The formation of blood cells is called. hemopoiesis. What does our bone store? Where do our bones store fat? yellow marrow.

Transcription

1 What are the 5/6 functions of the skeletal system? support, protection, movement, blood cell formation, storage, homeostasis The formation of blood cells is called hemopoiesis What does our bone store? fate, inorganic salts (calcium phosphate, magnesium, sodium, potassium, carbonates) Where do our bones store fat? yellow marrow Where do our bones store calcium phosphate and other inorganic salts? bone tissue 1/15

2 How many bones are found in the typical human body? 206 The central part of the skeleton is the axial skeleton What is the part of the skeleton called that attaches to the central section? appendicular What three sections of the body make up the axial division of the skeleton? head, neck, trunk What is the name of the bone that is found in the upper neck and under the jaw? hyoid 2/15

3 What is a more common name for the vertebral column? spine/backbone The rib cage is also known as the thoracic cage What sections of the body make up the appendicular skeleton? limbs (arms/legs), hands and feet The outermost membrane surrounding the outside of a bone is the periosteum Where are blood cells made? bone marrow/epiphysis/spongy bone 3/15

4 The pectoral girdle is made of the scapula and clavicle The Pelvic girdle is made of the coxal/pelvic bone What are the 4 classifications of bones by shape? long, short, flat, irregular The shaft of a long bone is called the diaphysis The hyaline cartilage at the end of the long bone is called articular cartilage 4/15

5 The hollow chamber within the diaphysis is called the medullary cavity What type of marrow stores fat? yellow The lining of the medullary cavity endosteum What are the two types of bone tissue? compact and spongy Mature bone cells are called osteocytes 5/15

6 The Haversian canals contain blood vessels and nerve fibers The connect the Haversian canals Volkmann's canals Broad, flat bones formed from membrane like sheets of connective tissue intramembranous bones Bones that start as hyaline cartilage endochondral bones the process of hyaline cartilage turning into bone ossification 6/15

7 primary ossification center middle of the diaphysis Secondary ossification center center of epiphysis The band of cartilage between the diaphysis and the epiphysis epiphyseal disk (growth plate) What happens to the bone as the cartilage continues to reproduce and ossify? increases in length Cartilage cells form cells called osteoblasts 7/15

8 Cells that produce the bone matrix osteoblasts Mature bone osteocyte A bone increasing in thickness is due to the periosteum Cells that dissolve bone tissue with in the medullary cavity osteoclasts The process of dissolving bone tissues to release stored minerals resorption 8/15

9 Joints are also known as articulation Immovable joints synarthrotic Slightly moveable joints amphiarthrotic Moveable joints diarthrotic/synovial fluid in the moveable joints synovial fluid 9/15

10 junctions at the synarthrotic joints sutures joint found at your shoulder ball and socket joint found at your elbow hinge joint found between your carpals gliding joint found at your vertebrae pivot 10/15

11 soft spots on an infants skull fontanels large opening in the uderside of the skull where the spinal cord enters Foramen magnum attaches the ribs to the sternum costal cartilage True ribs attach directly to the sternum False ribs attach indirectly (costal cartilage attaches to each other then to sternum) 11/15

12 ribs that do not attach to the sternum floating The pectoral girdle is made of the clavicle and scapula the pelvic girdle is composed of your pelvic bone/coxal bones the humerus, radius, and ulna are found in the arm The femur, tibia, and fibula are found in the leg 12/15

13 carpels, metacarpals, and phalanges are found in the hand tarsals, metatarsals, and phalanges are found in the feet when a bone is broken into two pieces complete fracture When a bone cracks on one side and not all the way through greenstick fracture When the bone is broken into many pieces or crushed comminuted 13/15

14 when the bone breaks through the skin open fracture when the bone breaks at a right angle transverse fracture when the bone breaks at an angle other than a right one oblique fracture when the bone breaks due to twisting spiral during the first stage of healing a broken bone a forms hematoma 14/15

15 During the second stage of healing a broken bone a callus forms fibrocartilaginous (soft) During the third stage of repairing a broken bone a callus forms bony occurs during the fourth stage of a bone fracture healing remodeling 15/15
