Difference between Bone and Cartilage

Main Difference

A bone has the definition of hard pieces of the body that have whitish tissue that completes the skeleton in humans and other vertebrates. Cartilage has the definition of a stiff, flexible and connected tissue and mostly have their location on the larynx and ear. Initially, they exist in large amounts in the body but when a person grows up, gets replaced by bone.

Basis of Distinction Bone Cartilage
Definition The hard pieces of the body that have whitish tissue that completes the skeleton in humans and other vertebrates. A stiff, flexible and connected tissue and mostly have their location on the larynx and ear.
Occurrence Initially, they exist in small amounts but gradually take over the body. Initially, they exist in large amounts in the body but when a person grows up, gets replaced by bone.
Types Compact bones and cancellous bones. Hyaline, fibro and elastic types.
Nature They have a hard texture, less flexible, also lack any flexibility but have toughness. It has a flexible nature with elasticity as a feature and flexibility existing.
Blood Supply They have an abundant supply of blood and therefore have more delicate features and strength. They do not have a supply of fresh blood except for the perichondrium.

Bone

A bone has the definition of hard pieces of the body that have whitish tissue that completes the skeleton in humans and other vertebrates. All through life, bone is continually restored through a two-section handle called rebuilding. This procedure comprises of resorption and development. Amid resorption, abnormal cells called osteoclasts separate and expel old bone tissue. Amid bone arrangement, new bone tissue is set down to supplant the old. A few hormones including calcitonin, parathyroid hormone, vitamin D, estrogen in ladies, and testosterone in men, among others, control osteoclast and osteoblast work. Bone tissue is a hard tissue, a sort of thick connective tissue. It has a honeycomb-like grid inside, which gives the bone unbending nature. Bone tissue comprises of various types of bone cells. Osteoblasts and osteocytes included in the development and mineralization of bone; osteoclasts are involved in the resorption of bone tissue. Changed osteoblasts turn into the coating cells that frame a protective layer on the bone surface. The mineralized grid of bone tissue has a natural part of fundamental collagen called Ossetia and an inorganic segment of bone mineral comprised of different salts. Bone mass is a mineralized tissue of two sorts, cortical and cancellous bone. Various kinds of tissue found in bones incorporate bone marrow, endosteum, periosteum, nerves, veins, and ligament.

Cartilage

Cartilage has the definition of a stiff, flexible and connected tissue and mostly have their location on the larynx and ear. Initially, they exist in large amounts in the body but when a person grows up, gets replaced by bone. The ligament is a versatile and smooth flexible fabric, elastic like cushioning that spreads and secures the finishes of long bones at the joints, and is an auxiliary segment of the rib confine, the ear, the nose, the bronchial tubes, the intervertebral plates, and numerous other body parts. It is not as hard and inflexible as bone, but rather it is considerably stiffer and a great deal less adaptable than muscle. Fibrocartilage is the ligament with the least number of chondrocytes, which implies it twists the slightest. It is the kind of ligament found in your knee, and in the middle of the vertebrae in your spine. Take note of what number of chondrocytes are on the slide underneath – just three! It bodes well, correct? You need something like your nose or ear that can be harmed effortlessly to be “bendy,” so they don’t break. Be that as it may, you don’t need your knees or spine to be shaky, so a more inflexible ligament is the approach. The ligament is comprised of specific cells called chondrocytes. These chondrocytes deliver a lot of extracellular lattices made from collagen strands, proteoglycan, and elastin filaments. There are no veins in ligament to supply the chondrocytes with supplements. The versatile ligament is the most adaptable, which implies it contains the most chondrocytes. It is the kind of ligament found in your ear.

Key Differences

  • A bone has the definition of hard pieces of the body that have whitish tissue that completes the skeleton in humans and other vertebrates. On the other hand, Cartilage has the definition of a stiff, flexible and connected tissue and mostly have their location on the larynx and ear. Initially, they exist in large amounts in the body but when a person grows up, gets replaced by bone.
  • Some of the main types of cartilage include the hyaline, fibro and elastic types. On the other hand, some of the primary types of bones include compact bones and cancellous bones.
  • The location of bones exists throughout the body from our skull, ribs, legs, arms, back and even thighs. On the other hand, the area of cartilage in our body ranges from ears. Nose, larynx, trachea, joints, discs, and epiglottis.
  • Cartilage has a flexible nature with elasticity as a feature and flexibility existing. On the other hand, bones have a hard texture, less flexible, also lack any flexibility but have toughness.
  • Bones always have an abundant supply of blood and therefore have more delicate features and strength, on the other hand, cartilage does not have a supply of fresh blood except for the perichondrium.
  • The matrix of cartilage may have calcium salts, but for most cases, it does not exist. Although, calcium salts lives in the bones.
