Beatrice Mwachugu Skeletal system and joints
Types of Bone cells
Osteobalsts
Produce extracellular matrix
Osteocytes
Keep bone healthy
Osteogenic cells
Production of osteoblasts and stem cells
Found in endosteum and periosteum
Osteoclasts
Break down bone tissue
Acts as a phagocyte
Located in endosteum and periosteum
Long Bones
Diaphysis
Shaft of long bone
Epiphysis
Made of distal and proximal epiphysis which are the fur ends of the long bone
Epipyseal plate
hyaline cartilage for bone growth
Periosteum
Outer layer
protects
made of dense irregular connective tissue
Attatchemnt site for tendons and ligaments
Inner layer
an osteogenic tissue
Endosteum
located in the lining of trabeculae
Medullary cavity
located in the diaphysis
Has yellow and red bone marrow
Fibrous joints
Gomposis
They are immovable
Example, teeth and mandible which is connected with a periodontal ligament.
Syndesmosis
Bones connected with dense irregular connective tissue
Cause little to no movement
Examples of syndesmosis
Distal fibula joint
Suture
Short interconnecting fibers.
Immovable joints
eg suture of the skull
Cartilaginous joints
Symphysis
its a slightly movable bone
Made of hyaline and fibrocartilage
Examples
Pubic symphysis
moves in women to allow child birth
Intervertebral discs
Synchondrosis
Slightly movable and made of hyaline cartilage
Examples of synchondrosis
Epiphyseal plate
Responsible for bone growth
Sternocostal joints
Synovial joits
Meniscus
Fibrocartilaginous and cushions the bone
Bursa
sac filled with synovial fluid to prevent friction
Synovial fluid
slippery fluid that provides lubrication
Synovial membrane
Secretes synovial fluid
Tendon sheath
Wraps around tendons
Joint capsule
Inner membrane
Synovial membrane made of areola connective tissue
outer membrane
composed of periosteum which has dense irregular connective tissue
Types of synovial joints
plane joint
intercarpal joints
intertarsal joints
Hinge joint
Elbow joint
Interphalangeal joints
condylar joint
wrist joints
Metacarpophalangeal
Saddle joint
Carpometacarpal joints
Ball and socket
Shoulder joints
Hip joints
Pivot
Radioulnar joints
Atlantoaxial joints
