce red blood cells and the yellow marrow is used to store fat. Your bones never stop growing or changing, and the three primary cells used in the bone growth process are osteoclasts, osteoblasts, and chondroblasts.
Bodies in Balance The Skeletal System The human skeleton is mostly made up of bones. Bones are composed of four different types of cells, which are referred to as osteogenic (type of stem cells), osteoblast (bone forming cells), osteoclast (bone destructing cells), and osteocytes (transports bone containing essential minerals such as calcium and phosphate into the extracellular matrix). Further, it promotes the production of red blood cells in the bone marrow. The bones articulate at joints. The human body has 206 bones which are organized in the skeleton.
The brain, eyes, heart, lungs and spinal cord are all protected by your skeleton. Your cranium skull protects your brain and eyes, the ribs protect your heart and lungs and your vertebrae spine, backbones protect your spinal cord. Bones provide the structure for muscles to attach so that our bodies are able to move. Tendons are tough inelastic bands that hold attach muscle to bone. There are many differences between the male and female human skeletons.
[2] The skeletal portion of the system serves as the main storage system forcalcium and phosphorus and contains critical components of the hematopoietic system. [3] This system describes how bones are connected to other bones and muscle fibers via connective tissue such as tendons and ligaments. The bones provide the stability to a body in analogy to iron rods in concrete construction. Muscles keep bones in place and also play a role in movement of the bones. To allow motion, different bones are connected by joints.
To analyze bone structure or other hard tissues, the characterization technique X-ray Computed Tomography can be used. However, if higher levels of detail are required then the technique called X-ray Microtomography can be used. Microtomography is a nondestructive three-dimensional imaging technique that uses the penetrating characteristics of X-rays to take cross-sections of small samples, such as bone, teeth, human tissue, polymers, plastics and other materials of interest. The cross sections taken from the material can be used to recreate a virtual model for analysis. While classic X-ray Computed Tomography scans can be used on a human scale, X-ray Microtomography is generally used to model smaller objects for example, a bone biopsy or a tooth.
[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.
Skeletal System * Function of the Skeletal System * Support - framework that supports body and cradles its soft organs * Protection - for delicate organs, heart, lungs, brain * Movement - bones act as levers for muscles * Mineral storage - calcium & phosphate * Blood cell formation – hematopoiesis * Types of Bones * Long Bones - metacarpals, metatarsals, phalanges, humerus, ulna, radius, tibia, fibula * Short Bones - carpals, tarsals * Flat Bones - rib, scapula, skull, sternum * Irregular Bones - vertebrae, some facial bones * Sesamoid – patella * Skeletal Organization 1. Axial Skeleton * skull, ribs, vertebral column 2. Appendicular skeleton - arms, legs, and bones that anchor the limbs to the axial skeleton. * Axial Skeleton 1. Cranium Facial Bones Anterior View Anterior View 2.
Muscle tissue contract to produce active movement. Neural tissues conduct electrical impulses and carries information. The protected regions of our body for example our kidney tubes, the lining of the ventral body cavities and the lining of blood vessels are called simple squamous epithelium, they protect regions in which absorption takes place or where a slippery surface reduces friction. Stratified squamous epithelium protects when there are severe mechanical stresses the lining of the mouth and esophagus are prime examples of the epithelium. I believe that if the cutaneous membrane was damaged it would heal in time after all it is our skin and we know that in most people it heals with the help of red blood cells.
