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.
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
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
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
A long bone is composed of 6 main parts. The diaphysis, epiphyses, metaphyses, articular cartliage, the periosteum and medullary cavity. (Tortora and Derrickson, 2011).
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,
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.
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 human body is made up of various bones; in total a person can have up to 206 bones ones the person has reached the adulthood. The skeleton is made up of two different groups which are the axial and appendicular skeleton. Both contain different bones in the body. The axial protects other parts of the body and appendicular skeleton helps the body with motion. Bones can come in different sizes and shapes. Along there are some bones called long bones, some short bones, others are flat bones and last there are what people call the irregular bones. The long bones contain two ends and they are considered longer then wider in cases. The short bones are shaped similar to square shapes but not exactly some bones examples can be 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
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 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
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
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.
