Skeletal Tissue
What is cartilage made up of?
Chondrocytes
Dense outer layer on every bone that appears smooth & solid.
Compact Bone
What are the cavities that encase the eyes & lacrimal gland?
Orbits
Cushion-like pads between vertebrae acting as shock absorbers.
Intervertebral Discs
Peg-in-socket joints, only examples are the teeth in alveolar sockets.
Gomphoses
Made of highly resilient cartilage tissue, consists primarily of water. Contains no blood vessels or nerves.
Skeletal Cartilage
Made up of a honeycomb of small flat pieces of bone called trabeculae.
Spongy Bone
What is the largest & longest bone of the upper limb?
Humerus
How many true ribs do you have?
7
Joints that are immovable.
Synarthrose
Layer of dense connective tissue surrounding cartilage, helps resist outward expansion, contains blood vessels.
Perichondrium
What is the process of bone tissue formation?
Ossification (Osteogenesis)
80 bones in 3 regions; Skull, vertebral column, & thoracic cage. Support the head, neck, trunk, & protect the brain, spinal cord, & thoracic organs.
Axial Skeleton
What is the number of vertebrae within each region the cervical, thoracic, and lumbar
7 Cervical, 12 Thoracic, & 5 Lumbar
Bones separated by a fluid-filled cavity. Freely moveable, include almost all limb joints.
Synovial Joints
Cartilage-forming cells in perichondrium secrete matrix against external face of existing cartilage & new matrix lays on surface of cartilage.
Appositional Growth
Which cell of bone tissue breakdown bone?
Osteoclasts
Formed by hip bones, sacrum, & coccyx.
Pelvis
AKA the breastbrone, consists of manubrium, body, & xiphoid process.
Sternum
Where is your suture joint found?
The Skull
Chondrocytes within lacunae divide & secrete new matrix expanding the cartilage within. New matrix made within cartilage.
Interstitial Growth
What is the 1st step in bone repair?
Hematoma Formation
Not part of the skull or any other bone, acts as movable base for tongue & attaches muscles for swallowing & speech.
Hyoid Bone
Your floating ribs are attached to your sternum; True or False.
False; Floating ribs (11-12) have no attachment to the sternum.
Reduce friction where ligaments, muscles, skin, tendons or bones rub together.
Bursae
