What is the white substance found at the end of bones?

Spongy bone is found mostly at the ends of bones and contains red marrow. Bone marrow is found in the center of most bones and has many blood vessels. There are two types of bone marrow: red and yellow. Red marrow contains blood stem cells that can become red blood cells, white blood cells, or platelets.

What are the ends of the bone called?

The end of the long bone is the epiphysis and the shaft is the diaphysis. When a human finishes growing these parts fuse together. The outside of the flat bone consists of a layer of connective tissue called the periosteum.

Which of the following is not a function of bone?

Option D:production of body heat: The skeleton serves six major functions: support, movement, protection, production of blood cells, storage of minerals and endocrine regulations. Hence, production of body heat is not a function of the skeletal system.

What is the white tissue that covers the surfaces of bones where they form a joint?

In a joint, hyaline cartilage is referred to as articular cartilage. This is because the cartilage covers bones' surfaces where they articulate, or meet to form the joint. For example, at the knee joint, the top of the tibia, the bottom of the femur, and the back of the kneecap are covered with articular cartilage.

What is the material in the center of most of your bones?

The soft bone marrow, which is found inside many bones, makes most of the body's red blood cells, white blood cells, and platelets.

Do ligaments reduce friction?

Tendons are similar to ligaments and fasciae as they are all made of collagen, but a ligament joins one bone to another and fasciae connect muscles to other muscles. ... This helps to reduce friction between the bones and allows for free movement.

What helps reduce friction at joints?

Cartilage helps reduce the friction of movement within a joint. Synovial membrane. A tissue called the synovial membrane lines the joint and seals it into a joint capsule. The synovial membrane secretes a clear, sticky fluid (synovial fluid) around the joint to lubricate it.

What are the major types of bone markings?

There are three general classes of bone markings: (1) articulations, (2) projections, and (3) holes. As the name implies, an articulation is where two bone surfaces come together (articulus = “joint”).

What is cartilage?

Cartilage is the main type of connective tissue seen throughout the body. It serves a variety of structural and functional purposes and exists in different types throughout our joints, bones, spine, lungs, ears and nose.

Which of the following is the function of the bones?

Bones have many functions. They support the body structurally, protect our vital organs, and allow us to move. Also, they provide an environment for bone marrow, where the blood cells are created, and they act as a storage area for minerals, particularly calcium.

What do osteoblasts do quizlet?

Osteoblasts are bone forming cells, they are matrix synthesizing cells responsible for bone growth.

Is contraction a function of bones?

Bones also play an important role in the movement of your body, transmitting the force of muscle contractions. Your muscles attach to your bones via tendons. When your muscles contract, your bones act as a lever while your joints form a pivot point.

What is hyaline cartilage?

Hyaline cartilage is the glass-like (hyaline) but translucent cartilage found on many joint surfaces. It is also most commonly found in the ribs, nose, larynx, and trachea. Hyaline cartilage is pearl-grey in color, with a firm consistency and has a considerable amount of collagen.

Where is hyaline cartilage function?

Function of Hyaline Cartilage

When hyaline cartilage is on the articular surfaces of bones (the surfaces at joints), it is called articular cartilage. Articular cartilage functions as a shock absorber and also reduces friction between bones where they meet at joints.

Where are the osteocytes?

Between the rings of matrix, the bone cells (osteocytes) are located in spaces called lacunae. Small channels (canaliculi) radiate from the lacunae to the osteonic (haversian) canal to provide passageways through the hard matrix.
