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.
Why compact bone has canaliculi but spongy bone does not?
A compact bone has canaliculi but the spongy bone doesn't, because compact bone tissues form the outer layer of the bone while the cancellous bone tissues form the inner layer of the bone and it does not have osteons.
What are canaliculi and periosteum?
Canaliculi Small, hollow channels that link all of the osteocytes of the bone matrix together so nutrients and wastes can be transferred from one osteocyte to the next Osteoclasts Break down old bone when new bone laters form Periosteum Two-layers on the outside of bone
What are canaliculi and osteoclasts?
Canaliculi Small, hollow channels that link all of the osteocytes of the bone matrix together so nutrients and wastes can be transferred from one osteocyte to the next Osteoclasts Break down old bone when new bone laters form Periosteum Two-layers on the outside of bone First Layer; Tough, contains collagen and serves as a protective coating
What is the difference between compact bone and cancellous bone?
A compact bone has canaliculi but the spongy bone doesn't, because compact bone tissues form the outer layer of the bone while the cancellous bone tissues form the inner layer of the bone and it does not have osteons. Anosteon is a single central canal, with its contents, and the associated lamellae and osteocytes surrounding it.
Does spongy bone have lacunae?
Like compact bone, spongy bone, also known as cancellous bone, contains osteocytes housed in lacunae, but they are not arranged in concentric circles. Instead, the lacunae and osteocytes are found in a lattice-like network of matrix spikes called trabeculae (singular = trabecula) (Figure 7).
What is the major difference between compact and spongy bone?
Compact bones are the hard exterior, while spongy bones are the porous interior structures of bone tissue.
What is the canaliculi in bone?
Bone canaliculi are small canals running through the bone solid matrix, hosting osteocyte's dendrites, and saturated by an interstitial fluid rich in ions. Because of the small size of these canals (few hundred nanometers in diameter), fluid flow is coupled with electrochemical phenomena.
Where is the bone canaliculi?
Bone canaliculus. It is a small channel in ossified bone, particularly between the lacunae of ossified bone. It is where the filopodia of osteocytes project into. The osteocytes are able to distribute materials from adjacent blood vessels throughout the bone matrix via the bone canaliculi.
Why does compact bone have canaliculi but spongy bone does not?
Why does compact bone have canaliculi, but spongy bone does not? Nutrients and wastes cannot diffuse through compact bone.
What do both spongy and compact bone have in common?
Similarities Between Compact and Spongy Bone Both compact and spongy bones are made up of osseous tissue, which is a type of connective tissue that makes the bone. Both compact and spongy bones are involved in the movement of the body. Both compact bone and spongy bones contain calcium.
Is canaliculi found in compact bone?
Compact bone tissue consists of units called osteons or Haversian systems. Osteons are cylindrical structures that contain a mineral matrix and living osteocytes connected by canaliculi, which transport blood. They are aligned parallel to the long axis of the bone.
Which of the following is found in spongy bone but not compact bone?
trabecularThe trabecular is a structure that is characteristic of spongy bone (cancellous) tissue, but not of compact bone tissue.
What is the difference between compact bone and spongy bone quizlet?
Compact bone has more bone matrix and less space due to osteons. Spongy bones have less bone matrix and more space due to trabeculae.
Is canaliculi absent in cartilage?
Thus, Canaliculi can be seen in Bone. It is a tough, semitransparent, elastic and flexible tissue. The cartilage cells lie in groups of 2-3 in fluid-filled spaces called lacunae. Cartilage is present in the tip of nose, outer ear joint, between adjacent bones of the vertebral column, limbs and hands in adults.
What is spongy bone also called?
cancellous bone, also called trabecular bone or spongy bone, light, porous bone enclosing numerous large spaces that give a honeycombed or spongy appearance. The bone matrix, or framework, is organized into a three-dimensional latticework of bony processes, called trabeculae, arranged along lines of stress.
Does spongy bone have lamellae?
Spongy bone tissue does not contain osteons. Instead, it consists of trabeculae, which are lamellae that are arranged as rods or plates.
What is the major difference between compact and spongy bone quizlet?
Compact bone has more bone matrix and less space due to osteons. Spongy bones have less bone matrix and more space due to trabeculae.
How will you differentiate compact and spongy bones in terms of their cell arrangement?
Compact bone tissue is made of cylindrical osteons that are aligned such that they travel the length of the bone. Haversian canals contain blood vessels only. Haversian canals contain blood vessels and nerve fibers. Spongy tissue is found on the interior of the bone, and compact bone tissue is found on the exterior.
What is found in compact bone but not spongy?
Whereas compact bone tissue forms the outer layer of all bones, spongy bone or cancellous bone forms the inner layer of all bones. 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.
What is the difference between compact bone 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 not 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.
Where is canaliculi located?
Bone canaliculus. It is a small channel in ossified bone, particularly between the lacunae of ossified bone. It is where the filopodia of osteocytes project into. The osteocytes are able to distribute materials from adjacent blood vessels throughout the bone matrix via the bone canaliculi.
What is spongy bone filled with?
Spongy Bone (Cancellous Bone) Spongy bone is supplied by fewer and larger vessels than compact bone. These vessels perforate the outer compact layer and are distributed into the spongy portion of bone, which is filled with marrow. Bone marrow is tissue found in long bones, like the femur, that contains stem cells.
What is the role of canaliculi in compact bone?
Each lacunae is connected to the others through a fine network of canals, called canaliculi. The canaliculi supply nutrients to the osteocytes, remove cellular wastes, and enable communication between cells. Finally, compact bone is covered by a double-layered membrane called a periosteum.
Answer

What is the function of a gland?from quizlet.com
A gland is an organ that synthesizes and releases a substance. There are two major types of glands: endocrine and exocrine. In some cases, the substance released by a gland lubricates tissues of the body that are commonly abraded. For example, mucus glands secrete mucus to help lubricate the passage of food through the digestive tract. Given this information, which type of tissue will likely contain mucus glands?

Using pig organs could reduce the shortage of human organs. The axial skeleton includes the. vertebra, skull, and ribs. Osteoarthritis is a disease that results in a thinned or absent layer of cartilage surrounding bones, causing bones to rub against one another. This causes both pain and loss of motion.
What causes heat to flow away from the core?from quizlet.com
2) Blood vessels near the skin dilate allowing more blood to flow, which draws heat away from the core.
Why is the blood-brain barrier important?from quizlet.com
The blood-brain barrier occurs when the physical structures of the brain prevent blood from intermingling with the extracellular fluid of brain cells. This separation makes it difficult and dangerous to deliver drugs to specific regions of the brain. Therefore, further research on how the blood-brain barrier works is needed to allow more effective delivery of drugs. What potential ethical issues may inhibit such research?
