The Human Skeletal Structure Of Ligaments

A. long bones are the thickest midway down the diaphysis, where the stresses are the greatest.

Compact bone forms the outer layer of the bone and spongy bone is surrounded by the compact bone. On close examination, the compact bone had thin lines of closely packed materials making it hard to compress, while the spongy bone appeared like a network and was soft to touch. This is because spongy bone are made up of thin cells (trabeculae) separated by spaces (lacunae). For color difference, compact bone is cream colored while spongy bone is reddish in color.

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

The epiphyses are the proximal and distal ends of a bone that consists mainly of spongy bone. (Tortora and Derrickson, 2011). Originally the epiphyses are separated from the diaphysis by a layer of cartilage that later fuses together through ossification. (CollinsDictionary [online], 2012).

know as physis, is the area of growing tissue near the end of the long bones in people.

Introduction. The skeletal system consists of the bones, along with the cartilage and fibrous connective tissue that make up the ligaments that connect bones to bone at joints.

Describe the microscopic features of osseous tissue that normally help long bones withstand lateral stress without breaking.

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.

The framework of the human body is the skeletal system. Skeletal system organs include the bones, joints, cartilages, ligaments, tendons and teeth. Bones offer support for the muscles, protect our vital organs, and allow us to eat food. Our joints allow our body to move, twist and bend. Cartilage, like our ears and nose, offer soft structures that are more malleable than bones. Two separate bones are connected by ligaments, and bones and muscles are connected by tendons. Our teeth allow us to bite and chew our food. Skeletal structure is similar among all people around the world, with the greatest diversity occurring between the sexes. We will explore each system in greater detail and provide

The three long bones are Femur, Tibia, and Fibula. The long bone elongated bone consisting of a body (diaphysis) and two terminal parts (epiphyses). The diaphysis is the long central shaft, it is made up a cortical bone it is also known as compact bone and normally contains a bone marrow and fat (adipose tissue). The shaft is composed of compact bone surrounding a central medullary cavity which contains a yellow marrow. The red marrow was based on blood whereas the yellow was based store fat. A fibrous connective tissue covers and protects the diaphysis. At the end of a long bone, there is epiphysis."Metaphysis is the wide portion of a long bone between the epiphyses and the narrow diaphysis". The epiphyses have around a swollen end of the

The structure in the middle was identified as an osteon with a Haversian canal in the middle of it. An osteon is a series of concentric layers of compact bone tissue, or lamellae, in the very center is the Haversian canal. The canal contains a sequence of tubes that let nerves and blood vessels travel through the bone.

The microscopical anatomy of compact bone are composed of osteon, canals/canaliculi, and interstitial and circumferential lamellae. The osteon is considered the structural unit of the bone, which is wrapped in bone matrix called lamellae. These cylinder-reminiscent structures act as pillar to bear weight. Canals perforate though the center of osteons and are filled with blood vessels and nerve fibers. Interstitial and circumferential lamellae help fill gaps between osteons and provide support to long bones against twisting. Spongy bone has no particular structure and is scattered. Its function is help cushion bones and stores bone between its trabeculae. These significant features help bone tissue thrive its role of assisting support, but factors like diet, age, and environment can cause the decay and brittleness of the bone which later leads to the condition of

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
