both ______ and __________ bone have concentric lamallae. the difference is in how the lamallae are structured.
compact; spongy
central (haversian) canals are found only in:
compact bone
the structure is composed of dense regular connective tissue
ligament
This type of cartilage is found in the intervertebral discs;in the pubic symphysis; and as the meniscus of joints
fibrocartilage
this cartilage has a high content of the protein elastin. It is an unusual form of cartilage found in the ear and in the epiglottiselastic cartilagethis type of bone formation would best be observed in which of the following bones?humerusthis image shows a partially cross sectioned adult femur. the region shown at "3" is the:diaphysiswhich one of the following bones would show an epiphyseal plate in a 9 year old child?humerusnormal blood calcium is between 8.5 and 10.2 mg/dl. a blood calcium of 7.0 mg/dl would be expected to have what affect on calcitonin?decrease calcitonin levelsincreases in parathyroid hormone levels in the blood would be expected to have what effect on osteoclasts?stimulates osteoclastsweight-bearing exercise (moderate stress) works through the periosteum to stimulate ____________ activityOsteoblasticnormal blood calcium is between 8.5 and 10.2 mg/dl. a blood calcium of 7.0 mg/dl would be expected to have what effect on parathyroid hormone?increase parathyroid hormone levelsThe ischial_______________ of the pelvis are also called the "sit bones" because they are the structures you would feel if you fell on your buttocks from a great height.
