Study Notes

Skeletal System: Gross Anatomy of Joints

  • Joints are the place where two or more bones or parts of the skeleton meet or connect.
  • Joints are classified by their movement and function.
  • Some joints have no movement (synarthroses), others have slight movement (amphiarthroses), and some are freely movable (diarthroses).
  • Joints' function is to give the skeleton mobility and hold the skeleton together.

Classification of Joints

  • Structurally, joints are classified by the type of connective tissue that binds the bones together.
    • Fibrous joints are held together by fibrous connective tissue (e.g., sutures, syndesmoses, gomphoses).
    • Cartilaginous joints are held together by cartilage (e.g., synchondroses, symphyses).
    • Synovial joints have a synovial cavity (e.g., planar, hinge, pivot, condyloid, saddle, ball-and-socket).

Movements at Synovial Joints

  • Body movement is when muscles contract across a joint, causing the insertion to move towards the origin.
  • Range of motion describes the possible movements at a joint.
    • Nonaxial movements involve gliding or slipping.
    • Uniaxial movements occur around one axis.
    • Biaxial movements occur around two axes.
    • Multiaxial movements occur around three axes.

Types of Synovial Joints

  • Planar (gliding): Flat articulating surfaces (e.g., intercarpal, intertarsal).
  • Hinge: One convex surface fits into a concave surface (e.g., elbow, knee).
  • Pivot: Rounded or pointed surface fits into a ring (e.g., atlanto-axial, radioulnar).
  • Condyloid: Oval-shaped projection fits into an oval-shaped depression (e.g., radiocarpal, metacarpophalangeal).
  • Saddle: Saddle-shaped surface fits into a saddle-shaped surface (e.g., carpometacarpal of the thumb).
  • Ball-and-socket: Spherical head fits into a cuplike socket (e.g., shoulder, hip).

Major Synovial Joints of the Body

  • Knee joint, Shoulder joint, Hip joint, Temporomandibular joint (TMJ).

Factors Stabilizing a Joint

  • The shape of the articular surfaces of bones determines possible movements.
  • Ligaments (elastic and fibrous) unite bones, preventing excessive or undesirable motion.
  • Muscle tone keeps tendons tight, contributing to joint stability.

Extra Structure of Synovial Joints

  • Bursae are flattened fibrous sacs lined with synovial membrane and containing synovial fluid, reducing friction.
  • Tendon sheaths are fibrous/membrane sheaths covering tendons.
  • Fat pads are accumulations of encapsulated adipose tissue giving support to the joint.

Clinical Application: TMJ Dislocation

  • Extreme mouth opening can lead to TMJ dislocation.
  • Condyle gets locked anteriorly, causing difficulty closing the mouth.
