Exam 2 study guide Below is the list of topicsstructures that Will be included in the lecture Exam 2 a What are bones a Bone are made up of many different kinds of tissue and they are part of the structure of our body We have bones for these reasons i Support ii Movement iii Protection iv Mineral storage V Blood cell formation and energy storage vi Energy metabolism b Are bones considered organs Why a Yes bones are considered organs because they contain several different types of tissues including i Bone tissue Which predominates ii Nervous tissue in nerves iii Blood tissue in blood vessels iv Cartilage in articular cartilages v Epithelial tissue lining blood vessels c What are sutural and sesamoid Bones a Sutural bones are extra bones inside of one s skull These are markers for disease down syndrome b Sesamoid bones are bones that develop from the tendons patella d What makes up the skeletal system a Bones cartilage ligaments and other connective tissue e What is the function of the skeletal system a Support protection body movement homopoiesis and mineral storage f What are the types of cartilage tissue Where are they found a Hyaline cartilage is found in places like articular cartilage of a joint or the coastal cartilage the cartilage in intervertebral discs and the larynx trachea and lung b Elastic cartilage is found in places like the ear and nose c Fibrocartilage is found in places like the meniscus articular cartilage of a joint and the pubic symphysis g What is the difference between ligaments and tendons Which one prevents and Which one promotes movement a Ligaments attach bone to bone and prevent movement b Tendons attach bone to muscle and promotes movement h What are osteoblasts osteoclasts and osteocytes a Osteoblasts are what secrete collagen and matrix and also hormones that regulate sugar metabolism b Osteoclasts are monofied monocytes that are large multinuclear bone resorbing cells They secrete acid to disolve mineral part of bone c Osteocytes are mature cells formed when matrix surrounds osteoblasts i What are long short at and irregular bones What are their functions Where are they found a Long bones are more

red bone marrow is found in at bones Yellow bone marrow make red blood cells in emergency cases m What are compact and spongy bones What are their functions Where are they located a To the human eye compact bone looks solid but it is riddled with passage ways for blood vessels and nerves Compact bone is in places like the shaft of a long bone b Spongy bone looks like a sponge This type of bone distributes stress and reduces weight It is located in the epiphyseal plate on long bones 11 What is ossification a Ossification is bone remodeling o What is endochondral and intramembranous
