Study Notes
Anatomy of Joints
- Joints are the points where two or more bones meet
- Ligaments connect bones to each other, preventing dislocation and excessive movement
- Joints allow movement between bones
- Synovial joints are the most mobile type of joint
- Hyaline cartilage covers the articular surfaces, creating smooth surfaces for movement
- Synovial fluid lubricates the joint, minimizing friction and nourishing cartilage
- Joints contain ligaments and muscles that provide support and control stability
- Bones are joined to each other by fibrous tissues like Sutures, Syndesmosis, and Gomphosis
- Cartilaginous joints are of two types:
- Primary cartilaginous joints are temporary
- Secondary cartilaginous joints are permanent; Examples: intervertebral discs and symphysis pubis
- Different types of synovial joints:
- Hinge joints (elbow, ankle) move in one plane (flexion and extension)
- Ball and socket joints (hip, shoulder) allow all movements
- Plane (gliding) joints (intercarpal and intratarsal joints) allow sliding movements
- Pivot joints (superior radio-ulnar joint) allow rotation only
- Condylar joints (wrist) allow flexion, extension, abduction and adduction
- Saddle joints (thumb) allow greater range of movement.
- Stability of a synovial joint depends on the shape of bone surfaces, strength of ligaments and tone of surrounding muscles.
Types of Joints
-
Fibrous joints are immovable (sutures, syndesmoses, gomphoses)
- Sutures: connect bones of the skull (e.g., sutures of the skull)
- Syndesmoses: slightly moveable joints (e.g., inferior tibiofibular joint)
- Gomphoses: specialized fibrous joint (e.g., teeth fitting into the jaw)
-
Cartilaginous joints allow some movement (primary and secondary)
- Primary cartilaginous joints: are temporary (e.g., 1st sternocostal joint, epiphysis to diaphysis joints of growing bones, rib cartilage)
- Secondary cartilaginous joints: are permanent (e.g., intervertebral discs, symphysis pubis)
-
Synovial joints allow free movement (hinge, ball and socket, plane, pivot, condylar, saddle)
- Hinge joints: characterized by one plane of movement (elbow, knee)
- Ball and socket joints: allow full range of motion (shoulder, hip)
- Plane (gliding) joints: allow sliding movements (intercarpal and intertarsal joints)
- Pivot joints: allow rotation (superior radio-ulnar joint)
- Condylar joints: allow flexion, extension, abduction, and adduction (wrist joints)
- Saddle joints: allow greater range of movement (thumb joint)
