Bone tissue also known as osseous tissue serves to protect and support. According to Elaine Marieb and Katja Hoehn’s book (2016) bones have seven important functions which are: support for organs; protection for the brain, spinal cord, and vital organs; movement of the body; mineral and growth storage such as calcium and phosphate; body cell formation such as blood cell formation (hematopoiesis); triglyceride (fat) storage which is then used as an energy source; and hormone production such as osteocalcin. There are different shapes of bones like long bones, short bones, flat bones, and irregular bones. Long bones are bones that are longer in length than in width while short bones are bones that are shaped somewhat like a cube. Flat bones are bones that are flat and thin while irregular bones are differently shaped bones with no specific shape. All the bones in the human skeleton are also separated by location. The axial skeleton consists of the rib cage, vertebral column, and the skull which in all, forms the long axis of the body. The appendicular on the other hand, consists of the limbs, pectoral girdle, and pelvic girdle. The bone also consists of two layers, which are the compact bone and spongy bone. Compact bone is the outer layer which is smooth and solid while the spongy bone, the inner layer has the appearance of a “honeycomb”.
Furthermore, there are five major cell types of bone tissue. Those five cell types are osteogenic cells, osteoblasts, osteocytes,
Our bone tissues are made of a much harder substance than the cartilage, but they can be worn away by friction. They are tough on the outside, but on the inside they have a sponge-like design that helps to reduce the weight while retaining strength. They are designed to maintain the body’s structure and support the body’s movement and are used to protect weaker tissues, such as the brain, lungs and heart.
A long bone is composed of 6 main parts. The diaphysis, epiphyses, metaphyses, articular cartliage, the periosteum and medullary cavity. (Tortora and Derrickson, 2011).
It also protect soft internal organs for an example brain and heart from injury. Skeleton with muscle is strong bones that can enable the body to move freely. Individuals who is at increase risk for fractures may be difficult to heal because of the weakened bones. This can lead to loss of mobility, the inability to retain independent living and even death. Osteoporosis can gives a huge effect to human skeletal due to decreased mineralization of the bone. Human skeletal consist of two types of bones which is compact bones and spongy bones. Compact bones is a bone that has a solid outer surface while spongy bone is inner bone that less dense than compact bone which has many holes like sponge. A spongy bone does not have osteon.The matrix forms an open network of trabeculae. Healthy bone is dense enough to support and protect body and to handle stresses of movement and minor injuries while osteoporosis has abnormally thin bones with larger holes on spongy
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
Bones- provide support and keep shape, they undergo growth and development, Bones have an outer membrane, beneath the outer membrane is compact bone in which canals run through. The canals carry nerves and blood vessels to living cells inside the bone. Inside compact bone is spongy bone. Spongy bone is also found at the ends of bones. In the spaces of bone you will find bone marrow. There is red and yellow bone marrow. The red bone marrow produces
? During fetal development, the bones of the fetus are composed of cartilaginous tissue it resembles osseous tissue but is more flexible and dense because of the lack of calcium salts in its intercellular spaces .As the embryo develops, the process of depositing calcium salts in the soft, cartilaginous tissue occurs and continues throughout the life on the individual after birth.
There are two types of bone in the human body; Cortical bone is dense and compact, forms the outer layer of the bone and the trabecular bone forms the inner layer of the bone and is known as spongy bone (National Library of Medicine, 2016).
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.
Osseous tissue contains specialized cells, cell products, and a fluid matrix. The distinctive solid, stony nature of bone results from the deposition of calcium salts within the matrix. Crystals of calcium phosphate account for almost two-thirds of the weight of the bone. The majority of
Introduction A bone tissue is a specialized connective tissue that exhibit four types of cell that are osteoblasts, bone lining cell, osteocytes and osteoclacts (Rinaldo Florencio-Silva, 2015). It is a composite structure that consisting of inorganic mineral crystal which are mainly calcium and phosphate, an extracellular matrix, cell lipid and water (A.L Boskey, 2010). Calcium and phosphate make up approximately 60% to 70% of the dry weight which give bone it solid consistency, water accounts for 5% to 8% and the organic matrix makes remainder of the tissue (Margrate Nordin, 2001). There are two primary types of human mature bone that are cancellous bone and cortical bone (Oatis, 2009). Cortical bone also called as compact bone which is hard and dense.
Now a days there are hundreds of shows on television that can make sinking into the couch for a weekend bender truly difficult. You can usually tell by the first ten or twenty minutes if it is a show you want to invest your time into or not. Finding your favorite genre seems to help when making this decision from the array of shows available. Due to this show being in its final season I found it only fitting to explain why the criminal and forensic drama known as Bones is an all-time favorite of mine. Bones is an entertaining spin on forensic science shown on Fox. One of the more suspenseful episodes in this series was The Grave Digger episode where Dr. Temperance Brennen and Dr. Jack Hodgins
techniques are also used in order to estimate quantitative parameters and assess tissue properties. Advantages of US methods can be related primarily to the fact that they do not cause radiation exposure. In addition, US devices have the advantages of small size and portabil¬ity providing quick and simple measurements In addition, low costs and shorter investigation times compared with both DXA and QCT (43).

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. In this exercise, we will examine a fresh raw chicken bone to study bone
Have you ever thought about how humans would be without bones? They would not be able to function the way that they do now if it did not have bones. The skeletal system is a highly important system in the human body, it functions as support, protection, and creation of red blood cells. This system is composed of bones and joints, an average adult contains 206 bone and an average child contains 270 bones because as a person grows the bones fuse together to create a single bone. The skeletal system is divided in to two major category: the axial skeleton and the appendicular skeleton. The axial skeleton has 80 bones in the midline axis which contains the bones of the head and the trunk; while the appendicular axis has 126 bones which include the bones from the limbs, pectoral and pelvic regions. There are only a few select bones that are mainly affected by the Paget disease these include the pelvis and the tibia which belong to the appendicular axis; however, other bones that could be affected are the femur, spine, skull, clavicle, and fibula.
