2. the portion of a long bone formed from a primary center of ossification. EPIPHYSIS- 1. The end of a long bone that is originally separated from the main bone by a layer of cartilage but that later becomes united to the main bone through ossification. HYALINE CARTILAGE- a type of connective tissue composed of specialized cells in a translucent, pearly blue matrix. Hyaline cartilage thinly covers the articulating ends of bones, connects the ribs to the sternum, and supports the nose, the trachea, and part of the larynx.
1- Which minerals are stored in bones? (five minimum) The minerals that are stored in your bones are calcium, phosphorus, potassium, iron, and zinc. 2- Which type of bone provides a large, flat surface area for muscle attachment? The type of bone that provides a large, flat surface area for muscle attachment in a flat bone. 3- Describe the [location, composition, and function] of the epiphyseal plate.
E) parallel. 59) The femur can withstand ________ times the body weight without breaking. 59) ______ A) 3 B) 8 C) 5 to 10 D) 20 E) 10 to 15 60) ________ marrow is found between the trabeculae of spongy bone. 60) ______ A) Bone B) Gray C) Yellow D) Red E) White 61) ________ bone reduces the weight of the skeleton and makes it easier for muscles to move the bones. 61) ______ A) Spongy B) Sesamoid C) Long D) Short E) Irregular 62) Intramembranous ossification begins with the ________ cells.
3. Describe the location, composition, and function of the epiphyseal plate. The epiphyseal plate is a layer of hyaline cartilage that allows the bone to grow in length. It is located in the Metaphysis of the growing bone. When the bone is finished growing, the hyaline cartilage is turned into osseous tissue.
Essay shows the importance of bones in human body and their main role, tasks they accomplish every day. Skeletal function Six functions of the skeleton: Support: Provides structural support for the entire body Protection: Surrounds soft tissue- ex. ribs and sternum protect the heart and lungs, - skull protects the brain Movement: Skeletal muscle is attached to bone so it pulls on the bone when it contracts Mineral homeostasis: Stores calcium and phosphorus--minerals are released into the blood when needed Blood cell production: Red bone marrow produces red blood cells, white blood cells and other blood elements. Storage: Storage of minerals and lipids (fats)-yellow marrow stores fat-(found in long bones) Bone. Definition: Bones are rigid organs that constitute part of the endoskeleton of vertebrates.

The human skeleton Is made up of 206 bones. The functions of the skeleton are to provide support, give our bodies shape, and provide protection to other systems and organs of the body, to provide attachments for muscles, to produce movement Joints A joint is the point where two or more bones meet. There are three main types of joints; Fibrous (immoveable), Cartilagenous (partially moveable) and the Synovial (freely moveable) joint. Fibrous joints Fibrous (synarthrodial): This type of joint is held together by only a ligament. Examples are where the teeth are held to their bony sockets and at both the radioulnar and tibiofibular joints.
174 – a) shaft of the bone, b) end of the bone, c) between the shaft and end of the bone 7. Describe the location, composition, and function of the epiphyseal plate, articular cartilage, and periosteum. Ans: pg. 174 – epiphyseal plate: located in the metaphysis, composed of hyaline cartilage, is the growth plate; articular cartilage: covers the part of the epiphysis where the bone forms an articulation with another bone, composed of hyaline cartilage, reduces fiction and absorbs shock at freely movable joints; periosteum: surrounds the bone surface wherever it is not covered by articular cartilage, is a sheath of dense irregular connective tissue containing osteoblasts, functions to protect the bone, assists in fracture repair, nourishes bone tissue, and serve as an attachment point for ligaments and tendons 8. Why is osseous tissue considered a connective tissue?
The joints give the body flexibility and allow movement to occur. Bones: An Overview * Identify the subdivisions of the skeleton as axial or appendicular. * Axial – bones that form the longitudinal axis of the body - skull, vertebral column, ribs, sternum * Appendicular – bones of the limbs and girdles – all others * List at least three functions of the skeletal system. * Support – framework that supports and anchors soft organs * Protection – protect soft organs * Movement – place for skeletal muscles to attach and use bones as levers to move the body * Storage – fat is stored in internal cavities, also stores minerals such as calcium and phosphorus * Blood cell formation – aka hematopoiesis – occurs within the marrow of certain bones * Name the four main kinds of bones. * Long bones – longer than wide with shaft and heads at both ends made mostly of compact bone (dense and looks smooth and homogeneous) – all bones of limbs except wrist and ankle bones * Short bones – cube-shaped and contain mostly spongy bone (small needlelike pieces of bone and lots of open space) – bones of the wrists and ankles, sesamoid bones (form within tendons), and patella
If you don’t take enough calcium trough food, you need Kirkland Signature Calcium. What is " Kirkland Signature Calcium. " (150 words) Calcium plays an important role in the human body. He is an enzyme activator, is responsible for the implementation of bioelectrical impulses, affects blood clotting, muscle spasms, as well as the production of hormones. It is a building block of bones and teeth, which transmits nerve
