Question
Case Study B. Skeletal System-Look Out Below: A Case Study on Bone Tissue Structure a Mrs. Debbie Morgan is a 45-year-old female who works as a stocking clerk for a local home improvement store. While she was at work today a large box of metal rivets fell from a 20-ft -high overhead shelf, striking he outstretched arm and knocking her to the ground. The ambulance personnel reported that she had lost quite a b of blood at the accident scene and was "knocked out" when they arrived. To minimize further hemorthage, the paramedics applied a pressure bandage to her arm You meet the paramedics as they bring Mrs. Morgan into the emergency room and begin to assess her for injuries. She is awake and alert, but complaining of severe left arm and back pain, plus she has a "killer headache." To fully examine her injuries you remove four blood-soaked bandages from her arm. You notice large open wound on her arm with what appears to be bone tissue sticking out of the skin. She also has bruis covering her left shoulder, left wrist, and lower back. To determine the extent of her injuries Mrs. Morgan undergoes several x-rays, which reveal the following 1) fracture of the left humerus at the proximal diaphysis, 2) depressed fracture of the occipital bone, 3) fracture of the 3rd lumbar vertebral bodyExplanation / Answer
1.
Hemorrhage:
It's the medical term for bleeding. Hemorrhage is blood escaping from the circulartory system. It can be internal, external.
Fracture :
It's the medical term for broken bone. It's defined as the medical condition in which there is a damage to the continuity of the bone.
Proximal :
Anatomically proximal refers to the location that's nearer to the center of body or point of attachment.
Diaphysis:
It's the main or mid section of a long bone. It's the shift of long bone.
2.bones are classified according to the shape into 4 types namely, long bones, short bones, flat bones , irregular bones.
Humerus is long bone.
Occipital bone a part of skull bone is a flat bone.
3rd lumbar Vertebra is irregular bone.
3.
The body of vertebrae is composed of cancellous bony tissue.
Cancellous bony tissue is a mesh work of spongy tissue - trabaculae. It is porous type of tissue usually found at the ends of long bones, vertebrae body.it consists of osteocytes seated in small cavity called lacuna . these are housed in trabaculae matrix with bone marrow.
Functions include production of red blood cells-erythropoeisis from red bone marrow, reduces weight of the skeleton and provides strength and flexibility to the bones.
It's one among the 2 types of bony tissue,, the other being compact.
4.diaphysis of long bones are made of compact bones.
Diaper sis has a hollow cavity inside called the medullary cavity that has the yellow marrow. It's lined by endosteum. The outer surface of the diaphysis is covered by connective tissue called the periosteum.
