AMYOTROPHIC LATERAL SCLEROSIS - AN EXPLANATION - LESSON 199

ALS is nothing but amyotrophic lateral sclerosis. The other name of this disease is Lou Gehrig's disease. Amyotrophy means muscle wasting caused by disease of the nerves that supply to the muscles.  The cause is unknown yet medically. A- means nothing, myo-means muscle, and -trophy means growth, sclerosis means hardening or thickening. That is a state in which muscle gets hardened or thickened due to no sensation.   Our nervous system is of two types that is Central nervous system and peripheral nervous system (PNS).  Central nervous system includes brain and spinal cord and the nerves associated with it that is integrative and control centers of the body (central and autonomic nerves).  Peripheral nervous system consists of the cranial nerves (nerves that connect eyes, ears, nose, and mouth to the brain) and spinal nerves (nerves connect the brain to the hands and feet).  Peripheral nervous system is an extension of central nervous system, which unites ...

FORMATION OF HUMAN BONES - 2 - LESSON 198

Now in this post we would learn about the remaining part of formation of bones. This Ossification is also called Osteogenesis which is the process of laying down new bone material by cells. Intramembranous ossification involves primitive connective tissue called mesenchyme, while endochondral ossification involves cartilage as a precursor. In most of the fracture, endochondral osteogenesis the most commonly occurring process healing can be done for the long bones which is treated by plaster of paris. Then what is intramembranous ossification? This ossification mainly occurs during formation of the flat bones of the skull but also the mandible, maxilla, and clavicles. Then what is Endochondral ossification? This ossification occurs in long bones and most of the rest of the bones in the body. An initial hyaline cartilage which continues to grow is involved.  Not only are calcium and phosphorous part of the hard structure of bone tissue but calcium is also st...

FORMATION OF HUMAN BONES - LESSON 197

Now in this post we will learn about the formation and structure of bones.  FORMATION OF BONES:  Bones are complete rigid organs, which forms part of the endoskeleton of vertebrates. They are helpful to move, protect, and support the different organs of the body. They also produce red and white blood cells and store minerals. This Bone tissue is a kind of dense connective tissue as bones come in a different shapes and a complex internal and external structure. They are light in weight and yet strong and hard in order to fulfill their many several functions. This connective tissue is also called osseous bony tissue which is helpful for rigidity and a honeycomb-like three-dimensional internal structure. Osseous tissue consists of osteocytes also called bone cells which is surrounded by a hard, intercellular substance filled with calcium salts. During fetal development, the bones of the fetus are composed of cartilage tissue, which resembles osseous tissue and is more fl...

BONE STRUCTURE AND FORMATION - LESSON 196

If you want to learn about FORMATION OF BONES AND THEIR STRUCTURES then read this article all the way to the end. Specifically, I'll cover bones are the rigid organs which are useful to protect, giving shape, and size to the body., The fetus bones when the child is in womb, are mainly composed of cartilage tissue. These tissues are less dense than the osseous tissues.  During ossification or bone formation the immature bony cells called osteoblasts replace the cartilage tissues. Bone tissue is reabsorbed and is digested by large cells called osteoclasts. Bones are the rigid organs which are useful to protect, giving shape, and size to the body. is vital to FORMATION OF BONES AND THEIR STRUCTURES. Because FORMATION OF BONES AND THEIR STRUCTURES couldn't even survive without Bones are the rigid organs which are useful to protect, giving shape, and size to the body.. Bones are mainly calcium deposits which is also called ossification or bone formation Relates to this because...

HUMAN MUSCULOSKELETAL SYSTEM - LESSON 195

In this post we would learn about MUSCULOSKELETAL SYSTEM, The musculoskeletal system is also called as locomotor system, which is helpful to provide form, support, stability, and movement to the body. This system includes bones, muscles, and joints. These are very important so that they have functions in the body.  1. BONES:  Bones give support to the framework around which the body is constructed, protect, and support internal organs. They also assist the body in movement because they are attached with muscles. The hematopoietic tissue, which is also called red bone marrow that manufactures blood cells. But the other parts of bone are very useful to minerals necessary for growth, such as calcium and phosphorous. The skeletal portion of the system serves as the main storage system.   2. MUSCLES: Muscles are attached to bones or to internal organs and blood vessels, and are responsible for motion or movement. These muscle cells contain contractile filaments, whic...
