What is the hip joint?
What is the hip joint?
The hip joint is a ball-and-socket joint. It allows for a wide range of movement in multiple directions while maintaining high stability due to its structure and surrounding ligaments.
What is the elbow joint?
What is the elbow joint?
The elbow joint is a hinge joint, allowing only flexion and extension. It is strengthened by ligaments like the annular, radial collateral, and ulnar collateral ligaments.
Describe the wrist joint.
Describe the wrist joint.
The wrist joint is a condyloid joint. It comprises two main joint surfaces: the radiocarpal joint between the radius and carpals, and the intercarpal joint between the carpal rows.

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.
