Anatomy Bone Test

Four Steps of Bone Repair, Subdivisions of Human Skeleton, 3 Bone Diseases, ect.

TermDefinition
Volkmann's Canal Small channels in the bone that transmit blood vessels from the peristeum into the bone that communicates with the Haversion Canal
Structure of a long bone that allows for large amounts of weight and stress ephiphyses strengthen bone ends (wider), diaphysis is thicker in the middle, and spongy bone surrounded by compact
Functions of Vertebral Column encloses/protects spinal cord, allows for movement, distributes weight to lower limbs, provides attachments for muscles
Function of Facial Bone forms framework of the face, contains cavities for special sense organs, provides openings for passage of air food and water, secures teeth, anchors facial muscle, most are flat bones other than the mandible, all bones are connected by sutures
Spongy Bone internal bone, very porous, AKA concellous bone, mostly at bone ends, houses the majority of red and yellow marrow, important for blood production
Haversion Canal central canal in the middle of compact bone
Red Marrow found in spongy bone cavities of both long and flat bones, blood forming tissues (hematopeitic), head of femur and humerous of adults have a great deal
Foramen opening though a bone
Sharpey's Fibers collagen fibers that connect/anchor the periosteum to compact bone
Endosteum delicate connective tissues that lines the inside of the medullary/marrow cavity
Compact Bone outside layer of dense bone, gives bone tensile strength and weight bearing
Yellow Marrow fat storage in medullary cavity, can revert to red marrow to reproduce blood if person becomes severely anemic to produce blood
Osteon basic unit of structure in compact bone, canal surrounded by lamellea
Periosteum membrane that covers the outer surface of bone
2 Subdivisions of the Human Skeleton axial and appendicular
Axial skull, rib cage, and spinal column
Appendicular limbs
Different Types of Bone long bone, flat bone, spongy bone and compact bone
4 Functions of the Human Skeleton support, protection, movement, blood cell formation, and mineral storage
Wolff's Law bone in a healthy human or animal will adapt to the loads under which it is placed
Functions of Thoratic Cage protects heart and lungs, supports upper limbs, attachment for respiration muscles
Spine thorn like projection
Suture union of 2 bones
Groove rut in a bone
Process a bone prominence
Four Steps of Bone Repair Step 1: Hematoma Formation Step 2: Fibrocartilage Callus Formation Step 3: Bony Callus Formation Step 4: Bone Remodeling
Step 1 : Hematoma Formation blood vessels in the broken bone tear and hemmorage forming clotted blood at the break site
Step 2: Fibrocartilage Callus Formation within days, cappilaries grow into the hematoma while phagocytic cells begin to clear away dead cells
Step 3: Bony Callus Formation cartilage callus converted to bony callus of spongy bone
Step 4: Bone Remodeling bony callus is remodeled by osteoclasts/blasts, with the excess material in the exterior of thr bone and within medullary cavity being removed
Paget's Disease of Bone: CAUSES commonly thought to be caused by a childhood virus called Paramyxovirus Nucleocapsid
Paget's Disease of Bone: SYMPTOMS pain in the back, hips and neck, abnormal walking, bone fracture, bow legs, headaches, bine stiffness, and the sensation of pins and needles
Paget's Disease of Bone: TREATMENT there is no cure but medications such as painkillers and dietary supplements can help to reduce the breakdown of bones
Pagets's Disease of Bone: CONNECTION TO HOMEOSTASIS caused by a virus that isn't found in a normal bone
Osteitis Fibrosa Cystica: CAUSES caused by hyperparathyroidism which is the overproduction of the pararthyroid hormone and is commonly caused by benign growths of the glands
Osteitis Fibrosa Cystica: SYMPTOMS bone pain/tenderness, fracture, deformations and can cause kidney stones, nausea, constipation, fatigue and weakness
Osteitis Fibrosa Cystica: TREATMENT vitamin D treatment, removal of the thyroid gland, or a bone transplant
Osteitis Fibrosa Cystica: CONNECTION TO HOMEOSTASIS the overabundance of PTH causes osteoclasts to degrade bine at a faster rate and deposit great amounts of Ca2+ into the blood. bones become weaker and Ca is higher
Osteoporosis: CAUSES imbalance between new bone formation and old bone resorption. bones become brittle, thin and porous and are easy to break
Osteoporosis: SYMPTOMS there are generally no symptoms but may expirence back pain, poor posture, and frequently occuring fractures
Osteoporosis: TREATMENT maintaining a well balanced diet, taking vitamin D and calcium, exercising, not smoking, limiting alcohol, and preventing falls
Osteoporosis: CONNECTION TO HOMEOSTASIS bone resorption outpaces bone deposit and bones become very fragile
