Medullary cavity

spleen gradually decreases granulocytic production & involves itself solely in lymphopoiesis. Detectable levels of hemoglobin may be shown. Medullary Phase . Myeloid Phase • It begins in the 5th month of fetal development. Hematopoiesis begins in the developing bone marrow cavity • Medullary hematopoiesis occurs. It occurs in the medulla or inner part of the bone marrow • Mesenchymal cells (embryonic tissue) migrate into the core of the

Calcium is a vital nutrient in living complex organisms, humans and animals alike. It is utilized for stabilizing blood pressure, and is a major mineral in the bone. It is also critical for blood clotting and nerve and muscle functions. Without it, weakened bones and muscle dysfunction follow in effect. This deficiency is not uncommon, and is easily obtained with unbalanced diets especially in captive exotic animals. Metabolic Bone Disease is a syndrome that many animals accrue when they are not

Complete the following statements. The kidney is referred to as an excretory organ because it excretes 1 wastes. It is also a major homeostatic organ because it maintains the electrolyte, 2 , and 3 balance of the blood. Urine is continuously formed by

Osteomyelitis is an inflammation of the bone and bone marrow that can occur in any bone in the body, however, is more commonly seen in the long bones, the spine, and the foot bones of a diabetic. Osteomyelitis typically begins as an infection of the medullary cavity, quickly extends to the periosteum, and settles in the calcified portion of the bone. Even with the significant advances in diagnosing and treating these types of infections, long bone osteomyelitis still presents a variety of challenges and

Lateral and Middle --- to the left E. None 63. Which sentence related to the medullary substance of the kidneys is wrong A. Is situated at the outer part of the kidney B. Contains the “corpuscular renis” C. Is made up of renal pyramids D. Is a part of each renal lobe E. Is situated at the inner part of the kidney 2 The posterior layer

Haller (1763) injected a clear fluid into the periosteum showing that “the origin of bone is the artery carrying the blood and in it the mineral elements” putting forward the idea that the cardiovascular system was responsible for bone formation. This was supported by the previous work of Hunter (1754) Pritchard (1946) studied what triggers osteogenesis: the same stimulus causing inflammation or mechanical stress. How was the study conducted? Pritchard (1946) suggested osteogenesis is a result of

responsible for the acquired immune response against antigens, are scattered throughout the body and filter out microbes. The spleen also plays a significant role in mounting immune responses to antigens in the blood stream. It is located in the abdominal cavity and acts as a filter for peripheral blood. The spleen consists of two basic tissues which are red pulp and white pulp. MALT produce the immune responses against pathogens that invade the mucosa which line the tracts such as respiratory or alimentary

The control of respiration is a non-conscious act that is maintained in the brain through neuronal control. Overall, what initiates and controls respiration and ventilation resides in the respiratory control centers of the brain: the medullary respiratory center, pons respiratory center, and pre-Botzinger complex. The pre-Botzinger complex is an area in the upper end of the medulla that is responsible for the baseline rhythmic activity in respiration (Ramirez). During quiet breathing, the dorsal

Cryptococcosis is a chronic mycotic infection caused by Cryptococcus neoformans variation neoformans and Cryptococcus neoformans var. gattii, both considered opportunistic. Though the organism is usually harmless to humans, the yeast type fungus can severely affect those with severe immunosuppression, such as HIV and AIDS patients.      In 1894 Greifswal Medical Society was presented with a paper by a pathologist named Busse, stating that he managed to isolate yeast from

Diaphysis- shaft Epiphysis- ends of bone; contain red marrow Medullary cavity- contains yellow marrow Epiphysis plate- found between diaphysis and epiphysis; long bone growth 15. Differentiate between osteocytes, osteoclasts and osteoblasts. Osteoclast- cells which dissolve bone Osteoblast- cells which build bone
