The Skeletal System: The Four Major Components

One of the most important parts of the body is the spinal column. It is made up of individual bones called vertebrae. Joints connect all of these individual bones together and ligaments connect to bones to support joints.

The skeletal system, while appearing inert at first glance, is a dynamic organ responsible for a number of vital functions in the body; including but not limited to providing protection and support to other organ systems, as well as permitting movement through collaboration with the muscular system. At the cellular level, bone provides a reservoir of growth factors and cytokines, maintains the acid-base balance and mineral homeostasis, and is the site of hematopoeisis. Like other connective tissue, bone has both a cellular and an extracellular matrix component. The matrix is made up of collagen fibers and noncollagenous proteins, with type I collagen accounting for ~90% of total protein, and the noncollagenous osteocalcin, osteopontin, and bone sialoprotein, and others making up the other 10%. In contrast with other connective tissue, the extracellular matrix of bone is mineralized physiologically, though the deposition of layers of carbonated hydroxyapatite. This mineral component, making up 50-70% of bone, provides bone 's characteristic mechanical rigidity and strength (Clarke 2008). Elasticity and flexibility are due to the organic matrix, which makes up another 20-40%, lending bone incredible resilience without compromising its strength, and another 5-10% of bone is water.

The axial skeleton is part of the skeleton that has bones from the head and the trunk which are found in the vertebrate, it forms the main axis or core of your skeletal system. It has 80 bones and is split into eight parts; the skull bones, the ossicles of the middle ear, the hyoid bone, the rib cage, sternum and the vertebral column. Ity kepps the heart and the lungs safe from any damge that the body might experience. It is also the portion of

Unit 1 principles of anatomy and physiology Describe the structure and function of the skeletal system: The skeletal system consists of the axial skeleton, the appendicular skeleton and many different bones. The axial skeleton is part of the skeleton, it consists of eighty bones; twenty eight in the skull and fifty two in the torso. These bones can be found in the skull bones, the ossicles in the inner ear, the hyoid bone, the rib cage, sternum and the vertebral column.

The chicken leg bone got more bendable and jelly-like because the acid destroyed the calcium in the bone.

Cervical vertebra locates in the neck between occipital bone and T1 vertebra. It helps hold up the skull and protects the spinal cord. Atlas and axis are very special bones because they provide the movements for the head. Atlas is a ring-shaped vertebra that rotates and axis is a pivot that helps the head to turn side to side. Thoracic vertebra has a very important job is to protect the heart and lungs which locates in the trunk between C7 and L1 of the body. Lumbar vertebra is consider as the lower back between T12 and S1 in the body that can helps support the weight of the body. Sacrum and coccyx located in the lower back between L5 and C1. Sacrum is a very tough bone that supports the weight and coccyx, also known as the tail bone, connects with the muscles to the pelvic

There was a lot of information in this week’s reading. Having studied the skeletal system in previous classes, this was quite the refresher. Although I recognized a lot of the terms used to describe bones, it was very interesting to read about the basic anatomy of bones. In my reading of Bowers Chapter 2 page 46, I learned about the three anatomical categories of bone. I also learned about the three gross structures of long bones. In the past, I knew that the thigh bone was called a femur and that it was a long bone. I did not know that as along bone, its three parts were called the diaphysis, metaphysis, and epiphysis. This information was useful when I read the case study. Estimating age based on whether the epiphysis had fused or not was

The skeletal system consists of bones, joints, and associated cartilages. These provide shape and support for the body and protect internal organs and structures. The marrow cavities within some bones serve as the site of hematopoiesis. The also skeleton serves as the reservoir of calcium and phosphorus. A common pathology of the skeletal system is rheumatoid arthritis (RA). It is a chronic systemic disease characterized by autoimmune inflammatory changes in the connective tissue throughout the body. • Celecoxib (Celebrex) is a type of non-steroidal anti-inflammatory drug (NSAID) that will directly target cyclooxygenase-2, COX-2, an enzyme responsible for inflammation and pain. Celecoxib is available in 50 mg, 100mg, 200 mg, and 400 mg capsules.

The skeletal system is one of the most important systems in most living things. The skeletal system consists of 206. It also includes the ligaments, tendons, and cartilage that connect the bones. The ligaments are a piece of connective tissue that connects two bones or cartilages or holds together a joint. Tendons attach the muscle to bone. Cartilage is a connective tissue found in many joints. It performs vital functions of support and movement. It also helps protect, produce blood cells, store calcium, and regulate endocrine.

Worms and humans are more related than you think. The muscular system is responsible for the movement of the human and the worm body. The skeletal system supports and protects the human body. The worm has 2 types of muscles. These 2 muscles are the circular and longitudinal. Humans have 600+ skeletal muscles and they have 3 different type of muscles smooth, skeletal, and hearty. The reason why a worm's muscular system is different than a humans muscular system is because a human has a skeletal system and a worm does not. Worms do not have any skeletal systems and a human has 300 bones. The reason that a worms skeletal system is different than a humans skeletal system is

The three reasons on having and maintaining a healthy skeletal system and the ways I am going to do that. Like exercising, eating healthy, and Vitamin D. With these ways I can have and live a healthier life for me when I am going to old.

Chapter seven educated us about the axial skeleton. According to our textbook, the axial skeleton has 80 bones. Our book divided these 80 bones into, the skull, which is subdivided into 18 cranial bones and 14 facial bones; bones associated with the skull, which are 6 auditory ossicles and the hyoid bone; the vertebral column subdivided into 24 vertebrae, the sacrum and the coccyx and the thoracic cage, which are 24

The musculoskeletal system is a made up of the muscular system and the skeletal system. The skeletal system provides the internal framework for the body, it protects the organs by enclosing it and anchors skeletal muscles so that the muscles can contract thus causing movement. The skeleton is divided into two divisions: the axial skeleton and the appendicular skeleton (Taylor & Cohen, 2013, p. 94). The Axial skeleton are the bones that have formed the longitudinal axis of the body which is made up of the skull, the vertebral column and the thoracic cage (Taylor & Cohen, 2013, p. 98). The Appendicular skeleton are the bones of limbs and griddles that are attached to the axial skeleton (Taylor & Cohen, 2013, p. 103).

Bone serves the organism at multiple levels: As a system, bones permit the organism to locomote effectively and to maintain posture by bearing loads without deformation, by providing rigid attachment sites for muscles and acting as a system of levers to amplify small movements. As an organ, bones protect the viscera and house the hemopoietic tissue (red marrow). As a tissue, bones serve as a reservoir of readily mobilizable calcium, an

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.
