This figure illustrates bone growth in length at the Epiphyseal Plate. What is zone "C"? This figure illustrates bone growth in length at the Epiphyseal Plate.
Which of the labeled parts of the bone is composed primarily of compact bone Abcde?
Which of the labeled parts of the bone is composed primarily of compact bone? The shaft of an adult long bone is composed of compact bone.
What event at letter B leads to elongation of the bone formation of compact bone?
What event at letter B leads to elongation of the bone? Ossification of the epiphysis of a long bone. During bone growth, which significant event occurs at the surface indicated by the letter C?
Which bone forming process is shown in the figure?
A step in which bone-forming process is shown in the figure? endochondral ossification; the figure illustrates a step in the embryonic formation of a bone from a cartilage model.
Where is the spongy bone located?
Spongy bone is found mostly at the ends of bones and joints. About 20% of the bone in your body is spongy. Unlike compact bone that is mostly solid, spongy bone is full of open sections called pores.
What is compact bone and spongy bone?
Compact bone is dense and composed of osteons, while spongy bone is less dense and made up of trabeculae.
Which structure is only found in compact bone?
Compact bone consists of closely packed osteons or haversian systems. The osteon consists of a central canal called the osteonic (haversian) canal, which is surrounded by concentric rings (lamellae) of matrix. Between the rings of matrix, the bone cells (osteocytes) are located in spaces called lacunae.
Which structure is only found in spongy bone?
Spongy bone tissue does not contain osteons that constitute compact bone tissue. Instead, it consists of trabeculae, which are lamellae that are arranged as rods or plates. Red bone marrow is found between the trabuculae. Blood vessels within this tissue deliver nutrients to osteocytes and remove waste.
What bone associated structures in Panel C are indicated by the arrow periosteum epiphyseal plate Osteon trabeculae?
What bone-associated structures in panel C are indicated by the arrow? The honeycomb-like network of spongy bone is constructed of bony plates called trabeculae. Osteoblasts in the periosteal layer form compact bone characteristic of the exterior surface of a mature bone.
Which letter in the diagram indicates the tissue that contains many osteoblast and is responsible for bone growth and repair?
Which letter in the diagram indicates the tissue that contains many osteoblasts and is responsible for bone growth and repair? E. a bony process shaped like a pulley.
Which represents the correct sequence of development of bone cells?
Units 5-8
| Question | Answer |
|---|---|
| What structure in the diagram is the only place on a long bone NOT covered by the periosteum? | all of these |
| Which represents the correct sequence of development of bone cells? | osteogenic cells → osteoblasts → osteocytes |
Which of the following is the major component of the part of the bone labeled E?
Which of the following is the major component of the part of the bone labeled E? Yellow bone marrow within the medullary cavity is composed primarily of adipose tissue (fat).
What is associated with spongy bone?
Spongy (Cancellous) Bone Spongy bone consists of plates (trabeculae) and bars of bone adjacent to small, irregular cavities that contain red bone marrow. The canaliculi connect to the adjacent cavities, instead of a central haversian canal, to receive their blood supply.
Where is cancellous bone?
Cancellous bone is the meshwork of spongy tissue (trabeculae) of mature adult bone typically found at the core of vertebral bones in the spine and the ends of the long bones (such as the femur or thigh bone).
Where is spongy and compact bone located?
Compact bones are the present in the outer layer of long bones, while spongy bones are present in the middle of the long bones. The main difference between spongy and compact bones is their structure and function.
What is structure of compact and spongy bone?
Compact bone is dense and composed of osteons, while spongy bone is less dense and made up of trabeculae. Blood vessels and nerves enter the bone through the nutrient foramina to nourish and innervate bones.
What bones are compact bones?
Compact bone forms a shell around cancellous bone and is the primary component of the long bones of the arm and leg and other bones, where its greater strength and rigidity are needed.
What bone cells are found in compact bone?
Compact bone consists of closely packed osteons or haversian systems. The osteon consists of a central canal called the osteonic (haversian) canal, which is surrounded by concentric rings (lamellae) of matrix. Between the rings of matrix, the bone cells (osteocytes) are located in spaces called lacunae.
What are the bone structures?
Bones consist of different types of tissue, including compact bone, spongy bone, bone marrow, and periosteum. All of these tissue types are shown in Figure below. Compact bone makes up the dense outer layer of bone. Its functional unit is the osteon. Compact bone is very hard and strong.
What is epiphysis bone?
epiphysis, expanded end of the long bones in animals, which ossifies separately from the bone shaft but becomes fixed to the shaft when full growth is attained. The epiphysis is made of spongy cancellous bone covered by a thin layer of compact bone.
What type of cell is shown at a osteoblast?
Osteoblasts are cuboidal cells that are located along the bone surface comprising 4–6% of the total resident bone cells and are largely known for their bone forming function (22).
Which letter in the diagram indicates the diaphysis?
Which letter indicates the part of a long bone that in an adult is filled with yellow bone marrow? This part is also called the diaphysis. D.
Which of the following structures are associated with the osteon?
The osteon consists of a central canal called the osteonic (haversian) canal, which is surrounded by concentric rings (lamellae) of matrix.
Which of the following represents the correct sequence of zones in the epiphyseal plate?
The correct sequence is calcification, maturation, proliferation, reserved.
What is the structure of bones?
As shown in Figure below, the basic structure of bones is bone matrix, which makes up the underlying rigid framework of bones, composed of both compact bone and spongy bone. The bone matrix consists of tough protein fibers, mainly collagen, that become hard and rigid due to mineralization with calcium crystals.
Which of the following bones are part of the axial skeleton?
The five parts of your axial skeleton include the bones in your skull, ossicles (small bones) of your middle ear, hyoid bone of your neck, vertebra (bones of your spine) and thoracic cage (ribcage).
What structures make up spongy bone?
Spongy bone consists of plates (trabeculae) and bars of bone adjacent to small, irregular cavities that contain red bone marrow. The canaliculi connect to the adjacent cavities, instead of a central haversian canal, to receive their blood supply.
Where is cancellous bone located?
Cancellous bone is the meshwork of spongy tissue (trabeculae) of mature adult bone typically found at the core of vertebral bones in the spine and the ends of the long bones (such as the femur or thigh bone).
What is compact and cancellous bone?
The key difference between compact and cancellous bone is their structure. Compact bone is the harder outer shell of the bone while cancellous bone is the inner porous, less dense layers of the bone. Bones are important components in assisting movement and granting a shape to the body.
What is the difference between cortical and cancellous bone?
Cortical bone is a dense tissue that contains less than 10% soft tissue. Cancellous or spongy bone is made up of trabecules shaped as plates or rods interspersed between bone marrow that represents more than 75% of the cancellous bone volume.
