The Haversian System

| - osteoblasts begin to replace the fibrocartilage splint with spongy and compact bone, forming a bulge that is initially wider than the original bony shaft

Compact bone contains Haversian Systems, which are in concentric circles called lamellae. Haversian system contains a blood supply and the periosteum is located on the outside

The skeletal system is made up of cartilage and bone. Both bone and cartilage are connective tissues, that is, they are composed of cells in a matrix with intracellular fibers. Just imagine connective tissue as a gelatin salad with grapes and coconut. The grapes would represent cells, the gelatin the support material for matrix, and the pieces of coconut the intracellular fibers. By changing the amounts of each ingredient and adding extra substances, we can produce a material that is very hard like bone and can withstand weight or softer like cartilage which can be used as a cushioning material.

Osteoblast- cells which build bone by removing calcium and phosphates form the blood in the presence of the enzymes alkaline phosphates secrete by

In this exercise, we will examine a fresh raw chicken bone to study bone

The bony collar of long bones helps them withstand compressive stress by the mechanism described in #4A above (i.e. hydroxyapatite, weight-bearing pillars). In addition, long bones also withstand compressive forces by virtue of the spongy ("cancellous") bone in the epiphyses. The interlocking network of bony plates (called "trabeculae") found in spongy bone help to distribute the weight of the body out to the tough bony collar of the diaphysis. In this way, bony plates act much like the trusses or struts in old-time railroad bridges which distribute the weight of the train evenly over the entire bridge.

Honestly, my initial reaction to the minerva meetings was that I was surprised about the meetings because I really did not see the point in just voting for events.The very first meeting was where many people people came and a lot of upperclassmen came as well and they were the ones who mostly introduced the events and I did not know a whole lot about the minerva system. Initially, the meaning of minerva houses is oblivious to most incoming freshman and I realized this when I was helping out as a student ambassador for Union College and asking the families if they had any questions about this college and most of the families wanted to know more about the minerva system as this a concept

Bone remodeling This is where the body replaces old bone with new bone. The woven bone is replaced by lamellar bone. Osteoclasts remove small bone fragments and osteoblasts deposit spongy bone, converting it to compact

From the days of Still we are reminded that structure and function are a primary focus reciprocally interrelated-so much so that the basic structure of the skeleton and the parts that make it up are designed to operate a certain mechanical way. The physiological and deeper functional

This system is made of bones which are composed mainly of collagen, a protein that is woven into a flexible framework,Bone also contains calcium phosphate and calcium carbonate, minerals that add strength and harden the framework. The combination of calcium and collagen gives the bone its strength and flexibility. This system provides support, movement, protection, blood cell production, calcium storage and endocrine regulation .

Ossification is the process of bone formation that is usually beginning at particular centers in each prospective bone and involving the activities of species osteoblasts that segregate and deposit inorganic bone substance about themselves (Webster, 2013). To form fracture callus, hyaline cartilage and woven bone has to be formed first. In order this to happen, chondroblasts and osteoblasts will arise from periosteum of each ends respectively.

He initially determined the cellular sequence of bone remodelling as endothelial cells, intermediate cells, osteoblasts, osteocytes and osteoclast and that the capillary-sinusoid vessel acts as the initial framework on which this process rests. This study showed that the endothelium of the capillary system houses the cells responsible for bone formation.

Bone at the tissue level undergoes remodeling: it is continuously being resorbed and rebuilt (or formed). A negative balance between bone resorption and formation, frequently due to excessive resorption, is the basis of many bone diseases.

The skeletal system is made up of bones and joints. Bones are a dry dense tissue that is composed of calcium phosphorous and organic matter. The bones are protected and covered by a layer of fibrous connective tissue membrane called the periosteum (Brown, et al., 2015, p. 1547). There are two basic types of bone tissue: Compact Bone and Spongy Bone. Compact bones are dense smooth bones, while Spongy bones are composed of small needle-like pieces of bones and open space. Bones are then categorised according to the shape of the bone into four groups: long, short, flat and irregular. Long bones characteristically are typically longer then they are wide and generally have a shaft with heads at either ends e.g. the humerus. They are mainly compact bones. Short bones

The skeletal system includes the osseous tissues of the body and the connective tissues that stabilize or interconnect the individual bones. The bone is a dynamic tissue. Throughout the lifespan, bone adjusts to the physiologic and mechanical demands placed on it by the processes of growth and remodeling.
