to tell you how old the frog is
The connective tissue you are referring to is bone tissue. It has a solid matrix composed of minerals, primarily calcium phosphate, which gives it its hardness. The lamellae (concentric rings) surrounding central canals are characteristic of compact bone, which is the more dense and strong type of bone tissue.
An osteon is composed of concentric rings of bone matrix called lamellae surrounding a central canal called the Haversian canal. Within the Haversian canal run blood vessels and nerves that supply nutrients to bone cells. Osteocytes, the bone cells, are located in spaces called lacunae between the lamellae.
Rings of calcified matrix that make up the Haversian system are called lamellae. These concentric layers surround the central Haversian canal, which contains blood vessels and nerves. The arrangement of lamellae provides strength and structural support to bone tissue. Together, they facilitate the organized distribution of nutrients and waste removal within the bone.
Frogs typically have around 26 chromosomes in their cells, although the number can vary between different species of frogs.
Because frogs has life
Legs
yes
Frogs have a skeleton made mostly of bone with some piecesmade ofcartilage.
Yes, frogs have shoulders and shoulder blades. Frogs, like people, also have one 'upper arm' bone called the humerus.
the function of a frog is to help it jump around
The eyes of the owl are fixed by sclerotic rings ( Sclerotic rings are rings of bone ) which stops the owls eyes from moving.
Bone
amphibians have a backbone a frog has a back bone and there cold blooded
Though the frog is an amphibian, it is also a vertebrate as it has a spine (back-bone).
The tissue that has cells arranged in concentric rings is bone tissue, specifically compact bone. This arrangement helps bone tissue withstand mechanical stress and provides strength and support to the body.
The concentric rings of compact bone, known as lamellae, are layers of bone tissue organized around a central canal, which contains blood vessels and nerves. These rings form cylindrical structures called osteons or Haversian systems, providing strength and structural support. The arrangement of lamellae allows for efficient nutrient delivery and waste removal, essential for bone health and maintenance. This intricate structure contributes to the overall durability and resilience of compact bone.
The matrix rings are called lamellae and they concentrically surround the central canal (Haversian canal) of each osteon. They form a series of concentric circles, providing structural support and strength to the bone tissue.
