Bone Flashcards
A connective tissue with cells and fibers embedded on a gel- like ground substance.
Cartilage
Tightly packed collagenous fibers.
Dense connective tissue
Connective tissue with cells and fibers embedded in a calcified ground substance.
Bone
Is connective tissue in which the intercellular substance is rendered hard by being impregnated with mineral salts chiefly calcium.
There are 4 types bone cells
Bone or osseous tissue
These are osteoblasts that mature and migrate into the bone.
Osteocytes
Large cells found on bone surfaces responsible for resumption of bone matrix during growth and repair
Osteoclasts
Immature bone cells found in the periosteum and endosteum
Osteoblasts
Unspecialized cells which have the ability to differentiate into osteoblasts.
Osteogenic
A layer of osteogenic cells and osteoclasts that lines the medullary cavity.
Endosteum
A dense irregular fibrous connective tissue that covers the surface of the bone not covered by the articular cartilage.
Periosteum
Also known as cortical bone, very dense tissue organized in haversian systems.
Compact bone
The marrow cavity in the center of the bone site of blood cell production or fat storage.
Medullary cavity
Also known as cancellous bone. Forms a lattice-like structure of spiked bone called trabeculae.
Spongy bone
What are two types of bone marrow?
Red= blood cell plates and most white blood cells . Yellow= mostly fat - used as energy.
Compact bone of closely packed osteons.
Haversian system
A three dimensional sheet of connective tissue that permeates the body.
Fascia
Envelopes and holds the organs within their cavities.
Visceral fascia
Is composed mainly of areolar and adipose tissue.
It blends with dermis and fills unoccupied spaces.
Superficial fascia.
Covers and penetrates the muscle bones, nerves and blood vessels of the body. It forms ligaments tendons and joint capsules.
Deep fascia
Also known as sinews
Are tough bands of fibrous connective tissue.
Tendons
A short band of tough fibrous connective tissue composed mainly of long stringy collagen fibers.
Ligaments
Found where strong support and minimum movement are required comprises the intervertebral disks and the pubic symphysis .
Fibrocartilage
The most resilient cartilage
It provides strength
Found in the external ears and the epiglottis
Elastic cartilage
A dense type of connective tissue composed of collagen and elastic fibers embedded in a gel like ground substance.
Cartilage
A type of cartilage found at joints over the ends of the bones.
Where it is commonly referred to as gristle.
Most abundant cartilage in the human body.
Ex. Costal area
Hyaline cartilage
