Study Notes
Fibrous Joints
- Fibrous joints connect bones with fibrous tissue
- They lack a joint cavity
- These joints are generally immobile or have limited movement
- Three main types: sutures, syndesmoses, and gomphoses
Sutures
- Location: Skull bones
- Characteristics: Continuous fibrous tissue that fuses with age
- Examples: Coronal suture
Syndesmoses
- Location: Between long bones (e.g., tibia-fibula)
- Characteristics: Movement depends on fibre length; connected by ligaments, can ossify and fuse with age, example interosseus membrane (radius-ulna)
- Examples: Interosseous membrane (radius-ulna)
Gomphoses
- Location: Tooth socket
- Characteristics: Peg-in-socket structure; periodontal ligament
- Examples: Teeth in alveolar sockets
Cartilaginous Joints
- Cartilaginous joints connect bones with cartilage
- They lack a joint cavity, and the movements are limited or slight
- Two main types: primary and secondary cartilaginous joints
Primary Cartilaginous Joints
- Description: Unite bones with hyaline cartilage.
- Characteristics: Immovable; ossify with age.
- Examples: Epiphyseal plates, manubrium of the sternum
Secondary Cartilaginous Joints
- Description: Resilient shock absorber using a layer of fibrocartilage on hyaline cartilage.
- Characteristics: Slightly movable; provides strength and flexibility.
- Examples: Intervertebral discs, pubic symphysis
Synovial Joints
- Synovial joints are the most common type in the human body
- They are freely movable (diarthroses)
- Structure includes a joint cavity filled with synovial fluid, articular cartilage covering the bone ends, an articular capsule, reinforcing ligaments, and nerves and blood vessels.
- The synovial fluid is a lubricant that reduces friction and nourishes the cartilage.
Disorders of Joints
- Sprains and dislocations are common joint injuries.
- Other disorders might involve inflammation or degeneration of the joint. Examples include bursitis, tendinitis, and arthritis.
Muscles
- The muscular system helps move substances, including food through the digestive system, blood through the circulatory system, fluids through the excretory system, and bones through the skeletal system.
- Three main types of muscle: skeletal muscles, cardiac muscles, and smooth muscles.
- Skeletal muscles are responsible for voluntary movements.
- Cardiac muscles are found only in the heart and contract involuntarily to pump blood.
- Smooth muscles are found in organs like the stomach, intestines, and blood vessels and control involuntary actions.
