Types of Joints
- Synarthroses - immovable
- Amphiarthroses - very limited movement
- Diarthroses (synovial joints) - relatively free movement
= Monaxial
= Biaxial
= Triaxial
Movement of a body part toward the midline.
Movement of a body part away from the midline.

Bands of connective tissue that connect bone to bone and hold joints together.
Substance that lubricates synovial joints.
Synovial fluid
Sac containing synovial fluid that cushions adjacent structures.
Bones of the head, thorax, and spine.
Axial skeleton
Bones of the extremities, shoulder girdle, and pelvis (excepting the sacrum).
Appendicular skeleton
Triangular bone buried within the musculature of the upper back.
Bone that holds the scapula and shoulder joint at a fixed distance from the sternum and permits the shoulder to move up and down (shrug).
The single bone of the proximal upper extremity.
Bone on the thumb side of the forearm.
Bone on the little finger side of the forearm.
Proximal end of the ulna.
Bones of the wrist.
Carpal bones
Bones of the palm.
Bones of the fingers and toes.
Skeletal structure where the lower extremities are attach to the body.
One of the structures of the pelvis.
Large, flat innominate bone.
Irregular innominate bone.
Lateral bony ridge that is a landmark of the pelvis.
Iliac crest
One of the bony knobs of the posterior pelvis.
Ischial tuberosity
Large bone of the proximal lower extremity.
The larger bone of the lower leg that articulates with the femur.
The small bone of the lower leg.
The protuberance of the ankle.
The largest bone of the foot; the heel.
One of the bones forming the arch of the foot.
Small bundle of the muscle fibers.
Attachment of a muscle to a one that does not move (or experiences the least movement) when the muscle contracts.
Attachment of a muscle to a bone that moves when the muscle contracts.
Paring of muscles that permits extension and flexion of limbs.
Bands of connective tissue that attach muscle to bone.
Types of Muscular Injuries
- Contusion
- Compartment syndrome
- Penetrating injury
- Muscle fatigue
- Muscle cramp
- Muscle spasm
- Muscle strain
Condition in which a muscle's ability to respond to stimulation is lost or reduced through overactivity.
Muscle pain resulting from overactivity, lack of oxygen, and accumulation of wast products.
Intermittent or continuous contraction of a muscle.
Injury resulting from overstretching of muscle fibers.
Types of Joint Injury
- Sprain
- Subluxation
- Dislocation
Tearing of a joint capsule's connective tissues.
Types of Sprains
- Grade I - minor and incomplete capsule tear; painful, but minimal swelling; joint stable
- Grade II - significant by incomplete tear; moderate to severe pain, swelling; joint intact but unstable
- Grade III - complete tear; severe pain and spasm; joint unstable
Partial displacement of a bone end from its position in a joint capsule.
Complete displacement of a bone end from its position in a joint capsule.
A broken bone in which the bone ends or the forces that caused it do not penetrate the skin.
Closed fracture
A broken bone in which the bone ends or the forces that caused it penetrate the surrounding skin.
Open fracture
Types of Fractures
- Open
- Closed
- Hairline
- Impacted
- Transverse

Hairline fracture
Break in a bone in which the bone is compressed on itself.
Impacted fracture
A break that runs across a bone perpendicular to the bone's orientation.
Transverse fracture
Break in a bone running across it at an angle other than 90 degrees.
Oblique fracture
Fracture in which a bone is broken into several pieces.
Comminuted fracture
A curving break in a bone as may be caused by rotational forces.
Spiral fracture
Break in a bone associated with prlonged or repeated stress.
Fatigue fracture
