Cartilage and Bone connective tissue
Terms in this set (44)
A connective tissue that is more flexible and resilient than bone and that protects the ends of bones and keeps them from rubbing together.
Cells that produce the matrix of cartilage
is a former chondroblast that has become enclosed in a lacuna in the cartilage matrix; maintain the matrix and ensure that it remains healthy and viable
Small cavities in the bone or cartilage that hold individual bones or cartilage cells.
Mature cartilage is avascular (not penetrated by blood vessels)
Functions of Cartilage
supports soft tissues, lines articular surface of bone, template for bone formation
Types of Cartilage
Hyaline, Elastic, Fibrocartilage
1. Is the most abundant cartilage in the body. 2. Affords flexibility and support. 3. Is found at joints; reduces friction between bones. 4. Is the weakest of the three types of cartilage
A weight-bearing cartilage that withstands compression; forms the intervertebral discs, the pubic symphysis & cartilage pads of the knee joints (menisci)
Cartilage with abundant elastic fibers; more flexible than hyaline cartilage. found in auricle of ear, external auditory canal and the epiglottis
Dense irregular connective tissue membrane covering Hyaline and Elastic cartilage
Bone Connective tissue
aka osseous connective tissue; Primary component of Bone;
The hardest and most dense connective tissue type
Also called mineralization: the process of deposition of mineral salts such as calcium and magnesium phosphates into a tissue
Function of Bones
support, protection, movement, mineral storage (calcium and phosphate), blood cell formation
Blood cell formation
Red bone marrow
Hemopoietic tissue that manufactures red blood cells, hemoglobin, white blood cells, and thrombocytes. Located within the spongy bone.
In adults located in the proximal epiphyses of the femur and humerus, the vertebrae, the ribs, the sternum, and the hip bones
essential mineral for body functions such as muscle contraction, blood clotting, and nerve impulse transmission.
mineral needed for ATP utilization
4 classes of bones
long, short, flat and irregular
Most common bone shape; A type of bone that is longer than it is wide. Examples include the femur, humerus, and phalanges.
Elongated shaft of a long bone.
Ends of long bone
Equal in length and width and contain a thick interior of spongey bone covered by a thin veneer of compact bone; carpals and tarsals, sesamoid bones
Are thin and flattened bones. They possess a broad flat surface for muscle attachment or protection of underlying organs. These include the sternum, ribs, scapula and certain skull bones.
Shaped like a sesame seed; A special type of short bone that form in a tendon; ex:patella
Complicated shapes, vertebrae, coxal bone
Contains the growth portion of the bone and are located where the diaphysis and epiphysis converge. Depending on the bone's age it can contain the Epiphyseal plate (child) or epiphyseal line (adult).
A dense fibrous membrane covering the surface of bones (except at their extremities) and serving as an attachment for tendons and muscles.Protects the bone from surrounding structures and anchors the blood vessels and nerves to the surface of the bones
Covers the ends of bone, protection during movement and cushions reduces friction and absorbs shock to the joint
yellow bone marrow
Functions as a fat storage area. Composed chiefly of fat cells and is located in the medullary cavity of long bones.gradullay replaces red bone marrow in adults
4 types of cells are found in bone connective tissue
osteoprogenitor, osteocytes, osteoblasts, and osteoclasts
differentiate from mesenchyme and are found in numerous locations including the innermost layer of the periosteum and in the endosteum lining of the medullary cavities; have the ability to differentiate into osteoblasts
Bone-forming cells found in the periosteum. Immature cells that secrete organic form of bone matrix called Osteoid; they differentiate into osteocytes
- the organic matrix of bone; young bone that has not undergone calcification
Mature bone cells; reside in within the lacunae in the bone matrix; maintain the bone matrix and detect mechanical stress on a bone
large, multinuclear phagocytic cells; involved in bone resorption
osteoclasts break down bone by secreting HCl which dissolves the minearal parts of the bone matrix and releases the minerals (calcium and phoshate), resulting in a transfer of calcium and phosphate from bone fluid to the blood
Process of dissolving bone matrix and releasing stored minerals
2 types of bone connective tissue present in most bones
Compact bone and Spongy bone
The unit of combact bone, also called a Haversian system. Osteons are essentially long cylinders of bone; the hollow center is called the central canal, and is where blood vessels, nervs, and lymphatic vessels are found. Compact bone is laid down around the central canal in rings (lamellae).
Layer of bone tissue having many small spaces and found just inside the layer of compact bone.
Hard, dense bone tissue that is beneath the outer membrane of a bone`
Vitamin A- activated osteoblasts
Vitamin D- Promotes absorption of calcium and phosphate into blood and helps with calcification of bone
A process through which new bone tissue is formed at the growth plates of long bones
