The skeletal system makes up the framework of our body. Without our skeleton, we would just be piles of organs and muscles with no shape. This system is one of the most important in our bodies because it is the outline that every other system follows. Our skeletal system is like the house that the rest of our systems live in. The skeletal system frames our entire bodies and protects our fragile inner organs. We have two major types of bone in our body: compact bone and spongy bone. Compact bone is dense and looks smooth, while spongy bone is comprised of small needle-like pieces of bone with lots of open spaces. Our body contains 206 bones. The skeleton is separated into axial and appendicular sections. The axial skeleton includes the bones in the longitudinal axis of our body. The appendicular skeleton consists of the limbs and girdles of the body, such as our arms and shoulders. There are four different classifications of bone, determined by their shape. Long bones are shafts with ‘heads’ on both sides. Our limbs contain mostly long bones. Short bones Complete Labeled Skeleton are cubular, and mostly comprised of spongy bone. Wrist and ankle bones are short bones (www2.highlands.edu, The Skeletal System:Macro and Micro Anatomy). Flat bones are usually curved and sandwich spongy bone between two layers of compact bone. These bones can be found in the skull and sternum. …show more content…
All compact bone is made up of cylindrical osteons which are made of concentric rings of matrix called lamellae. Osteons house all the inner workings of bone and the cells within it. Haversian canals run through the hollow middles of osteons and carry blood vessels and nerves into the bone. Running perpendicular to the Haversian canals are Volkmann's canals, “connecting vascular and nerve supplies of periosteum to those in haversian canals and medullary
The bony collar of long bones is the one that is designed to help support the weight of the body and withstand compressive stress.
The three functions of the skeletal system are to support, to allow movement, and to protect. The skeleton is the framework of the body and also cradles its soft organs, with it the body would be just a jelly mass it wouldn’t have no definite shape and would just collapse. It supports the softer tissues and provides points of attachment for more skeletal muscles to hold all of the parts of the body upright. For example, the bones of the legs as pillars to support the body trunk we stand up. It also supports the body against the pull of gravity. The skeletal allows movement. The skeletal muscle attached to the bones by tendons and uses the bones as a simple mechanical lever system to move the body and its parts. All together with the muscles
Bones are dense and provide support and structure to the body. The two types of bones is compact and spongy bones. Compact bones are dense and tough. Spongy bones are not as dense and are flexable. Bone remodeling occurs n 120-day cycles. Over the first 20 days resorption by osteoclasts occurs. Osteoclasts release proteases, clears away damaged bone, and releases matrix-bound growth factors. Bone formation occurs by osteoblasts over the last 100 days. Osteoblasts fill in bone cavity with bone matrix.
The musculoskeletal system offers support and stability for your body so we can properly function and move around. Different types of muscle within the muscular system include cardiac, skeletal, and smooth. The reason our bodies are capable of producing movement is because of the way our muscles contract. Our adult skeletal structure is made up of 206 bones that all differ in shapes and sizes. The composing parts that make up the system include the bones, joints, and muscles that all connect so we’re capable of moving. These components allow for our bodies to maintain a stable structure that can keep us upright. The axial skeleton refers to the skull, the vertebral column which supports the spinal cord, ribs, and sternum. It offers protections
Flat bones – these include Scapula, sternum, cranium, os coxae, pelvis and ribs . Their main function is to provide protection to the body’s vital organs as well as being a base for muscular attachment.
The coccyx is a triangular-shaped bone located in the axial skeleton at the end of the spine and is inferior to the sacrum. This bone is really a set of small of bones (usually four, but could be three or five) that fuse during development. Since it is shaped like a tail, it is generally referred to as the tailbone. I found it fascinating that genetic research found that the same genes that produce the tails of mice also are responsible for the development of the coccyx. If ever there is a point to be made for evolution, the coccyx is it. I bet we were some awesome-looking creatures in ancient times – moving around, twitching our little tails!
With this formation, articular cartilage can be found at the ends of our joints, like our knee, for cushion, and it allows for our joints to move without discomfort. Then we have the inside of our bone, which is hollow and allows for blood vessels to penetrate and provide nutrients. Previously referred to in this letter as spongy bone tissue, this tissue has a lattice-like pattern. What may be easier to think of would be your favorite waffle fries from Chik-Fil-A! It is strong, but not as tough as our other type of bone tissue, compact bone tissue. Compact bone covers the spongy bone and provides a tough exterior for one main function: protection. You can think of compact bone as spongy bone’s protector. This is the outer bone that you felt when you were coating the chicken
Bone is a connective tissue with a hardened matrix that is developed from calcium phosphate deposits. Calcification is the process that creates the hard tissue of bones. They come in various shapes and sizes, from flat bones
Although your teeth are also considered part of your skeletal system, they are not counted as bones. Your teeth consist of enamel and dentin. Enamel is the strongest substance in your body. The main priority of the skeletal system is to provide support for the body. Without bones our body would be in a pile of guts and mush on the floor. Your skeleton furthermore assists to protect your internal organs and fragile body tissues. The brain, eyes, heart, lungs and spinal cord are all sheltered by your
The skeletal system also maintains the structure of the body and is the frame work of its shape. According to Elaine N. Marieb & Katja Hoehn, (2016), “The axial skeleton supports and protects, while the appendicular skeleton allows mobility.”
In this paper I will clarify the relation between the integumentary system and the skeletal system. During this paper I will address how the two systems work together to maintain homeostasis and what occurs when balance is not maintained between the integumentary and skeletal system. During this paper I will explain how osteoporosis is directly linked between both the integumentary and skeletal system and ways to prevent or yield this disease.
Spongy bone, or cancellous bone, is much lighter than compact bone; spongy bone provides the body with support and flexibility. The cancellous bone may turn into compact bone through osteoblasts
Some of the organ systems of the body are the integumentary system, skeletal system, muscular system, nervous system, senses, and endocrine system. They are all equally as important to the survival of the human body. The first organ system that will be discussed is the integumentary system. The main purpose of the integumentary system is protection from infection, harmful rays of the sun, and cuts. Furthermore, the organs found in the integumentary system are the skin, hair, nails, sense receptors, sweat glands, and oil glands. The second organ system is the skeletal system. The skeletal system is made up of a total of 206 bones, 80 bones in the axial skeleton which is the trunk and head, and 126 bones in the appendicular skeleton which is the upper and lower extremities, and pelvis area. In addition, the main duties of the skeletal system are posture, aids muscles in movement, and heat production. The organs fou...
The axial skeleton consists of the skull, hyoid bone, vertebral column, sternum and ribs. The axial skeleton is a vital part of the skeletal structure e.g. bones as it protects the CNS (central nervous system); it also provides attachment of other bones and muscles in the body e.g. arms and legs
There is two divisions of the bones, the axial skeleton and the appendicular skeleton. The axial skeleton consists of 80 bones which include the skull, vertebral column, ribs and sternum. The skull considts of 22 bones. The cranium which cover the brain are made up of 8 bones and the facial is made up of 14 bones.
