2. One way bones are classified is by 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 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 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.
Bones possess five important functions including, support, protection, movement, storage and blood cell formation (Marieb, 2012). Bones protect and support the body by acting as a rigid framework surrounding delicate organs and tolerating enormous pressure when weight bearing and moving (Marieb, 2012). Bones are also responsible for storing fat, minerals and producing blood cells (hematopoiesis) within the cavities of bone marrow (McCance & Huether, 2014) (Marieb,
During the later years, osteoporosis becomes apparent but develops a lot earlier without any warning. The bone has two compartments, which include the cortical bone and the trabecular bone. The cortical bone is the very dense bone tissue that forms the outer shell, whereas the trabecular bone is the
Osteoclasts are bone-absorbing cells that breakdown bone and assist in depositing calcium and phosphate in the blood.
There are approximately two hundred six bones in our body and they're essential in our life. Bones consists of osseous tissue, nervous tissue, and epithelial and muscle tissue. Examples are the femur, humerus, clavicle, and sternum. The bones have many different functions in our bodies, but basically, their main functions are to provide support and protection for the body. Bones provide a framework that supports our body and bones such as skull, vertebrae and rib cage try to prevent internal organs from injuries. Also, bones enable movement by providing points of attachment for muscles and they produce blood cells, also known as hematopoiesis in the red marrow. Lastly, bones store minerals, such as calcium and phosphorus for different cellular activities and store lipids in adipose cells of the yellow marrow as an energy reservoir. There are different shapes and textures of bones. Bones can be flat, such as scapula and sternum, or irregular like the sphenoid bone and vertebra. Also, bones can be short or long. Examples of short bones are the carpal bone and talus and long bones are ulna, femur, and radius. In terms of texture, bones can be compact or spongy. Compact bones are dense and heavy while spongy bones are porous and light. Both types of bones are connective tissues. Usually compact bones are the out layer of a bone and spongy bones are the internal portion of the bone.
2. What are the roles of osteoclasts in bone formation? Osteoclasts are large cells that function to reabsorb, or to digest bone tissue. They digest bone tissue from the inner sides of bones thus enlarging the inner bone cavity so that the bone does not become overly thick and heavy.
The bone consists of the diaphysis and epiphysis. The diaphysis is the middle part of the bone and the diaphysis are the ends of all long bones like for example the hip bone. This structure only qualifies for all typical long bones in our bodies. In this disease of osteoporosis cells of bone tissues are also involved such as osteoblasts, and osteoclasts. Osteoblasts are involved in bone forming cells and they secrete calcium and binding proteins. Osteoclasts are involved in dissolving a damage bone and is a way that the bone can be repaired.
Bone Bone tissue is hard and has a calcified matrix (where the pores are filled with calcium) containing collagen fibers; osteocytes (mature bone cells) lie in the lacunae (cavity containing bone cells). The key functions of bone tissues are: support and protect the body structure and provide cavities for fat storage and synthesis of blood cells. Because the matrix of bone tissue is hard and rigid, the tissue is able to provide support and protection to the
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
Bones contain collagen (protein), calcium salts and other minerals. Each bone is made up of a thick outer shell known as cortical bone and a strong inner mesh of trabecular bone which looks like a honeycomb. Bone is alive and constantly changing throughout life. Old, worn out bone is broken down by cells called osteoclasts and replaced by bone building cells called osteoblasts. In childhood, osteoblasts work faster, enabling the skeleton to increase in size, density and strength. During this period of rapid bone growth, it takes the skeleton just two years to completely renew itself. In adults this process takes seven to ten years.
Bone Lit Review Introduction - Skeletal bone is a dynamic tissue structure that constantly undergoes changes and remodeling throughout someone’s lifespan. Skeletal bones is a mechanical support for locomotion and protecting the organs. Muscle tendons and ligaments insert onto the bone. It is only present in vertebrates. - Bone tissue is made

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
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
