A radiograph reveals epiphyseal lines in the lengthy bones of a 12- year-old"s hand. Which of the following statements is correct?The epiphyseal plates have actually ossified and also even more expansion in size is not feasible. Administration of development hormone will stimulate even more bone expansion in length. Intramembranous ossification will certainly enable continued development in size. More growth will take place throughout the teenage years as sex hormones stimulate rebuilding of epiphyseal plates.
Appositional expansion produces:development in width. endochondral ossification. growth in size. Intramembranous ossification.
As a result of the boost of testosterone at puberty for males:appositional bone development increases. osteoblasts rise the price of bone resorption. epiphyseal plates widen rapidly. intramembranous ossification boosts.
Blood cells are made in the red bone marrowhead of bones, a process known as:bone resorption. ossification. hematopoiesis. osteoporosis.
Bone development and remodeling depends on enough intake of:sodium, calcium, and vitamin E. vitamin A, vitamin C, and also chlorine. calcium, vitamin C, and vitamin K. calcium, magnesium, and also vitamin B.
Bone development in size occurs at the epiphyseal plate in:flat bones. long bones. brief bones irconstant bones.
Bones are constantly undergoing resorption for assorted factors. Which of the adhering to cells accomplishes this process?osteogenic cell osteoblast osteoclast osteocyte
Bones with a diaphysis and epiphyses are classified as:short bones. flat bones. irregular bones. long bones.
Branching "ribs" of bone present in spongy bone are recognized as:canaliculi. trabeculae. lamellae. lacunae.
Charlie has a break in the shaft of his thigh bone. He damaged the:epiphysis. articular cartilage. diaphysis. epiphyseal plate.
Correctly order the adhering to vital measures in the procedure of endochondral ossification.
You are watching: Why are collagen fibers a critical component of bone?
1. Chondrocytes die.
2. Osteoblasts build the bone collar on the external surchallenge of the bone.
3. Perichondrium is got into by blood vessels.
4. In the major ossification facility, osteoblasts rearea calcified cartilage via early on spongy bone.

5. Perichondrial cells distinguish right into osteogenic cells then right into osteoblasts.3, 1, 4, 5, 2 3, 5, 2, 1, 4 3, 1, 2, 3, 5 4, 3, 2, 1, 5
For a perboy that starts running for exercise,bone deposition exceeds bone resorption. bone deposition is not related to bone resorption. bone deplace amounts to bone resorption. bone deposition is much less than bone resorption.
How would certainly the removal of hydroxyapatite crystals from bone matrix impact the physical properties of a bone?The bone would certainly be less versatile. The bone would certainly be more powerful. The bone would certainly be even more functional. The bone would be much less compressible.
In the epiphyseal plate, cartilage grows:in a circular fashion. from the edges inward. by pulling the diaphysis toward the epiphysis. by pushing the epiphysis ameans from the diaphysis.
Intramembranous ossification occurs in:secondary bone. arm and also leg bones. long bones. skull bones.
Osteoblasts are to bone deposition as:osteoclasts are to hematopoiesis. osteocytes are to fat storage. osteocytes are to bone development. osteoclasts are to bone resorption.
Key ossification centers construct in long bones in the:epiphyses. diaphysis. articular cartilage. periosteum.
Relatively inenergetic bone cells that assist to preserve the ECM are:osteogenic cells. osteoclasts. osteoblasts. osteocytes.
Secondary ossification centers are characteristic of:mesenchymal ossification. endochondral ossification. intramembranous ossification. appositional development.
The layers of bone tworry instantly deep to the periosteum are:circumferential lamellae. trabeculae. concentric lamellae. lacunae.
The patella is classified as a sesamoid bone considering that it:has actually an irconsistent form. has actually a diaphysis and also epiphyses. is situated within tendons. is longer than it is wide.
The periosteum is secured to underlying bone by collagen fibers called:canaliculi. trabeculae. Volkmann"s canals. perforating (Sharpey"s) fibers.
The little, fluid-filled cavity occupied by an osteocyte is dubbed a(n):osteon. lacuna. central canal. trabecula.
The term diploë refers to the:two kinds of marrow discovered within a lot of bones. reality that a lot of bones are developed of 2 forms of bone tproblem. interior layer of spongy bone in level bones. double-layered nature of the connective tworry covering the bone.
Thin, broad bones need to be classified as:brief bones. flat bones. irregular bones. long bones.
What accounts for the majority of bone (osseous) tworry matrix?bone marrow collagen fibers calcium salts osteoid
What canals affix lacunae together?main (Haversian) canals canaliculi perforating (Volkmann"s) canals main canals
What cells add to the process of calcification during intramembranous ossification?osteoclasts keratinocytes osteocytes osteoblasts
What hormone promotes a boost in the activity of osteoclasts?estrogen testosterone calcitonin parathyroid hormone (PTH)
What is the last process to occur in the epiphyseal plate?maturation proliferation calcification ossification
What prompts the closure of the epiphyseal plate approximately age 18- 21?chondrocytes actively divide chondrocytes boost in size and also mature mitosis in the zamong calcification ossification of the zone of proliferation
What framework allows the diaphysis of the bone to rise in length?lacunae epiphyseal plate osteon epiphyseal line
What tproblem serves as the design for bones created throughout endochondral ossification?spongy bone hyaline cartilage compact bone fibrocartilage
What kind of bone growth carry out you think a 40-year-old male experiences?lengthwise expansion endochondral ossification longitudinal development appositional development
What type of bone is adjusted to withstand stresses arriving from many kind of directions?spongy bone compact bone lamellar bone osteon bone

Which statement finest defines major bone?Primary bone is stronger than second bone since it consists of many lamellae. Key bone includes plentiful osteocytes and little inorganic matrix. Key bone has actually consistently arranged parallel bundles of collagen fibers for stamina. Key bone includes a greater percentage of inorganic matrix than additional bone.
